Description

Spiral Bevel Gear Set for Precision Right-Angle Transmission


The spiral bevel gear set is a high-precision mechanical transmission component designed to transfer motion and power between intersecting shafts, typically at a 90-degree angle.
With helical tooth geometry, these gears deliver smooth, quiet, and efficient power transmission — ideal for micro reducers, automation systems, and high-performance machinery.


1. Structure & Working Principle

This gear pair consists of:

  • Bevel Pinion (small gear) – connected to the input shaft, responsible for driving.

  • Bevel Gear (large gear) – mounted on the output shaft, transmitting motion at a right angle.

The spiral bevel design allows progressive tooth engagement, minimizing noise and vibration compared to straight bevel gears.
The teeth are precisely ground after heat treatment to ensure excellent contact accuracy, high load capacity, and long service life.

3. Manufacturing Process

  1. CNC Gear Cutting – Advanced Gleason or Klingelnberg gear-cutting centers ensure perfect spiral geometry.

  2. Heat Treatment – Carburized and quenched for surface hardness while maintaining core toughness.

  3. Gear Grinding – High-precision grinding achieves low noise and minimal backlash.

  4. Dynamic Balancing – Guarantees smooth operation at high speeds.

  5. Inspection & Testing – Every gear undergoes runout, tooth contact, and torque verification before delivery.
