GEOMETRICAL IDENTIFICATION OF CYLINDRICAL CARRIER OF AXIAL BEARINGS WITH BIG DIAMETERS

Abstract

The paper deals with the analysis of deformation of cross section of cylindrical carrier of axial bearings with big diameters at portal cranes. Fundamental theory on calculating plates and shells with restrictions about proper function of these bearings, helps to define relations for determining required height of cylindrical carrier with the following conditions being met: first, the change of cylindricality of upper part has to be as small as possible; second, movements of supporting points of support surface for connecting axial bearing must not exceed the allowed value. Finally, the expressions for determining height of cylindrical carriers are presented and they can be used by construction engineers when designing optimal connection between rotating platform and carrying structure of portal cranes through axial bearings having big diameters.
