为了改善加工参数较少的面齿轮传动的啮合性能,提出了用给定的啮合性能对面齿轮和小齿轮齿面进行拓扑修形设计的方法.面齿轮用插齿法加工,面齿轮与插齿刀的转角关系由预设的传动误差确定,由此确定面齿轮的拓扑修形齿面.然后用接触路径的位置及其方向和接触椭圆的大小构造小齿轮的拓扑修形齿面,该齿面用共轭点接触法磨齿加工,建立了小齿轮拓扑修形齿面与加工参数之间的线性方程.结果表明:齿面接触分析(TCA)获得的传动误差、接触路径与预设的传动误差、接触路径相同,TCA仿真的椭圆长度与预设椭圆长度相差范围为0.175 2~1.16mm.
In order to improve the meshing performance of face gear transmission with fewer machining parameters, a method of topological design of face gear and pinion gear with given meshing performance is proposed. Face gear is machined by gear insertion, The corner relationship of the knife is determined by the preset transmission error, thus determining the topographically modified tooth surface of the face gear, and then the topological modified tooth surface of the pinion gear is constructed by using the position of the contact path and the direction thereof and the size of the contact ellipse, Surface conjugate point contact grinding method was used to establish the linear equation between tooth surface topography and processing parameters.The results showed that the transmission error obtained from tooth surface contact analysis (TCA), the contact path and the presetting The transmission error and the contact path are the same. The difference between the elliptical length of the TCA simulation and the preset elliptical length is 0.175 2 ~ 1.16mm.
