As a mechanical person, do you know the history of the development of ball screws?

If you are in the bearing machinery industry, you should understand the history of ball screw development. If you don't understand, when others let you talk about the development of the ball screw, you don't know, you will feel very embarrassed! Next, YWS takes you through the history of ball screw development.

Our life is full of great technology of small inventions and great progress. Transmission technology is one of them. Moving an object from one place to another in a linear motion is called a linear drive and is divided into sliding and rolling forms. Like the importance of wheels for transportation, balls are also of great importance to linear drives. With the continuous advancement of technology, many transmission products have been derived, hiding in a variety of mechanical equipment, making people's lives more convenient.

Modern people often marvel at and wonder how ancient projects such as the pyramids and the Great Wall were built. Without large industrial tools, how are the huge stones transported?

Transporting huge and heavy stones, indeed, like the picture above, requires a lot of people. However, the ancients were smarter than the modern people. They knew very early that the rolling of the wood beneath the stones was much more efficient than dragging directly on the ground.

Ballscrew, also known as lead screw, ball screw, screw, ball spline. . . It is the most commonly used transmission mechanical component on lathes and precision machinery.

The history of using a screw to make a transmission is not long. In 1898, for the first time, people tried to add steel balls between the nut and the screw to convert the sliding contact of the traditional screw into a rolling contact; instead of sliding friction by rolling friction, the steel ball in the nut was rotated and turned into linear motion. The torque is converted into an axial repetitive force to improve the positioning and damage of the conventional screw.

In 1940, the ball screw was applied to the steering device of the car, which brought about a huge revolution in its application, and gradually replaced the traditional Acme screw ball screw structure (ACME). This small invention has brought tremendous advances in transmission technology.

Ball screw has become an industry because it can be converted in linear motion and circular motion, and has good friction, high transmission efficiency, high positioning accuracy, transmission reversibility, long service life, low pollution, and good synchronization performance. One of the most widely used and important components in the precision technology industry, as well as in the positioning and measurement systems of the precision machinery industry.

Ball screws are widely used in the positioning accuracy control of various industrial machines, such as Precision machine tools, Industrial machinery, Electronic machinery, and Transport machinery. Specifically, the transmission of various machine tools, robots, welding machines, measuring instruments, computer disk drive starters, adjustment of aircraft wing lifts, tilt angle control of propellers, and medical X-ray fluoroscopy devices. On the precision equipment, you can find the ball screw.
