SKF bearing has rolling friction and sliding friction. Sliding friction is caused by the deviation of SKF bearing in the surface curve and load bearing deformation. For example, a rolling body and a ring, as the ball and ring is not absolutely rigid, contact area, they always produce elastic deformation, the theories for point contact or line contact, and in fact the load working conditions are changed into surface contact, thus having contact points with different diameters have different line speed and sliding friction. Also due to various reasons will make a rolling body and a holding device and between the holder and the inner and outer ring sliding friction. And sliding friction increases with increasing speed and load, in order to reduce friction, wear, reducing temperature, noise, preventing the bearing components rust, correct selection of lubricant and adopt reasonable lubrication, suitable control of lubricant quantity is to improve the project to the bearing life.
bearing oil or grease on the basis of:
Advantages of the SKF bearing is lubricated by the:
1) in certain operating specifications, the use of specific oil grease lubrication starting torque and friction loss significantly small.
2) as the lubricating oil in the loop heat plays the role of cooling, it can make the bearing to rotate speed relatively high.
3) can meet the use of high temperature.
4) for fat, must the demolition of the connecting parts, lubricating oil, there is not this trouble.
5) SKF bearings in the gear box of the lubricating oil lubrication is very appropriate, because the oil at the same time also lubrication of gears and bearings to splash way.
6) in the SKF bearing grease is gradually wear, abrasive products, from the outside through the penetration and aged sealing device product contamination, if not timely replacement, causing accelerated bearing wear, and application of liquid lubricants can be filtered, and ensure the normal operation of.
