AI Technical Summary
In the existing gear heat treatment process, gears are prone to thermal stress deformation due to uneven temperature. Existing anti-deformation structures are complicated to operate, costly, and difficult to effectively prevent deformation between teeth and in the central hole.
A gear anti-deformation tooling was designed, including a positioning seat, a guide shaft, and an anti-deformation component. The anti-deformation component consists of a first anti-deformation component and a second anti-deformation component, which are located in the tooth groove and the center hole, respectively. The tooth groove and the center hole are prevented from deforming by the cooperation of the conical and cylindrical structures.
It effectively prevents deformation of the tooth groove and center hole during gear heat treatment. It has a simple structure, low cost, and is easy to install and maintain, thus reducing production costs.
