How to deal with the early pitting of the reducer?

How to deal with the early pitting corrosion of the reducer. The pitting corrosion of the reducer must be related to the lubricating oil. At the same time, it is also closely related to the materials of the reducer. The daily use process has corresponding treatment standards. The second is due to the local overload caused by poor gear contact. The local overload of the gear makes the actual contact stress greatly exceed the allowable contact stress of the gear material. Some gears can not reach the full tooth length contact, or only contact at one end of the tooth, or even diagonal contact. The following is a comprehensive exposition by Xiaobian.
1、 Influence of lubricating oil
The unreasonable lubrication of gear transmission and the improper selection of lubricant are also the reasons affecting the early pitting corrosion of reducer. Ways to prevent early pitting corrosion of reducer gear:
(1) Reasonable lubrication of gear reducer transmission and selection of appropriate lubricant.
(2) Improve the gear installation accuracy of the reducer and ensure the contact accuracy of the gear.
For the center drive reducer, without proper investigation during assembly and installation, there may be asynchrony between the left and right transmission and poor load sharing effect. In this case, the transmission gear on one side may not be able to bear the load, while the transmission gear on the other side is overloaded (* * * up to twice the design load), which is easy to produce progressive early pitting corrosion.
2、 Impact of materials and management specifications
The correct selection of gear material, the matching of service load and the selection and matching of heat treatment hardness are also the reasons affecting the early pitting corrosion.
For the center drive reducer, if it is not well investigated during assembly and installation, there may be asynchrony between the left and right transmission and poor load sharing effect. In this case, the transmission gear on one side may not bear the load, while the transmission gear on the other side may be overloaded (* * * up to twice the design load), It is easy to cause progressive pitting on the tooth surface at the early stage of the reducer.
