Background

In order to meet the lubricating requirements under the harsh conditions of high bearing, heavy load, high torque, ultra high speed, equipment safety, energy conservation, low emission and the like, advanced lubricating technologies need to be developed from small lubrication of various bearings to large lubrication of various large-scale and ultra-large-scale engineering machinery. The lubricating material can be divided into fluid lubrication and solid lubrication according to the form of the lubricating material, wherein the former is used for changing the boundary lubrication state of an adsorption film formed on a metal surface, and the latter is used for reducing the friction and the abrasion of two surfaces which move relatively by utilizing solid powder, a film or a whole material and protecting the surfaces from being damaged. The fluid lubrication has the advantages of low friction coefficient, good heat conduction performance, less abrasive dust, good self-repairing performance and the like. The defect is that the device is difficult to be used in special working conditions such as high and low temperature, high vacuum, strong radiation and the like; the weight and volume caused by the need for strict sealing and storage; the fat-supplementing period is too short and the fat-adding amount is too large. The solid lubrication has the advantages of capability of adapting to various severe working conditions, light weight, small volume and low cost. The disadvantages are large friction coefficient, much abrasive dust, difficult heat conduction, short service life of lubricating film and the like.
