Product Description
Fr300ca Complete Freewheels with Sprags Used as Overrunning Clutchs

Features

for installation. The freewheels FRS are supplied oil-filled. The freewheels FRSG are supplied grease filled. The freewheels FRS and FRSG are used as:
Backstops
Overrunning Clutches
Indexing Freewheels

Maximum torques up to 55 000 lb-ft.
Bores up to 7 inch. Standard bores in inch dimension are available from stock. Metric
bores on request.
 
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 freewheels 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. After words 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 II 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.
