Internal Freewheels Sprag Bearing

 FXN31-17/60 Internal Freewheels 1 Way Sprag Backstop Clutch

Feature

  Internal Freewheels FXN are sprag freewheels without bearing support and with sprag lift-off X. The sprag lift-off X ensures a wear-free free - wheeling operation when the inner ring rotates at high speed. The outer ring is pressed into the customer hous ing. This makes compact, space-saving fitting solutions possible. The freewheels FXN are used as:

Backstops

Overrunning Clutches

  for applications with high speed freewheeling operation and when used as an overrunning clutch with low speed driving operation. Nominal torques up to 20 500 Nm. The torque is transmitted on the outer ring by press fit. Bores up to 130 mm. Many standard bores are available.

 

Dimension and Capacity

The maximum transmissible torque is 2 times the specified nominal torque. See page 14 for determination of selection 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 Example

FXN31-17/60 Internal Freewheels 1 Way Sprag Backstop Clutch 2

Internal Freewheel FXN 38 - 17/70 NX as a backstop, arranged in a housing adapter to attach to an electric motor. The thin outer ring that is pressed into the housing enables a space-efficient fitting solution. Due to the high shaft speeds in normal operation (freewheeling o peration), the sprag lift-off X ensures a contactless and hence wear-free continuous oper ation.

FXN31-17/60 Internal Freewheels 1 Way Sprag Backstop Clutch 3

Internal Freewheel FXN 66 - 25/100 NX as an overrunning clutch in the creep drive of a textile machine. The freewheel installation is compactly solved by means of the thin outer ring that is pressed into the worm wheel. During setup, the machine is driven by the worm gear and the freewheel that is working in driving operation. In normal operation (freewheeling oper ation), the inner ring that is located on the high speed main drive shaft overruns and automatically disengages the creep drive. With the high overrunning speed of the inner ring, the type with sprag lift-off X is used; the sprags work in freewheeling operation without contact and hence are wear-free.

FXN31-17/60 Internal Freewheels 1 Way Sprag Backstop Clutch 4

  Internal Freewheel FXN 85 - 40/140 MX as a backstop fitted to the end of the first inter mediate shaft of a spur gearbox in the drive of an inclined conveyor belt. In the case of a motor stop the conveyor belt must be held securely so that the conveyor goods do not pull the belt backwards and possibly cause serious damage. Due to the high shaft speeds in normal oper ation (free wheeling operation), the sprag lift-off X ensures a contactless and hence wear-free c ontinuo us operation.

 

  Internal Freewheels FXN 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 observed. The torque is transmitted on the outer ring by press fit. In order to transmit the torques speci- fied in the table, the outer ring must be accommodated in a housing with an external diameter K. The housing is made of steel or grey cast iron in minimum quality GG-20. When using other housing materials or smaller external diameters, we urge you to contact us regarding the transmissible torque. The tolerance of the housing bore is specified in the table under dimension D. The tolerance of the shaft must be ISO h6 or j6.

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 quality must be provided.
Example for ordering
Freewheel size FXN 61 - 19/95, type with sprag
lift-off X and 35 mm bore:
• FXN 61-19/95 NX, d = 35 mm
