A Highly Reliable Power Slip Ring

Abstract

The invention discloses a high-reliability power collector ring which comprises an inner conductor, an outer conductor, an inner shaft, a plurality of layers of collection assemblies and an installation assembly. The inner shaft is provided with an inner cavity, wherein the collection assemblies are respectively connected with the outer conductor and the inner conductor; the inner conductor is inserted in the inner cavity of the inner shaft; the collection assemblies are connected with the outer conductor; the collection assemblies are insulated from each other; the inner conductor, the outer conductor, the inner shaft and the collection assemblies are fixed by the installation assembly to form an integrated structure; and the collection assemblies are respectively connected with an external power circuit by the outer conductor to collect power of the external power circuit into the inner conductor. According to the invention, the collection assemblies can be flexibly configured according to the specific use environment so as to improve the conduction power; and meanwhile, the high-reliability power collector ring has small friction moment and long service lifetime and also has the characteristics of high reliability, compact structure, suitability for high power transmission and the like.

Description

technical field

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

[0002] Slip rings have a wide range of demands in the fields of aerospace, aviation, navigation and various precision instruments. The bus ring is used to realize the transmission of electric power or electric signal between two relatively rotating parts, so as to avoid twisting and breaking the wire during relative rotation.

[0003] According to the different friction modes, the slip ring can be divided into three types: solid sliding slip ring, liquid sliding slip ring and rolling slip ring. Although the current manufacturing technology of solid slip rings is relatively mature and is being widely used in various rotating interfaces, the friction torque of slip rings is large, the surface wear of sliding contact is serious, and the fluctuation resistance is large, which will be difficult to meet the higher lev...
