Retain the RPP teeth profile to guarantee an easy up-grade of the existing drives, in the spirit and concept of interchangeably which has identified, in the last years, our market approach philosophy. The new Megadyne RPP SILVER timing belt drive represents the most innovative and efficiente power system in the market thanks to its superior and unique structural and functional characteristics. Choosing RPP SILVER means choosing performing belts able to satisfy any power transmission requirements. Megadyne’s new RPP SILVER timing belt drive offers designers the utmost flexibility in the transmission design due to: 1. Increased performance (by 110% compared RPP standard); 2. the possibility to continue using the same RPP pulleys. 7 structure catalogo rppSILVER 20.09.04 25/10/05 17:17 Página 8 ISORAN RPP The new RPP SILVER is constructed with materials of the highest quality and strength. Extensive development performed by Research & Development has resulted in the homogeneous integration of all components, the cohesive bond of which imparts superior torque capacity giving the new RPP SILVER the possibility to provide the maximum performance in the market. 1 2 4 3 ISORAN SILVER STRUCTURE 1 THE BELT BODY It’s formed by an innovative compound. This cross-linked elastomer increases resistance to tooth shearing up to 15% in comparison to the previous Plus belts. This compound guarantees an exceptional level of resistance to flex fatigue preventing the appearance of cracks also with small pulley diameters. The results of tests made in accordance with the ASTM D813 showed an incredible improvement in the flex fatigue resistance over the previous standards. This compound is formulated also to better resist of mineral oils, heat and ozone actions. 2 TENSION MEMBERS • The glass fibre tensile members are the load carrying element in the new ISORAN RPP SILVER. • Thanks to the excellent characteristic of this cord the new ISORAN RPP SILVER has a superior tension stability in static and dynamic conditions. • The higher tensile strength and superior flexibility of the New ISORAN RPP SILVER belt confers weight saving, durability and maintenance free. 3 TOOTH FACING FABRIC A hard-wearing nylon fabric is bonded to the tooth surface to improve torque carrying capacity. In addition, a special graphite impregnation process confers self-lubricating action and increased drive efficiency on the belt. A pronounced improvement in belt performance results from the adoption of this system, which can be summarised as follows: • • • • • • 8 Better tension stability Longer life resistance Higher power performance More compact and lightweight drives with same power rating Exceptional resistance to abrasion and tooth shear No stocking and packaging constraints 25/10/05 17:17 Página 9 PROFILE New RPP SILVER features the proven reinforced parabolic profile RPP, illustrated in Figure1. The RPP belt profile, a deeper and more efficient belt tooth design, enables the belt to transmit more power, while occupying less space. structure catalogo rppSILVER 20.09.04 Figure 1 The reinforced parabolic profile of the new ISORAN RPP SILVER belt has an angle which increases from the base to the top of the tooth; this characteristic allows the use of a deeper profile compared to standard belts. The patented RPP parabolic profile grant the following advantages: a) A substantial reduction in noise compared to standard tooth profiles, and significantly lower than other deep tooth profiles; b) An improvement in tooth jump resistance. c) A substantial increase in torque and power transmission capabilities. d) Much higher resistance to tooth shear. e) Improved meshing characteristics, and reduced interference during tooth engagement and disengagement with the pulley. f) Reduced installation tension, leading to lower axial bearing loads. The recess at the top of the tooth. The tooth recess confers the following additional features to new ISORAN RPP SILVER belts: g) Controlled deformation of the softer top section of the tooth. h) Lower interference, and improved meshing characteristics. i) Less noise due to tooth impact during tooth mesh, and improved air discharge. j) Less wear due to friction. 