Ring-block friction wear testing machine

Abstract

A ring-block friction wear testing machine comprises a machine body, a power driving device, a main shaft, a ring-block friction pair and a radial loading device, wherein a test ring in the ring-blockfriction pair is mounted on the main shaft; the power driving device drives the main shaft to drive the test ring to rotate; a force measuring device is arranged between the radial loading device andthe ring-block friction pair; the force measuring device mainly comprises a sample holder, a tension sensor, a hinge rod and a pull rod holder which are sequentially connected; the hinge rod is rotationally connected with the pull rod holder; the pull rod holder is fixed to the machine body; a test sample is mounted at the lower part of the sample holder; the test sample contacts with the test ring to form the ring-block friction pair; a medium channel for providing different lubricating media for the ring-block friction pair is formed in the sample holder; a loading end of the radial loadingdevice acts on the sample holder to perform radial loading and quantitative adjustment on the ring-block friction pair. The ring-block friction wear testing machine can accurately measure friction ofthe ring-block friction pair in real time, and can accurately simulate friction pair lubricating conditions under various actual working conditions.

Description

technical field [0001] The invention belongs to the field of testing machine design and application, in particular to a testing machine for ring-block friction and wear tests. Background technique [0002] The testing machine is a special machine that verifies the quality or performance of products or materials according to the design requirements. There are different types of testing machines depending on the test objects and test items. Ring-block friction and wear testing machine is a commonly used testing machine. [0003] At present, the main structures of ring-block friction and wear testing machines are mostly the same, and most of them cannot achieve accurate quantitative loading of radial force and accurate detection of friction force, and can provide a single form of friction. For example, the patent publication number is CN105158100A "Abrasion Gap Adjustment Type Ring Block Friction and Wear Tester", the radial force loading method adopted is purely manual loadi...

For example, the patent publication number is CN105158100A "Abrasion Gap Adjustment Type Ring Block Friction and Wear Tester", the radial force loading method adopted is purely manual loading, and there is no accurate detection equipment suitable for the loaded radial force , it is impossible to complete the precise quantitative loading of the radial force of the test piece; the lubrication method adopted by the friction pair is fixed, which cannot accurately simulate the lubrication conditions of the friction pair under various actual working conditions. The friction detection method is relatively simple and cannot Accurate measurement of friction
