A test device for the abrasion resistance of shoe soles that can simulate various environments

Abstract

A test device for the wear resistance of shoe soles that can simulate various environments, including a test bench base, a friction test device is installed at the front end, two sets of friction test devices are installed at intervals, and the two ends of the test bench base are respectively installed to control their movement drive motor, shaft coupling and torque sensor; a hydraulic pressure device is installed in the middle of the base of the test bench, the output end of the hydraulic pressure device is connected to the foot model device, and the foot model device is located on the top of the friction test device. Through the up and down movement of the transmission roller in the friction device, the discontinuity of the friction belt rubs against the shoes, there is a gap between the two friction belts, and the replaceability of the friction belt. The changeability of the control and foot model can simulate the movement of the foot when people walk; the change of the friction coefficient can be indirectly obtained by using the torque sensor to measure the change of the torque, reflecting the degree of wear and tear, making the obtained data more direct and more accurate .

Description

technical field [0001] The invention relates to the technical field of friction testing mechanical equipment, in particular to a shoe sole wear resistance testing device that can simulate various environments, and can be used to test the wear resistance of shoe soles under various different conditions. Background technique [0002] At present, promoting a two-oriented society, saving resources and protecting the environment are the current priorities. Inappropriate design and selection of sole materials by shoe factories in the shoe production process will easily lead to increased wear of the soles, resulting in the scrapping of shoes, resulting in a great waste of sole material resources. pollute. The aspect of shoe sole performance evaluation can help to solve this problem. Elicit this project or test method. [0003] In the prior art, there are mainly the following deficiencies in the testing device for the wear resistance of the sole: [0004] One is that the test pr...

AI Technical Summary

Problems solved by technology

[0004] One is that the test process only continuously rubs the sole on the friction plate, and cannot better measure the heel and forefoot. It is difficult to simulate the state of people walking and the different degrees of wear on the shoe in different environments, so the obtained sole is wear-resistant. Performance often does not match reality;

[0005] The second is that it is limited to testing two (or even more) shoes at the same time for each test, which leads to a slightly bulky size of the equipment;

[0006] The third is that some equipment adopts the technology of mechanical feet, the structure of the device is complex and the stability is poor, and the price is too expensive;

[0007] Fourth, there is no equipment that can easily measure the coefficient of friction by placing the finished shoes on the testing machine.
