China OEM Wheel Hub Unit Manufacturers - Overrunning AlternatorPulley F-564313 – RNA

Our newly designed, manufactured and patented one-way pulley product improves the traditional transmission structure and designs a new transmission system with precise structure and excellent performance, avoids the negative electricity formed during reverse rotation, and reduces noise due to vibration absorbed by elastic parts. According to the positive impact on the performance of accessory drive system (depending on specific application), the advantages of OAP one-way pulley are as follows:

1. Unidirectional transmission capacity, bounce and reversal at the moment of startup do not produce transmission power;
3. Reduce belt vibration and tensioner stroke, and effectively reduce belt tension vibration during operation;
3. Increase the average speed of the generator in the engine idle phase; reduce the engine fuel consumption by about 10%.

At present, OAP produced by ina in Germany or NTN, NSK and Koyo in Japan has similar advantages over one-way pulley, which is also the performance of two-way (shock absorption) pulley.

If the flywheel works properly, the shaft will rotate freely in one direction and lock in the other. Depending on the manufacturer, the resistance in the locking direction may increase.

If the above results are not achieved, the alternator freewheel clutch must be replaced.

Maintenance instructions

Whenever any maintenance work is carried out on the unit drive, the override alternator pulley must always be tested.
