Design and use requirements for parts of hard tooth surface reducer

The gear in the hard tooth reducer is a relatively basic part of the entire equipment, mainly playing a transmission role. In order to ensure the efficient and stable operation of the equipment, the quality and hardness requirements for this part are relatively high. Below, the editor will explain the hardness requirements of hard tooth surface reducers to everyone.

1. High wear resistance and contact fatigue strength.

2. Good comprehensive mechanical properties to prevent impact or overload fracture.

3. High bending fatigue strength.

4. The center of the gear teeth should have sufficient strength and toughness.

5. The gears of hard gear reducers are mostly made of medium carbon steel (such as 45 steel) for quenching and tempering or normalizing treatment under conditions of medium load and low speed.

For shafts with higher requirements, alloy quenched and tempered steel (such as 40Cr) can be selected and subjected to quenching and tempering treatment.

When bearing heavy loads, high speeds, and large impacts, alloy carburized carbon steel (such as 20CrMnTi) should be selected for carburizing and quenching treatment.

When selecting materials for gears in hard gear reducers, a decision should be made based on comprehensive consideration of working conditions and technical requirements, in order to correctly select gears with suitable hardness and working conditions that meet the high-speed operation requirements of the entire equipment
