A continuous testing equipment for the abrasion of short fiber radially oriented tread rubber

Abstract

The invention belongs to the technical field of rubber abrasion detection, and relates to a continuous testing equipment for short fiber radial orientation tread rubber abrasion. The main structure includes four parts: grinding mechanism, rotary mechanism, angle adjustment mechanism and electric control box, which is specially suitable for The wear test of short fiber radial orientation tread rubber can adjust the load, speed, wear angle and other experimental parameters according to the needs, and realize the wear test of different speeds, different loads and different angles, so as to truly and effectively reflect the short fiber under different environmental conditions. The wear resistance of radially oriented tread rubber uses the grinding wheel as the driving wheel and the rubber wheel as the driven wheel. When replacing each group of samples, it only needs to be removed and pasted on the rubber wheel without stopping the machine, and continuous testing can be achieved. Type batch test; the equipment is reasonable in structure, scientific in design, easy to operate, safe in use, high in test accuracy and good in test efficiency.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of rubber wear detection, and relates to a rubber wear test device, in particular to a continuous test device for the wear of short fiber radially oriented tread rubber, which is used for short fiber radially oriented tread rubber under different environmental conditions. Under the wear performance test. [0003] Background technique: [0004] Rubber composite material is one of the most used and widely used polymer materials. The reason is that rubber not only has high elasticity, but also has high electrical insulation, low thermal conductivity, excellent air tightness, and water tightness. Some Special rubber also has special properties such as chemical corrosion resistance, high temperature resistance, low temperature resistance, and oil resistance. The short fiber reinforced rubber composite material is a new type of rubber composite material, which combines the rigidity of short fibers and the ...

AI Technical Summary

Problems solved by technology

[0005] The wear process of rubber materials is very complicated. Because its high elasticity is accompanied by many deformations such as stretching, compression, and shearing in actual use, and is affected by parameters such as the roughness of external friction pairs, ambient humidity, and temperature, the The abrasion test of rubber materials is relatively difficult. So far, the common rubber abrasion test equipment in the laboratory includes Akron abrasion test equipment, DIN abrasion tester and Gracili abrasion and other experimental methods. Akron abrasion test equipment is currently used in our country. The most widely used standard rubber abrasion testing machine, the device has a simple structure and is widely used. The sample is subjected to periodic friction, and the contact between the sample and the abrasive is discontinuous, so it can reduce the influence of heat generation during the abrasion process, but the load and The rotating speed is small and cannot be adjusted, and the test conditions are relatively simple; the DIN abrasion testing machine is also called the roller abrasion testing machine. The cylinder is moved laterally to measure the wear volume of the cylindrical sample after a certain stroke. This equipment is easy to operate and has small errors, but it needs to frequently correct the load and replace the sandpaper; the impact of the sandpaper particle size on the wear volume in the Gracili abrasion test equipment is relatively small. However, there is no test equipment or device specially used for the wear of short fiber radially oriented tread rubber in the prior art. Therefore, the present invention researches and designs a kind of wear test specially used for short fiber radially oriented tread rubber. The test equipment realizes the continuous test of wear resistance under the condition that all test conditions can be controlled, which has good practicability and promotion value
