In this study, the influence of temperature on tribological properties unreinforced or glass-fiber reinforced PA66 in contact with carbon steel under boundary lubrication grease was studied when considering dependence mechanical sliding surface and tribochemical reaction to zinc carboxylate additives grease. XPS ToF-SIMS analyses revealed formation a tribofilm sulfide reactive film surface, whi...

Abstract Lubricating greases are widely used in e.g. open gear drives and gearboxes with difficult sealing conditions. The efficiency heat balance of grease-lubricated depend strongly on the lubrication mechanisms channeling circulating, for which grease flow is causal. computational fluid dynamics opens up possibility to visualize understand more detail. In this study, a single-stage gearbox l...

China’s rapid industrial development requires more energy consumption based on non-renewable resources. The caused by unnecessary friction accounts for about 4.5% of the GDP in China. Although grease effectively lubricates machines, lubrication failure may occur under severe conditions. Nanomaterials exhibit intriguing tribological performances and have received much attention regarding lubrica...

In this paper, film thickness and pressure distribution of EHL in line contacts for four kinds of greases and one type of oil are calculated under a series of rolling velocities by wing an inverse solution method. The Herschel-Bulkley model is wed for the rheological characteristics of the grease. Based on the theoretical analysis and numerical calculation, the following influences on film thic...

Molybdenum disulfide is one of the best known solid lubricants, and although it originally gained popularity in aerospace and military applications, it is now commonly found in a variety of lubrication applications. It is widely used in greases and specialized grease-like products known as pastes, in fluid lubricants such as automotive and industrial gear oils, in solid film lubricants includin...
