How to solve the situation of early pitting of the gearbox. Pitting is definitely related to lubricants, and it is also closely related to the material of the gearbox. The usual use of the process will have a certain processing specifications. There is also a point is due to the gear contact is not good caused by local overload, the local overload of the gear so that the actual contact stress greatly exceeds the gear material’s expected contact stress, some gears can not reach full-tooth long contact or only contact at one end of the tooth, or even verb contact. Here’s a look at the GearKo gearbox for us.
First, the impact of materials and treatment specifications
The selection of gear material is correct and the use of load matching, heat treatment hardness selection and matching, but also affect the early pitting reasons.
Second, the impact of lubricants
Unreasonable lubrication of gear transmission and discomfort in lubricant selection are also the causes of early pitting. Ways to prevent early pitting of gears in the gear of the gear:
(1) Reasonable lubrication of gear reducer transmission and selection of suitable lubricants.
(2) Improve the accuracy of gear installation of the gear reducer and ensure the contact accuracy of the gear.
For the central drive gearbox, if the assembly and installation, without a good investigation, there may be left and right two transmission of different steps, poor load effect, in this case, one side of the transmission gear may not bear the load, and the other side of the transmission gear is overloaded (larger up to 2 times the design load), which can easily cause the flanks to produce early progression pitting.
