The generator's one-way belt pulley is an essential component, primarily consisting of the following parts:

The belt pulley housing: Typically made of high-quality metal materials such as cast iron or aluminum alloy to ensure its strength and durability. The center of the belt pulley housing usually features mounting holes for easy fixation onto the generator shaft.

2. Belt Groove: The outer circumference of the belt pulley is designed with grooves for installing and securing the belt. The shape and size of the belt grooves are determined by the type of belt used to ensure a firm fit on the belt pulley.

3. One-Way Clutch: This is a critical component of the generator's one-way belt pulley, allowing it to rotate in one direction while remaining stationary in the opposite direction. This design prevents the generator from reversing when the belt loosens or breaks, thereby protecting the generator from damage.

4. Bearings and bearing housings: Bearings are used to support belt pulleys, allowing them to rotate smoothly; while bearing housings are used to secure the bearings, ensuring their stability and durability.

5. Sealing Devices: To prevent dust and debris from entering the interior of the belt pulley, sealing devices such as dust covers or gaskets are typically designed.

In summary, the generator's one-way belt pulley is composed of multiple precise components, each playing a crucial role in ensuring the smooth operation of the generator.
