Ball screw is a mechanical form of infinite rolling and circulation after installing steel balls into the screw shaft and nut raceway, so as to convert the rotating motion into linear positioning motion. In order to reduce the friction torque generated when the steel ball circulates in the raceway, the linear contact between the screw rod and nut raceway and the steel ball is designed as a point contact structure.

知识点！滚珠丝杠和普通丝杠的区别在哪里?

Knowledge point! What is the difference between ball screw and ordinary screw?

自锁性：自锁性一般与传统效率成反比，传动效率越高，自锁性就越小，因此，滚珠丝杠几乎没有自锁性，而普通丝杠（即梯形丝杠）具有一定的自锁性。

Self locking: self locking is generally inversely proportional to the traditional efficiency. The higher the transmission efficiency, the smaller the self-locking. Therefore, the ball screw has almost no self-locking, while the ordinary screw (i.e. trapezoidal screw) has a certain self-locking.

经济性：从以前和目前的情况来看，滚珠丝杠因其结构较梯形复杂，仍然比梯形丝杠高。不过，随着自动化设备的增多而产量大，差异越来越小。

Economy: from the previous and current situation, the price of ball screw is still higher than that of trapezoidal screw because its structure is more trapezoidal and complex. However, with the increase of automation equipment and large output, the price difference is becoming smaller and smaller.

传动速度：滚珠丝杠是滚动摩擦，梯形丝杠是滑动摩擦，工作时前者的温升远低于后者，因此可以承担高速传动任务。

Transmission speed: the ball screw is rolling friction and the trapezoidal screw is sliding friction. When working, the temperature rise of the former is much lower than that of the latter, so it can undertake the task of high-speed transmission.

使用寿命：滚动摩擦的表面损伤比滑动摩擦的小很多，因此在清洁、润滑等条件符合时，滚珠丝杠的维持寿命比梯形丝杠高得多。

Service life: the surface damage of rolling friction is much smaller than that of sliding friction. Therefore, when the cleaning, lubrication and other conditions are met, the maintenance life of ball screw is much higher than that of trapezoidal screw.

传动效率：滚珠丝杠由于滚动丝杠副的丝杠轴与丝杠螺母之间有很多滚珠在做滚动运动，所以运动效率高。

Transmission efficiency: the ball screw has high movement efficiency because there are many balls rolling between the screw shaft of the rolling screw pair and the screw nut.
