Basic principles and structural characteristics of ball screw pair
Working principle of ball screw pair
1. Ball screw pair is a transmission mechanism that converts rotational motion into linear motion. Its core working principle is to achieve efficient energy transfer through the rolling of balls between the screw and nut
2、 When the screw rotates, the ball rolls in the spiral groove, driving the nut to move along the axial direction of the screw, thereby converting the rotational motion into linear motion
3、 Ball screw pairs have the characteristics of high precision, high efficiency, and high rigidity, and are widely used in various industrial equipment< Structural characteristics and advantages analysis
1. Compact structure
The ball screw pair uses rolling friction instead of sliding friction, making the entire mechanism more compact and reducing installation space.

2、 High load-bearing capacity: Ball screw pairs have a high load-bearing capacity and can withstand large axial and radial loads
3、 High precision
Due to the small rolling friction coefficient of the ball bearings and high transmission efficiency, high-precision positioning and control can be achieved
4、 The rolling friction method of the ball screw pair reduces wear and extends its service life.
