How To Achieve Optimal Bearing Lubrication
The Importance Of Bearing Lubrication
- Reduction in friction and wear
Lubricant reduces friction: The correct lubricant can effectively reduce the internal friction of the bearing and reduce the surface contact resistance between mechanical parts.
Prevent wear and tear: Effective lubrication forms a protective film to prevent the internal parts of the bearing from unnecessary wear due to friction.
- Heat dispersion and control
Heat dissipation: Bearings generate heat during movement, and good lubrication can help disperse the heat effectively and prevent excessive heating.
Thermal Control: Proper lubrication helps maintain the proper operating temperature of bearings and prevents performance degradation and damage caused by overheating.
- Sealing effect and anti-corrosion
Sealing effect: Lubricant can form an effective seal to prevent external impurities and contaminants from entering the bearing and keep the interior clean.
Anti-corrosion: Good lubrication can prevent the inside of the bearing from being affected by humidity and corrosion, extending its service life.
- Noise reduction
Reduce friction noise: Proper lubrication can reduce noise caused by friction and improve the smooth operation of mechanical systems.
Effective sound insulation: The use of lubricants helps isolate vibration and noise generated during mechanical movement.
- Improve overall performance
Reduce energy consumption: Effective bearing lubrication reduces the energy consumption of the mechanical system and improves energy utilization efficiency.
Enhanced performance: Optimal lubrication can improve the operating efficiency of bearings and increase the performance of mechanical systems.
- Extend bearing life
Reduce wear and damage: Effective lubrication delays wear and damage of internal parts of the bearing, extending the service life of the bearing.
Improved reliability: Good lubrication is a key factor in ensuring the reliability of bearings and the entire mechanical system.
Lubrication Requirements For Different Types Of Bearings
1.Rolling bearings
- Demand characteristics: Rolling bearings usually include ball bearings and roller bearings, which are designed to reduce friction and improve load-bearing capacity.
Lubrication - requirements: For rolling bearings, the lubricant should have the characteristics of reducing the friction coefficient, improving wear resistance and withstanding high loads.
2. Sliding bearings
- Demand characteristics: Sliding bearings are mainly composed of shaft sleeves and sliding bushings. Their working principle is to support and reduce friction through the lubricating film between the sliding surfaces.
- Lubrication requirements: Sliding bearings need to have good lubricating film formation capabilities to reduce friction and wear while providing effective sealing.
- Demand features: Angular contact bearings are designed to carry radial and axial loads, and their internal angles make them suitable for higher speed applications.
- Lubrication requirements: For angular contact bearings, lubrication should have the ability to maintain stability and reduce friction under high-speed operation.
4. Thrust bearing
- Demand characteristics: Thrust bearings are specially designed to bear axial loads and are divided into one-way and two-way thrust bearings.
- Lubrication requirements: Thrust bearings require lubricants that can effectively support axial loads, reduce friction and resist thrust.
- Demand characteristics: Self-lubricating bearings usually have integrated lubricants and do not require external lubrication.
- Lubrication Requirements: With self-lubricating bearings, the key is the durability and adaptability of the lubricant to ensure stability over time.
6. High speed bearings
- Demand characteristics: High-speed bearings are designed to work under high-speed operating conditions and require lower friction and higher stability.
- Lubrication requirements: The application of lubricants in high-speed bearings requires excellent cooling and resistance to bubble formation to ensure performance under high-speed conditions.
7. Special environment bearings
- Demand characteristics: Bearings working in harsh environments, such as high temperature, corrosion or high humidity environments.
- Lubrication requirements: Bearings in special environments require lubricants that are resistant to high temperatures, corrosion, and humidity to ensure their reliability under extreme conditions.
Lubricant selection
Considerations of working environment conditions
- In high-temperature environments, choose high-temperature lubricants that can work stably, such as high-temperature resistant grease or oil.
- At low temperatures, lubricants are required to have low-temperature fluidity and frost resistance to ensure performance in cold conditions.
Load and speed requirements
- For bearings subject to high loads, choose a lubricant with a high load-carrying capacity, such as grease with EP (extreme pressure) additives.
- Under high-speed operation, use lubricants with low friction and high viscosity index, such as synthetic oil.
Anti-corrosion and sealing requirements
- In harsh environments, choose lubricants with anti-corrosion properties to protect the bearings from the effects of corrosion.
- For applications requiring sealing, use a lubricant with a high viscosity that creates an effective seal to prevent impurities and contaminants from entering the bearing.
Lubrication intervals and maintenance convenience
- Choose lubricants with long lubrication cycles to reduce maintenance frequency and improve production efficiency.
- For applications requiring frequent maintenance, choose a lubricant that is easy to refill and replace to reduce maintenance costs.
Temperature control
- Under high temperature working conditions, use lubricants with good thermal stability to prevent lubricant failure.
- During high-speed operation, choose a lubricant that can provide good cooling performance to prevent the bearing from overheating.
Resistance to impurities and particulate matter
- In environments with a lot of dust and large particles, choose a lubricant with good resistance to impurities to extend bearing life.
- Consider the filtration performance of the lubricant to reduce the impact of impurities on the bearings.
Cost-effectiveness and sustainability
- Consider lubricant performance and cost to select the lubricant that best meets application needs.
- Consider using environmentally friendly lubricants to meet the requirements of sustainable development.
Working Principle
1. Friction reduction: The lubricant forms a thin lubricating film on the bearing friction surface, reducing the direct contact between metal surfaces, thereby effectively reducing friction.
2. Wear protection: Lubricant can form a protective film between bearing parts, slow down wear caused by friction, and extend bearing life.
3. Heat dispersion and cooling: Lubricant helps to evenly disperse the heat generated in the bearing to prevent local overheating.
Cooling effect: Some high-efficiency lubricants have good cooling properties and help control the operating temperature of the bearing.
4. Sealing and anti-corrosion: Lubricant can form an effective seal to prevent external contaminants from entering the bearing and keep the interior clean.
Anti-corrosion: Lubricants containing anti-corrosion additives protect bearings from corrosion and oxidation.
5. Load distribution: By forming a lubricating film, lubricants help distribute pressure when bearing loads, enhancing the bearing’s load-bearing capacity.
6. Vibration absorption and shock absorption: Lubricants help absorb and reduce vibrations generated during bearing movement and improve the stability of mechanical systems.
7. Adsorb impurities and particles: Lubricants have the ability to absorb impurities and particles, helping to remove contaminants that may cause damage to bearings.
8. Improve sealing effect: Appropriate selection of lubricant can help increase the flexibility of seals and improve the sealing effect of bearings.
