Ball screw is the most commonly used transmission element in tool machinery and precision machinery. Its main function is to convert rotational motion into linear motion, or convert torque into axial repeated force. It also has the characteristics of high precision, reversibility and high efficiency.

滚珠丝杠是工具机械和精密机械中最常用的传动元件。其主要作用是将旋转运动转化为直线运动，或将扭矩转化为轴向重复力。它还具有高精度、可逆性和高效率的特点。

Characteristics of ball screw transmission: The ball screw transmission mechanism uses the ball between the screw and the nut as an intermediate element, changing the sliding friction transmission between the screw and the nut into rolling friction transmission. The ball screw and nut are both equipped with arc-shaped spiral grooves. The two arc-shaped spiral grooves are combined to form a raceway. There are many balls installed in the raceway, so there is rolling friction between the screw and the nut. Ball retainers are installed at both ends of the spiral groove of the nut to block it, and there is a return pipe to allow the balls to roll out of the nut body from one end of the spiral groove, and then return to the other end of the raceway along this return pipe. In this way, when the ball screw rotates relative to the nut to perform linear motion feed transmission, the balls continuously roll in the spiral raceway.

滚珠丝杠传动的特点：滚珠丝杠传动机构利用丝杠与螺母之间的滚珠作为中间元件，将丝杠与螺母之间的滑动摩擦传动改为滚动摩擦传动。滚珠丝杠和螺母均设有弧形螺旋槽。两个弧形螺旋槽组合在一起形成滚道。滚道中安装了许多滚珠，因此丝杠和螺母之间存在滚动摩擦。螺母螺旋槽的两端装有挡球器将其阻挡，并设有回流管，使滚珠从螺旋槽的一端滚出螺母本体，再沿此回流管返回滚道的另一端。这样，当滚珠丝杠相对螺母旋转进行直线运动进给传动时，滚珠在螺旋滚道中连续滚动。

As a precise and labor-saving transmission mechanism, it is widely used in ball screws of precision machine tools and CNC machine tools.
