How to solve the problem of early corrosion of reducer.Pitting must be related to lubricating oil and moderator materials.A normal course of use will have certain process specifications.Another problem is localized overloading caused by gear contact.The local overload device makes the actual contact stress greatly exceed the allowable contact stress of the gear material.Some gears do not reach the full tooth length and only touch or touch one end of the teeth, or even diagonally.
1. Influence of material and processing specifications
The correct selection of gear materials, the matching of service loads and the selection and matching of heat treatment hardness are also the reasons that affect early pitting corrosion.
2. The influence of lubricating oil
Unreasonable lubrication of gear transmission and improper selection of lubricant are also the reasons affecting early pitting corrosion. Methods to prevent early pitting corrosion of reducer gears:
(1) Reasonably lubricate the transmission of the reducer and choose the appropriate lubricant.
(2) Improve the gear installation accuracy of the reduction gear to ensure the contact accuracy of the gears.
If the central transmission reducer is not well investigated, assembled and installed, there may be two asynchronous transmission modes, and the unified load effect is poor.In this case, one side of the transmission gear should not bear the load, and the transmission gear on the other side is overloaded (this can meet twice the design load), which can easily lead to advanced early pitting on the tooth surface corrosion.
