为方便实现渐开线圆柱齿轮接触分析,开发出渐开线圆柱齿轮啮合接触分析和齿廓修形算法程序.采用渐开线直齿轮参数方程精准建模,获得齿廓接触点的曲率半径,在考虑实际载荷的情况下,改进了赫兹接触公式来求解齿轮啮合接触应力.为减缓齿轮啮合冲击,在算法程序中提供了 5种齿廓修形方式及其修形后的接触应力分析方法.与行业公认的齿轮设计仿真软件MASTA计算结果进行对比.结果表明,该算法程序接触应力求解精度较高,相对MASTA平均误差约为5.04％,齿廓修形后的接触应力分布一致,验证了该算法程序的合理性.
Contact calculation and simulation analysis of the involute cylindrical gear
To facilitate the contact analysis of involute cylindrical gears,a meshing contact analysis and tooth profile modification algorithm program for involute cylindrical gears is designed.The involute spur gear parameter equation is employed to accurately model the radius of curvature of the tooth profile contact point,and the Hertz contact formula is enhanced to solve the gear meshing contact stress considering the actual load.To reduce the impact of gear meshing,five tooth profile modification methods and their contact stress analysis methods after modification are given in the algorithm program.Compared with the calculations by MASTA,the industry-recognized gear design simulation software,the algorithm program has a higher accuracy in solving the contact stress and the contact stress distribution after tooth profile modification accords with the MASTA calculation results,and the average error is about 5.04％,which confirms the rationality of the algorithm program.
