How to solve the early pitting corrosion of cycloid pin gear reducer. The pitting corrosion of cycloid pinwheel reducer must be related to lubricating oil, and it should also be closely related to the material of cycloid pinwheel reducer. The normal use process will have certain processing specifications. Another point is caused by 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.
1、 Impact of material and handling 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.
2、 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. Ways to prevent pitting corrosion of cycloidal pinwheel reducer:
1. Reasonable lubrication of gear reducer transmission and selection of appropriate lubricant.
2. Improve the installation accuracy of reducer gear and ensure the contact accuracy of gear.
For the center driven cycloid pin gear 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), This can easily cause progressive early pitting on the tooth surface.
