Research of Grinding Teeth Burn and Crack and Thier Thermal Damage Layer

Grinding teeth burn and crack is the key problem that affects the quality of a gear. The sort and reason of grinding burn were analyzed. Based on the characteristic of the coned shape grinding wheel, the factors of affecting the depth of the thermal damage layer were found. By means of regression design, the relational formula between the depth of the thermal damage layer and parameters of technology was found. It is very useful to analyze the errors such as burn, crack and so on.
