What are the advantages of ball screw

2020-09-30

Ball screw transmission system is a rolling screw transmission system with ball as rolling medium. In the form of transmission, it can be divided into two types: Turning rotary motion into linear motion; transforming linear motion into rotary motion.

1、 High transmission efficiency

The transmission efficiency of the ball screw transmission system is as high as 90% ~ 98%, which is 2 ~ 4 times of the traditional sliding screw system. For example, it can get a larger thrust with a smaller torque, and can also change from linear motion to rotary motion (reversible motion).

2、 The movement is smooth

The ball screw transmission system is point contact rolling motion, which has low friction resistance, high sensitivity, no vibration when starting and no crawling phenomenon at low speed. Therefore, micro feed can be controlled precisely.

3、 High precision

The ball screw transmission system has small temperature rise in motion, and can pre tighten to eliminate axial clearance and pre stretch the lead screw to compensate for thermal elongation, so it can obtain high positioning accuracy and repeated positioning accuracy.
