Problems solved by technology

[0005] The purpose of the present invention is to make up for the deficiency that the current reciprocating friction and wear testing machine cannot test multiple pads at the same time. The double-station structure design achieves the comparative friction and wear test of different pad materials under the same working conditions at the same time. The variable is minimized; in addition, the opposed reciprocating structure is adopted to solve the problem of excessive vibration caused by the large inertial force of the current testing machine during the high-frequency test of the moving mechanism during work. Therefore, a reciprocating double Station friction and wear testing machine, to achieve the purpose of reducing mechanism vibration and double-station comparison test

Abstract

The invention relates to a reciprocating double-station friction-wear tester which comprises a tester base, a driving system, a loading system, a friction testing system and an abrasion testing system, wherein the driving system is fixed on the base; a driving gear is driven by a speed adjusting motor to rotate, and driven gears are driven by the driving gear to work, so that moving plates can be driven by a slider-crank mechanism to make straight line reciprocation movement. The tester is based on the idea of a symmetric mechanism, two driven gears in opposite rotation directions are adopted to drive the moving plates to make straight line reciprocation movement in opposite directions, and inertia force generated when each moving plate is moved can be just counteracted. The reciprocating double-station friction-wear tester is capable of simulating abrasion and wearing properties of a self-lubricated joint bearing liner in different working environments, is very good in working consistency, and can provide very wide working condition options.

Description

technical field [0001] The invention relates to a reciprocating double-station friction and wear testing machine. Background technique [0002] There is friction between the relatively moving parts of most mechanical equipment, and most of the friction is unfavorable to the operation of the machine. Friction can cause excessive loss of energy and failure of mechanical equipment. In addition to direct economic losses, it can easily cause other hazards. Therefore, it is of great significance to carry out experiments and research related to tribology in reducing energy loss, improving production efficiency, protecting the environment, reducing equipment damage and safety accidents. The friction and wear performance of parts in mechanical equipment is determined by factors such as materials, working conditions, contact methods, and environmental conditions. To correctly evaluate the influence of various factors on the friction and wear performance, it is usually necessary to u...
