Abstract

The invention discloses a rotary reciprocating friction testing machine which comprises a base, a plurality of vertical guide rods, a lifting driving mechanism, a voice coil motor and a rotating mechanism are arranged on the base, a lifting mechanism is movably arranged on the vertical guide rods, and the lifting mechanism is in transmission connection with the lifting driving mechanism through threads. A grinding pair fixing device is arranged on the lifting mechanism, a reciprocating test bench is arranged above the rotating mechanism in a clearance mode, the reciprocating test bench is detachably arranged on the base, and the voice coil motor is in transmission connection with the reciprocating test bench. The reciprocating test bed can be quickly disassembled, so that the rotary reciprocating friction testing machine can be conveniently switched between a rotation test and a reciprocating friction test.

Description

technical field [0001] The invention relates to the field of friction experiments, in particular to a rotary reciprocating friction testing machine. Background technique [0002] In all kinds of machinery, the mutual motion between workpieces will inevitably lead to friction and wear, which will lead to the reduction of the life of the equipment or even failure. It is increasingly necessary to study the consequences of friction and wear. In this process, the friction and wear testing machine that simulates the actual working conditions needs to have more functions to make the test closer to the actual wear behavior. [0003] At present, the functions and test conditions of the existing friction and wear testing machines are relatively simple. [0004] A pin-on-disk friction testing machine (CN207379898U) is provided with a friction disc and a friction pin for performing a friction test on the table of the test bench; the friction disc is driven to rotate by a drive device a...
