introduction

Reducer Backstop clutch FXM140-50SX

Integrated Freewheels FXM

for bolting to the face

with sprag lift-off X

 

Features

Integrated Freewheels FXM are sprag freewheels without bearing support and with sprag

lift-off X. The sprag lift-off X ensures a wear free freewheeling operation when the inner ring rotates at high speed. The freewheels FXM are used as:

 Backstops

 Overrunning Clutches

for applications with high speed freewheel ing operation and when used as an overrunning

clutch with low speed driving operation. Nominal torques up to 888 000 Nm. Bores up to 460 mm. Many standard bores are available.

 

Sprag lift-off X

Integrated Freewheels FXM are equipped with sprag lift-off X. The sprag lift-off X is used for backstops and overrunning clutches, provided that in freewheeling operation the inner ring is rotating at high speed and providing with overrunning clutches that the driving operation is conducted at low speed. In freewheeling operation, the centrifugal force FC causes the sprag to lift off from the outer track. In this operating state, the freewheel works wear-free, i.e. with unlimited service life.

 

Figure 64-2 shows a freewheel with sprag liftoff X in freewheeling operation. The sprags which are supported in a cage connected with the inner ring, rotate with the inner ring. Thecentrifugal force FC that is applied in the center of gravity S of the sprag turns the sprag counterclockwise and rests against the support ring of the cage. This results in the gap a between the sprag and the outer track; the freewheel works with out contact. If the inner ring speed decreases to such an extent that the effect of the centrifugal force on the sprag is less than that of the spring force FF , the sprag again rests on the outer ring and the freewheel is ready to lock. If used as an overrunning clutch, the driving speed must not exceed 40% of the lift-off speed.
