Ballscrew asic concepts
Ball screw, also known as ballscrew, lead screw, is a kind of steel ball that moves between the nut and the screw. The sliding contact of the traditional screw is converted into rolling contact, and then the rotary motion of the steel ball in the nut is converted into linear motion. Transmission mechanical components. The ball screw has the characteristics of high positioning accuracy, long life, low pollution, high-speed forward and reverse transmission and conversion transmission. Because of the above characteristics, the ball screw has become the recent positioning and measurement system in the precision technology industry and the precision machinery industry. One of the important components.

Ball screws movement principle
According to the national standard GB/T17587.3-1998 and application examples, the ballscrew (which has basically replaced the trapezoidal screw, has been commonly called the screw) is used to convert rotary motion into linear motion; or convert linear motion into rotary motion Actuating elements, and have high transmission efficiency, accurate positioning, etc.!
When the ball screw is used as the active body, the nut will be converted into linear motion according to the lead of the corresponding specification with the rotation angle of the screw rod. The passive workpiece can be connected through the nut seat and the nut to realize the corresponding linear motion.
Application industry
Since the development of the ballscrew, it has been widely used in the positioning accuracy control of various industrial machinery, such as precision machine tools, industrial machinery, electronic machinery, and conveying machinery. In addition to the above-mentioned applications in machinery, it is also used in the transmission of computer disk drive starters, the adjustment of aircraft wing lift, the tilt angle control of the propeller, and the medical X-ray fluoroscopy imaging device. The application range is extremely wide.
