ABSTRACT:
A normally lubricated bearing, typically a ball bearing, serves to transmit torque from a drive shaft for the fan wheel of an alternator. The driving and driven bearing surfaces form the coupling parts respectively on the drive side and the delivery side of the coupling. A cup spring is useful to control the bearing friction that must be overcome at a limiting speed at which the drive shaft begins to turn faster than the driven device. Such couplings are useful for engine fans, pumps, or other similar auxilary devices in motor vehicles.
