Abstract

The invention discloses a rolling confluence ring device suitable for transmission with large power. The device comprises an inner conductive wire, an outer conductive wire, an inner shaft, a plurality of layers of confluence assemblies and a mounting assembly, wherein the inner shaft is provided with a cavity; the layers of confluence assemblies are respectively connected with the outer conductive wire and the inner conductive wire, the inner conductive wire is arranged in the cavity of the inner shaft in a penetrating way, the layers of confluence assemblies are connected with the outer conductive wire, the layers of confluence assemblies are mutually insulated, and the inner conductive wire, the outer conductive wire, the inner shaft and the layers of confluence assemblies fixedly form an integral structure through the mounting assembly; and the layers of confluence assemblies are respectively connected with an external power circuit through the outer conductive wire so as to carry out confluence to the inner conductive wire for the external power circuit. By the adoption of the device, the confluence assemblies can be flexibly configured according to a specific use environment to improve conductive power; and meanwhile a friction torque is small, the service life is long, and the device further has the characteristics of high reliability, compact structure, adaptability to transmission with large power and the like.

Description

technical field [0001] The invention relates to the technical field of slip ring devices, in particular to a rolling slip ring device suitable for high power transmission. 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 di...
