Ball screws are used in many machinery and automation equipment. There are many cases where ball screws are used in modules. What is a linear module? Linear module is a linear transmission device, there are two main ways. One is composed of ball screw and linear guide, and the other is composed of synchronous belt and synchronous pulley. Linear modules have a wide range of use, easy installation and high precision, and are accepted by the majority of users! The specific link of making the structure of linear motion by yourself is omitted.

Ball screw is an ideal product for converting rotary motion into linear motion, or converting linear motion into rotary motion. A TBI ball screw consists of a threaded rod, a nut and balls. Its function is to convert rotary motion into linear motion, which is a further extension and development of the ball screw. The important significance of this development is to change the bearing from rolling action to sliding action. Due to its small frictional resistance, ball screws are widely used in various industrial equipment and precision instruments.

Ball screw is a transmission element often used in machine tools and precision machinery. Its main function is to convert rotary motion into linear motion, or convert torque into axial repetitive force, with high precision, reversibility and high efficiency. specialty. Ball screw is also called ball screw and ball screw.

The main linear module features of the application of the ball screw in the module are as follows:

1) High positioning accuracy

The ball screw pair realizes rolling friction in the way of ball rolling between its nut and the screw rod. The motion of the rolling linear guide is realized by the rolling of steel balls. . The repeatable positioning accuracy is high, and it is suitable for moving parts that are frequently started or reversed.

2) Small wear and tear

Due to the small frictional energy consumption of the rolling contact, the frictional loss of the rolling surface is also reduced accordingly, so the rolling linear guide system can be kept in a high-precision state for a long time. At the same time, because the use of lubricating oil is also very small, it is very easy to design and maintain the lubrication system of the machine tool.

3) High life expectancy

For the nut of the ball screw pair, the hardness of the screw reaches HRC58-62, the hardness of the ball reaches HRC62-66, and there is rolling friction between them, so it can achieve high fatigue life and precision life.

4) Adapt to high-speed sports

Due to the small frictional resistance of the module using the rolling linear guide, the required power source and power transmission mechanism can be miniaturized, and the driving torque can be greatly reduced. It can realize high-speed linear motion and improve the working efficiency of the machine tool.

5) Strong bearing capacity

The rolling linear guide has good bearing performance and can withstand forces and moment loads in different directions, such as the force in the up, down, left, and right directions, as well as the bumping moment, the shaking moment and the swinging moment. Therefore, it has good load adaptability.

6) Easy to assemble and interchangeable

The ball screw and rolling guide are interchangeable, and the module can regain high precision as long as the slider or guide rail or the entire rolling guide pair is replaced.

7) Micro and high-speed feed can be realized

The ball screw pair does not produce sliding phenomenon, and can realize micro-feed; as long as the feed pulse is small enough in the linear module configuration, the ball screw pair can achieve micron-level feed. Because of the low heat generation of the ball screw pair and the ability to manufacture a large lead screw, high-speed feed can be achieved.
