20CrMnTi High Precision Spiral Bevel Gears for Transmission Part

Spiral bevel gear is a high-precision bevel gear that realizes 90° staggered axis transmission with arc spiral tooth traces. Compared with straight bevel gears, it features smoother transmission, higher load capacity and lower noise. Widely used in reducers, differentials, steering mechanisms, machine tools, agricultural machinery, construction machinery, etc., it achieves vertical power transmission, speed reduction and torque increase, serving as a core component of high-end transmission systems.

Product Features

• Spiral tooth surface meshing with high contact ratio, smooth transmission and low impact.
• 90° orthogonal drive, compact structure and flexible layout.
• High load capacity, suitable for heavy-duty, high-speed and continuous operation.
• Low noise, low vibration and high transmission accuracy.
• Available in left-hand, right-hand and customizable shaft angles.
• Hardened tooth surface with good wear resistance and long service life.
• Compatible with Klingelnberg, Gleason and other tooth standards.
