Abstract

The invention discloses a friction and wear test tool. The test tool includes a rotating unit and a load unit. The rotating unit includes a friction disc. There is a mounting hole in the middle, the connecting rod is inserted into the mounting hole, the fastener is slidably set on one end of the connecting rod, and the fastener is fixedly installed in the mounting hole, the spring is set on the connecting rod, and one end of the spring is connected to the connecting rod. The connecting rod is fixedly connected, the other end of the spring is fixedly connected with the fastener, one end of the pin sleeve is fixedly installed on the other end of the connecting rod, the friction pin is fixed on the other end of the pin sleeve, and the friction pin is arranged towards the friction disc. In this embodiment, the friction disc is used to rub on the surface of the friction pin, and the friction pin is given different pressures by different initial compressions of the spring. At the same time, by controlling the different rotational speeds of the friction disc, the friction pairs under different speeds and different loads can be tested finally. friction and wear results.

Description

technical field [0001] The invention belongs to the field of friction and wear tests, in particular to a tool for friction and wear tests. Background technique [0002] A friction pair is a friction system formed by friction between two objects in contact with each other, and a friction pair is a system composed of two objects that are in direct contact and generate relative frictional motion. According to the motion form of the friction pair, it can be divided into a sliding friction pair and a rolling friction pair. The surfaces of the two objects of the sliding friction pair have a tendency to slide or slide relative to each other. When two objects rub against each other, it will inevitably cause friction and wear. Friction and wear are the main factors causing the failure of various mechanical equipment, especially the wear and tear of key parts will directly affect the reliability of the entire equipment, and the most direct impact on friction and wear is The most impo...
