Other what are the types and application of the rolling bearing

Other types of rolling bearing with the purpose of the following: 1. Centripetal short cylindrical roller bearings to the heart of short cylindrical roller bearing roller and raceway contact as line contact, radial load capacity and radial stiffness is higher than ball bearings. This kind of bearing small friction factor, suitable for high-speed operation, but for to match the bearing of the shaft and mounting hole machining precision demand is higher, after installation and outer axis relative deviation should be kept under strict control, so as not to cause contact stress concentration. The centripetal short cylindrical roller bearing is widely used in large and medium-sized motor, locomotives, spindle, internal combustion engines, gas turbines, reducer, rolling mill, vibrating screen and lifting transportation machinery, etc. 2. Double row centripetal spherical roller bearing, double row centripetal spherical roller bearing outer ring raceway is spherical, as part of the bearing with inner mind, to adapt to the shaft and the relative deflection of the base hole can bear radial load and impact load, also can bear - Two-way axial load. This type of bearings is mainly used for rolling mill, papermaking machinery, engineering machinery, crusher, printing machinery and all kinds of speed reducer, etc. 3. Needle roller bearing needle roller bearing radial size small radial bearing capacity is very high, but not bear axial load, only used as the free cod of a shaft support. Needle roller bearing friction factor is big, especially without full needle bearing cage, greater friction factor, and therefore not suitable for high speed. This type of bearings is mainly used in automobile gearbox, universal joint, small engine crankshaft and connecting rod, hydraulic machinery, etc. 4. Thrust roller bearing thrust roller bearing can bear axial load, axial stiffness, carrying capacity is much higher than the same size of the thrust ball bearing, mainly used in vertical motor, Marine propeller shaft, slewing crane machine tool rotary worktable and compression screw, etc. 5. Wheel bearing wheel bearing is under heavy load, move or swinging - work rate is very low Class oversize bearings, can bear a large axial force, also can withstand the big radial force and overturning moment. In the design and application of this kind of bearing, - Generally does not consider the fatigue life, with a static load rating as a selection criterion. Wheel bearing is mainly used in mining machinery, engineering machinery, metallurgical equipment, heavy duty machine tools, large equipment and heavy equipment such as wind power.
