DESCH V-Belt pulleys - Screw
DESCH V-belt pulleys Screw-on hubs, Welded hubs KS 12 – GB V-belt pulley V-belt drives are frictionally engaged traction mechanism gears consisting in their simplest form of two V-belt pulleys and V-belts. Transmission ratios of 8:1 to 1:8 are possible with a power of up to 1000 kW. With an extensive calculation program we determine the economically optimum drive from the large number of combinations which are technical feasible. Prices and delivery times are favourable if V-belt pulleys from the range in stock can be used. DESCH V-belt pulleys The DESCH V-belt pulleys have many advantages: quiet running; good damping of impact torques and rotary vibrations; rupture safety because V-belts slip at over load; easy assembling; low-maintenance. In normal case DESCH pulleys are of the material EN-GJL 200 and are standardised on the basis of DIN 2211 and 2217 respectively. V-belt pulleys with cylindrical hole are balanced on one level quality grade G 16 according to DIN ISO 1940; dw < 400 mm with an operating speed n = 1500 rpm; dw > 400 mm with v = 30 m/s. Pulleys for taper bushes correspond to quality grade G 3 according to DIN ISO 1940 balanced on one level; for dw < 400 mm with n = 1.500 rpm; for dw > 400 mm with v = 30 m/s. The balancing is performed without groove on a smooth balancing mandrel, which corresponds to the half-wedge balancing mode. Other types of balancing, such as full-wedge, by agreement. We recommend: balancing on 2 levels G 6.3 for operating speed if the circumferential speed is v > 30 m/s or the dw b2 ratio is < 4 and v is > 20 m/s. If nothing different is indicated, the ready-drilled holes of the V-belt pulleys are given a tolerance of H7 and are grooved for feather keys according to DIN 6885/1. Max. outside diameter of pulleys 3.500 mm.

Do not go below minimum pulley diameter (p.8) (service life, economic efficiency) 2. Use standardised pulley diameter. Select a standardised diameter at least for the largest pulley of the drive. 3. Note belt speed or max. circumfe- rential speed of belt pulley. For higher speeds other material grades can be supplied. 4. Special design possible. In addition to V-belts for a wide variety of profiles, we sell narrow V belts to DIN 7753, Part 1 (Fig.1) and USA Standard RMA/ MPTA in covered and raw-edged design (Fig.3), compound V-belts (Fig.4) and V-belts according to DIN 2215 (Fig.2). The latter are not economic and should no longer be used in new designs. V-belts manufactured in series are resistant to oils and greases provided these are only present in small quantities, they are heatresistant to 70°C ambient temperature, electrically conductive and dust-proof. Taper bushes with groove according to DIN 6885, Part 1 DESCH Taper bushes are used to fasten pulleys or coulpings to shaft. In the case of V-belt pulleys this fastening is generally sufficient to transmit the power. An additional feather key connection is only necessary with extremely high load. Each taper bush is equipped with a feather key groove for this purpose. The bushes can be used with shaft tolerances of up to h11 with max. diameter of 30mm. Beyond this up to h9. Detailed installation instructions are enclosed with each delivery.

5050 5050 5050 Weld-on Hub Taper welded nubs are made of steel, drilled, countersunk and given a taper hole to enable them to be mounted with standard taper bushes. The protruding flange provides a convenient possibility of welding hubs in fans, fanwheels, steel disks, chain wheel pulleys and many other devices which have to be mounted permanently on a shaft. Welded hubs are simple to install and are ideally suitable where heavy-duty conditions are encountered. When the bolts are tightened, the hole is pressed together, thus fastening it on the shaft in the form of a press fit. The type of design eliminates all mounting difficulties, as well as preventing any loosening and migration on the hub during operation.
