How does a ball screw work?

With the development of society, an increasing number of industrial components have appeared in people’s lives. Different categories of industrial components have their own characteristics in different filed.

Today, we will focus on the introduction of a ball screw, given that there are a lot of people who know How does a ball screw work. In this article, a ball screw will be clearly shown.

What's a ball screw?

First and foremost, let’s have an overview of a ball screw. A ball screw is a Mechanical Linear Actuator that transforms rotary motion into linear motion with very little friction. Threaded shafts provide the helical raceways for ball bearings, which act as precision screws.

The ball screw is comprised of five major parts, which are a screw, nut, ball, pre-pressure plate, reverser, and dust collector. Its function is to convert rotary motion into linear motion.

The working principle of a ball screw.

According to the national standard, a ball screw is an actuator used to convert rotary motion into linear motion or linear motion into rotary motion.

When a ball screw is used as an active body, the nut is converted into a linear motion with the angle of rotation of the screw according to a guide of the corresponding specification, and the passive workpiece can be connected to the nut via the nut socket, thus achieving a corresponding linear motion. It is characterized by high transmission efficiency and accurate positioning.

What are the ball screw applications?

When talking about the ball screw application, it’s worth pointing out its characteristics. The main function of a ball screw is to convert rotary motion into linear motion. It is characterized by high precision, reversibility, and efficiency. Due to their low frictional resistance, they are used in a wide range of industrial equipment and precision instruments. It is therefore used in a wide range of industrial equipment and precision instruments.

In many industrial projects, ball screw assemblies can be applied to move a heavy and large-scale object. Meanwhile, it also can be used for adjusting the wing flaps on an airplane. It plays a vital role in the contemporary industry.

What are the main characteristics of a ball screw?

As mentioned before, a ball screw has the characteristics that low frictional losses and high transmission efficiency. Besides, ball screws have a high degree of precision because it’s consistently produced with the highest level of machinery and equipment in the world. Especially in the factory environment, where grinding, assembly and inspection processes are carried out. Temperature and humidity are strictly controlled by the ball screw manufacturers, and precision is fully guaranteed by a comprehensive quality management system.

However, there are some issues that need to be noticed. One disadvantage of ball screws is that they require a lot of lubrication. Ball screws should always be adequately lubricated with the right formula to prevent corrosion, reduce friction, ensure efficient operation, and prolong service life.
