Superfine oil for abrasive machining of high-lubrication and high-water-separability bearing

Abstract

The invention discloses superfine oil for abrasive machining of a high-lubrication and high-water-separability bearing. The superfine oil consists of mineral oil, polymeric carboxylic acid, organic amine, a surfactant, a synthetic lubricant, an anticorrosive agent, an extreme-pressure additive and an antioxidant. The superfine oil has an excellent lubricating property, a Bouton tester is used fortesting, and a friction coefficient value of raw oil is less than or equal to 0.1; the superfine oil has excellent water separability, and the separation time of oil and water is less than or equal to 10 min (50 ml of sample is added into 50 ml of water, and the mixture is turned for 10 times); and raw materials in a formula are not toxic and harmful substances which influence the environmental safety and human health, the biological median lethal dose LD50 of the product is more than or equal to 5,000 mg / kg, the median lethal concentration LC50 is more than or equal to 5,000 mg / m<3>, the respiratory mucosa irritation is less than or equal to class 1, and the superfine oil has reliable safety and sanitation quality.

Description

technical field [0001] The invention relates to a super essential oil for bearing grinding. Background technique [0002] China's economic development has promoted the demand for a large number of high-precision and high-reliability bearings, and has also laid a good foundation for the steady development of the bearing industry. At present, the internal structural parameters of deep groove sealed ball bearings in my country are almost the same as those of advanced foreign companies, but the vibration and noise levels of such products in my country are far from those of foreign products. A large number of tests at home and abroad have shown that: cages, rings, and processing quality have varying degrees of influence on bearing vibration, and the main influencing factors are roundness, waviness, surface roughness, and surface bumps on the rings. In order to obtain better machining accuracy, higher requirements are put forward for bearing super essential oil in the manufacturi...

AI Technical Summary

Problems solved by technology

At present, the friction coefficient of commercially available ultra-essential oils is above 0.2, and the oil-water separation time is above 30 minutes. The formula generally contains chlorinated paraffin and other toxic substances that endanger environmental safety and human health. There are also smoke, oil mist, Disadvantages such as not easy to clean can no longer meet the requirements of high-end customers' continuous improvement of bearing processing technology and the environmental friendliness requirements that people are increasingly concerned about
