摘　　要：针对非圆齿轮副的节曲线及其齿形复杂性、多样化及难以进行测绘与加工的特点,提出了采用测量的方法获得非圆齿轮副齿数、中心距、全齿高、压力角及齿顶曲线的数值,并通过反复计算确定这对非圆齿轮副的模数、齿顶高系数及径向间隙系数值,从而得到一个非圆齿轮的节曲线,并采用共轭节曲线的设计方法,获得另一个非圆齿轮的节曲线.利用提出的方法,对两对实际应用的非圆齿轮副进行了测绘设计与加工,取得了很好的使用效果.In order to make the designing and manufacturing of non-circular gear easier, a method to obtain the parameters of non-circular gear is presented. The method includes that 1) using the mapping method to obtain the number of teeth, the center distance, the tooth depth, the pressure angle and the tip curve of a non-circular gear pair; 2) using calculating method time and again to determine the module, the coefficient of addendum and the coefficient of tip of the non-circular gear pair and then one non-circular gear's pitch curve of the non-circular gear pair is obtained; 3) using conjugate pitch curve method to obtain another non-circular gear's pitch curve of the non-circular gear pair. Applying the method presented in this paper, two pairs of real non-circular are designed and manufactured, which proves the method to be feasible and effective.
