Description

technical field [0001] The invention relates to a friction and wear test device, in particular to a vacuum high temperature and high speed friction and wear test device. Background technique [0002] In modern industry, the economic loss caused by wear and tear is very alarming, and with the advancement of science and technology and the development of industrial level, the working environment of mechanical parts is becoming more and more complex, such as high temperature environment, vacuum environment and high speed environment, etc., which makes about One-third to one-half of energy is consumed in friction and wear in various forms, and 80% of mechanical parts fail due to friction and wear. Therefore, the study of friction and wear between parts is very important for saving power energy and material information. very important.

Problems solved by technology

[0003] For the traditional friction and wear testing machine, the test speed is mostly in the range of 0-100m / s. It has no vacuum atmosphere and cannot simulate the friction and wear experiment at different temperatures, and cannot well simulate the daily working conditions between parts. The friction characteristics during high-speed operation cannot meet the requirements of use; and because there are no protective measures when recovering the friction samples of the friction pair, the friction samples flying out of the friction pair at high speed are usually very dangerous. great security risk
