Abstract

The invention provides a variable load contact lubrication and wear integrated test machine, specifically, a roller and a glass block or a steel block can form a long / short finite length contact under variable load conditions, and the glass block or steel block can be indirectly driven by a motor. The block makes reciprocating linear motion with a certain rule and uses the speed sensor to feed back the moving speed of the glass block or steel block in real time. The shape and thickness of the elastohydrodynamic lubricating oil film formed by the roller and the glass block can be observed and stored in real time, or the roller can be studied. Variable load long / short finite length contact lubrication wear integrated machine with wear between steel blocks. The invention has the advantages of simple structure, strong practicability and reliable operation, and provides a reliable test device for studying the lubrication or wear problem of long / short finite-length contact under variable load conditions.

Description

technical field [0001] The invention relates to an integrated test machine for contact lubrication and wear with variable loads, in particular to an integrated test machine for optical elastic hydrodynamic lubrication and wear for studying the problem of long / short finite-length contact under variable load conditions. Background technique [0002] A finite length of contact of varying lengths is formed between the sleeve and the pin of an industrial chain, resulting in elastohydrodynamic lubrication or wear. In the existing optical elastohydrodynamic lubrication and wear testing machines, glass discs or steel discs are generally driven to make circular motions, so only point contact or small-sized surface contact experiments can be carried out; use this test machine for finite-length contact During the experiment, the linear velocity of different positions in the direction of the roller axis will be different, and the finite-length contact problem cannot be accurately and ef...
