Abstract

The invention relates to the current of collector rings, and specifically relates to a long-life collector ring based on rolling-sliding combination. The long-life collector ring comprises an inner ring, wherein the outer circumferential surface of the inner ring is provided with a conducting ring, and an inner wire is led out from the conducting ring. The long-life collector ring further comprises an outer ring which is coaxially arranged on the outer side of the inner ring, and the inner ring is rotatably arranged on the outer ring; the outer ring is provided with a roller brush wire assembly, the roller brush wire assembly comprises a roller which is pressed on the outer ring surface of the conducting ring and can rotate relative to the outer ring surface of the conducting ring. The roller brush wire assembly further comprises a leading-out shaft which is fixedly arranged on the axis of the roller and is parallel to the axis of the conducting shaft, the leading-out shaft is sleevedwith a brush wire, and an outer wire is lead out from the brush wire. The long-life collector ring has the advantages that the life of the collector ring in the scheme is longer than that of the collector ring with a conventional structure, the processing requirement of the collector ring on parts is lower than that of the parts in the prior art, the structure is simpler, the stability is good, and the operation is reliable.

Description

technical field [0001] The invention relates to the field of slip rings, in particular to a long-life slip ring based on rolling-slip combination. Background technique [0002] Slip rings are widely used in aerospace, aviation, navigation, medical and various precision instrument fields, and are the core components of high-precision turntables. Its function is to realize the transmission of electric power or electric signal between two relatively continuous rotating parts, and avoid the winding and twisting of wires during relative rotation. The existing sliding slip ring technology is relatively mature and is widely used on various turntables, but the sliding electrical contact pair of the sliding slip ring inevitably has friction and wear, especially for large vias and large diameter slip rings. The increase of the sliding distance between the brush filament group and the conductive ring for one rotation relative to each other makes it difficult to guarantee the service l...
