[0002] Electrically conductive slip ring is a precision power transmission device for realizing power and signal transmission between two relative rotating mechanisms, and is widely used in robots, intelligent production lines, radar systems and the like. The electric transmission function of electrically conductive slip ring is mainly to realize the transmission of electric signals between rotating part and stationary part through wire and sliding friction pair, as shown in FIG. Figure 1 Electrically conductive slip ring is divided into rotating part and stationary part, and the rotating part and the stationary part are driven by mechanical interface to produce relative rotation, so as to realize n±360° unlimited rotation of the rotating part and the stationary part, as shown in FIG. Figure 2 The working principle of electrically conductive slip ring is that the rotating part and the stationary part are supported by bearings to form n±360° unlimited rotation, and power and signal transmission between the rotating part and the stationary part is realized by relying on the friction pair between the rotating part and the stationary part, as shown in FIG.
