Abstract
The paper deals with creation of functional parametric 3D model of slewing bearing. The slewing bearing is loaded by the radial force that acts from the centre of the bearing and it is also perpendicular to the axis of bearing. 3D fully parametric model of slewing ring was designed in Creo Parametric 3 and it is controlled by the ball diameter. To calculate several geometric bearing modifications, the 3D model from Creo was imported to the Ansys Workbench computational program. Based on many analysis in Ansys, it is possible to evaluate the size of contact pressures, determine the most loaded place and compare values between individual bearing modifications. By transferring the measured values of the contact pressures to the Microsoft office, it was possible to construct a graphical dependence between the values of measured stresses and the magnitude of the radial force acting on the slewing bearing.
