Abstract
Description
Technical Field
[0001] This application relates to the technical field of conductive rings, and more particularly to a device for testing the high and low temperature performance of conductive rings. Background Technology
[0002] Conductive rings, also known as slip rings, current collectors, or current collectors, are insulated copper or steel rings mounted on the shaft of a motor. They fall under the category of electrical contact sliding connections and are precision power transmission devices that enable the transmission of image, data signals, and power between two relatively rotating mechanisms.
[0003] Based on the conductivity of current, the ring structure allows current to flow freely within the device when it passes through a conductive ring made of a highly conductive metal material (such as copper, aluminum, or silver). Its design typically includes a central hole through which the conductor can rotate or move without affecting the electrical connection outside the ring, thus providing a seamless electrical connection in applications requiring rotation or movement.
[0004] Conductive rings require high and low temperature performance testing during production. The purpose of this testing is to adapt to different ambient temperatures, ensure stable material properties, guarantee reliable electrical performance, simulate actual working conditions, and comply with industry standards and specifications. During the testing process, the temperature control inside the test chamber is sometimes unstable and the temperature uniformity is poor, which has a significant impact on the test results. Furthermore, high and low temperatures affect the performance of the lubricant. High temperatures reduce the viscosity of the lubricant and accelerate its evaporation, while low temperatures cause the lubricant to solidify or thicken, leading to increased friction and wear of the conductive ring, and even jamming. Therefore, it is necessary to continuously add lubricant to the conductive ring during high and low temperature performance testing. Utility Model Content

[0035] The test chamber 111 is equipped with a temperature control mechanism 4. The temperature control mechanism 4 includes a support part 41 located inside the test chamber 111. The support part 41 includes a support box 411 fixedly located inside the test chamber 111, a filter screen 412 fixedly located on the support box 411, and a conductive ring body 413 located on the filter screen 412. The conductive ring body 413 is placed in conjunction with the lubrication pipe 322. The support box 411 is used to hold excess lubricant. The corresponding lubrication points of the conductive ring body 413 (such as oil holes in bearings or clearances in rotating parts) are placed below the lubrication pipe 322. The conductive ring body 413 is connected to the corresponding test equipment to make the rotor rotate, thereby measuring the effect of high and low temperatures on performance.
