V-Belt Pulley

Understanding V-Belt Pulleys

V-Belt Pulleys (also known as sheaves) are essential components in V-belt drive systems, used to transmit power between shafts. They feature V-shaped grooves designed to match the cross-section of the V-belt. As the belt seats into the groove, the wedging action provides a strong grip, allowing for high torque transmission and reducing slippage compared to flat belts.

Key Aspects:

• Working Principle: Relies on the friction generated by the wedging action of the belt sides against the pulley groove walls.
• Belt Sections: Pulleys are designed for specific V-belt cross-sections (e.g., Classical V: A, B, C, D; Wedge: SPZ, SPA, SPB, SPC, 3V, 5V, 8V). Using the correct pulley for the belt section is critical.
• Number of Grooves: Pulleys are available with single or multiple grooves to accommodate multiple belts for higher power transmission requirements.
• Material: Cast Iron is the most common material due to its durability, machinability, and cost-effectiveness. Aluminium is used for lighter weight, and Steel for higher strength/shock load applications.
• Bore Type: Pilot bore pulleys require custom boring and keyway cutting. Taper Lock bush compatible pulleys allow for quick installation and easy shaft size changes using standard bushings.

Advantages:

• Efficient power transmission.
• Cost-effective drive solution.
• Simple installation and maintenance.
• Wide range of standard sizes available.
• Absorbs some shock load and vibration.
