Gear shafts

18CrNiMo7-6

H≤1.8ppm

• Hardness ≤ 250HB.

• Materials can be selected according to customer requirements.

• Spur gear shafts: Equipped with straight gear teeth, suitable for low-speed and high-torque transmission scenarios.

• Helical gear shafts: Featuring inclined gear teeth, they offer smoother transmission and lower noise compared to spur gear shafts, making them ideal for high-speed transmission systems.

• Bevel gear shafts: With conical gear teeth, they are mainly used to change the direction of power transmission (e.g., in the differential mechanism of automobiles).

In the manufacturing process, gear shafts typically require high-precision machining (such as turning, milling, grinding, and gear hobbing) to ensure the accuracy of gear teeth and the coaxiality of the shaft, thereby guaranteeing the efficiency and service life of the transmission system. Common materials for gear shafts include high-strength alloy steels (e.g., 40Cr, 20CrMnTi) and carbon steels, which can be further enhanced through heat treatment processes (such as quenching and tempering) to improve hardness, wear resistance, and fatigue strength.
