FXM Sprag Overrunning Clutch

FXM Sprag Overrunning Clutch

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.

Technical Datas

Dimensions and Capacities

Notes:

The maximum transmissible torque is 2 times the specified nominal torque.

The theoretical nominal torque applies only for ideal concentricity between the inner and outer ring. In practice, the concentricity is affected by the bearing play and centering errors of the neigh bouring parts.

Then the nominal torques specified in the table apply, whilst taking into consideration the existing run out (T.I.R.).Higher speeds upon request.

Mounting

Integrated Freewheels FXM are without bearing support. Concentric alignment of inner and

outer ring must be provided by the customer. The permissible run out (T.I.R.) must be ob -

served.The Integrated Freewheel FXM is centered via the outer track F on the customer attachment part and bolted to this (refer to figure 67-1). The tolerance of the pilot diameter of the attachment part must be ISO h6 or h7.

The tolerance of the shaft must be ISO h6 or j6. For fitting to shaft ends, end covers can be supplied upon request (refer to figure 67-3).

Lubrication

At speeds in excess of the sprag lift-off speed, no special lubrication is required; the freewheel

functions maintenance-free. When operating below the sprag lift-off speed, an oil lubrication of the specified oil quality must be provided.
