What is the cause of fatigue pitting of the reducer?
Fatigue pitting corrosion of reducer is a common fault of reducer. Fatigue pitting corrosion starts with a small and shallow diameter, and most of them occur in the pitch circle and the place below the pitch circle. After fatigue pitting occurs, the development speed is quite fast and slows down. The machine can no longer be used.

The causes of fatigue pitting of the reducer are as follows:

1. Lubricating oil expires or deteriorates, the viscosity is too low or fails, so that an oil film cannot be formed between the tooth surfaces of the gears. As a result, the direct contact between the teeth causes fatigue pitting on the tooth surfaces.

2. During the installation process of the reducer gear, the maintenance process is not strictly carried out, resulting in poor installation, causing partial contact of the tooth surface, and excessive load causing fatigue and pitting of the tooth surface.

3. The use of the transmission bearing of the reducer exceeds the limit or the clearance between the bearing and the bearing seat hole is too large, which causes the transmission bearing to vibrate too much and cause the load to increase.

During the use of the reducer, due to the passage of time, it may affect the equipment, and some failures will gradually occur. When we all use the reducer, we must pay attention to the usual maintenance and lubrication work, pay attention to the service life of the lubricating oil, and pay attention to adding it in time.
