Formsprag Clutch Model FSO Overrunning Clutches for Auto Assembly Dual-Drive Conveyor
Formsprag clutches were selected for use on the conveyor system in a Midwestern
auto assembly plant. FSO overrunning clutches were mounted on the lead shaft of the
dual-drive conveyor system to provide instantaneous switching from the primary drive
to a stand-by drive in case either drive fails. This drive configuration ensures that the
assembly line keeps moving to maintain production schedules.
Mounting the clutches between each drive and the conveyor allows for automatic
clutching and de-clutching when switching from one drive to the other without any
utility, including air lines, or input to the clutch.
Formsprag FSO overrunning, ball-bearing clutches feature PCE sprags with
Formchrome® and Formsprag “Free-action” retainers. Model FSO 800 clutches were
supplied with a torque capacity of 7,000 lb.ft. (17940 Nm) to meet the requirements
of this application. Since the drives of this floor-mounted conveyor are located in tight
below-floor wells, a special low-temp grease lubricant was specified (in lieu of standard
oil lubricant) due to the limited service access.
Utilizing FSO clutches on this dual-drive application reduced installation and operating
costs by eliminating the need for controls or activation mechanisms.
