Principle of ball screw transmission
The principle of ball screw transmission is: the ball screw as the driving body, the nut will be converted into linear motion with the rotation angle of the screw rod according to the lead of the corresponding specification, and the connecting workpiece can be connected with the screw rod nut through the nut seat, so as to realize the corresponding linear motion.
Linear guide rail, ball screw and motor base are the most commonly used transmission components in tool machinery and precision machinery. Their main function is to convert rotary motion into linear motion or torque into axial repetitive force. At the same time, it has the characteristics of high precision, reversibility and high efficiency. Due to its small friction resistance, ball screw is widely used in various industrial equipment and precision instruments.
