The lead screw is a transmission component that converts rotary motion into linear motion or linear motion into rotary motion, and is widely used in various mechanical equipment. Its main function is to convert rotational motion into linear motion, or to convert torque into axial repeated force, with high precision, reversibility and high efficiency.

Classification and structure

The lead screw can be divided into three types according to its friction characteristics: sliding lead screw, rolling lead screw and static pressure lead screw. The sliding screw has the advantages of simple structure and convenient manufacture, but low precision and efficiency. Rolling screw is divided into ball screw and roller screw, ball screw has the characteristics of high precision, high efficiency and low friction, and roller screw is suitable for high precision, high-speed, heavy duty applications.

Application field

Lead screw is widely used in CNC machine tools, manufacturing equipment, robots, precision instruments and other fields. In humanoid robots, the lead screw also plays an important role, such as the Tesla Optimus robot uses the roller lead screw and ladder lead screw, driving the growth of the lead screw market.

Historical background and development trend

The history of the application of the lead screw can be traced back to the end of the 19th century, when people began to try to place the steel ball between the nut and the screw to reduce friction. With the development of industry, ball screw has gradually replaced the traditional sliding screw and become a widely used transmission component in the industry.
