Collector ring for high temperature and high humidity environment

Abstract

The invention discloses a collector ring for a high temperature and high humidity environment. The collector ring comprises a ring core, an electric brush and a shell; the electric brush is connectedto the inner surface of the shell, and the end of the electric brush is in sliding contact with a metal ring on the ring core; a cavity is formed in the shell, and is internally provided with a dryingcomponent and a cooling device. The collector ring has the advantages that heat generated by the collector ring during high-speed operation can be dissipated timely, and accordingly, the temperatureof the collector ring is prevented from being ultrahigh; the drying component can effectively absorb water vapor in the shell to achieve effective dehumidification, and accordingly, a good working environment for the collector ring is formed to guarantee normal working of the collector ring in the high temperature and high humidity environment; therefore, the service life of the collector ring isprolonged, and the electric conductivity of the collector ring is stable.

Description

technical field [0001] The invention relates to the technical field of slip rings, in particular to a slip ring used in high-temperature and high-humidity environments. Background technique [0002] The slip ring can ensure the continuous rotation and at the same time, in the electromechanical system that transmits power and signals from the fixed position to the rotating position, it can avoid the sprain caused by the wire during the rotation. [0003] There are many parts on the confluence ring. The friction pair composed of the brush and the slip ring on the ring core is the most important part to complete its function. During the operation of the confluence ring, the friction pair composed of the brush and the slip ring There will be a lot of wear and tear, and when the wear reaches a certain level, the corresponding components need to be maintained or replaced, especially for some precision instruments, in order to ensure. There are many factors that affect the wear of...

Problems solved by technology

There are many factors that affect the wear of the friction pair. In addition to the speed, contact load, and material properties, it is also related to environmental factors such as temperature and humidity. If the slip ring works in a high-temperature and high-humidity environment for a long time, the wear of the slip ring will be accelerated. Seriously affect its service life and conductive effect
