Abstract

The invention discloses a solid lubricating agent for a hydraulic mechanism. The lubricating agent comprises the following components in parts by mass: 14.3-18.4 parts of graphite, 30.2-38.2 parts ofpolytetrafluoroethylene, 12.0-14.3 parts of brown aluminum oxide, 26.4-28.1 parts of lithium-based grease and 12.3-13.6 parts of molybdenum disulfide, wherein all components are granular and are about200-800 meshes; and the components are fully stirred. The lubricating agent is low in cost, green, environmentally-friendly, low in frictional coefficient (0.04-0.13), convenient to replace and operate, simple in method, high in result transformation potential, extensive in application value, and mainly applicable to lubrication of hydraulic mechanism equipment under high temperature, high humidity and high load environments.

Description

technical field [0001] The invention relates to a solid lubricant, in particular to a solid lubricant for hydraulic machinery. Background technique [0002] Friction and wear occur on the surface of mechanical parts in relative motion, which is a natural phenomenon. The reason why wear is paid attention to by people is mainly because the loss caused by wear failure is astonishing, and a large number of personal casualties are caused at the same time. According to statistics, wear, fracture and corrosion are the three forms of failure of mechanical parts, among which wear failure is the main cause of failure of electromechanical engineering equipment including aviation equipment, and about 70%-80% of equipment damage is due to various forms caused by wear and tear. Therefore, how to solve the problem of reducing friction and lubrication, prolonging the service life of mechanical parts, and reducing production costs is a problem that needs to be solved for a long time in the...
