As we all know, gear deformation is easy to occur in the process of machining.
Sometimes it is difficult to take measures to solve the deformation of gears only from the aspect of heat treatment. It is necessary to consider various factors in the whole process of cold and hot processing, analyze the specific situation, and take corresponding measures to eliminate or weaken the influence of adverse factors, which is an effective method to reduce the distortion of gears in heat treatment.
The distortion of gear heat treatment is very complex, which is a comprehensive reflection of all the influencing factors of cold and hot machining processes. Residual stress produced by machining, thermal stress and structural stress during heat treatment will have a certain impact on deformation. There are many influencing factors, including raw materials, workpiece structure and shape design, the whole process, technical requirements, machining methods, processing conditions, heat treatment processes (heating, cooling), tooling, etc.
