摘　　要：根据内摆线发生原理,设计了齿轮转动导杆机构;采用旋转矢量微分法,给出了机构的运动矩阵方程,研究了内摆线瓣数和摇块位置对机构运动特性的影响。结果表明,内摆线瓣数只影响转动导杆角速度的波动,而对其速度波动几乎无影响;摇块设定在瓣尖一侧对称线上时,转动导杆角速度尖脉冲出现两次,而设定在内摆线中心点以外的其余位置时,角速度尖脉冲仅出现一次;摇块位置只影响转动导杆作匀加速运动时的行星轮相位角,而对做匀减速运动时的行星轮相位角无影响。According to the principle of cycloid generation,the gear rotating guide bar mechanism is designed.The motion matrix equation of the mechanism is given by the method of rotation vector differentiation,and the influence of the number of cycloid lobes and the position of the rocker on the motion characteristics of the mechanism is studied.The results show that the lobe number of the hypocycloid only affects the rotating guide-bar on the angular velocity pulsation,but has little effect on the velocity pulsation.There will be two spike pulses on the angular velocity of the rotating guide-bar when the oscillating slider is located at the axisymmetric line on the sharp corner side,which however would be only one at other locations except center of the hypocycloid.The position of the rocking block only affects the phase angle of the planetary gear during uniform acceleration motion of the rotating guide rod,but it has no effect on the phase angle of the planetary gear during uniform deceleration motion.
