A brush assembly for a space slip ring

Abstract

The invention discloses an electric brush assembly for a spatial slip ring, and relates to the technical field of the glue pouring technology of precise electromechanical assemblies. The electric brush assembly comprises a brush assembly, a tool body and a press plate. The tool body is disposed at the bottommost end. The upper surface of the tool body is provided with a double-arc-shaped groove. The brush assembly is fixedly disposed on the upper surface of the tool body, and the shape of a contact surface of the brush assembly and the tool body is consistent with the shape of the double-arc-shaped groove on the upper surface of the tool body. The press plate is rectangular, and is fixedly installed on the upper surface of the tool body. The brush assembly comprises a brush carrier, a brush and a leading-out wire. Two sides of the upper surface of the tool body are symmetrically provided with notches. The center of the upper surface of the tool body is provided with a convex block. Two sides of the convex block in the axial direction are provided with arc-shaped grooves. According to the invention, the invention also proposes a glue pouring technological method for the electric brush assembly, guarantees the firm binding of all parts of the electric brush assembly, and meets the application requirements of the spatial environment of a spacecraft.

Description

technical field [0001] The invention relates to the technical field of glue filling technology for precision electromechanical components, in particular to a brush component for a space slip ring. Background technique [0002] In various spacecraft attitude control systems, precision conductive slip rings are precision electromechanical devices that transmit power current and control signals between two relative rotating mechanisms. With the rapid development of space application requirements such as various satellites, manned spacecraft, and space stations, conductive slip rings, as a key component of the commonly used actuators of spacecraft attitude control systems, determine the control accuracy, reliability and life of attitude control systems. Due to the particularity of its space application environment, the conductive slip ring must be able to work stably, continuously and reliably for a long time. Once the slip ring fails, it will directly affect the work of the att...

With the rapid development of space application requirements such as various satellites, manned spacecraft, and space stations, conductive slip rings, as a key component of the commonly used actuators of spacecraft attitude control systems, determine the control accuracy, reliability and life of attitude control systems. Due to the particularity of its space application environment, the conductive slip ring must be able to work stably, continuously and reliably for a long time. Once the slip ring fails, it will directly affect the work of the attitude control system, and in severe cases, it may cause the normal operation of the entire spacecraft to be interrupted.
