Technical Description: Bonfiglioli W 63 U 10 P80 B5 B3
The Bonfiglioli W 63 U 10 P80 B5 B3 is a premium worm gear reducer from the «Universal» W series. The W series is the advanced evolution of the VF line, offering higher torque density and a more modular housing design. The W 63 frame is a robust industrial solution designed for continuous duty in packaging, textile machinery, and general automation where high efficiency and reliability are non-negotiable.
Advanced Engineering and Design
Featuring a 10:1 gear ratio, this unit is designed for high-speed output and high mechanical efficiency. The «U» (Universal) designation means the housing is finished on all sides, allowing for flexible mounting. Coupled with a P80 B5 flange, it is ready for integration with 0.75kW or 1.1kW IEC motors. The internal geometry is optimized to reduce friction, resulting in cooler operation even under high-load cycles.
Key Characteristics
- Part Number: W 63 U 10 P80 B5 B3.
- Series: W Series (Universal Worm).
- Gear Ratio (i): 10:1.
- Input Interface: P80 B5 (IEC).
- Mounting Position: B3 (Horizontal).
- Shaft Type: Hollow output shaft.
- Housing: High-grade alloy with optimized cooling fins.
Performance and Reliability
The W 63 series benefits from Bonfiglioli’s expertise in material science, utilizing a case-hardened worm shaft and a high-performance bronze alloy gear. The 10:1 ratio is particularly efficient for a worm gearbox, offering approximately 85-90% mechanical efficiency. The use of premium oversized bearings allows the unit to handle significant overhung loads on the output shaft, making it ideal for belt-driven applications.
