Abstract

The invention discloses a device for measuring the friction behavior of materials under multi-atmosphere and vacuum environments, which comprises a base, a drive unit, a sample clamping mechanism, a pressure head control mechanism and a seal cover, wherein the seal cover is arranged on the base and seals the sample clamping mechanism and the pressure head control mechanism; the sample clamping mechanism comprises a sample stage, a sample gland and a vertical rotating shaft; a sample is clamped between the sample stage and the sample gland; the sample stage is connected with the base through the vertical rotating shaft; the drive unit is dynamically connected with the vertical rotating shaft, and drives the sample clamping mechanism to rotate along the axial line in the vertical direction; and the pressure head control mechanism controls the operating position and the operating pressure of a pressure head, and transmits acquired data to a computing system through a data acquisition device. The device for measuring the friction behavior of the materials under the vacuum environment can realize real-time data acquisition of parameters such as the friction coefficient and so on under a plurality of environments according to the experimental demands, has a simple structure, and is convenient to use.

Description

technical field [0001] The invention relates to a device for measuring the friction and wear behavior of materials in various gas environments and vacuum environments. Background technique [0002] In addition to the conventional friction environment such as normal temperature and normal pressure atmospheric environment, mechanical parts also serve in special environments, such as vacuum environment, oxidizing environment, humid environment, etc., and the friction of materials in different environments There are huge differences in behavior, and ordinary friction test devices cannot meet the research requirements, so it is very important to invent a device for studying the friction behavior of materials in special environments. Contents of the invention [0003] In view of the above problems, the present invention provides a device capable of measuring the friction and wear behavior of materials in a vacuum environment and in various atmospheres. [0004] In order to achi...
