Automatic centering and damping brush component for collector ring

Abstract

The invention discloses an automatic centering and damping brush component for a collector ring. The automatic centering and damping brush component for the collector ring comprises a brush and an automatic damping mechanism, wherein the automatic damping mechanism is used for mounting the brush and comprises a connector and two brush connecting plates; the two brush connecting plates are arranged at two sides of the connector respectively; one end of each brush connecting plate is hinged with the connector body and the other end is hinged with a fixed block connected with the brush; the brush connecting plates are in an elongated plate-like structure; the two brush connecting plates are connected with each other through an elastic element, so that the distance between the two brush connecting plates can change along with expansion and contraction of the elastic element; the middle part of the elastic element is supported on an extension plate of the connector; and the brush is hinged with the fixed block. The invention aims at providing the brush component which can still reliably contact a conductive ring in the radar collector ring under the conditions of strong impact and strong vibration.

Description

technical field [0001] The invention relates to a radar slip ring assembly, in particular to a slip ring automatic centering vibration damping brush assembly. Background technique [0002] The brush assembly is an important channel for the signal transmission of the radar slip ring. It is installed between the stator and the rotor to realize the signal transmission from the moving ring to the fixed ring. With the increasing requirements of radar signal transmission, radar often needs to work under the conditions of strong shock and strong vibration, such as high temperature, humid heat, low temperature, salt spray, shock and vibration environment, in this case It is still necessary for the brush assembly in the radar to be in reliable contact with the conductive ring in the slip ring, not only to ensure that there is sufficient pressure during the contact process, but also to ensure that the contact area is large enough. [0003] However, the existing brush assembly cannot ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the problem that the existing brush assembly cannot keep in good contact with the conductive ring in the radar slip ring under the condition of strong shock and vibration, and to provide an automatic centering vibration damping electric brush assembly. Brush assembly, the brush assembly can still be in reliable contact with the conductive ring in the radar collector ring under the condition of strong shock and vibration, ensuring stable signal transmission
