Key factors in determining the quality of the slip rings

The status of the slip ring in various automatic control systems determines the importance of the quality control of the junction ring. First of all, we need to make a systematic analysis of the working principle, internal structure, usage and other aspects of the sliding ring from the technical level, and find out the key factors affecting the quality of the slip ring.

According to the working principle of the slip ring, we can know that the slip ring is a sliding contact. The friction of the sliding process will cause the wear of the contact surface, and the wear of the sliding ring determines its working life. The smaller the wear, the longer the life of the electric slip ring. But must it be that the less the wear, the better? Shenzhen HongRuiming electronics through a large number of experiments can see that different materials of mechanical wear resistance, contact force of the material wear resistance is not the same. The hardness of the material, the friction coefficient, electric corrosion resistance and current density of the material itself determine the wear of the electric slip ring during operation. Secondly, the larger contact force will also wear the slip ring too early, but the too small contact force may also cause the contact resistance to increase, or even spark. Ensure the stable transmission of electric slip ring. Material selection and production process become the key to slip ring quality control. The material determines the wear resistance of the electric slip ring, and the production process can ensure that the force point is uniform at different angles. Of course, we also need to consider the matching problem of various materials in different applications in order to optimize the performance of the conductive slip ring.