9 features catalogo rppSILVER 20.09.04 25/10/05 17:17 Página 10 FEATURES The new ISORAN RPP SILVER can be really consider a reliable, lower maintenance and economical alternative to drive systems equipped with chains and gears. Thanks to its “state of the art” materials, the new ISORAN RPP SILVER is particularly recommended for efficient, compact drives which experience high torque loading, and permit the designer much greater flexibility by means of the following advantages: • Increases load carrying capacity by up to 10% compared to previous RPP Plus, and more than 110% compared to the Standard RPP. • Uses existing RPP pulleys, which maintains functional interchangeability with other deep profile systems as HTD. • Allows existing systems to be upgraded without the necessity to replace the pulleys. Because the new ISORAN RPP SILVER retains the already proven RPP belt profile (recognised as the quie test system on the market), it possesses all the known advantages of low noise of the RPP belt profile. In addition to this it has the extra advantages of: • Further reduction of noise by reduced belt widths due to the higher performance rating of the system. • Low noise characteristics compared to drive systems using polyurethane, steel etc due to the rubber construction. • Use of smaller pulleys creates lower belt speeds and thereby less noise. • Under the same transmission conditions the new ISORAN RPP SILVER has the same noise level of the previous generation. 10 25/10/05 17:17 Página 11 BELT SPECIFICATION A New ISORAN RPP SILVER belt is defined by the following parameters: BELT PITCH: the distance in millimetres between two adjacent tooth centres as measured along the pitch line of the belt. BELT PITCH LENGTH: the total length (circumference) of the belt in millimetres as measured along the pitch line. (the theoretical pitch line of a New SILVER belt lies within the tensile member) The pitch length is a parameter that identify univocally a synchronous drive belt. To measure a belt is necessary to use a suitable measuring equipment as specified in the standard ISO/FDIS 13050:1999(E). All data not directly reported can be referred to this mentioned standard. belt specification catalogo rppSILVER 20.09.04 BELT WIDTH: the width of the belt measured in millimetres. p Pitch line Ou ts id e di am et er p er Pitch diamet a Pitch circle Figure 2 The nominal belt tooth dimensions are given in Table A1 and shown in Figure 2 Pb Pb w a w a PITCH LINE PITCH LINE y rr ht hs β β ht x S S Table A1 Belt type hd y rr Pitch ß S hs 8 M 8 mm 32° 5.5 14 M 14 mm 32° 9.5 8 M-DD 8 mm 32° 5.5 14 M-DD 14 mm 32° 9.5 hd ht rr a 5.4 3.2 1.00 0.686 9.7 6.0 1.75 1.397 7.8 3.2 1.00 0.686 14.5 6.0 1.75 1.397 11 STANDArD BELT RANGE catalogo rppSILVER 20.09.04 12 25/10/05 17:17 Página 12 STANDARD BELT RANGE New Silver belts are manufactured in 8 and 14mm pitches; on request can be provided also in the double sided version.

d) Layout data: maximum pulley diameters, approximate pulley centre distance and tolerance. STEP 1 CALCULATION OF POWER TRANSMITTED a) From table 1 select the appropriate Service Factor Fs according to: • the type of the driveN machine; • the class of the prime mover; • the service conditions (duty cycle category). b) In case you are designing a drive with a speed up ratio (i = n driveR/ n driveN <0.8) you need to add at the above mentioned service factor Fs also the correction factor Cm as reported in Table 2: TABLE 2 – Speed up factor Cm Cm ≥0.8 0 0.79÷0.58 +0.1 0.57÷0.40 +0.2 0.39÷0.28 +0.3 <0.28 +0.4 c) Then the corrected service factor Cc is calculated as follows Cc = Fs + Cm [1] d) The design power is obtained multiplying the input power by the corrected service factor: Pc = P x Cc [2] 18 25/10/05 17:18 Página 19 Table 1- Service Factor Fs DRIVE R MACHINE CLASS A CLASS B CLASS C Peak overload up to 149% of rated load Peak overload from 150% to 249% of rated load Peak overload from 250% to 400% of rated load • AC Motor: Asynchronous Star-Delta starting • DC Motor: Shunt wound • Internal combustion engines: 8 cyl. and up • AC Motor: Asynchronous: Direct switch starting Synchronous: Normal torque • DC Motor: Compound wound • Internal combustion engines: 6 cyl. • AC Motor: Single Phase: all Asynchronous: Double cage motor Synchronous: High torque • DC Motor: Series wound • Internal combustion engines: 4 cyl. or under • Hydraulic motors, line shafts Duty cycle category Intermittent service Normal service Continuous service Intermittent service Normal service Continuous service Intermittent service Normal service Continuous service < 8 hours daily 8 to 16 hours daily >16 hours daily < 8 hours daily 8 to 16 hours daily >16 hours daily < 8 hours daily 8 to 16 hours daily >16 hours daily Category 1: LOW UNIFORM LOAD/TORQUE Office equipment; Measuring equipment; Instrumentation; Display equipment; Laundry machinery: general; Line shaft; Agitators, mixers for liquid; Bakery machines.

