Basic Information
WARRANTY AND SAFETY NOTES
GEAR DRIVE IDENTIFICATION
Falk Gear Drives
The Falk name on the gear drive is the purchaser’s assurance that the
drive was engineered, rated and manufactured to sound gear
practices.
Gear drives in this bulletin, nameplate data and customer orders
identified by the following nomenclature. Use the appropriate
designations
when placing an order or making an inquiry.
Warranties and Safety Codes
Refer below for warranty information
and to Terms
standard conditions of sale and limits of liability.
loo-603
284 AF
-------
Install and operate Falk products in conformance with applicable
local and national safety codes and per Falk installation
manuals
which are available upon request. Suitable guards for rotating members may be purchased from Falk as optional accessories. Consult
your local Falk Representative
for complete details.
CAUTION:
Lock out power source and remove all external loads
from unit before servicing unit or accessories. Locking out the
power source and removing the load will reduce the possibility of an
unexpected motion or reaction in the system.
People Conveying
Equipment
If people are occasionally transported
in applications such as conveyors, cranes or hoists, refer to Factory for the selection of the gear
drive, the proper size coupling and availability
of the dual path
coupling feature that will meet applicable safety codes. Selection
of Falk products for applications such as freight or passenger elevators, escalators, man lifts, work lift platforms and ski tow and ski
lifts are not approved.
GEAR DRIVE RATINGS
All gear drive ratings in this bulletin allow 100% overload for
starting
loads and momentary
overloads for electric motor
driven applications
operating
10 hours per day under uniform
load conditions
(unity Service Factor). For other conditions, compute an equivalent horsepower by multiplying the actual horsepower
required for the application by the appropriate
Service Factor.
Horsepower
TYPE
for
When one prime mover drives two pieces of equipment, one of
which is either a standard Falk geared drive or a customer standard geared drive, the division of power between each machine is
the responsibility of the customer. The power supplied to the geared
drive must be equal to or less than the power for which the unit was
selected using the appropriate
service factor for the application.
The customer must also assume the responsibility
of isolating the
geared drive from any vibratory or transient load induced by the
driven equipment.
Gear drive mechanical horsepower
and torque ratings
in the catalog to permit selections for specific application
are tabulated
requirements.
Thermal Horsepower
Thermal ratings need not be considered when the continuous
operating period does not exceed three hours and the shutdown
time equals or exceeds the running time. However, when the running
time exceeds the shutdown time, selection must be made on a
basis of adequate thermal rating.
Checking the thermal horsepower
is extremely important, for if
the unit creates heat faster than it can be dissipated, severe damage
may occur.

Temperature
Gear drives can encounter up to lOOoF (55OC)
temperature rise over
ambient, with oil sump temperatures
up to 200°F
(93OC) and
higher in localized areas. Since the unit will feel hot to the human
hand at temperatures
over 120°F (49OC), a portable pyrometer
should be used to measure temperatures.

IDENTIFICATION
Accessories for Types AFH & AFX units shown in this bulletin and
customer orders are identified by the following nomenclature. Use
the appropriate
designations
when placing an order or making
an inquiry.
Thermal horsepower
is the actual horsepower (without Service
Factor) that a gear drive will transmit continually for three hours
or more without overheating.

Conditions Affecting Selections
Non-Standard Application Procedures
The following conditions may affect the unit selection
size and auxiliary equipment being furnished.
procedure,
unit
Excessive Overloads-The
maximum momentary or starting load
must not exceed 200% of rated load (100% overload). Rated load
is defined as unit rating with a Service Factor of 1.0. If the maximum
starting or momentary load exceeds the above conditions, compute a second equivalent horsepower
by dividing the peak load by
two. The gear drive selected must have capacity equal to, or in
excess of, the larger equivalent horsepower.
Reversing
Service - Applications
involving either more than 20
reversals per 10 hour period, or less than 20 reversals per 10 hour
period with peak torques greater than 200% of normal load must be
referred to the Factory.
Brake Equipped ApplicationsWhen a gear drive is equipped with
a “working”
brake that is used to decelerate the motion of the
system and the brake is located between the prime mover and the
gear drive, select the drive based on the brake rating or the highest
equivalent horsepower, whichever is greater. If the brake is used for
holding only and is applied after the motion of the system has
come to rest, the brake rating must be less than 200% of the catalog
rating of the gear drive selected for the application. If the brake
rating is greater than 200% of the gear drive catalog rating, refer the
application to the Factory. Also refer to the Factory all applications
in which the brake is located on the output shaft of the gear drive.
Oversize
Prime Movers - Published Service Factors do not cover
applications that require oversize prime movers for high energy or
peak loads. Refer such applications to the Factory for selection of
suitable drives.
Refer all variable and multi-speed applications to the Factory. They
may require special consideration to provide adequate lubrication
at the slowest speed, but ‘without excessive heating or churning at
the highest speed. It is essential that all orders indicate minimum
and maximum speeds, as well as the speed duration cycles.
Effects of Solar EnergyIf a drive operates in the sun at ambient
temperatures
over lOOoF (38OC), then special measures should be
taken to protect the drive from solar energy. This protection can
consist of a canopy over the drive or reflective paint on the drive. If
neither is possible, a heat exchanger or other cooling device may be
required to prevent the sump temperature from exceeding the
allowable maximum of 200°F
(93OC.).
Overhung
Loads and Thrust
Loads-The
overhung load and thrust
ratings published in this bulletin are based on a combination of the
most unfavorable
conditions of rotation, speed, direction of applied
load and unit loading. If the calculated load exceeds the published
value, or if an overhung load and thrust load are applied simultaneously to a shaft, refer complete application information
to the
Factory. For more information,
refer to tables and guidelines on Pages
16 through 20.
Product Modifications
- Falk can supply special product modifications to suit your application needs. Contact your local Falk
representative
for housing modifications,
special ratios, special shafts,
special mounting conditions, accessory modifications
and other
special application requirements.
Speed Variation -When
selecting gear drives for multi-speed or
variable speed applications, determine the speed which develops
the greatest torque and select the gear drives on this basis. If
the speed is not listed in the selection table, use the next lower
output speed.
Selections for Non-NEMA
Motors-After
determining the correct
unit size by using standard selection procedures, determine which
T-frame motor listed in the table below is dimensionally
equal to or
larger than the substitute motor. If the T-frame size does not exceed
the maximum listed in the table at right, a standard motor bracket can
be used with appropriate
shim blocks. If the substitute motor is
dimensionally
too large for the unit selected, use a larger unit with
a bracket that will accept the substitute motor, or use a motor plate,
or consider the use of a semi-standard
or special motor bracket.

