Configuration - of rolling bearings bearing

Bearing configuration examples in table 5. 1 bearing configuration, has considered the preloaded, stiffness, shaft axis of scaling, installation error, etc. , is a typical configuration of the bearing. Table 5. A typical case of configuration and use of the bearing of the bearing configuration pick to use instance ( Reference) Fixed end free end O belong to the standard configuration, even if the axial expansion, bearing will not bear medium-sized motor, blower. The abnormal axial load. Suitable for installation error is little, high-speed applications. O can carry heavy load, impact load and amount of axial load of railway vehicle use 0 for cylindrical roller bearing a variety of traction motor structure are separated, so suitable for inside, need to use of the over surplus quantity of the outer ring. O can be used for a wide load. Ironmaking workbench rolling bearing, 0 to guarantee fixed end bearing stiffness, so mounted with back to back. Lathe spindle. O request shaft, bearing precision is good, less installation error. 。 Applicable to the axial load is not big, need both inner and outer interference fit of papermaking machinery optical path, the purpose of the stone teeth. Diesel locomotive axle, etc. Back. Suitable for high speed rotating, radial load is big, and have the axial load of internal combustion engine car gearbox, etc. Occasion. 。 In deep groove ball bearing outside diameter and bearing inner diameter between travel home design, avoid bear radial load
