Abstract

The invention discloses a rubber abrasion testing device, which comprises a main body of an abrasion machine, a temperature adjustment device, an angle adjustment device and a temperature measurement device, wherein the main body of the abrasion machine is divided into a driving system A and a driven system B, and the driving system A is assembled on On the motor base, the driven system B is directly installed on the base through bolts. The driving system A includes an adjustable speed motor, a speed controller and a grinding wheel, and the driven system B includes a loading lever, a weight, a bracket and a sample rubber wheel. The invention can adjust the temperature, speed, load, wear angle, etc. in the wear test, so as to realize the wear test of different speeds, different loads and different angles, and can fully simulate various actual service conditions of the tire. It overcomes the defect that the test temperature, load and rotational speed of the Akron abrasion machine are fixed values ​​and are all smaller than the actual value of the tire. Experimental results show that the invention can better reflect the real wear resistance of rubber tires under different environmental conditions.

Description

technical field [0001] The invention relates to the technical field of rubber wear detection, and belongs to rubber wear test equipment, which is particularly suitable for testing the wear performance of rubber under different environmental conditions. Background technique [0002] The wear resistance of the tire tread is one of the important indicators to measure the service life of the tire, and it is a must-check item in every tire factory. At present, the Akron wear machine is a commonly used wear testing equipment. However, the experimental data of the Akron abrasion machine in each tire factory is mainly used to test the stability of the tread formula and the mixing process, etc., but it is not used much in evaluating the actual wear resistance of the tire. This is mainly due to the large difference between the experimental conditions of the Akron abrasion machine and the actual road conditions of the tires, resulting in a weak correlation between the test data of the...
