Application example
Complete Freewheels FRS 600 in both drive units of a transport system with a conveyor belt that moves both forward and backward (reversible operation). In order to ensure that the conveyor belt is moved under tension, forward movement is driven by drive unit I, reverse movement by drive unit II. The reewheels automatically disengage the respective non working drive, eliminating the need for expensive external clutches or brakes. For forward movement, drive unit II is started in freewheeling direction of freewheel II; free-wheel II is in freewheeling operation and disengages drive unit II from the conveyor belt. Afterwords drive unit I is started in the locking direction of the freewheel I; freewheel I is in driving operation and the conveyor belt is moved forward by drive unit I. The speed of drive unit I is lower than that of drive unit II. Thus freewheel remains in freewheeling operation and drive unit II is not improperly engaged.
For reverse movement, the drive units are started in reverse order and direction of rotation
at the corresponding speeds.
 
Mounting
The customer attachment part is centered on the external diameter D and then bolted on to
the face. The tolerance of the shaft must be + 0 / - 0,001 inch and the tolerance of the pilot diameter D of the attachment part must be - 0 / + 0,002 inch.
