ANALYSIS OF CAUSES OF BEARING DAMAGE OF BRIDGE SUPPORT OF STACKER-RECLAIMER ZGOT 15400.120
Journal Title: Scientific Journals of Silesian University of Technology. Series Transport - Year 2014, Vol 2014, Issue 83
Abstract
An example of the analysis of a large-size slewing bearing supporting the bridge of the largest in Poland stacker-reclaimer. The turning node was constructed based on the catalogue slewing bearing with four-point contact. The analysis was performed in order to identify the causes of rapid degradation of the bearing. In addition to the macroscopic tests, not described in this article, to verify the correct configuration of the supporting components and to determine the distribution of the loading, the FEM model was build, including the original replacement elements for modelling balls with four-point contact. The measurements of strain of occurred loading were also conducted. Particular attention was paid to the catalogue selection procedures of slewing bearings. The results of no compatibility between algorithms published by various manufacturers of bearings was shown.
