Composite oil composition for film bearing

Abstract

The composite compound for oil-film bearing oil comprises following constituents: 0.01-1.0% any one or mixture of condenses of amine and epoxide, ethylene oxide-propane block polyether, oil-solubility polyether; 0.01-1.8% any one or mixture of thiadiazoles polysulfide, benzenetriazole-aldehyde-amine condenses, and benzenetriazole fatty acidic ammonium salt; 0.01-1.5% any one or mixture of alkyl-naphthalene sulfonate, benzotriazoles, and alkylphosphoricimidazole salt; 0.01-1.0% any one or mixture of vulcanized cotton seed oil, vulcanized alkene cotton seed oil, fatty acid ester, phosphonic ester, and molybdenum phosphate sulfate; 0.05-2.5% any one or mixture of vulcanized fatty acid ester, vulcanized vegetable oil, vulcanized isobutene, polysulfide, and phosphite ester; and basic oil.

Description

technical field [0001] The invention relates to a lubricating oil composition, in particular, it is a compound oil film bearing oil composition with anti-oxidation, anti-emulsification, anti-rust and anti-wear properties, especially suitable for steel plate high-speed line rolling mill and Morgan Twisted high speed wire rod mill. technical background [0002] Oil film bearings use the principle of dynamic pressure lubrication, that is, rely on the relative movement of the shaft and the bearing components, with the help of the viscosity of the lubricating oil and the hydrodynamic pressure formed by the wedge-shaped gap of the oil in the bearing, to form a bearing that carries the oil film. When the rolling mill is running normally, it is fluid lubricated. In rolling mill operation, mixed lubrication may occur due to vibration and excessive water intake or insufficient oil supply or oil quality problems. When starting or stopping, although there is lubricating oil between th...

Problems solved by technology

However, due to the operating conditions of high-speed wire rod mills (high temperature, water ingress) and the material of oil film bearings (small gaps, bearing bushes made of Babbitt alloy, silver-plated bearing covers, etc.) and alternate mixed lubrication, it is easy to cause bearing roughening, wear and sintering , affect its anti-wear performance, and in severe cases, it will cause oil film rupture, burn the bearing, and affect normal production
