Problems solved by technology

[0002] No matter the existing friction and wear testing machine is a reciprocating testing machine or a rotating testing machine, only a single friction and wear test can be performed. When two kinds of friction and wear tests are required, two testing machines must be set accordingly. Not only increases the equipment investment, but also increases the space occupied by the equipment, but also makes the whole experimental process cumbersome and lengthy, increasing the workload of the experimenters

Embodiment Construction

[0026] Such as figure 1 Shown is a schematic diagram of reciprocating friction, the upper sample 1 is fixed, and the lower sample 2 is reciprocating horizontally. figure 2 It is a schematic diagram of rotating friction. The upper sample 3 is fixed, and the lower sample 4 rotates. A certain normal load N is applied to the upper sample 1 and the upper sample 3. The friction force F is generated during friction, and its magnitude is determined by F =N*f, f is the friction coefficient. Under the same working condition, the measured results of different pairs of friction pairs are comparable. The so-called "same working condition" refers to the same friction mode, the same Normal load, same speed, same stroke, same lubrication conditions.

[0027] Such as image 3 , the first experimental machine shown in Fig. 4, the whole experimental machine is made up of base 10, reciprocating mechanism, rotary mechanism and upper sample control device, wherein reciprocating mechanism is comp...

Abstract

This invention discloses two kinds of friction wearing testing machine of integration of reciprocating and rotating, which comprises base socket , reciprocating structure, rotating structure and upper-specimen control device, wherein, the reciprocating structure comprises reciprocating motor, slide block, slide rail, crank, connecting bar; and the rotating structure comprises rotating drive motor and rotating disc; and the upper-specimen control device comprises spring arm, guide rail and slide holder or spring arm , rotating parts and base socket. This invention integrates the reciprocating structure friction wearing machine and rotating friction wearing machine into one structure through special designed base socket and upper-specimen control device and it needn't disassembly specimen and ensures the accuracy of the experience data.

Description

technical field [0001] The invention relates to a friction and wear testing machine, in particular to a reciprocating and rotating integrated friction and wearing testing machine. Background technique [0002] No matter the existing friction and wear testing machine is a reciprocating testing machine or a rotating testing machine, only a single friction and wear test can be performed. When two kinds of friction and wear tests are required, two testing machines must be set accordingly. It not only increases the equipment investment, but also increases the space occupied by the equipment, and also makes the whole experimental process cumbersome and lengthy, increasing the workload of the experimenters. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a reciprocating and rotating integrated friction and wear testing machine that can perform two kinds of friction and wear experiments on the same...
