The Effects of Hollow Ratio on the Radial Bearing Properties of Pre-Loaded Cylindrical Roller Bearings

Abstract:

The finite element method is adopted to analyze the pre-loaded cylindrical roller bearings according to the theory of contact mechanics. The effects of hollow ratio on the radial stiffness of bearings, the maximum contact stress of rollers, and the maximum radial load of bearing are analyzed. The analysis results show that the smaller the hollowness is, the larger the radial stiffness of pre-loaded cylindrical roller bearings, the maximum contact stress of the rollers, and the maximum radial load of the bearing would be. Under different magnitude loads, the reasonable combination of interference magnitude with the hollowness can not only increase the stiffness of roller bearings, but also decrease the maximum stress of rollers, which provides a reference for the design and manufacture of pre-loaded cylindrical roller bearings.
