Embodiment

[0023] figure 1 It is the disclosed embodiment of the present invention. Before the experiment, the lower surface of the upper sample to be detected is processed into an inner arc by the test requirements (see Image 6 ), process the lower sample into a disc. Install the radial ball bearing, the lower sample, the lower sample fixing part and the cylindrical roller bearing on the support shaft, then install the shaft assembly on the bearing seat 36 and the bearing seat, start the frequency conversion motor to adjust the speed, and then load, Start the lubrication device and signal acquisition device. The frequency conversion motor drives the support shaft to rotate through the first shaft coupling 42, the torque speed sensor, and the second shaft coupling 43, and the support shaft drives the sample to rotate together. According to the test requirements, the lubricating oil flows from the lubrication system and the second pipeline to the outer surface of the lower sample. Afte...

Abstract

The invention discloses an on-line measuring and testing machine for friction and wear of radial sliding bearings. The invention includes driving, loading, testing device and signal acquisition parts, wherein: the upper sample (23) is fixed in the arc groove of the upper sample holder (22), and the upper sample (23) is placed in the lower sample (25), the lower sample (25) is connected with the middle part of the support shaft (37) with a flat key, the lower part of the lower sample (25) is placed in the oil pool (26), and the upper sample holder (22) The upper arc-shaped surface of the upper arc surface is in contact with the outer ring of the pressure bearing (20); the present invention can detect the instantaneous friction and wear process of the surface of the friction pair online; when the glue failure and wear failure are found, the instantaneous friction state is protected by emergency stop; The friction pair materials, lubricating oil and grease lubrication effects are tested and evaluated, and the accelerated friction and wear test can be realized to shorten the 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...
