How to solve the condition of early pitting corrosion of reducer.Pitting must be related to the lubricating oil, and it is also closely related to the material of the reducer.There will be certain handling specifications in the usual use process.Another point is that the partial overload of the gear is caused by the poor contact of the gear. The partial overload of the gear makes the actual contact stress greatly exceed the allowable contact stress of the gear material. Some gears cannot reach the full tooth length contact or only in the tooth contact at one end, even diagonally.The following is a detailed explanation of Shanghai Jinchuan reducer.
XNUMX. The influence of materials and handling specifications
Whether the gear material is selected correctly or not, the matching condition of the use load, and the selection and matching of the heat treatment hardness are also the reasons that affect the early pitting corrosion.
Second, the impact of lubricating oil
Unreasonable lubrication of gear transmission and unsuitable selection of lubricants are also the reasons for early pitting corrosion.Ways to prevent early pitting of reducer gears:
(XNUMX) Reasonable lubrication of gear reducer transmission and selection of suitable lubricants.
(XNUMX) Improve the gear installation accuracy of the reducer and ensure the gear contact accuracy.
For the center drive reducer, if it has not been well investigated during assembly and installation, there may be asynchrony between the left and right transmissions, and the load sharing effect is poor. In this case, one side of the transmission gear may not be able to bear it. The gear on the other side is overloaded (up to 2 times the design load), which can easily cause progressive early pitting on the tooth surface.
