1. Product Overview
Bevel Gears are mechanical components designed to transmit motion and torque between intersecting shafts (typically at 90° angles), with teeth formed on conical surfaces. They are categorized by tooth geometry, manufacturing methods, and application scenarios, offering solutions for diverse industrial needs.

3. Technical Highlights
-
Precision Manufacturing
- Utilize Gleason/Klingelnberg machines for helical/spiral tooth shaping, achieving ISO 6-8 precision (tooth error ≤0.02mm).
- Surface treatments: Quenching (HRC 58-62), nitriding (HV 900+), or anodizing for corrosion resistance.
-
Performance Advantages
- Low Noise: Spiral/zerol teeth reduce vibration by 10-15% compared to straight teeth.
- High Efficiency: Helical designs achieve ≥98% transmission efficiency in high-speed systems.
- Self-Locking: Worm bevel gears with ratios >10:1 prevent reverse rotation.
