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 SPB Taper Bore Pulleys

1. High-Efficiency Power Transmission

   • 40° wedge angle increases belt contact area by 30% vs. SPA profiles

   • Achieves 98% transmission efficiency (ISO 4184 certified)

2. Superior Anti-Slip Performance

   • 12mm groove depth + 34° sidewall angle minimizes slippage (<1.5% at 2,000 RPM)

   • Stable lateral belt tracking under variable loads

3. Broad Shaft Compatibility

   • Adapts to Ø20-160mm shafts via interchangeable taper bushes (e.g., TB 3035 → TB 3560)

   • Single pulley covers multiple shaft sizes

4. Maintenance-Optimized Design

   • Keyless installation reduces disassembly time by 80% vs. solid-hub pulleys

   • Bolt-tightening only (no hydraulic tools/heating required)

5. High-Temperature Resilience

   • Cast iron (HT250) withstands 180°C; aluminum alloy handles 150°C

   • Ideal for HVAC/fan applications

6. Shock Load Tolerance

   • 50% higher instantaneous overload capacity vs. SPA pulleys

   • Damping effect from tapered bushing interface
