Abstract
The invention relates to a lubricating grease composition for bearings. The lubricating grease composition is characterized by being prepared from the following raw materials in parts by weight: 25-30 parts of a thickening agent, 85-90 parts of base oil and 2-4 parts of an additive, wherein the thickening agent is a mixture of carbon black, aryl urea and polytetrafluoroethylene; the base oil is a mixture of mineral oil, polyether and alkylbenzene oil; the additive is a mixture of sodium pentahydroxyl caproate, isobutanol, butadiene styrene rubber and fatty acid potassium. As the mixture of mineral oil, polyether and alkylbenzene oil is taken as the base oil, the lubricating grease composition is rich in resource and good in lubrication effect; as the mixture of carbon black, aryl urea and polytetrafluoroethylene is taken as the thickening agent, the viscosity of the lubricating grease is ensured; due to addition of sodium pentahydroxyl caproate, isobutanol, butadiene styrene rubber and fatty acid potassium, the wearing resistance of the lubricating grease composition is improved, the stability of the lubricating grease composition is kept under the high-speed rotation condition, and the service life of the lubricating grease composition is prolonged.
Description
Technical field
The present invention relates to a kind of bearing grease composition, belong to industrial chemical technical field.
Background technology
Lubricating grease is dispersed in by one or more viscosifying agents the series lubricant agent with non-newtonian flow body characteristics between semi-fluid to solid obtained in one or more liquid lubricants.Grease base eigen has certain kenel, and be easy to attachment, mobility is lower than corresponding base oil.Lubricating grease is used for the friction portion of machinery, plays lubrication and sealing function.
Bearing rises fixing in mechanical transmission course and reduces the parts of load frictional coefficient, alternatively, when other parts produce relative movement each other on axle, is used for reducing the fixing parts of frictional coefficient in power transmission process and retainer shaft central position.Bearing is a kind of very important component in contemporary mechanical means.Its major function is supported mechanical rotator, in order to reduce the mechanical load frictional coefficient of equipment in transmission process.By the difference of motor element nature of friction, bearing can be divided into rolling bearing and sliding surface bearing two class.The main shaft of work mechanism, in order to improve working (machining) efficiency, the main shaft of preferred high speed rotating, adopts various lubrication technology in this bearing.Along with developing rapidly of bearing industry, require that lubricating grease has good antiwear and friction reduction property to reduce device drives power, save energy consumption and improve work-ing life.
