Description
Technical field
The present invention relates to wear testing technical field, particularly a kind of abrasion testing device.
Background technology
Wearing and tearing are a kind of fundamental types that parts lost efficacy.On ordinary meaning, wearing and tearing refer to that parts physical dimension (volume) diminishes.The function that parts lose original design defined is called inefficacy.Inefficacy comprise completely lose original function, function reduce and have major injury or hidden danger, continue use can lose reliability and safety and security.Wear testing measures material repels
wearing and tearingthe one of ability
material test.By this test can the wearing quality of comparative material good and bad.First need the specific works condition of consideration parts and determine wear form, then selected suitable test method, to make test findings and actual result comparatively identical.Wear test is divided into on-the-spot wear test and laboratory wear test.On-the-spot wear test is contained on machine by the sample making part, tests under real-world operation condition.And laboratory wear test is that in vitro abrasion tester carries out, shaped and sample that is size is tested.In an experiment, often need the relation between test speed and wearing and tearing, current method of testing utilizes two abrasion testing devices equally to test with different relative velocities two abrasive materials wheels and two test blocks, the difference after test between compare test block.Because no matter appearance or material composition always there are differences taken turns by two abrasive materials, such test result often accuracy is poor.
Summary of the invention
The object of this invention is to provide a kind of abrasion testing device, realize the test to relation between speed and wearing and tearing, structure is simple, and accuracy is good.
