As the core component of mechanical transmission,
bearings carry the force and torque of rotational motion, so their operating state directly affects the performance and life of the equipment. Lubrication is one of the key factors for bearings to maintain good operation.
The importance of bearing lubrication Reduce friction and wear: Friction is inevitable when bearings are working, and proper lubrication can reduce the friction coefficient, reduce wear, and extend the service life of bearings.
Cooling and sealing: Lubricants can form a protective film between bearings and the external environment, play a role in sealing and cooling, effectively reduce the operating temperature of bearings, and improve work efficiency.
Reduce noise: Good lubrication can reduce the noise generated when bearings are running, and improve the running stability and comfort of equipment.
Bearing lubrication method Grease: Grease is one of the most common lubrication methods. It is composed of base oil and additives, has good viscosity and adhesion, and is suitable for high-speed, high-temperature and sealed bearings.
Lubricating oil: Lubricating oil is suitable for high-speed bearings and continuously running machines. It has good fluidity and cooling properties, can form a uniform oil film in the bearing, and reduce friction.
Solid lubricants: Solid lubricants are usually used in bearings with high temperature, high load and low speed operation. Solid particles such as molybdenum, copper, lead, etc. can form a uniform lubricating film on the bearing surface to reduce friction and wear.
Lubricant selection working conditions: Select the appropriate lubricant according to the working conditions of the bearing, taking into account factors such as the load, speed, and temperature of the bearing.
Wear resistance: The wear resistance of the lubricant is one of the important indicators to measure its performance. Selecting a lubricant with good wear resistance can effectively extend the service life of the bearing.
Temperature stability: The lubricant should not decompose or fail at high temperatures and should have good temperature stability to ensure the normal lubrication of the bearing under various working conditions.
Sealing performance: For sealed bearings, the sealing performance of the lubricant is crucial. Lubricants with good sealing performance should be selected to prevent external contaminants from entering the bearing.
Bearing lubrication maintenance Regularly replace the lubricant: According to the use of the equipment and the manufacturer's recommendations, replace the lubricant regularly to keep the bearing in good lubrication.
Clean the bearing surface: When replacing the lubricant, the bearing surface and lubrication cavity should be cleaned to prevent contaminants from mixing into the lubricant and affecting the lubrication effect.
Pay attention to the amount of lubricant added: too much or too little lubricant will affect the normal operation of the bearing, and the amount of lubricant added should be adjusted appropriately according to the actual situation.
Pay attention to the bearing temperature: Check the operating temperature of the bearing regularly. If the temperature is abnormally high, check the lubrication of the bearing in time to ensure the normal operation of the bearing.
Bearing lubrication is one of the important factors to ensure the normal operation of mechanical equipment. Choosing the right lubrication method and lubricant is of great significance to improving the performance of the equipment and extending its service life. Therefore, in practical applications, we should pay full attention to bearing lubrication technology, perform lubrication maintenance regularly, and ensure that the bearing is in a good lubrication state to ensure the safe and stable operation of the equipment.
