Automobile and tractor gear processing requirements

The working conditions of automobile and tractor gears are relativelyMachine GearIt is cumbersome, and its processing requirements are described below for reference.

1. Compared with machine tool gears, it requires higher wear resistance, fatigue strength, core strength and impact toughness.

2. Generally, low-carbon alloy steel (20MnMoB, 20SiMnVB, 30CrMnTi, etc.) is generally used, and it is treated by carburizing, quenching, and low-temperature tempering, because of the medium load and large impact.

3. The transmission torque of the tractor's final drive gear is relatively large, the unit pressure of the tooth surface is relatively high, the sealing is not good, sand and lime soil are easy to penetrate, and the working conditions are relatively poor. 20CrNi3A etc. carburizing is often used.
