Durability calculations of bearings take in account the distribution of forces on rollers. Calculation of these forces in flexibly supported rings is the aim of the paper. We use simplified finite element (FE) models of bearings, which are integrated into the external geometry. This approach can consider the stiffness of the surrounding structure as well as the clearance of the bearing rings, the misalignment of bearings, shaft deflections, and the forces of crowning rollers. The presented results show an influence of the initial radial interference of the outer ring with housing on the distribution of forces in bearing rollers. As the radial stiffness of the housing is close to the stiffness of the outer ring interference, this causes considerable deformation of the housing. The presented approach is also able to calculate the distribution of contact pressures over any rolling element.

To achieve a correct function and maximal effectiveness of a pumping unit, it is necessary to correctly design the input dynamic parameters. This paper will present sensitivity analysis, which aims to find appropriate input parameters needed to realize the prescribed work tasks from the point of view of consideration of flexible member in the system.

Nowadays computational techniques utilization is essential part of the technical development. Visual form of data acquisition from simulations or solving of technical problems is the most effective approach. In the field of computer-aided design (CAD) 3D graphic visualization is certainty because makes it possible to design a very complicated parts and devices at a short time. Furthermore it enable to trace how these parts behave during operating regimes and make an optimization of required parameters. In this paper the engineering design of gravity orienting part tool for cylindrical bushing will be presented. Each of 3D components was designed in CAD software Pro/ENGINEER and in simulation software MSC.ADAMS virtual prototype was created. Using of the tools of parametric analysis for precising of model parameters in software MSC. ADAMS it was realized the optimization of chosen design and dynamic parameters of given designed system.
