Description

Technical Field

[0001] The utility model relates to the field of lubrication, and particularly to a metal workpiece with a reduced friction coefficient. Background Art

[0002] Lubrication is an essential link between friction pairs during the normal operation of mechanical equipment and the manufacturing and processing of materials. With the rapid development of industry, various lubrication forms have emerged. Starting from oil lubrication and slowly developing to self-lubrication in the later stage, there are various problems such as various contaminations, oil leakage, and grease filling through the form of lubricating oil. It is difficult for self-lubricating materials to meet the design strength requirements of friction structures.

[0003] At present, the Chinese utility model with the publication number CN209195961U discloses a bearing, which relates to the field of bearings. It includes an inner bearing ring and an outer bearing ring sleeved outside the inner bearing ring. A cage is arranged between the inner bearing ring and the outer bearing ring. A number of rolling elements are arranged on the cage. Dust covers are fixedly connected to both ends of the outer bearing ring. Circular through holes are arranged on the dust covers. A circular plate is concentrically arranged in the circular through holes. The upper and lower ends of the circular plate are rotationally connected to the circular through holes through short shafts. The technical problem solved is that it is rather troublesome to add lubricating grease to the inside of the bearing in the prior art. It is necessary to remove the dust cover, with cumbersome operation and low efficiency. The advantage of the utility model is that lubricating grease can be added to the inside of the bearing without removing the dust cover, and it is very convenient to open and close the opening for adding lubricating grease, saving time and improving the efficiency of adding lubricating grease.

[0004] In summary, although the bearing can achieve the function of facilitating the injection of lubricating oil, there are still certain problems in use. First of all, the bearing lacks a structure that can be quickly installed and disassembled. Since the rolling balls of the bearing are installed between the bearing rotating sleeve and the bearing rotating cylinder, grooves for the rolling balls to slide are provided on both the bearing rotating sleeve and the bearing rotating cylinder of the bearing, and the gap between the bearing rotating sleeve and the bearing rotating cylinder is limited. It is rather troublesome and laborious to install the rolling balls. At the same time, although the bearing uses lubricating oil to reduce the friction coefficient, various contaminations and oil leakage will occur through the form of lubricating oil, and it is not environmentally friendly during use. Therefore, we provide a metal workpiece that injects plastic oil to reduce the friction coefficient to solve the above existing problems. Summary of the Utility Model
