What are the unique features of the ” overrunning generator pulley (OAP) with clutch” ?
Yuhuan Jingxiu Machinery Co., Ltd (is “GXOAP”) has more than 15 years of professional experience in the field of mechanical product research and generator pulleys, and we can provide you with the answer.
The working principle of the over-alternator pulley (OAP) is that when the alternator synchronizes the car to start and stop, it will generate huge torque and transmit it to the pulley. The clutch in the pulley starts to separate and absorb torsional vibration at the same time, thereby significantly reducing vibration and noise.
Beyond the Alternator Pulley (OAP)
There is a one-way clutch mechanism inside the overrunning alternator pulley that allows the belt to turn the alternator in one direction. When the engine suddenly slows down, the clutch allows the alternator to turn freely and spin at its own speed. A good OAP pulley should lock and turn the alternator rotor when rotating one way, but release and turn freely when rotating in the opposite direction. If the internal clutch mechanism fails, the pulley may slip, preventing it from driving the alternator, or it may remain locked, adding noise, vibration and stress to the belt drive system.
