Bearing lubricants can be broadly divided into two categories: lithium-based and calcium-based. Calcium-based grease - a calcium soap thickened mineral oil made from animal and vegetable fats and lime. Lithium-based grease - a low-condensation point lubricant thickened with natural fatty acid lithium soap. Lithium-based and calcium-based lubricating oils have excellent water resistance, mechanical stability, chemical stability, and thickening ability of lithium soap. After adding extreme pressure agent, anti-rust and other additives to the grease, various kinds are made. Long life fat. Brick machine bearings use harsh environments, long time, heavy load, and difficult maintenance. Therefore, most of them use lithium-based lubricants.
In the use of lithium molybdenum oxide based lubricants should pay attention to:
1. Molybdenum disulfide has good water resistance, good mechanical stability and pressure resistance, and is mainly used for mechanical lubrication of heavy loads.
2. Molybdenum disulfide has a certain corrosive effect on copper and its alloys. It is not suitable for transportation with copper pipes, which will lead to blockage of pipelines and cause oil shortage accidents.
3. Worm gears that are not suitable for copper alloy manufacturing will cause broken teeth due to corrosion.
4. It is not suitable for the rolling bearing of copper alloy as the cage, which will cause the cage to break due to corrosion.
5. When parts of copper and its alloys need to be lubricated, it is best not to use lubricating products containing molybdenum disulfide. This is a lot of equipment accidents to teach
