How to solve the early pitting condition of the reducer. Pitting corrosion must be related to the lubricant, and it is also closely related to the material of the reducer. There will be some processing specifications in the normal use process. Another point 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. Contact one end, even diagonally. Let's elaborate below.
First, the impact of materials and handling specifications
The selection of gear materials is correct or not, the matching of the load, and the selection and matching of heat treatment hardness are also the reasons that affect the early pitting.
Second, the impact of lubricants
The irrational lubrication of the gear transmission and the unsuitable choice of lubricant are also the reasons that affect the early pitting. Ways to prevent early pitting of the reducer gear:
(1) Reasonable lubrication of gear reducer transmission and selection of appropriate lubricant.
(2) Improve the precision of gear installation of the reducer and ensure the precision of gear contact.
As for the central drive reducer, if there is no good investigation during assembly and installation, there may be asynchronism between the left and right transmissions, and the load sharing effect is poor. In this case, the transmission gear on one side may not bear Load, and the other side of the transmission gear is overloaded (maximum 2 times the design load), which can easily cause progressive early pitting on the tooth surface.
