Introduction
Bearing hinges are widely used in various mechanical equipment and play an important role in reducing friction and wear. Lubrication and lubricant selection technology are crucial for the performance and service life of bearing hinges. In recent years, researchers have made significant progress in this field, and this article will summarize the research progress on lubrication and lubricant selection technology of bearing hinges.
Lubrication technology of bearing hinges
1. Boundary lubrication: In this lubrication mode, the bearing hinge is in a state of insufficient lubrication, and the contact surface is in direct contact with each other, causing severe wear and tear.
2. Mixed lubrication: This lubrication mode is a combination of boundary lubrication and hydrodynamic lubrication. The contact surface of the bearing hinge is partially separated by the lubricant, which reduces friction and wear.
3. Hydrodynamic lubrication: In this lubrication mode, the bearing hinge is completely separated by the lubricant, forming a fluid film, which greatly reduces friction and wear.
Lubricant selection technology of bearing hinges
4. Base oil: The base oil is the main component of the lubricant, and its quality directly affects the lubrication performance of the bearing hinge. Common base oils include mineral oil, synthetic oil, and vegetable oil.
5. Additives: Additives are added to the base oil to improve the lubrication performance of the lubricant. Common additives include anti-wear agents, extreme pressure agents, and anti-oxidation agents.
6. Compatibility: The compatibility between the lubricant and the bearing hinge material is also an important factor to consider when selecting a lubricant. The lubricant should not react with the bearing hinge material, causing corrosion or damage.
7. Environmental factors: Environmental factors such as temperature, humidity, and dust will affect the lubrication performance of the lubricant, and the lubricant should be selected according to the specific working environment of the bearing hinge.
Conclusion
Lubrication and lubricant selection technology are important for the performance and service life of bearing hinges. The lubrication mode and lubricant selection should be based on the specific working conditions of the bearing hinge. Future research should focus on developing more efficient and environmentally friendly lubricants to meet the increasing demands of various industries.
