Abstract

The kinematics of a planetary roller–screw gear, which converts the rotational motion of a drive nut connected to an electric motor into the translational motion of a screw, is calculated. The nut is threaded with rollers arranged concentrically around the screw via two separators connected to the rollers by pins. A formula is derived to calculate the screw speed depending on the frequency of nut rotation and the variation of the thread parameters on the nut, the rollers, and the screw.

带有驱动螺母的行星滚子-丝杠齿轮的运动学

摘要

计算出行星滚子-螺杆齿轮的运动学，该运动将与电动机连接的驱动螺母的旋转运动转换成螺钉的平移运动。螺母上带有滚子，滚子通过两个通过销钉连接到滚子上的隔板，同心地围绕螺丝排列。根据螺母旋转的频率以及螺母，滚子和螺钉上的螺纹参数的变化，得出一个公式来计算螺钉速度。
