How to reduce the quenching cracking and deformation of heavy truck gear wholesale products?

First of all, it is necessary to correctly select the material of the heavy truck gear wholesale and rationally design the tooth shape. For the complex shape of the heavy truck gear wholesale should choose the gear steel with higher hardenability, so that it can be cooled in the slow quenching medium to reduce the internal stress. For heavy truck gear wholesale with higher precision requirements, bottom deformation steel can be selected and graded or isothermal quenching can be used. In the wholesale design of heavy truck gear, the cross-section thickness is reduced to avoid thin edge sharp Angle; Smooth transition at the junction of gear thickness as much as possible, for large gears, it is appropriate to use separate insert structure to create as much as possible after heat treatment can still be machined deformation conditions.
