Description

technical field [0001] The invention relates to the technical field of wear-resistant testing, and specifically refers to a constant-temperature and constant-humidity environment wear-resistant test chamber, which is suitable for rapid testing of the wear-resistant performance of mechanical parts materials such as automobile parts under various temperature and humidity environments. Background technique [0002] In the product structure of the automobile glass regulator, the slider carrying the automobile glass slides up and down under the constraint of the guide rail, and a relative sliding friction motion occurs between the slider and the guide rail, which will cause wear on both the slider and the guide rail. How to choose the optimal one? The material of the slider and the surface treatment material of the guide rail are a major difficulty in the design of glass regulator products. It is necessary to design a friction resistance test to compare the selected materials; if...

AI Technical Summary

Problems solved by technology

In the existing wear-resistant test equipment in the market, the driving part generally adopts the screw transmission structure, which is used to drive the test body that needs reciprocating motion. This structure has several disadvantages: 1. The running distance of the material is relatively short, generally only running 100mm Left and right (if the screw is too long, the middle part of the screw will be bent and deformed after being stressed, and the pressure during operation cannot be guaranteed); 2. The running speed is not high, and the linear speed is difficult to exceed 80mm / s, which cannot meet the needs of automotive glass lifting The running speed of the device: 60mm / s~160mm / s; 3. Some electronic components and moving mechanisms in the equipment are difficult to withstand the high temperature and high humidity working environment; only the evaluation and comparison of the wear resistance at room temperature of the material can be completed. Unable to perform tests under high temperature and high humidity environment

However, the wear resistance of many non-metallic materials does not change linearly under different temperature and humidity environments, so it is necessary to evaluate the wear resistance of materials in different temperature ranges and different humidity environments; 4. Test pieces A single movement stroke is only about 100mm, while most automotive window regulators have a single movement stroke of 400mm to 550mm, and the distance of a single movement needs to be achieved by reciprocating 4 to 5 times of the test piece; the test piece is in the test process. Wear powder will be produced, and these powders will participate in the friction test. This test method is equivalent to the cumulative number of cycles of forward and reverse friction of two test pieces in a short distance, which is different from the actual working state of the part. The amount of wear is different from the actual working state
