摘　　要：针对针摆传动中的高精度要求,给出了求最佳修形量的优化方法,在对齿廓修形产生的几何相对转角进行计算的基础上提出了弓背齿廓,进行了理论分析研究,并通过动态受力分析方法得到齿面接触力和接触应力.采用弓背齿廓修形方式计算结果表明,最佳弓背齿廓修形可以获得较小几何相对转角,有效减小回转误差,实现高精度传动,以适用于有高精度要求的针摆传动中.According to the precision requirement of pin-cycloid gear transmission,it gave the best method to obtain the optimal modification values,put forward arch back teeth profile on the basic of the calculation of the geometric relative rotated angle producing by the profile modification,and proceeded the theoretical analysis and studied on it,and then got the tooth surface contact force and the contact stress through the dynamic analysis method.The calculation results of arch back teeth profile modification show that the optimal arch back teeth profile modification can get smaller geometric relative rotated angle and reduce the rotary errors effectively,achieve high precision transmission and suitable for pin-cycloid transmission that requires for high precision.
