Problems solved by technology

[0002] In mechanical design, problems such as friction, wear and lubrication are often improperly handled, resulting in huge waste. Therefore, reducing the friction between the surfaces of moving pairs is of great significance for saving resources and prolonging the life of parts; as an advanced lubrication Technology, oil-air lubrication technology has gradually replaced traditional lubrication technology, and is widely used in metal cutting, high-speed heavy-duty bearings and lubrication of friction pair motion under harsh working conditions; the main manifestations of lubrication effect are oil film thickness, oil film shape, oil film Temperature, etc., among which the thickness of the oil film is an important criterion to measure the quality of the lubrication state. Since the thickness of the oil film formed under the condition of oil-air lubrication is relatively thin and the flow speed is relatively fast, it is necessary to accurately obtain the shape and thickness of the dynamic oil film to study the flow characteristics of the oil film. The key point is that most of the existing methods for measuring the parameters of the oil film flow characteristics are contact-type, so that the local area of ​​the oil film is disturbed during the experiment, and it is difficult to obtain more accurate measurement results; the oil film flow characteristics are affected by many factors , in which oil and gas supply parameters, wall microstructure characteristics, experimental wall temperature and vibration have a great influence on the oil film flow characteristics, which cannot be avoided in the actual experimental process;

[0003] In recent years, there has been little research on the flow characteristics of the oil film under the influence of the above-mentioned various factors, and the existing experimental research cannot fully describe the flow characteristics of the oil film. Based on this, the present invention designs an Experimental measurement device with flow to solve the above problems
