Problems solved by technology

[0002] Slip rings are widely required in the fields of aerospace, aviation, navigation, and various precision instruments. By using slip rings to realize the transmission of electrical power or electrical signals between two relatively rotating parts, it is possible to avoid winding and twisting the wires during relative rotation. broken; at present, the existing slip ring is a single-layer structure; thus, the axial dimension of the slip ring is large, and it cannot meet the requirements in the case of strict height requirements

Abstract

The invention discloses a collector ring with a double nested structure. The collector ring comprises an inner collector ring and an outer collector ring, wherein the outer collector ring sleeves thecircumferential side of the inner collector ring; the inner collector ring comprises an inner shell and an inner core shaft; the inner core shaft is rotationally arranged on the inner shell; the outercollector ring comprises an outer shell and an outer core shaft; the outer core shaft is hollow and is rotationally arranged on the outer shell around the inner collector ring; conductive ring assemblies are fixedly arranged in the middles of the inner core shaft and the outer core shaft along the axial directions; brush assemblies which are connected with the conductive ring assemblies in an adaptive sliding manner are fixedly arranged on the inner shell and the outer shell separately; and the inner core shaft and the outer core shaft are fixedly connected with a transmission part and rotatealong with rotation of the transmission part. The collector ring has the advantages that the radial space of the collector ring is fully utilized through inner and outer double layer distribution ofthe collector ring, the overall height dimension of the collector ring is reduced, and meanwhile, more signal loops can be arranged.

Description

technical field [0001] The invention relates to the technical field of slip ring devices, in particular to a slip ring with a double-layer nested structure. Background technique [0002] Slip rings are widely required in the fields of aerospace, aviation, navigation, and various precision instruments. The use of slip rings to realize the transmission of electrical power or electrical signals between two relatively rotating parts avoids twisting the wires during relative rotation. broken; at present, the existing slip ring is a single-layer structure; thus, the axial dimension of the slip ring is large, and cannot meet the requirements in the case of strict height requirements. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art above, to provide a double-layer nested structure that makes full use of the radial space of the slip ring, reduces the overall height of the slip ring, and satisfies the arrangeme...
