Why the gear processing deformation

As we all know, it is very easy to appear deformation phenomenon in the process of gear processing.

Sometimes only from the heat treatment aspect to take measures to solve the gear deformation has certain difficulties, from the cold, hot processing of the whole process of various factors to consider, specific situation specific analysis, take corresponding measures to eliminate or weaken the influence of adverse factors, this is an effective way to reduce the gear heat treatment distortion.

The distortion of gear heat treatment is very complex, which is a comprehensive reflection of all the factors affecting the cold and thermal processing processes.

Residual stress generated by machining, thermal stress and tissue stress in the heat treatment process will have a certain impact on the deformation.

And they affect many factors, involving raw materials, workpiece structure shape design, the whole process, technical requirements, machining methods, processing conditions, heat treatment process (heating, cooling), tooling, etc.
