磨齿烧伤和裂纹及其变质层深度

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

磨齿烧伤和裂纹是影响齿轮质量的关键．通过对磨削烧伤的种类和原因进行了较为 详细的分析，针对锥面砂轮磨齿机磨齿特点，找出影响变质层深度的主要因素．采用回归设计 方法，通过试验找出齿面变质层深度与各工艺参数间的关系式．这对于分析磨削烧伤等磨削缺 陷是有意义的．

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 fac-tors of affecting the depth of the thermal damage layer were found. By means of regression design, the rela-tional 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.
