• Cogged V-Belts: These belts have notches or cogs on the inner surface, which allow for higher power transmission capacity and improved flexibility.
• Variable Speed V-Belts: These belts are designed to operate efficiently at varying speeds and provide a wide range of speed ratios.
• Synchronous Belts: These belts have teeth that mesh with corresponding grooves in the pulley, providing precise power transmission and eliminating slippage.

Each belt type has specific design characteristics, and V pulleys are manufactured to match the corresponding belt type for optimal performance.

4. Tensioning:

V pulleys are designed to work in conjunction with belt tensioning mechanisms to maintain the required tension in the belt. Tensioning devices such as idler pulleys or tensioners are used to adjust the tension and ensure proper belt engagement with the pulley.

5. Speed Ratio:

The pulley diameter ratio determines the speed ratio between the driving and driven pulleys in a belt drive system. By selecting pulleys of different diameters, different speed ratios can be achieved to suit the specific application requirements.

6. Compatibility:

It is essential to ensure compatibility between the V pulleys and the belts used in the system. This includes considering factors such as the pulley groove profile, belt width, belt type, and speed requirements. Manufacturers provide specifications and guidelines to help users select the appropriate pulleys for their specific belt types and sizes.

By considering these factors, V pulleys can effectively handle different belt types and sizes, providing reliable power transmission in various applications.
