The structure of the ball screw

Ball screw is an ideal product that converts rotary motion into linear motion, or converts linear motion into rotary motion.

The working principle of the ball screw mechanism is basically the same as the transmission principle between the nut and the screw. When the screw can rotate but the nut cannot rotate, rotate the screw. Because the nut and the load slider are connected with the guide parts (linear guide rail, linear bearing), the rotation freedom of the nut is limited, so that the nut and the connecting The loads together can only move in a straight line under the action of the guiding parts.
