Problems solved by technology

[0003] Most of the existing friction and wear testing machines can only evaluate the tribological behavior under pure sliding or pure rolling conditions, and it is difficult to truly evaluate the wear behavior and wear mechanism of the above moving parts under actual working conditions

Embodiment 1

[0035] In this embodiment, the material to be evaluated is styrene-butadiene rubber for tires, its carbon black model is N220, and the opposite grinding material is a grinding wheel. The method for evaluating the wear behavior of styrene-butadiene rubber for tires is as follows:

[0036] Such as figure 1 As shown, two independently rotatable rotating wheels are set on the base 1, one is the sample wheel 3 driven by the first motor 7, and the other is the counter grinding wheel 2 driven by the second motor 8. Styrene rubber is cut into long strips and adhered to the surface of the sample wheel. The styrene-butadiene rubber sample should not be subjected to tension during bonding, and the joint should be smoothly transitioned during bonding, and the sample wheel after bonding should be conditioned for at least 16 hours. The pair of grinding wheels is a commercial grinding wheel. The sample wheel is provided with a bracket 5 for loading, and a weight 6 is placed on the bracket ...

Embodiment 2

[0042] The carbon black model of styrene-butadiene rubber for tires to be evaluated in Example 1 was replaced with N330, and other conditions and evaluation methods were exactly the same as in Example 1.

Embodiment 3

[0044] The carbon black model of styrene-butadiene rubber for tires to be evaluated in Example 1 was replaced with N550, and other conditions and evaluation methods were exactly the same as in Example 1.

Abstract

The present invention provides a method for evaluating the wear behavior of a material. According to the method, a material to be evaluated and an opposite wear material are arranged on the surfaces of two independently-rotating rotation wheels to form a friction pair, such that the evaluation of the tribology behavior of the material under the conditions such as pure sliding, pure rolling and different rolling sliding ratios can be achieved by regulating and controlling the rotating speeds of the two rotation wheels, and the applying of different loads between the friction pairs can be achieved by applying loads onto the rotation wheels. With the method of the present invention, the wear behavior and the wear mechanism of the material under the actual working condition can be stimulated, and the method is suitable for the evaluation of the tribological behavior of rubber materials, coatings, films, and other materials.

Description

technical field [0001] The invention relates to the technical field of material friction and wear, in particular to a method and device for evaluating material wear behavior. Background technique [0002] The moving parts in modern equipment have motion states such as rolling and sliding. In actual working conditions, some moving parts are often not a single pure rolling or pure sliding, but a complex motion state of both sliding and rolling. For example, bearings and shaft parts have a combination of rolling and sliding motion in practical applications. In the actual use of automobile tires, due to different use occasions and conditions, there are not only pure sliding and pure rolling, but also a combination of rolling and sliding under a certain rolling-slip ratio. For example, the tires are purely rolling when the car is running at a constant speed, purely sliding under sudden braking, and running with a certain rolling-slip ratio under acceleration or deceleration. ...
