How to Solve the Early Pitting Issue in Reducers?
Point蚀 is related to lubricants and has a close connection with the material of the gear reducer. There are certain handling standards during regular use. Additionally, it is caused by poor gear contact, leading to localized overloading. This localized overloading causes the actual contact stress to far exceed the allowable contact stress of the gear material, with some gears not achieving full tooth length contact or only contacting at one end of the tooth, even diagonally.
The impact of material selection and processing standards: The correctness of gear material choice and the matching of load usage, as well as the selection and matching of heat treatment hardness, are also factors contributing to early pitting.
Lubricant Impact: Improper lubrication of gear drives and inappropriate lubricant selection are also contributing factors to early pitting. Methods to prevent early pitting in reducer gears:
Proper lubrication of gear reducers and selecting the appropriate lubricant.
(II) Enhance the installation accuracy of reducer gears to ensure proper gear contact precision.
For center-driven reducers, if not properly investigated during assembly and installation, there may be a lack of synchronization between the two transmission paths, resulting in poor load distribution. In such cases, one transmission gear may not bear the load, while the other may be overloaded (up to twice the design load), which easily leads to progressive early pitting on the gear surface.