DRIVE CALCULATION PROCEDURE catalogo rppSILVER 20.09.04 Note: These service factors are adequate for most belt drive applications. Service factors can be substituted only when the input data and working conditions are exactly known. In this case service factors may be adjusted based upon an understanding of the severity of actual drive operating conditions. 19 25/10/05 17:18 Página 20 STEP 2 DETERMINE THE BELT PITCH The belt pitch can be selected from graph 1, using: • the design power (Pc) obtained in Step 1-d • the rpm of the faster shaft (smaller pulley) in the drive. SILVER 8 SILVER 14 SI LV ER 8/1 4 DRIVE CALCULATION PROCEDURE catalogo rppSILVER 20.09.04 Locate the design power along the X-axis of the graph. Read up to the rpm of the faster shaft; the belt pitch indicated in the area surrounding the point of intersection which you located is the one you should use for your design. If the point of intersection falls outside of any specific area, please contact your Megadyne technical Department. If the point falls in the intersection area of 8mm and 14mm, a good drive can likely be designed using either belt pitch. We suggest to design the drive using both belt pitches and select the drive best meeting your size requirements or the most economical drive. 20 25/10/05 17:18 Página 21 STEP 3 SELECTION OF BELT, PULLEYS AND CENTRE DISTANCES a) Determine Speed Ratio (R) by dividing the rpm of the faster shaft by the rpm of the slower shaft: b) Refer to the centre distance selection table 3 (pag 38 to 49) to determine which pulley combinations give the desired speed ratio. The most suitable pulley combination can then be selected eliminating any pulley combination for which the required centre distance cannot be obtained with the nearest standard belt size. If you know exactly the drive centre distance and the driver and driven diameters, you can calculate the belt pitch length with the following formula: DRIVE CALCULATION PROCEDURE catalogo rppSILVER 20.09.04 c) Check that the ratio of the belt teeth number and the pulleys teeth is not an integer number. If this happens it’s necessary to modify the drive where possible (centre distance, ratio, pulley diameter) otherwise the belt life could be strongly reduced. d) The final pulley combination is then selected based upon the priorities required from the particular drive, in terms of flexibility in driven speed, centre distance, drive cost, etc... 21 DRIVE CALCULATION PROCEDURE catalogo rppSILVER 20.09.04 25/10/05 17:18 Página 22 STEP 4 DETERMINE THE ACTUAL POWER RATING Pba The Actual Power rating is obtained by the following formula: a) Calculation of Cd factor Power ratings listed in this handbook are based on a minimum of six teeth in mesh between the belt and the pulley. The ratings must be corrected for excessive tooth loading if there are less than six teeth in mesh. To determine the number of teeth in mesh on the smaller pulley you can use the following formula: If Zt is greater than 6, Cd =1 If Zt is less than 6, the value of Cd must be obtained from table 4. Table 4 - Teeth in mesh factor Cd 22 Number of teeth in mesh Cd 6 or more 1.00 5 0.80 4 0.60 3 0.40 2 0.20 25/10/05 17:18 Página 23 b) Calculation of K1 factor The power ratings listed in this catalogue are based on specific belt lengths. To consider the influence of different belt lengths you have to use the corrective factor K1 in Table 5.

