In order to install the OAP to the extension of the generator shaft, there is a hole in the center of the belt hub with a thread and a keyway at the front end. They are used to ensure the tightening torque (maximum 85ncm). Therefore, no additional fastening elements are required

The axial force generated by the belt is absorbed by the bearing assembly; Therefore, the maximum axial clearance of 0.6mm ensures that the belt track can be adjusted freely

The lip seal ring on the motor side and the protective cover at the front end can prevent the weakening of OAP function caused by dirt and splash under working conditions. The protective cover is clamped after OAP is installed on the motor shaft. It can be seen that the outer surface of OAP is coated with a layer of anti rust layer; All other metal surfaces are uncoated

This modular design can effectively shorten the sample delivery time and the start time of mass production. Of course, it can reduce the product cost.

Why does the overrunning alternative pulley / one way clutch pulley replace the traditional two-way pulley? It is because the overrunning alternative pulley has the advantages that the traditional two-way pulley does not have.
