1. The influence of the manufacturing and assembly accuracy of the reducer
One of the reasons for the early pitting of the planetary reducer is that due to the low assembly accuracy, the gear contact area is reduced and the local overload causes the actual contact stress to exceed the allowable contact stress of the gear material. This is because the two centerlines of the gear pair It is caused by excessive non-parallel or cross deviation and excessive tooth alignment error during gear machining.
The improper selection of gear material and heat treatment hardness results in low tooth surface hardness, which cannot meet the processing requirements, and is also an important cause of pitting corrosion.
2. The influence of installation accuracy
Since the shaft alignment of the planetary reducer and the motor after installation does not meet the requirements of the specification, the motor coupling and the reducer input end coupling are not concentric, resulting in uneven force on the input end gear of the reducer, and the transmission gear on one side is overloaded. The force will cause pitting corrosion on the tooth surface, resulting in damage and failure of the gear of the reducer.
3. The influence of lubricating oil
Lubricating oil can reduce wear in mechanical transmission, shock absorption, lubrication, and increase the life expectancy of equipment.Therefore, in the daily gear maintenance, creating good lubrication conditions, adopting reasonable lubrication technology, reducing and reducing the pitting and wear of the gear tooth surface is a topic that the field technicians of the planetary reducer must pay attention to.
