Rolling type collector ring

Abstract

The invention provides a rolling type collector ring, and relates to the technical field of rolling collector ring devices, in particular to the rolling type collector ring which comprises an outer wire, an outer conducting ring, a plurality of layers of collector ring assemblies, a plurality of layers of insulation assemblies, an installation assembly, an inner conducting ring, an inner wire andan inner shaft; the inner wire is electrically connected with the outer wire through the inner conducting ring, the collector ring assemblies and the outer conducting ring; the collector ring assemblycomprises the inner conducting ring, the outer conducting ring and a collector unit; the inner conducting ring and the outer conducting ring are concentrically arranged, and the collector ring assembly is rotatably and electrically connected between the inner conducting ring and the outer conducting ring.

Description

technical field

[0001] The invention relates to the technical field of rolling slip ring devices, in particular to a rolling slip ring. Background technique

[0002] The main function of the bus ring is to realize the transmission of electrical power or electrical signals between the fixed equipment and the rotating equipment, and to avoid the mutual winding of the wires when the equipment rotates relative to each other. It can be widely used in many fields such as aerospace, aviation, navigation, and various precision instruments.

[0003] According to different contact friction modes, slip rings can be divided into sliding friction slip rings and rolling friction slip rings. The manufacturing technology of sliding friction slip ring is relatively mature, and it is widely used in various rotating interfaces, but the sliding friction torque is large, the sliding contact surface is easy to wear, and the fluctuation resistance is large, which will greatly reduce the reliabilit...
