What kind of ball screw is used for rotary table intelligent assembly machine? Machine tool people must know the ball screw! For rotary table intelligent assembly machine many people do not know is that our life is full of small inventions, great progress of great technology, transmission technology is one of them. Our life is full of small inventions, great progress of great technology, transmission technology is one of them. Moving objects from one place to another in a straight line is called linear transmission, which is divided into two forms: sliding and rolling. As important as wheels are to transportation, ball bearings are also of great significance to linear transmission. With the continuous progress of science and technology, many transmission products have been derived, hiding in a variety of mechanical equipment, making people's lives more convenient.

Modern people are often amazed and curious about how those big projects in ancient times, such as the pyramids and the Great Wall were built, and how were those huge stones transported without large-scale industrial tools?

Transporting huge, heavy blocks, like the one pictured above, does require a lot of people. The ancients, however, were smarter than modern painters, and they knew early on that it was much more efficient to lay sleepers under stones than to drag them directly over the ground.

Ballscrew (Ballscrew), also called ball screw, guide screw, ball screw, ball screw, ball screw, ball spline... It is the most commonly used transmission mechanical component on lathes and precision machinery.

The history of people using screw to do transmission is not long. In 1898, people first tried to add a steel ball between the nut and the screw, converting the sliding contact of the traditional screw into rolling contact; By replacing sliding friction with rolling friction, the steel ball rotating motion in the nut is transformed into linear motion, and the torque is converted into axial repeated force, so as to improve the poor positioning and easy damage of the traditional screw.

In 1940, the ball screw was applied to the automobile steering device, which brought a huge revolution in its application, and gradually replaced the traditional ACME screw ball screw structure (ACME). This small invention has brought great progress in transmission technology.

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, good synchronization performance and other characteristics, ball screw has become one of the most widely used important components in the industry, especially in the precision technology industry, and the precision machinery industry positioning and measurement system.

Ball screw is widely used in the positioning accuracy control of various industrial machinery, Such as Precision machine tools, Industrial machinery, Electronic machinery, Transport machinery. Specifically, in various machine tools, robots, welding machines, measuring instruments, computer disk drive starter transmission, aircraft wing lift adjustment, propeller tilt Angle control, medical X-ray fluoroscopy devices. And other precision equipment, you can find ball screws.
