摘要
剃齿是齿轮精加工的高效传统工艺,广泛应用于汽车、拖拉机和机床制造行业,但标准剃齿刀在剃齿时会产生齿形中凹,从而影响了齿轮齿形的加工精度和齿轮的传动质量(高噪声、低寿命).通过分析剃齿的加工过程,推导出了平衡剃齿的条件,即:剃齿过程中,剃齿齿面两侧在啮合线上同时接触点的数目相等;提出了间齿刃磨剃齿刀在剃齿加工过程中可以满足剃齿区域间的平衡条件,能较好地解决齿形中凹问题,弥补剃齿加工的工艺缺陷.该技术通过合理选择间齿的削薄方式及削薄量,就可实现平衡剃齿无法达到的齿形加工精度.经大量的生产实践应用验证:剃齿刀间齿刃磨技术是一种简便、可行、高效的工艺技术.
The gear shaving,which is widely applied to the manufacturing of the automobile, the tractor and mechine tools, is a traditional process of high-efficiency on the gear precision work, but the standard gear shaving tool when shaving can produce the flank concave, affecting the gear tooth profile processing precision and the gear transmission quality （high noise, low life）. In this paper the balance shaving condition is inferred from the analysis of gear shaving process, namely, in the shaving process, the contact point number should be the same on the two sides of shaving tooth face while gnawed in the vanishing line, It is therefore proposed that the gear shaving tools by raker sharpening can meet the equilibrium condition between the shaving area in the gear shaving process, avoid the flake concave and remedy the shaving processing craft defect. By choosing raker and thin cut quantity, this technique helps achieve the processing precision that the balanced gear shaving can＇t do. This technique, applied and tested in production, is simple, feasible, and efficient.
