Mounting and Coupling

Application example

Two Internal Freewheels FD 40 CFR of standard type with bearing support as overrunning c lutches in the drive of the transport rollers in a p ackaging distribution unit. In normal opera tion, the transport rollers are driven by means of the freewheels that are working in driving operation. At the withdrawal station, the arriving packages can easily slip off as the drive is overrun by the freewheel (freewheeling oper ation).

Mounting
Internal freewheels FD in type standard and type with P-grinding are without bearing support. Concentric alignment of inner and outer ring must be provided by the customer. The per- missible 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 specified 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 D must be ISO P6. Please note the technical points on page 118 regarding the sprag track (shaft). The permissible operating temperature of the freewheel is - 40°C to 80°C.

Lubrication
An oil lubrication of the specified quality must be provided.
