What are the lubrication methods of plain bearings?
The material is divided into lubricating oil lubrication, solid lubricating grease and Jiaxing Solid Lubricating Bearing Co. Ltd production of self lubricating sliding bearing; the oil supply is continuous oil supply and intermittent supply, intermittent supply by pot filling and brought through the needle valve cup oil grease with only intermittent supply. Continuous oil supply can be divided into oil for oil and oil ring core dam, oil pressure.
(3) solid lubricant. Commonly used solid lubricants are graphite, molybdenum sulfide, Teflon and so on. Usually, the solid lubricant is balanced and lubricated, and the 1. is made by the state, and it is also treated by grinding, sintering, pouring and pulling the friction table. The di green will be molded into the bearing and used in the bearing. Chongqing automotive parts mentioned that solid lubricants can form a solid film on a friction table to reduce frictional resistance. They are usually used in situations where special applications such as vacuum, high temperature, etc. are applied.
Many types of sliding bearing, manufacturing materials, credit conditions and the important degree of difference, so the lubricant requirements vary, the Chongqing auto parts of sliding bearings commonly used lubricants are briefly reviewed. (1) lubricating oil. Lubricating oil is the most widely used lubricant in sliding bearings, and most of the lubricants currently used are mineral oils. The main indexes of lubricating oil are viscosity, oiliness, extreme pressure, chemical stability, etc. when selecting lubricating oil, speed, load and working condition should be taken into account. For large load, high temperature bearings, it is better to choose lubricating oil with high viscosity, small load and high speed bearing, it is better to choose less viscous lubricating oil. (2) grease. Grease is a mixture of lubricating oils and various thickening agents (such as calcium, sodium, aluminum and other metal soaps). Grease is used to form a film that separates the sliding surface. Grease seal is simple, do not need to add often, not easy to drain. But grease is easy to change, friction loss, no cooling effect, it is often used for those who are not demanding, difficult to often oil, or low speed, heavy load and not often used.
