Product Description

Product Description

     The V-belt pulley with taper bush is a highly efficient and flexible mechanical drive component, comprising a V-belt pulley and a taper bush (also known as a taper lock bush). It secures the pulley to the drive shaft via the keyless connection method of the taper bush. This assembly is widely used in industrial drive systems for fans, pumps, compressors, conveying equipment, and similar applications.

           

Core Advantages of SPA V-Type Taper Bore Drive Pulleys

 

1. Precise Connection and Strong Stability
   The taper bore structure fits tightly with the shaft, eliminating radial and axial looseness during high-speed operation, significantly reducing vibration and noise, and ensuring stable operation of the transmission system. It is particularly suitable for medium-speed (10-25m/s) and medium-power (3-75kW) scenarios, minimizing power loss caused by installation deviations.
2. Convenient Installation and Maintenance
   Compared with keyway or interference-fit pulleys, the taper bore design, combined with a tapered sleeve, enables quick assembly and disassembly without complex tools. This significantly shortens equipment downtime for maintenance, making it especially suitable for scenarios requiring efficient operation and maintenance, such as automated production lines.
3. Excellent Transmission Efficiency and Adaptability
   The V-groove is optimized to fit SPA-type belts (13mm top width, 8mm height), resulting in low slippage and a transmission efficiency of 90%-95%. It is compatible with various shaft diameters (achieved by replacing the tapered sleeve) without the need for customized processing, offering wide adaptability.
4. Balanced Load Capacity and Operation
   With moderate dimensions, it has stronger load-bearing capacity than SPZ-type pulleys, capable of handling medium loads, while being lighter than SPB and SPC types. It operates with low vibration, making it suitable for equipment requiring high stability (such as precision textile machines and printing presses).
