Information
1. Material, hardness and defects. The material of the gear does not meet the requirements; it affects the contact fatigue of the gear
The main factor of strength is that the hardness after heat treatment is low, and the contact fatigue due to the gear cannot be guaranteed.
strength. In addition, defects on the tooth surface or inside are also one of the reasons for insufficient contact fatigue strength.
2. The gear accuracy is poor. Gear machining and assembly accuracy does not meet the requirements, such as meshing accuracy, motion
Poor accuracy, etc. There is also too much error in the center distance of the housing of the arc gear.
3. The lubricating oil does not meet the requirements. The grade of lubricating oil used is wrong, the viscosity of the oil is low, and the lubricating oil
Slippery performance is poor.
4. The oil level is too high. If the oil level is too high, the temperature of the oil increases, which reduces the viscosity of the lubricating oil and destroys the lubricating oil.
slippery performance, reducing the working thickness of the oil film.
