Wear test device and wear test method

Abstract

The invention discloses a wear test device. The wear test device comprises a weight, a driving motor, a grinding wheel arranged on a rotating shaft of the driving motor, and a lever mechanism arranged at one side of the grinding wheel by virtue of a loading shaft as well as a first spraying water pipe arranged above the grinding wheel at one side close to the lever mechanism, wherein the lever mechanism is composed of a cross rod and a vertical rod, a loading rod is arranged below the cross rod, a weight mounting hole is formed in one end of the cross rod far away from the vertical rod, the weight is loaded on the cross rod by virtue of the weight mounting hole, a sample mounting hole is formed in the part, close to the grinding wheel, of the vertical rod, and the sample mounting hole is toward the grinding wheel, a water spraying hole of the first spraying water pipe is toward the grinding wheel, and the lever mechanism is of an L-shaped structure which is composed of the cross rod and the vertical rod in an integrated manner. The wear test device has the characteristics that multiple low stress scratch wear environments are provided, a test result is effective and accurate, test cost is low and maintenance is convenient.

Description

technical field [0001] The invention relates to the technical field of material performance testing and analysis, in particular to a wear test device and a test method. Background technique [0002] Structural parts of mechanical equipment, long-term work in stress wear environment. Before the structural components are put into use, it is necessary to conduct wear resistance tests on the materials used to make them, and to measure the wear resistance of metal materials through wear tests. Among them, the production materials of most structural parts need to undergo low-stress scratch wear resistance tests. Abrasion test includes physical wear test and sample wear test. Since sample wear test has low test cost, it is the main wear test method. In the sample wear test, the wear amount of the sample is proportional to the contact pressure and friction distance, and inversely proportional to the hardness of the material. [0003] Low-stress scratch wear means that the stress o...

Problems solved by technology

[0006] However, this wear testing machine has the following technical problems: the rubber wheel B1 is composed of a circular metal base and a rubber layer attached to the outer ring of the circular metal base. scrapped

[0008] To sum up, in the prior art, when performing low-stress scratch and wear resistance of structural materials, there are technical problems that the rubber wheel B1 needs to be measured frequently, the use of test equipment is more formal, more consumables are used, and the test cost is high.