Service Factors for paper mill applications
are applied to the nameplate
rating
of the electric drive motor at the motor rated base speed and are consistent
with those shown in TAPPI standards.
Anti-friction
bearings only.
A service factor of 1.00 may be applied at base speed of a super calender
operating over a speed range of part constant hp and part constant torque where
the constant hp speed range is greater than 1.5 to 1. A service factor of 1.25
is applicable
to super calenders operating
at constant torque over the entire
speed range or where the constant hp speed range is less than 1.5 to 1.

1750 rpm electric motor. Select a vertical right angle speed reducer
for the application.
1. Service Factor is 1.50 for a large mine fan operating
day.. . Page 9, Table 3.
2. Equivalent
hp = 1.50 x 150 = 225
16 hours per
. . . See How to Select, Page 8.
3. Required Ratio = 1750 + 190 = 9.21 . . . closest standard
ratio is 9.30..
. Double Reduction Selection Table, Page 11.

4. Unit size is 357AFXU2..
. Double Reduction Selection Table. In
the 1750 high speed shaft section, opposite 9.30 ratio, trace right
to 285 (nearest hp exceeding equivalent hp) and read unit size 357
at top of column. Add “U” to Type “AFX” to indicate that L.S.
shaft extension required is “Up” and add “2” for double reduction.
5. Unit requires fan cooling . . . thermal rating of unit without fan is
77 hp from Page 15; 150 hp is required (transmitted
load without
service factor). Thermal rating with fan is 157 hp.
6. Check overhung
loads and thrust
loads, Pages 16-20.
7. Check unit and accessory dimensions,
Pages 21-26. If a motor
bracket, “C” face motor adapter or motor mount is required,
specify an electric fan.

0 When selecting unit by hp method, check required hp (without
service factor) against thermal hp ratings on Page 15. When selecting unit by torque method, convert required
torque (without
service factor) to hp and check against thermal
hp ratings on Page 15. For ratings at speeds higher than 1750 rpm, consult the Factory or local Falk
Representative.
For hp ratings at speeds below 580 rpm, reduce hp rating proportionately.
For torque ratings at speeds below 580 rpm, use torques for 580 rpm.

Electric Cooling Fans
Electric fans provide an economical means of cooling when
full use of H.S. shaft usable shaft length is required for
accessories such as Motor Brackets, “C” Face Motor
Adapters or Motor Mounts. Electric fans can be thermostatically controlled to shut off when not required. Standard
fan motors are 220V single phase. For other motors,
consult Factory.

Low Speed Shaft
Calculate low speed shaft overhung load using the formula
and Fc values at left. The Lf load location factors on Page 17 are
based on the distance from the center line of the load to the
reducer seal cage.
Low speed shaft overhung
load example -An application
requiring 115 hp is driven by a 357AFX2
unit with 68 rpm output.
An 18” pitch diameter single-chain sprocket is mounted on the low
speed shaft up and the center line of the load is 5 inches from
the seal cage. Calculate the overhung load.
Overhung
Locate the center line of the load as close to the reducer
seal cage as practical to minimize the overhung load and
increase bearing life. The above overhung load formula employs
the transmitted horsepower, without Service Factor, providing
the overloads, starting loads and brake capacities do not exceed
the amounts listed in Gear Drive Ratings on Pages 6 and 7.
Consult Factory for Higher Overhung
Load RatingsIn
many cases, overhung load capacity in excess of that published
is available. Published ratings are based on a combination of the
most unfavorable conditions of rotation, speed, direction of
applied load, and unit loading. If the actual load should exceed
Load =
126,000
x 115 x 1.0 x .97
18 x 68
= 11,483 pounds
Refer to the solid shaft up overhung load table on Page 17 and note
that the overhung load capacity for the 357AFX2
at 68 rpm
is 16,300 pounds (16.3 x 1000) and is satisfactory for this selection.
High Speed Shaft
Calculate high speed shaft overhung load using the formula and
F, at left. Lf load location factors tabulated on Page 19 are
based on the distance from the center line of the load to the
reducer seal cage for units without fan or to fan hub for units with
shaft driven fan. Check the result against the rating on Page 20.
Higher overhung load capacities are available when the full
unit torque rating is not utilized. Refer to the Factory for higher ratings.
