Description

technical field [0001] The invention relates to the technical field of impact and wear testing machines, in particular to a small-load impact and wear testing machine with tangential velocity. Background technique [0002] Among various wear failures in engineering tests, impact wear is a relatively common situation, but it is the least understood type of wear. Impact wear, also known as impact wear, is the damage caused by one object (repeatedly) impacting the surface of another object. [0003] As we all know, there are few simple impact loads in actual working conditions. The impact is often accompanied by the relative motion of two impacting objects, and the direction of this motion is always perpendicular to the direction of the impact motion. The inner and outer rings will produce impact, and they themselves have a tangential velocity. Therefore, it is of great practical significance to establish a small load impact wear tester with a tangential velocity. [0004] Th...
