FARR Couplings

FARR Coupling Overview and Performance Data The FARR Coupling is used when a rigid connection is required between the low speed shaft of a gearbox and the head shaft of a conveyor, bucket elevator, mixer or any overhung or suspended load. When sized properly, the FARR Coupling will carry the application torque, weight of gearbox, motor and swing plate. In the case of a mixer, it will carry the weight of the shaft and impeller, thrust forces and resulting bending moments. Components of a FARR Coupling consist of male and female piloted hubs made from 4140 alloy steel. The hubs are extended to...

FARR Coupling Dimensional Data FARR Dimensional Data G Max Rough Stock Notes: n 1 Indicates: Total coupling weight with one maximum bore hub and one Rough Stock Bore hub. n Interference Bores are standard unless otherwise specified. n Bores and Keyways are machined to meet dimension tolerances defined in ANSI / AGMA 9002-B04 for inch and ISO 286-2 for metric.

FARR Coupling Selection Guide A. Obtain The Following Information: • Application • Horsepower & RPM • Gearbox (Reducer) Ratio • Output Speed • All Shaft Sizes • Overhang Load • Lever Arm (Distance from end of Gearbox output Shaft to Center-Line of Gearbox or Center Line of Gravity) B. Calculate Application Torque: C. Calculate Design Torque by applying 2.0 Service Factor to application torque. 2.0 x T (in-lb) = Design Torque D. elect coupling with a torque capacity equal to or greater than the Design Torque from S the Performance Data table. E. erify that the Bore capacity of the coupling will...
