Whether the installation of IKO bearings correctly affects the performance and life of the bearings
Bearings are one of the important components on construction machinery. Poor installation will affect their use and even cause failure of construction machinery.
If IKO bearings have foreign matter such as iron filings, burrs, dust, etc., the bearings will generate noise and vibration during operation, and even damage the raceways and rolling elements. Therefore, before installing the IKO bearing, it is necessary to ensure the cleaning of the mounting surface and the installation environment.
Lubrication has a very important influence on the operation and life of the bearing. Grease is made from base oils, thickeners and additives. The performance of the grease is primarily determined by the base oil. Generally low viscosity base oil is suitable for low temperature and high speed; high viscosity is suitable for high temperature and high load.
The thickener is also related to the lubricating properties, and the water resistance of the thickener determines the water resistance of the grease. In principle, the different greases of the brand cannot be mixed, and even the grease of the same thickener may have a bad influence on each other due to the different additives. IKO bearing surface is coated with anti-rust oil, which must be carefully cleaned with clean gasoline or kerosene, and then cleaned with high quality or high temperature high temperature grease for installation. Fully enclosed bearings do not need to be cleaned and refueled.
After the IKO bearing is installed, alignment may result in additional loads, friction and vibration of the bearing if not carefully aligned. These can accelerate fatigue and reduce the life of IKO bearings and can damage the life of other machine parts. In addition, increased vibration and friction can greatly increase energy consumption and risk of premature failure.https://www.supplyforever.com/
What are the common SKF bearing lubrication methods?
SKF bearings are lubricated in several ways, and each type of bearing and each type of bearing is also different when using lubrication, which is more conducive to maximizing the service life of SKF bearings, which is the highest performance of mechanical equipment. The state of performance.
1, solid lubrication
Under some special conditions, a small amount of solid lubricant is added to the grease. For example, adding 3~5% of molybdenum disulfide No. 1 can reduce wear and improve the resistance to pressure and heat. For high temperature, elegance, high vacuum and corrosion resistance. Special conditions such as anti-radiation and extremely low temperature, the solid lubricant can be added into engineering plastics or powder metallurgy materials to make bearing parts with self-lubricating properties, such as bonding the solid lubricant to the raceway with an adhesive. A lubricating film is formed on the cage and the rolling elements, which has a certain effect on reducing friction and wear.
2, oil lubrication:
Viscosity is an important characteristic of lubricating oil. The viscosity directly affects the fluidity of lubricating oil and the thickness of oil film formed between friction surfaces. The viscosity of lubricating oil at SKF bearing working temperature is generally 12-15cst. The higher the speed, the lower the viscosity, and the heavier the load, the higher the viscosity. Commonly used lubricating oils include mechanical oil, high-speed mechanical oil, turbine oil, compressor oil, transformer oil, cylinder oil, and the like.
Oil lubrication methods include:
a. oil bath lubrication
Oil bath lubrication is the most common lubrication method. It is suitable for the lubrication of low and medium speed bearings. Part of the bearing is immersed in the groove. The lubricating oil is brought up by the rotating bearing parts and then flows back to the oil groove. The oil level should be slightly lower than the minimum. The center of the rolling element.
b. drip lubrication
Drip oil lubrication is suitable for SKF bearing parts that need to supply lubricating oil quantitatively. The amount of dripping oil is generally one drop every 3-8 seconds. Excessive oil quantity will cause the bearing temperature to increase.
c. Circulating oil lubrication
The filtered oil is delivered to the bearing components by an oil pump, filtered through the lubricating oil after the bearings, and then cooled and used. Since the circulating oil can take a certain amount of heat to cool the bearing, this method is suitable for bearing parts with higher rotational speed.https://www.supplyforever.com/