It’s recommended to select the next higher standard width (see table 8) in bold. Table 8 - Belt width factor Cw Belt width [mm] SILVER 8 10 20 25 30 40 50 55 75 85 100 115 170 0.500 1.000 1.250 1.500 2.000 2.500 2.750 3.750 4.250 SILVER 14 0.500 0.625 0.750 1.000 1.250 1.375 1.875 2.125 2.500 2.875 4.250 c) Once the belt width is defined, is possible to calculate the “Drive Safety Factor” as follows: Where the Effective Belt Power Rating can be calculated multiplying the Actual Power Rating (Pba) by the belt width correction factor Cw listed in Table 8 corresponding to the selected belt width. The Drive Safety Factor gives to the designer an indication of the maximum extra load that the drive can tolerate. 24 25/10/05 17:18 Página 25 STEP 6 STATIC TENSION CALCULATION When installing a New ISORAN RPP Silver, the belt tension is chosen so as to avoid: • TOOTH JUMP. Assure that the belt is tensioned adequately to prevent tooth jump under the most severe load conditions that the drive will encounter. • EXTREMELY HIGH BELT TENSION. Avoid extremely high tension which results in elevated noise levels and reduced belt and bearing life. The required static tension is obtained by the following formula: DRIVE CALCULATION PROCEDURE catalogo rppSILVER 20.09.04 a) Determination of Km factor To consider the influence of the peak torque of the motor used, you have to use the corrective factor Km as listed in Table 12. Table 12 - Class of motor factor Km Class A Class B Class C 1.35 1.5 1.75 b) Calculate the belt linear speed To determine the belt linear speed of the transmission you can use the following formula: 25 DRIVE CALCULATION PROCEDURE catalogo rppSILVER 20.09.04 25/10/05 17:18 Página 26 c) Determination of the belt mass (m) The belt mass per unit length (m) for a particular belt pitch and width can be obtained from table 13. Table 13 - belt mass per unit length m Pitch [mm] Belt width [mm] m [Kg/m] 10 0.057 20 0.115 30 0.172 8 50 0.286 85 0.487 20 0.202 40 0.404 14 85 0.858 115 1.160 170 1.715 d) Static Tension calculation It’s possible now to calculate the static tension using the formula [9] described at the beginning of this Step. Note: For unusual , shock or pulsating loads consult Megadyne application Engineering Department for guidance. To calculate the static axial load Fa please refer to the following formula: STEP 7 STATIC TENSION CONTROL There are two methods to measure the correct static tension: a) The elongation method b) The vibration method a) The elongation method The elongation procedure for determining the correct belt tension is based on measuring the force to deflect one span of the belt by a given amount (see figure below). 26 25/10/05 17:18 Página 27 a1) Free span length calculation Determine the free span length (t) of the belt. The value of (t) can be found using the following formula: a2) Deflection forces Calculate the minimum and maximum deflection forces by means of the following formulas: DRIVE CALCULATION PROCEDURE catalogo rppSILVER 20.09.04 a3) Deflection distance Calculate the deflection distance by means of the following formula: - With the belt installed on the drive and tensioned to a level required to eliminate all slack in the system (snug fit) begin the tensioning procedure. At the centre of the span (t), apply a force perpendicular to the span so that the belt is deflected by the deflection distance (f) from its normal position. Make sure that at least one pulley is free to rotate. For belts wider than 50 mm, place a section of rigid material such as a length of key stock across the belt and apply the force through this rigid member to prevent belt distortion and insure proper tensioning. - Compare the deflection force with the range of forces calculated in anterior steps. • If this is less than the minimum deflection force, the belt should be tightened. • If this is greater than the maximum deflection force, the belt should be slackened slightly. 27 DRIVE CALCULATION PROCEDURE catalogo rppSILVER 20.09.04 28 25/10/05 17:18 Página 28 b) The vibration method An alternative procedure to measure the tension of the belt is to use a Belt Tension Gauging Equipment. This device consists of a small sensing head which is held across the belt to be measured. The belt is then tapped to induce the belt to vibrate at its natural frequency. The vibrations are detected and the frequency of vibration is then displayed on the measuring unit. The relation between belt static tension (Ts) and frequency of vibration (f) may be calculated using the following formula: 25/10/05 17:18 Página 29 EXAMPLE: BASIC DESIGN DATA Motor Power DriveR rpm Class motor P = 5 kW n1 = 2000 rpm Class C Application Absorbed power DriveN rpm Textile machine Unknown (assume 5 kW) n2 = 1000 rpm Type of driveN machine Working hours Not uniform torque (Category 3) 8-16 hours/day Approximate centre distance Maximum pulley diameter 630 - 640 mm 250 mm Step 1.

