摘　　要：推导了斜齿轮传动的接触线长度精确计算公式,分析研究了接触线长度的变化规律及啮合过程的动态统计规律,得到了动态统计规律下的接触线平均长度变化曲线图并进行了仿真,给出了端面重合度及纵向重合度的最佳组合及最差组合条件。基于MATLAB的编程算法,实现了对变位斜齿轮传动的接触线长度的计算和参数化调整,所得结论对斜齿轮的传动设计具有一定的理论意义和实用价值。The accurate formula of helical gear＇ s contact line length is derived, and then its changing law and dynamic statistical law of meshing process are analyzed, the dynamic statistical law of the contact line length change curve are obtained and simulated. The best and the worst condition of combination for transverse contact ratio and overlap ratio are given. Finally, based on the MATLAB programming algorithm, the variable helical gear contact line length calculation and parametric adjustment are realized, the conclusions have a certain theory significance and practi- cal value for the helical gear transmission design.
