Title:
HIGH-SPEED HIGH-CURRENT SLIDING CURRENT-CARRYING FRICTION WEAR TESTING MACHINE AND TESTING METHOD
Document Type and Number:
WIPO Patent Application WO/2024/016636
Kind Code:
A1
Abstract:
Disclosed are a high-speed high-current sliding current-carrying friction wear testing machine and a testing method, comprising: a driving apparatus and a loading apparatus, an output end of the driving apparatus having a first sample connected thereto, and the loading apparatus having a second sample mounted thereon; the loading apparatus driving the second sample to ascend and descend, and the first sample and second sample coming into contact and forming a friction pair; and the driving apparatus and the loading apparatus acting in concert to cause the second sample to produce various friction tracks on the surface of the first sample. According to the invention, a joint bearing is mounted on the outside of a conductive copper shaft, and a conductive lubricant is added between the joint bearing and the conductive copper shaft, thereby having the effects of lubricating, enhancing conductivity, supporting, compensating angle deviation, inhibiting high-speed circular runout, and ensuring thermal expansion space; during the testing process, a laser displacement sensor continuously monitors the position of a rotating transverse beam; when abrasion causes eccentric wear to a friction pair surface, an X-axis displacement platform actively compensates the direction of a disc sample, so that the end faces of the friction pair are kept in close contact, reducing high temperature and ablation damage caused by electric arcs.
