Overrunning clutch
A free wheel used as overrunning clutch
disengages automatically when the driven part rotates faster than the
driving part.
Roller type free wheels, when used for overrunning clutch
applications must be positioned in such a way that, in the overspeed
range, the internal free wheel component is stationary or rotates slowly
and the external component overspeeds. This layout ensures a higher number
of overspeed rotations, reduces wear and overheating and increases the
life of the overrunning clutch free wheel.
