Problems solved by technology

However, this testing machine can only be used for friction tests under normal temperature, conventional, and non-lubricated environments.
Neither of the above two testing machines has the function of capturing the instantaneous state of friction pair gluing failure and wear failure during the test; there is no function of simultaneously measuring the temperature, friction force and friction coefficient of the friction pair online; , operating load and other functions

Embodiment

[0023] figure 1 It is an embodiment disclosed by the present invention (see figure 1 ), before the experiment, according to the test requirements, the lower surface of the upper sample 23 to be detected is processed into an inner arc (see Image 6 ), the lower sample 25 is processed into a disk. Install the radial ball bearing 35, the lower sample 25, the lower sample fixture 39 and the cylindrical roller bearing 40 on the support shaft 37, then install the shaft assembly on the bearing housing 36 and the bearing housing 41, and start the motor 32 Adjust the rotating speed, then load, start the lubricating device 31 and the signal collecting device. The frequency conversion motor 32 drives the support shaft 37 to rotate through the torque speed sensor 34, and the support shaft 37 drives the sample 25 to rotate together. According to the test requirements, the lubricating oil flows from the lubrication system 31 and the pipeline 29 to the outer surface of the lower sample 25...

Abstract

The tester comprises: a clamp (22) to fix the upper sample (23) on its arc groove above the lower sample (25) connected to the middle of supporting shaft (37) by a flat key, a oil bath (26) to accommodate part (25), and a pressure bearing (20) with outside circle contacted to the upper arc surface of (22). This invention can protect the failure condition, and cuts wear test time.

Description

technical field [0001] The invention relates to a radial sliding bearing friction and wear testing machine, in particular to a radial sliding bearing friction and wearing testing machine capable of accelerating wear and detecting friction coefficient and temperature on-line. Background technique [0002] At present, there are various general friction and wear testing machines for the measurement of the friction force and friction coefficient of mechanical materials at home and abroad, which can achieve accurate measurement. However, these general-purpose testing machines can only be used to study the friction and wear laws of materials, but cannot directly study the friction coefficient, friction force and friction temperature of actual parts during the friction process. Especially for radial sliding bearings, in different lubrication states (boundary lubrication state and hydrodynamic lubrication state), the test of the tribological properties (friction coefficient, frictio...
