Problems solved by technology

[0003] There are two main methods to change the oil-collecting capacity of the surface of the material. One is to change the microstructure of the material surface, and the other is to replace the traditional material with a porous material. The purpose of these two methods is to use the pores on the surface of the material to store oil. During the lubrication process, The stored lubricating oil can be released to participate in lubrication. The research of the first method focuses on the processing of holes on the material surface, such as the processing of surface texture, which realizes the concentration of lubricating oil and improves lubrication. However, due to the destruction of the friction pair The surface is prone to fatigue damage to parts. The second method has been applied in the design of aerospace equipment, but with the extension of space mission time, the fatigue life of porous materials is also challenged. For the two methods The disadvantage of research is that the surface integrity of the material is destroyed, and the material is easily damaged. Therefore, a self-collecting oil-reinforced raceway surface and its preparation method are designed, and the surface integrity of the material is not destroyed. Enhance the return flow of lubricating oil, which can effectively reduce friction and reduce wear

Embodiment 1

[0031] The main structure of the surface of the self-oil-collecting enhanced raceway involved in this embodiment is: a coating layer 101 and an oleophilic layer 102. The oleophilic layer 102 is located in the middle of the raceway. The width of 101 is 4mm-10mm, the thickness is 80-100nm, and the width of the middle lipophilic layer 102 is 0.3mm-1mm. The material of the coating layer 101 is an organosilane material containing fluorine. Under the action of surface tension, the lubricating oil has a tendency to flow to the center, which ensures effective lubrication improvement even when the remaining amount of lubricating oil is small.

[0032] The surface of the above-mentioned self-collecting enhanced raceway is prepared by a cylindrical roller pressure coating device. The main structure of the cylindrical roller pressure coating device includes: a magnetic base 1, a connecting plate 2, a support column 3, and a compression screw 4 , support plate 5, translation platform 6, ti...

[0044] In this example, the performance of the self-collecting enhanced raceway surface is tested, and the base lubricating oil (PAO4) is used to measure the lubricated raceway width, the oil pool inlet distance and the film thickness under a fixed load condition, and then the pattern wettability is obtained. For the effect of self-collecting oil on the raceway, the specific experimental steps involved in self-collecting oil to enhance the surface of the raceway are as follows:

[0045] (1) Add 1 μl of lubricating oil to the lipophilic raceway in the middle of the self-collecting raceway, use a 25.4mm steel ball and a 150mm glass disc, and light sources with wavelengths of 655nm and 532nm to irradiate between the glass disc and the steel ball to form Interference fringes, keep the load constant, change the speed u to conduct experiments, measure the width of the oil pool, the distance from the entrance of the oil pool and the thickness of the central oil film;

Description

Technical field: [0001] The invention belongs to the technical field of metal surface lubrication, and relates to a self-oil-collecting enhanced raceway surface and a preparation method thereof, which can enhance the backflow of lubricating oil, prevent lubricant creep, and improve the self-oil-collecting performance of friction pairs. Background technique: [0002] The transmission of motion between machines is inseparable from friction, and the wear caused by friction cannot be ignored. While using friction, it is also necessary to reduce the wear caused by friction, and improve the friction state of the friction pair to reduce the wear caused by friction resistance. It is the key. Lubricants are generally used to achieve the purpose of lubricating and reducing wear. In addition, lubricants also have functions such as rust prevention, vibration reduction, sealing, and power transmission. Making full use of modern lubrication technology can significantly improve the performa...
