Abstract

The invention discloses a zero-entrainment friction and wear testing machine which comprises a base, a first movement system, a second movement system and a driving system. The base is provided with an upper table facet 3 and a lower bottom plate 1; the second movement system is fixedly connected with the base; the first movement system is fixedly connected to an operation panel 46; the operation panel 46 is connected with the base in a sliding manner; the driving system is respectively connected with the base and the operation panel 46 and is used for driving relative motion between the operation panel 46 and the base. The zero-entrainment friction and wear testing machine disclosed by the invention has the advantages of simple structure, high disk use rate, high wear resistance, low cost, high accuracy, high stability and the like.

Description

technical field [0001] The invention relates to the technical field of friction and wear testing machines, in particular to a zero-entrainment friction and wear testing machine. Background technique [0002] There is friction between the relative moving parts of the current mechanical equipment, and the abnormal friction and wear caused by improper lubrication will not only affect people's production activities, but also cause a huge waste of social wealth. In order to study the phenomenon of friction and wear and its essence, and to correctly evaluate the influence of materials and environment on friction and wear, the friction and wear testing machine is an indispensable test equipment. [0003] The zero-entrainment condition is the case where the average velocity of the two solid surfaces is equal to zero, or the slip-roll ratio is equal to infinity, for example, two zero-entrainment conditions may occur in one cycle of the cam-tappet pair lubrication system, or Cageless...
