Overrunning Clutches for Textile Processing Equipment
A textile manufacturer required an overrunning clutch for use on equipment being installed for a new production line. The overrunning clutches allow the feed drive to power the rollers at a low speed (5 RPM) when threading the leading edge of a new roll of fabric. When the fabric is fully threaded and ready to be pulled at production speeds, the unit un-clutches the feed drive allowing those same rollers to be rotated at faster speeds (10 RPM) without back driving the lower speed feed drive. The clutch automatically disconnects the lower speed feed drive during higher speed operation and prevents possible damage to the feed drive if back driven at the higher speeds.
FSO overrunning, ball bearing clutches were selected for use on multiple drives on the textile production line. Units are oil lubricated and equipped with lip type seals and feature PCE sprags with and "Free-action" retainers. Model FSO 600 clutches were supplied with a torque capacity of 2,250 lb.ft. (3060 Nm).
FSO Overunning Clutches for Multi-Speed Warehouse Conveyor System
A large packaging operation was experiencing damage to the bottom of cartons on their case packing lines. The damage occurred as the cartons transferred from one conveyor to another conveyor which was moving at a 10 percent slower speed. Productivity was also impacted since the first two rollers of the slower conveyors needed to be replaced every year due to excessive wear. The cost of the rollers and the downtime associated with their replacement needed to be eliminated.
To correct the problem, FSO clutches were installed on the multi-speed conveyors that drive in only one direction to provide the non-destructive accommodation of the speed differential in the powered roller drive systems. The FSO clutches allow the slower speed zone to over-speed during the transitional period without back driving the slower drive system. Model FSO 500 clutches were supplied with a torque capacity of 1,175 lb.ft. (1621 Nm).
