Abstract

The invention discloses a low-noise lubricating grease and a preparation method and application thereof. According to the technical scheme, the low-noise lubricating grease is characterized by being prepared from the following raw materials in parts by weight: 65-85 parts of base oil, 10-15 parts of C12-C22 hydroxy fatty acid, 3-9 parts of lithium hydroxide, 2-7 parts of boric acid and 4-8 parts of multi-effect additives. The invention also discloses the preparation method of the low-noise lubricating grease and an application of the low-noise lubricating grease in a high-accuracy micro mechanical bearing. The low-noise lubricating grease disclosed by the invention is reasonable in formula and high in production efficiency. According to the low-noise lubricating grease and the application thereof disclosed by the invention, the low-noise lubricating grease is ground by using a patent product grinding machine (a patent number: ZL201220281084.7) of the company, the particle diameters of mechanical impurities contained in the lubricating grease are controlled to be smaller than that of the prior art, the vibration decibel value of the micro mechanical bearing is less than that of the lubricating grease in the prior art, the operation accuracy of the micro mechanical bearing is ensured, the vibration and the abrasion are reduced, the vibration decibel value of the micro mechanical bearing is less than 40, and the mechanical impurities contained in the lubricating grease are smaller than 2 micrometers.

Description

technical field [0001] The invention belongs to the technical field of lubrication, and in particular relates to a low-noise lubricating grease and a preparation method and application thereof. Background technique [0002] With the development of the economy, mechanical equipment puts forward higher requirements for lubricating grease. In many technical fields, ultra-pure and low-noise lubricating grease is required in order to reduce the noise value of rolling bearings and the acoustic emission in the air. It meets the noise limits and tight running tolerances of precision rolling bearings and guarantees economical and energy-saving operation. There are following problems in the low-noise lubricating grease used in my country at present: one, low-noise lubricating grease is used as high-grade lubricating grease, and import price is often more expensive, is unfavorable for the development and popularization of low-noise lubricating grease; The production process of lubricat...
