Analysis of causes and effects errors in calculation of rolling slewing bearings capacity

Abstract

In the paper the basic design features and essential assumption of calculation models as well as the factors influencing quality improvement and improvement of calculation process of bearing capacity of rolling slewing bearings are discussed. The aim of conducted research is the identification and elimination of sources of errors in determining the characteristics of slewing bearing capacity. The result of the research aims atdeterminingthe risk of making mistakes and specifying tips for designers of slewing bearings. It is shown that there is a necessity fora numerical method to be applied and that real conditions of bearing work must necessarily be taken into account e.g. carrying structure deformations as the first ones.
