The reason for the wear of the ball screw.

Release time: 2023-07-12

A ball screw is a common transmission mechanism in mechanical transmissions, and its basic structure consists of a threaded screw, a nut, and balls. During the operation and use of the ball screw, different forms of wear may occur on the surface due to various factors. According to the wear mechanism, the wear of the ball screw can be divided into several types:

1、Fatigue wear: Fatigue wear is a common form of wear during long-term operation of the ball screw. When the ball screw operates at high speed for a long time, there will be slight displacement and deformation between the ball and the raceway, causing micro-cracks on the surface of the ball and raceway. Over time, these cracks will expand and connect with each other, forming fatigue cracks, which eventually lead to fatigue wear on the surface. Fatigue wear can cause the precision of the ball screw to decrease and the noise to increase.

2、Abrasive wear: Abrasive wear is a form of wear that occurs when there are abrasive particles, dust, and other impurities on the surface of the ball screw. During operation, these impurities will rub against the ball and raceway, causing surface wear of the screw. Inappropriate operation and use, such as overloading or improper assembly, can also cause abrasive wear.

3、Corrosive wear: Corrosive wear is a form of wear that occurs when the ball screw is exposed to a humid and corrosive environment for a long time. In this environment, the metal on the surface of the screw will be oxidized and corroded, causing the shedding and wear of small particles on the surface. Corrosive wear reduces the service life and precision of the ball screw.

4、Impact wear: Impact wear is a form of wear that occurs when the ball screw is impacted or hit during operation. In this case, the surface of the screw will be damaged and scratched, causing an increase in surface roughness and affecting the precision and service life of the screw.

The above wear mechanisms may coexist during the operation of the ball screw. Therefore, when using and maintaining the ball screw, it is necessary to reduce the occurrence and impact of wear to ensure its long-term stable operation and use. Specifically, the following measures can be taken:

1、Regularly inspect and maintain the ball screw, clean the surface and replace worn parts in a timely manner.

2、Control the load of the ball screw and avoid overloading or improper use.

3、Choose a suitable working environment and lubrication method to prevent corrosion and wear.

4、Select high-quality ball screws and related accessories to improve the service life and precision of the ball screw.Carry out reasonable installation and debugging to ensure the matching and installation quality of the ball screw and related accessories.

5、Carry out reasonable installation and debugging to ensure the matching and installation quality of the ball screw and related accessories.

In summary, the wear of the ball screw is a complex dynamic process, and corresponding preventive and maintenance measures should be taken according to the wear mechanism to ensure its long-term stable operation and use.
