Mathematical algorithm for calculating an optimal axial preload of rolling bearings with the respect to their life

The article deals with a description of a mathematical algorithm, programmed in the MATLAB environment of the company MathWorks. The algorithm serves a calculation of an optimal axial preload of rolling bearings. So that, the life of a bearing pair, arranged into "X" or "O" arrangement, is maximized according to a given load. Hence angular contact ball bearings and tapered rolling bearings are the subject matter of the article. Moreover, methods, that were used in the optimizing code, such as Hertz's contact of two bodies and Stribeck's load-distribution on rolling elements, are described in the article too. The finding is the dependency between total axial preload and life of a bearing pair. (paper)
