摘要
针对弧齿锥齿轮的切齿和啮合过程，建立了用数字仿真技术研究锥齿轮齿面形成和轮齿啮合过程的方法。在该方法中，将齿面切制时的线共轭条件转化为约束极值问题，据此获得被切齿面的数值模型；将轮齿啮合时的点共轭条件转化为在两齿面上求距离最近的点，并借助齿面数值模型，获得接触印痕和传动误差。用本文方法进行了某航空弧齿锥齿轮的切齿和啮合过程的数字仿真。
The conventional methods for determining the tooth geometry and tooth contact of spiral bevel gears are based on differential geometries of rigid body movement,and consequently make description of tooth surface and analysis of tooth contact behavior very complicated.In this paper,the authors work out a digital simulation method for tooth cutting and meshing of spiral bevel gears.A numerical model of tooth surfaces is set up by digital simulation of tooth cutting.The analysis of tooth contact behavior is completed with the numerical model of tooth surfaces.Solution of the meshing equation v·n=0 in conventional methods is replaced by minimizing the normal distance between points on the tooth surfaces in our method.The results of digital simulation for the spiral bevel gears used in a Chinese aeroengine show that the presented method describes the tooth shape and tooth contact characteristics more conveniently and efficiently,and can determine optimal cutting adjustment parameters for obtaining spiral bevel gears with good contact quality.