The dynamic axial load is obtained by a vector addition between the tension in the tight span (T1) and the slack span (T2) as shown in the figure 3. The formula to calculate the dynamic axial load is the following: Where: Te = Effective belt tension (T1-T2) [N] Ts = Static tension [N] ß = Wrap angle on small pulley [°] a) The effective belt

by Megadyne along with those of the belts, are the determining factors in the perfect functioning of the drive. The introduction of the parabolic profile on the new ISORAN RPP pulleys can be considered an evolution in the design of timing pulleys. The trend in design is towards more compact drives. The standard tooth profile has shown poor performance with reduced pulley diametres. The new drive design is more compact therefore it is necessary to use pulleys with smaller diameters. Producing the pulleys according to traditional procedures the following limitation can be found. Decreasing the diameter of the pulley, the profile of the groove forms an edge at the tip radius (fig.6). This brings about: a) reduction of the contact surface between the belt and the pulley, the teeth and therefore a local increase of stress (fig.8); b) more wear of the belt at the base of the tooth. For building RPP pulleys with parabolic profile Megadyne has patented a system which permits constant profiles even by reduced diameters and free from discontinuity on the top of the tooth (fig.7). Therefore: 1. The new ISORAN RPP pulleys allows a larger contact surface with the tooth of the belt (fig.9); 2. the new ISORAN RPP pulley reduces belt wear during mesh. ISORAN RPP pulleys are also used with RPP SILVER belts, as mentioned above. This gives advantages in terms of availability and supply, and at the same time allows drives to be upgraded where belt drive durability problems have been experienced. As consequence our RPP pulleys offers the designers the flexibility to choose between a huge range of different performing belts without the necessity to change the pulleys. 62 25/10/05 17:19 Página 63 Megadyne RPP pulleys are constructed from high quality materials, and manufactured under high standards of quality control with particular attention to the tight dimensional tolerances required. The pulley teeth are designed to mesh and conform exactly to those of the belt, resulting in a drive which functions with a minimum backlash as a precision gear system. Extensive testing and market feedback confirms the reliable nature of the RPP SILVER system. When ISORAN RPP pulleys are used with RPP SILVER belts the drive efficiency can be further improved by considering the following advantages: 1. The pulley width can be reduced whilst transmitting the same torque; 2. alternatively there is the possibility to reduce the pulley diameters whilst maintaining the same belt width; 3. by using the same pulleys as used with an ISORAN RPP drive, the torque transmitted can be increased or the drive durability can be extended. An ISORAN RPP pulley is designated by: a) - Number of teeth b) - Pitch of the pulley teeth c) - Width of the pulley RPP PULLEYS FEATURES catalogo rppSILVER 20.09.04 The pitch of the pulley teeth is the distance between tooth centres as measured along the pulley's pitch circle diameter (PCD). The PCD of the pulley coincides with the pitch line of the belt, and is therefore always larger than the outside diameter of the pulley. RPP pulleys are stocked in 8 mm and 14 mm pitches. Standard pulleys sizes are listed in table 14. A typical pulley designation is detailed below: 40-RPP14-55 Where: d) 40 = Number of pulley teeth e) RPP = Tooth profile f) 14 = Tooth pitch in millimetres g) 55 = Corresponding belt width in millimetres All standard pulleys are designed, where possible, to be used in conjunction with taper-bushes, and for each pulley size it is necessary to select the correct taper-bush. The use of taper-bushes allows each pulley to be fitted to a variety of shaft sizes without the need to machine or otherwise modify the pulley beforehand. Pulleys are available with Taper-bushes fit both metric or imperial (inch sized) shafts. However, for high torque applications, is not recommended to use standard bushes because severe tension conditions can be reached under particular circumstances, in case of driven shaft rapid blockage

Differences of not more than 0.01 mm for every 10 mm of axis length are acceptable. TAPER The taper of the pulley face diameter must be less than 0.001 mm for every 1 mm of face width. this value must be less than the tolerance on the external diameter of the pulley given in table 15. SURFACE FINISH The working surface of the pulley and flange faces must have a finish of less than 1.6 Ra (ISO R 468 specification) Material To right choice of material depends on the torque to be transmitted and on the size of the pulley.

