Theoretical Research on the Radial Stiffness of Pre-Loaded Hollow Cylindrical Roller Bearings

Abstract:

For solving the problems of classical mechanics on the stiffness of hollow cylindrical roller bearings, the radial stiffness of pre-loaded hollow cylindrical roller bearings is analyzed with finite element method and the elastic deformation of inner and outer rings is also taken into account. The effects of load, interference magnitude, and hollow ratio on the bearing stiffness are researched fatherly. The results show that the bearing stiffness correlates not only with the interference magnitude and hollow ratio, but also with load, which offers the references for designing and using the pre-loaded hollow cylindrical roller bearings.
