Backstop clutch RSXM

Feature

The series RSXM completes teh small to medium backstop range, which commenced with the highly successful RSCI programme. Type RSXM is a centrifugal lift off sprag type freewheel with the inner race rotating. Only the inner race is designed for freewheeling. It is a non self-supported type.Bearings must be provided to ensure concentricity of the inner and outer races and support axial and radial loads, as shown overleaf. Concentricity and run-out limits must be observed.

The RSXM type accepts all types of lubricant currently used in power transmission equipment. It is possible to mount these freewheels directly in gear-boxes without seperate lubrication. An oil mist ist generally sufficient. Grease lubrication may be acceptable if the unit works mostly in overrunning condition, as on E-motors. When used as a backstop, it must be checked that the overrun-ning speed will not go below the minimum speed given in the characteristic table.

NOTES

1) T _max = 2 × T _KN

2) This maximum allowable torque transmission speed

n max must not be exceeded when transmitting torque.

3) This minimum allowable overrunning speed n imin

should not be rdeuced under continuous operation.

Possible reduction of this minimum speed in request.

4) Inner race overruns.
