Preparation of high-speed bearing grease

Abstract

The invention discloses preparation of high-speed bearing grease, and the grease is particularly applied for lubricating high-speed bearings in the industries of electronics, machine tool manufacturing, textile chemical fiber and the like. The grease consists of base oil and thickening agent, the penetration of the prepared grease is between 200 and 340 at the temperature of 25 DEG C, and the similar viscosity is smaller than 1400 at the temperature of minus 50 DEG C. The grease can meet the lubrication of the bearing the speed factor (DN value) of which is more than 2 million, can lubricate completely in a cold environment, and produces very small noise.

Description

Preparation of a high-speed bearing lubricating grease technical field The invention relates to a high-speed bearing grease. Especially used in the lubrication of high-speed bearings in electronics, machine tool manufacturing, textile and chemical fiber industries. Background technique The high-speed bearings we talk about in daily life mainly refer to bearings with a DN value greater than or equal to 1,000,000 (where D: bearing diameter, N: bearing speed). Due to the relatively high rotational speed of high-speed bearings and harsh industrial and mining conditions, there are high requirements for the adhesion of grease, working life and working temperature. The development of high-speed lubricating grease in our country is still close to zero. The main applications of high-speed bearing grease are electronics, machine tool manufacturing, textile and chemical fiber and other industries. In the past, because there were no related products in China, such as the lubricatio...
