Problems solved by technology

These lubricating greases of various colors are produced according to the needs of equipment development; with the development of automation equipment in China, especially the emergence of intelligent robots, it is unrealistic to use lubricating oil for its various movable joints. Lubrication, the joint will become very large and complex, and the use of grease lubrication is a very good way of lubrication, the work positioning of intelligent robots must be very flexible and accurate, and the working environment is changeable, sometimes It is very bad. Practice has proved that the existing lubricating grease is difficult to meet the lubrication needs of the various joints of the intelligent robot. The main problems are: sticking at startup and sticking during operation, noise, and oil separation of the grease lead to deterioration of the lubrication performance. Poor, poor compatibility of plastic parts
However, problems such as sticking, oil separation and air bubbles in the grease that occur during the use of intelligent robots cannot be well resolved.
The service life is short, and it needs to be stopped for refilling in a short period of time, which affects production

Abstract

The invention discloses a preparation method of a special long-life lubricating grease for joints and bearings of an intelligent robot. The lubricating grease is a combination of non-dropping point lithium-based lubricating grease and non-dropping point organic silicon lubricating grease produced with special blended oil as the base oil. It is mainly made of mixed fat, and various additives are added, mixed, ground, filtered and vacuum-packed at 50‑80 °C. Among them, mixed grease accounts for 70-80 parts, rust inhibitor 0.1-1 part, potassium borate colloid solution 0.5-3 parts, vulcanized cottonseed oil 0.5-1.5 parts, and solid micropowder lubricant 0.5-20 parts. The lubricating grease of the present invention is suitable for the lubrication of intelligent robot joints and bearings in various environments. After 8,000 hours of experiments at room temperature, minus 40°C, humidity, rotation, rotation, and medium-to-heavy load environments, the performance of the lubricating grease is basically stable, and each joint Flexible movement, no stagnation, no vibration, no oil flow, low noise, the friction pair is as bright as new, and no wear can be seen under the microscope.

Description

technical field [0001] The present invention relates to lubricating grease, especially the preparation method of long-life lubricating grease special for intelligent robot joints and bearings Background technique [0002] Grease is a thick, greasy semi-solid.
