Abstract

The invention discloses a high-speed long-life rotary electric connector, which comprises a shell, an electric brush assembly, an insulating ring, a conducting ring, an insulating bush, a bearing endcover, a shaft sleeve, a shaft, a bearing I and a bearing II, wherein the shaft is horizontally installed in the shell through the bearing I and the bearing II which are arranged at the two ends, andthe bearing end cover is arranged at the tail end of the shell; the shaft realizes high-speed relative rotation in the shell through the bearing I and the bearing II; the insulating bush and the shaftsleeve sleeve the shaft; the insulating ring and the conducting ring are arranged on the insulating bush; and the electric brush assembly is arranged on the outer side of the shell. The purpose of prolonging the life of the rotary electric connector is achieved.

Description

technical field [0001] The invention belongs to the technical field of rotary electrical connectors, in particular to a high-speed and long-life rotary electrical connector. Background technique [0002] Rotary electrical connector is a connector that realizes signal and electrical energy transmission in relative rotational motion, and is widely used in rotary electrical transmission between fixed end and rotating end of equipment. Generally, rotary electrical connectors mostly use sliding contact between brushes and conductive rings to realize electrical transmission. In order to ensure the reliability of electrical transmission, the brush needs a certain pressure to maintain sliding contact with the conductive ring. Due to the sliding friction between the brush and the conductive ring, wear and tear will inevitably occur between the brush and the conductive ring during rotation. In order to achieve reliable electrical transmission at high speeds, it is necessary to incre...
