V-Belt Pulley Components


The sheave is the grooved wheel that guides the belt and transmits power. Its design and material affect the overall efficiency and lifespan of the pulley system.


The bore is the central hole of the pulley, which fits onto the shaft. Precise bore dimensions are essential for proper fit and alignment.


The keyway is a slot that accommodates a key, ensuring the pulley remains fixed to the shaft. This component is critical for preventing slippage and maintaining alignment.


Flanges are the raised edges on the sides of the pulley that help retain the belt in position. They prevent the belt from slipping off during operation.

Selecting or Customizing the Right Belt Pulley

Load Requirements

Understanding the load requirements is crucial for selecting the appropriate belt pulley. This includes analyzing the power transmission needs and the operational conditions.

Material Considerations

Choosing the right material for the belt pulley depends on factors such as durability, weight, and environmental conditions. Common materials include steel, aluminum, and composites.

Size and Dimensions

Accurate measurements of the pulley¡¯s size and dimensions, including diameter and width, are essential for ensuring compatibility with the belt and the overall system.

Speed and Efficiency

The desired speed and efficiency of the system play a significant role in pulley selection. Calculating the required speed ratios helps in choosing the right pulley design.

Maintenance Needs

Consideration of maintenance needs, such as ease of replacement and durability, impacts the long-term performance of the belt pulley system. Selecting pulleys with lower maintenance requirements can reduce operational costs.
