description: The electric motor is an important part of the trolleybus, and the wear of the rolling bearing in the electric motor causes the equipment to fail easily, therefore, for this task, this paper compares and analyzes the base grease MS 5123-2 and the addition of copper powder with a size of 45 microns and various concentrations (base oil tribological test results + copper powder particles) to control its tribological characteristics to reduce wear problems during equipment operation. In this article, microcopper powder is used as a lubricating additive as an object of study, and the effect of different microcopper powder content and different loads on the friction and wear characteristics of lubricating oil is compared and analyzed by a four-ball machine. The surface morphology of the wear scar under the above conditions was analyzed using an electron microscope and the anti-wear and anti-friction effect of micron copper powder was studied. (1) The test results of the friction and wear characteristics show that: The wear rate (I) of the balls (made of ShKh15 steel) in a 10 second test in lubrication with the addition of copper flake powder with a concentration of 0.5 and 1.0% turned out to be 2 .1192 10-7 and 1.2037 10-7, respectively, which, compared with the base PSM (I = 2.2489 10-7), turned out to be 1.1 and 1.9 times less, respectively. ) balls (made of ShKh15 steel) during a 1-hour test in lubrication with the addition of copper flake powder with a concentration of 0.5 and 1.0%, turned out to be 0.697 and 0.525 mm, respectively, which is compared with the base PSM (Di = 1 .03 mm) turned out to be 1.5 and 2.0 times smaller, respectively. (2) The results of microscopic analysis of the wear scar surface show that the anti-wear and anti-friction effect of nano/sub-micron copper as a lubricating additive is very obvious, the main reason is that nano/sub-micron copper powder is in the lubricating oil. In the process, it plays a role " ball" and optimization of surface polishing.
