Problems solved by technology
These harsh environments make it impossible for a gearbox oil to continuously provide effective lubrication for a long time at four levels throughout the year, so the gearbox of the wind turbine often suffers from broken teeth, pitting and wear on the tooth surface, and fracture of the inner ring gear , Planetary wheel damage and jamming, bearing wear and inner and outer ring running around, etc., causing the gearbox to be removed from the shelf
According to statistics, the failure rate of gearboxes caused by poor lubrication due to insufficient performance of lubricating oil exceeds 82%.

Abstract
The invention relates to an all-season long-acting composite solid lubricant for wind power gearboxes. Polyether (PAG) is used as base oil, polyvinylpyrrolidone (PVP) and hexenyl bisstearamide (EBS) are used as dispersants. The micro-nano solid-phase composite of crystalline fluoride, fluorinated graphite, colloidal molybdenum disulfide, yellow lead oxide and nano-silver powder is dispersed in base oil polyether to form a colloidal composite solid lubricant. The advantage of the present invention is that the synergistic effect between the solid lubricants is formed through the compounding of the solid lubricants on the micron and nanometer scales; The lubricant has excellent anti-wear, anti-friction and extreme pressure properties; through the quantum size effect and surface effect of the micro-nano composite on the liquid-solid interface, the lubrication performance and load-carrying capacity are significantly improved, thereby realizing the application of composite solid lubricants in the field of wind power gearboxes All-season long-term lubrication.
Description
technical field [0001] The invention relates to the technical field of special lubricating grease and solid lubrication engineering, in particular to a composite solid lubricant for wind power gearboxes. Background technique [0002] Wind power gearbox is one of the core components of wind power equipment. Because wind power generators are installed in tuyere places such as mountains, wilderness, beaches, islands, etc., they are subjected to the effect of irregularly changing direction loads and the impact of strong gusts. The effect of temperature difference. These harsh environments make it impossible for a gearbox oil to provide effective lubrication for a long period of time in four grades throughout the year. Therefore, the gearboxes of wind turbines often experience broken gear teeth, tooth surface pitting and wear, and ring gear fractures. , planetary wheel damage and stuck, bearing wear and inner and outer ring running circle and other phenomena, resulting in the re...
