What are the advantages of ball bearings compared with ball bearings?
Upstairs, 2 can copy these more information, I am surprised, ball bearings and ball bearings is not a meaning? All ball, bearings, the landlord's wrong
Ball bearing: a kind of rolling bearing, which is placed between the inner rim and the outer rim, and can bear greater load. Also called ball bearing
1. the coefficient of friction of rolling bearing is smaller than that of sliding bearing and the transmission efficiency is high. The coefficient of friction of plain sliding bearings is 0.08-0.12, while the coefficient of friction of rolling bearings is only 0.001-0.005;2., rolling bearings have been standardized, serialized and versatile. They are suitable for mass production and supply, and they are very convenient for use and maintenance;3. rolling bearing steel, and after the heat treatment, therefore, bearing not only has high mechanical performance and long service life, and can be used in the manufacture of sliding bearing the expensive non-ferrous metal saving;4., the internal clearance of rolling bearings is very small, and the machining accuracy of each part is higher. Therefore, the running accuracy is higher. At the same time, the rigidity of the bearing can be increased by preloading. This is very important for precision machinery;5. some rolling bearings can bear radial load and axial load at the same time, therefore, the structure of bearing support can be simplified;6., because of the high efficiency of rolling bearings, less heating, so it can reduce the consumption of lubricating oil, lubrication and maintenance easier;7. rolling bearings can be conveniently applied to any axis of space.
