DETERMINING THE REACTIONS OF BALLS SLEWING BEARING MOUNTED IN WORKING STRUCTURES OF THE SINGLE-BUCKET EXCAVATOR
Journal Title: Scientific Journals of Silesian University of Technology. Series Transport - Year 2014, Vol 2014, Issue 83
Abstract
In the article the problem of modeling methodology slewing bearings by take into account partial or complete structures of housing in the working machine is presented. The structures of two exemplary models are described. The object of the study was single-bucket excavator caterpillar type F250H. Basic parameters of analyzed bearing are presented. The finite element method has been used to the modeling procedure. The calculation which is needed to calculate the force loading of balls slewing bearing has been done using the ADINA program. The way of calculating single-row ball slewing bearing rings which is presented in this paper, used the analytic correlation which determine the permissible load of contact zone (ball-bearing race in slewing bearings) too. The chosen distributions of reactions loading on the balls are presented. The results are shown as a graph.
