A rolling 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 present invention relates to the technical field of rolling collector ring devices, in particular to a rolling collector ring. Background technique [0002] The main function of the bus ring is to realize the transmission of electric power or electric signal between the fixed equipment and the rotating equipment, and to avoid the entanglement of the wires when the equipment rotates relatively. It can be widely used in many fields such as aerospace, aviation, navigation and various precision instruments. [0003] According to different contact friction methods, the confluence ring can be divided into sliding friction confluence ring and rolling friction confluence ring. The manufacturing technology of the sliding friction type bus ring is relatively mature and is widely used in various rotating interfaces. However, the sliding friction torque is large, the sliding contact surface is easy to wear, and the fluctuation resistance is large. This will greatly r...

AI Technical Summary

Problems solved by technology

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 reliability of the slip ring and affect the The safety of the equipment increases the maintenance cost of the equipment
