Analysis of the Influence of Large Diameter Bearing Support Structure Condition on Reliability in Operation

Abstract

The causes of support structure deformation of the large diameter bearing arise from external loads and they are variable by the magnitude and point where load acts. By forming a model of bonds, on the basis of which would be performed a theoretical analysis of the interaction of revolving and non-revolving parts in construction and transport mechanization machines, with the variation of geometric values of supporting structure elements, could be obtained some parameters that have a dominant influence on the increasing of necessary support surface stiffness for bearing bond. Therefore, the deformation of support surface must be smaller than allowed value. In this way, will be separated a typical carrying structures which favorably effect on functionality of bonds. Also, we noticed the shortcomings of these structures that should be eliminated. The result of such research and analysis should enable the fulfillment of the demands which placed before of construction and transport mechanization machines, i.e. the better adaptability of the excavator running machine with the leaning surface, as well as the radial-axial bearing support surface deformation must be kept under the limits that allows the proper functioning of bonds.
