Description
Technical Field
The invention relates to a circular ring type photoelastic flow oil film measuring tester, in particular to a measuring tester for the thickness and the shape of a cylindrical roller line contact elastic flow lubricating oil film under a high-speed oil lacking condition.
Background
In the modern mechanical industry, the failure of mechanical parts such as bearings, gears and the like is often caused by the failure of elastohydrodynamic lubrication. Particularly, with the progress of modern technology, bearings, gears and the like are continuously developed in the high-speed direction, and the oil-lacking phenomenon is more and more. Therefore, theoretical and experimental research is carried out on the elastohydrodynamic lubrication under the high-speed oil-lacking condition, and the explanation of the factors influencing the elastohydrodynamic lubrication is of great significance.
Determining the geometry and thickness of the oil film in the contact zone is one of the most important issues in elastohydrodynamic lubrication research, since the thickness of the oil film determines the proximity of the asperities on the surfaces of relative motion, thereby playing a dominant role in friction, wear and fatigue failure of the system. As a method for measuring the film thickness of the contact region, there are a resistance method, a capacitance method, a magnetoresistance method, a displacement method, an X-ray method, and the like, in addition to the optical interference method.
Among the technologies for measuring the thickness of the elastic flow film, the resistance method is the earliest technology, but as research work is further carried out, the resistance method is gradually found to be only capable of measuring whether the oil film exists in a contact area and not capable of measuring the thickness. The principle of capacitance method measurement is similar to that of resistance method, and the capacitance method can judge the film thickness according to the measured capacitance, but the defect is that the capacitance method measures the average thickness of the oil film, not the actual value of any part. The magneto-resistance method is used for calculating the thickness of an oil film by measuring the current change in a coil caused by the magnetic flux passing through the oil film, and the measuring method is easily interfered by the outside. The displacement method is a method for indirectly determining the thickness of an oil film by measuring ultimate displacement, and depends on the accuracy degree of a displacement sensor, the lowest detection limit of the current displacement sensor is 0.1 micrometer, and the thickness of the oil film is usually less than 0.1 micrometer, so that the displacement method has great limitation. The X-ray method measures the thickness of the lubricant film according to the difference of penetrating power of X-rays to metal and oil, but long-term research shows that the X-ray method is difficult to calibrate and can only measure the minimum value of the thickness of the oil film generally.
The shape of the film thickness at the bullet-stream contact position measured by the optical interference method is a relatively new technology adopted in the 60 th century. In recent years, researchers have paid more and more attention to continuous improvement of optical interference measurement devices and techniques. The optical interference method is simple in principle and easy to implement, and can simultaneously measure the thickness of an oil film and the shape of the oil film in a contact area. The precision of the optical interferometry, which is the most important means for measuring the film thickness, is about 1 nm. Although optical interferometry is well accepted, there are relatively few types of optical interference oil film measurement devices. At present, the line contact optical interference oil film measuring device is basically divided into two types, the first type is a disc type optical interference measuring device, the disc type optical interference measuring device can only measure a tapered roller serving as a tested piece, the measuring device has certain limitation on the taper and the length of the roller, and the line contact oil film thickness of the cylindrical roller cannot be measured. The other type is a linear reciprocating type optical interference experiment table, although the experiment table can measure the cylindrical roller, the experiment table can only run at low speed due to the characteristic of reciprocating motion, and has certain limitation.
