中文摘要:
      针对滚珠丝杠舵机常用的曲柄滑块和拨叉两种传动机构形式,对舵机的减速比和间隙特性进行对比分析研究。拨叉舵机的减速比波动较小,在0°时为最小值,两边呈现对称状态,而曲柄滑块舵机的减速比为不对称状态。曲柄滑块舵机比拨叉舵机产生间隙的环节较多,但间隙易于控制,而拨叉舵机由于结构磨损产生的间隙增大现象较为明显。
English Summary:
      Aiming at two common mechanisms of ball screw actuator for crank slider and shifting fork transmission, the paper gives contrast analysis of the speed down ratio and system clearance of actuatorIn terms of speed down ratio, the speed down ratio of shifting fork actuator fluctuates less, which becomes the minimum and symmetric at 0°While crank slider actuators speed down ratio doesnt have symmetry characteristicCompared with shifting fork actuator, crank slider actuator has more points contributing to system clearance, but it could be controlled easilyHowever, because of mechanic structure wear, the system clearance of shifting fork actuator increases more obviously.
