Wear gap adjustment ring block friction and wear testing machine

Abstract

A ring block friction and wear testing machine with wear gap adjustment solves the problem that the existing friction and wear machines cannot realize the loading and gap adjustment of the test ring and the test block on the same testing machine. It includes a machine base, a power and transmission mechanism fixed on the machine base, a material box provided with a loading mechanism and a testing mechanism, and a measurement control circuit. The technical points are: the loading mechanism includes an adjustment rod, a handle, a fine-tuning dial, a fixed seat, a guide seat with a fixture and a guide rail, the stud section of the adjustment rod matches the threaded hole of the material box to form a spiral pair, and the adjustment rod A handle is fixed on the top, and the handle can be rotated to achieve quantitative vertical loading and precise adjustment of the gap between the test block and the test ring, and it is fixed by a fixing device. It has reasonable design, simple structure compared with existing similar products, convenient loading and unloading of test ring and rubber test block, stable operation, easy gap adjustment operation, accurate spacing, and further improves the reliability of test results consistent with actual working conditions.

Description

technical field [0001] The invention relates to a friction and wear testing machine, in particular to a wear gap adjustment ring block friction and wear testing machine for researching the tribological properties of rubber test blocks and metal test rings in a liquid medium containing solid particles. It can be used for the friction and wear test of rubber test block and metal test ring pair under dry friction, and can also be used for the friction and wear test of metal test ring and metal test block pair under liquid medium containing solid particles or dry friction. Background technique [0002] At present, liquid conveying equipment composed of rubber / metal pairs is widely used in crude oil mining and mine drilling, such as the metal rotor and rubber stator in the submersible screw pump, the rubber bushing and the metal screw of the screw mixed pump. With vice and so on. In the actual use process, the rubber bushing material is not only squeezed and sheared by solid par...
