However, the experimental test of low-pair contact sliding bearings is much more difficult than that of high-pair contact sliding bearings, which leads to the fact that the experimental research of low-pair contact sliding bearings lags behind its theoretical research, and correspondingly, theoretical research is difficult to be verified by experiments.
[0003] In the experimental research of sliding bearings, in order to explore its lubrication mechanism, the full bearing is often simplified as figure 1 The slider-plane contact form is shown, and at the same time, using this contact form to explore the balance relationship between lubricating oil film thickness, friction force and load is the focus of optimizing bearing design and reliability, but the existing equipment is limited to a single Lubricating oil film thickness measurement, but can not measure friction and film thickness at the same time

Description
Technical field: [0001] The invention belongs to the field of measurement of tribological characteristics of low surface contact oil film lubrication, and relates to a real-time measurement device for a lower lubricating oil film and friction force in slider-plane contact, in particular to a real-time measuring device for lubricating oil film and friction force of a slider bearing. Background technique: [0002] Sliding bearings based on hydrodynamic lubrication mechanism are widely used in industry due to their advantages of high load capacity, smooth motion, reliability and no noise. However, there are also disadvantages such as large power consumption, low transmission efficiency, and large lubricant consumption. However, modern equipment puts forward new technical requirements for fluid lubricated sliding bearings in terms of reducing energy consumption, improving energy efficiency, reducing emissions, and prolonging equipment life. From the perspective of improving mach...
