FARR Coupling

The FARR Coupling is used whenever a rigid connection is required amongst the lower velocity shaft of the gearbox and the head shaft of the conveyor, bucket elevator, mixer or any over-hung or suspended load. When sized correctly, the FARR Coupling will carry the applica-tion torque, fat of gearbox, motor and swing plate. From the situation of the mixer, it can carry the bodyweight of your shaft and impeller, thrust forces and resulting bending moments.
Components of the FARR Coupling include male and female piloted hubs produced from 4140 alloy steel. The hubs are extended to assure 80% hub to shaft get in touch with. Keeper plates are incorporated for safety. The two hubs are assembled with Grade eight bolts and Grade À Prevailing Torque nuts. Regular coupling sizes possess a nominal torque range from 11,300 to five,736,000 in-lbs. Greater sizes can be found dependant upon the application.

B.Calculate Application Torque:
T (in-lb) = ¡ê¡§HP x 63025¡ê?/RPM
C.Calculate Design and style Torque by applying 2.0 Service Factor to application torque.
D.Select coupling with a torque capability equal to or greater than the Design and style Torque from the Performance Data table.
E.Verify that the Bore capacity in the coupling will meet the application shaft requirements.
F.The Male pilot hub to always be applied on the Reducer (Gearbox or Driver) shaft along with the Female pilot hub to always be employed around the Head (Driven) shaft.
G.Drive System Analysis must be performed by Application Engineering to verify coupling assortment.
