Research of Grinding Teeth Burn and Crack and Thier Thermal Damage Layer
-
摘要: 磨齒燒傷和裂紋是影響齒輪質量的關鍵.通過對磨削燒傷的種類和原因進行了較為詳細的分析,針對錐面砂輪磨齒機磨齒特點,找出影響變質層深度的主要因素.采用回歸設計方法,通過試驗找出齒面變質層深度與各工藝參數間的關系式.這對于分析磨削燒傷等磨削缺陷是有意義的.Abstract: 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.
