Application example
Internal Freewheel FCN 30 R as overrunning freewheel in the drive of the roof brush of an automatic car wash ing facility. The freewheel is arranged in the hub of a shaft coupling that
connects the motor and the reduction gear. The freewheel prevent the drive from pushing the
roof brush uncontrolled down onto the car roof in the event of a fault. The roof brush is raised
by the freewheels that are working in driving oper ation. The direction of motor rotation changes in order to lower the brush. The downwards movement of the roof brush is performed
by its own weight at the speed specified by the motor. In the case of an uncontrolled
lowering of the roof brush on the car roof, the drive is automatically disengaged via the
freewheel. The brush rests on the roof under its own weight, while the freewheel which is working in driving operation enables the drive to continue to turn in the lowering direction with -
out causing any damage.
 
Mounting
Internal freewheels FCN R are without bearing support. Concentric alignment of inner and
outer ring must be provided by the customer. 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 H7 or J6 and the tolerance of the shaft must be ISO h6 or j6.
 
Lubrication
An oil lubrication of the specified quality must be provided.
