China OEM Overrun Pulley Factories - Generator CLUTCH PULLEY F-567525 – RNA

In order to prevent slipping in the belt drive system of the generator, the selection of one-way clutch pulley with appropriate function and good quality has a great impact on the power generation function of the generator and the service life of the belt, reducing vibration and reducing oil consumption. What torque force must be borne by the pulley when matching the generator and what is the slip force distance when exceeding? The basic factors to be considered are as follows:

1. Rotating torque / rated torque of generator;
2. Operating speed range and inertia of driven parts;
3. Exceed the range of operating speed;
4. Service times, service life, etc.

OAP one-way belt pulley is composed of a wheel pan, roller clutch and belt hub (see the figure below). The outer contour of the wheel pan is designed to be suitable for matching with multi wedge belt. There are a row of needle rollers on both sides of the roller clutch to support radial load

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
