Problems solved by technology

However, when it is necessary to use the micro-motion table for friction and wear tests with different strokes, it is necessary to replace the cams of different shapes to change the amplitude of the micro-motion table
Since each cam can only correspond to a fixed sliding stroke, the cam driving method, even if the cam can be replaced, the adjustment of the sliding stroke of the micro-motion stage is also step-by-step, and it is impossible to achieve stepless change, which requires gradual adjustment

Abstract

The invention discloses a steel wire micro-kinetic-friction abrasion testing machine which comprises a main rack, and an upper working platform and a lower working platform which are arranged on the main rack, wherein an upper sample steel wire is fixed on the upper working platform, a lower sample steel wire is fixed on the lower working platform, and the upper sample steel wire is in contact with the lower sample steel wire. The steel wire micro-kinetic friction abrasion testing machine also comprises a micro inching displacement frequency regulating mechanism and a micro inching displacement amplitude regulating mechanism, wherein the micro inching displacement frequency regulating mechanism is used for driving the upper working platform to reciprocate relative to the lower working platform so as to form friction between the upper sample steel wire and the lower sample steel wire for carrying out a steel wire friction abrasion test, the micro inching displacement frequency regulating mechanism is also steplessly regulating the reciprocating frequency of the upper working platform, and the micro inching displacement amplitude regulating mechanism is used for steplessly regulating the reciprocating amplitude of the upper working platform.

Description

technical field [0001] The invention relates to friction performance testing, in particular to a steel wire fretting friction and wear testing machine. Background technique [0002] The fretting friction and wear testing machine is a test device used to test and study the parameters related to friction such as hardness, friction performance and wear fatigue performance of materials. Its basic working principle is to drive two surfaces in contact with each other under a certain contact pressure. Slip relative to each other with set amplitude, frequency and contact angle to create friction between the two surfaces, then measure and analyze various friction-related parameters of the materials that make up the two surfaces. [0003] At present, the scheme widely used in the steel wire fretting wear testing machine is to use the cam drive method to generate sliding with predetermined amplitude and frequency between two contacting surfaces, and use the method of pressing weights t...
