摘要
基于弧齿锥齿轮齿面3坐标测量网格点数据,采用齿面间距计算的局部坐标法、齿面最小间距计算的流水法、齿面最小间距调整的无约束优化法和高精度齿面逐级加密等离散数值齿面啮合分析技术,得到了离散数值齿面的啮合印痕和传动误差曲线。以发动机传动系统中的1对弧齿锥齿轮为例,验证了数值计算技术的可行性。结果表明:测量齿面数据隅于轮齿范围之内,该技术也可用于检测弧齿锥齿轮加工质量,并为真实齿面加工参数反求和重构提供输入数据。
Based on grid data of tooth surfaces formed by Coordinate Measuring Machine （CMM）, the tooth contact pattern and transmission errors of discrete numerical toothcontact were obtained by local coordinate method to calculate tooth surface gap, water flow method to pinpoint the smallest tooth surface gap, optimization method to regulate the smallest tooth surface gap, and stepwise grid refinement of tooth surface to ensure precision. An example was taken for a pair of spiral bevel gears in aviation engine to verify the proposed techniques. The results show that the CMM data is confined in the boundary of tooth surface, and the techniques could be applied to the inspection of spiral bevel gears, and provide input data for inverse engineering of manufacture parameters of tooth real surface and its reconstruction.
