Abstract

By merging bearing specific advantages, combined roller and plain bearings can be used to meet the increasing requirements for high performance machine tools. Due to their sensitive functionality, a robust bearing design is indispensable for its industrial applicability. Different bearing types lead to different and sometimes contradictory requirements. This article presents a design methodology including basic design rules for industrially applicable bearing combinations. The methodology respects the conflict of objectives in the distribution of the force flow to the different bearing components. The bearing stiffness is used as an indicator for the bearing's functional capability. A semi-analytical model based on the theory of hydrodynamic lubrication was extended by a roller bearing model to simulate the bearing behaviour. In addition, both full-rotation and pivoting tests were carried out to validate the model and investigate the influence of rotational speed and radial displacement on the bearing’s stiffness.