If this procedure is not followed, the drive life and efficiency may be considerably reduced. The most frequent problems encountered, together with their probable causes, are listed in the table below. We hope that this will serve as a useful quick-reference guide, but if the drive problems persist or if they are not identified in the following list please consult MEGADYNE . Problems Causes Corrective action Abnormal wear of the belt: 1. on the side of the tooth • Belt excessively taut • Excessive overloading • Incorrect contour or diameter of pulley • Reduce centre distance • Use a wider belt • Replace pulley after checking contour or diameter 2. on the bottom of the tooth • Excessive installation tension • Reduce centre distance 3. at the tooth root • Incorrect diameter of pulley • Replace pulley after checking diameter 4. on the side of the belt • Incorrect contour or diameter of pulley • Replace pulley after checking contour or diameter • Misalignment or wrong setting of pulleys • Replace pulley after checking contour or diameter • Oscillation of the axes and/or of the bearings • Correct the positioning of the pulleys and reinforce the bearings • Flanges bent • Straighten flanges Failure through traction or through laceration of the teeth, indicating corrosion of the tension member • Diameter of small pulley i.e. below the minimum • Excessive moisture • Increase the diameter of the pulleys or use belts and pulleys of smaller pitch • Eliminate the moisture Laceration of belt teeth • Number of teeth in mesh less than six • Excessive load • Increase the number of teeth in mesh or use belts and pulleys of smaller pitch • Use a wider belt Rupture of tensile member • Excessive load • Diameter of pulley below minimum • Use a wider belt • Increase the diameter of the pulleys Breaks or cracks in the top surface of the belt • Exposure to excessively low temperatures (below -25°C) • Eliminate the low temperature Softening of the top surface of the belt • Exposure to excessively high temperatures (over +85°C) or operation with excessive amount of oil present • Eliminate the high temperature or reduce the amount of oil present Apparent elongation of the belt • Reduction of centre distance due to bearings not being firmly fixed • Restore the initial centre distance and strengthen the bearings Belt overriding the flanges • Faulty installation of the flanges • Misalignment of pulleys • Reinstall the flanges properly • Align pulleys Excessive wear of pulley teeth • Excessive overloading • Belt excessively taut • Pulley material insufficient hard • Use a wider belt • Reduce the centre distance • Harden the pulley surface Drive excessively noisy • • • • • • • • Pulleys out of line Excessive installation tension Excessive load Diameter of pulley below minimum Align pulleys Reduce the centre distance Use a wider belt Increase the diameter of the pulleys 25/10/05 17:19 Página 69 SPROCKET DIAMETER AND SPEED Blanks in the Belt Basic Performance Tables indicate the pulley speeds exceed the safe operating speed of 30m/s for cast iron sprockets. For speeds greater than 30m/s contact Megadyne Engineering Department for other recommendations. FLANGED PULLEYS Each timing belt shows a natural trend to run on the pulley; this behaviour is due to the typical construction of the tensile members. Each cord is made of a few hundreds of filaments winded together to make a unique bundle and few bundles are twisted together. The twisting direction produces the lateral tracking off. A timing belt is produced with two different type of twisted cord to minimize this effect, nevertheless only using flanged pulleys is possible to prevent synchronous drive belts from tracking off. It is necessary to provide at least one toothed pulley with side flanges. This is normally the smaller one for reason of cost. In alternative is also possible to use a single sided flange on each pulley. In the case of drives with a centre distance of ≥ 8 dw, both toothed pulley are required to be equipped with flanges on both sides. The shape and dimension of these flanges are shown in the table 19 and figure below.

For example: 1. in fixed axes drives, as a tensioning device; 2. in the drives having a high drive ratio, to increase the arc of contact on the small pulley. Furthermore, the tensioner: a) shall have a diameter not lower than the one of the smaller pulley; b) may be fitted both inside and outside the belt, although we recommend whenever possible that it be fitted inside; c) if fitted outside, it must have a flat face (not crowned); d) if fitted inside, it must be toothed. The use of normal tensioners with a flat face is permitted, as long as its diameter is not lower than that of a pulley having 40 teeth. Fixed centres (no adjustmen) True fixed centre applications are those where no provision has been made to adjust either the driveR or the driveN shaft. Fixed centres are not recommended for any synchronous belt drive other than motion transfer (low or no torque) drives. Fixed centres applications imply the need for exact tolerances. Although length tolerances for synchronous belts are considerably less than those for other belts, such as v-belts, etc., no belt can be manufactured without some tolerance. Sprocket manufacturing tolerances also contribute to fixed centre drive problems. Fixed centre applications do not allow for proper belt installation and tensioning practices and prevent accepted maintenance procedures. Because fixed centre applications prevent proper belt installation and tensioning procedures, reduced belt performance can result. Anymore if there is no possibility to use an idler or a tensioning device, contact Megadyne Engineering Department.
