摘　　要：研究了一种利用螺旋旋转产生牵引力的无损伤微型机器人的驱动机构。详细分析计算了微型机器人在采用矩形、梯形和三角形圆柱螺旋时所产生的轴向摩擦牵引力和动压粘液膜承载量。通过对比三种螺纹下微型机器人的运动特性参数,得出微型机器人采用矩形螺纹最为合理。An impeller of non - invasive micro - robots through the generated thrust force by the rotation of screws is studied. The axial thrust force and the loud capacity of hydrodynamic pressure are analyzed and calculated in detail when rectangular or trapezoidal or triangular cylindrical screw is adopted in the microrobot. Through comparing the Locomotion parameters of the micro - robots with these three kinds of screws, it is concluded that it is more reasonable that rectangular screw is adopted in this micro - robot.
