“…The determination of forces in bearings is statically impossible. To solve it a procedure used earlier by the author [19], [20], [21] was adopted. This procedure relies on iterative search for such displacements in bearings (displacements and deflections) that all equilibrium conditions are fulfilled:…”

Rolling bearings are considered to be rigid supports of a pinned nature. In fact, rolling bearings develop displacements that depend on the external load and the stiffness of the shaft on which they are supported. In addition, tapered roller bearings use preloading, which has an additional effect on the displacements in the bearings. these displacements affect the internal deformations in the bearings and thus the actual load on the bearing. This paper presents a methodology for determining displacements in bearings and actual loads in bearings, taking into account shaft stiffness and preload clamping. Then the bearing life was determined. Based on the obtained bearing life, the bearing life index was determined for the adopted load variants. On the basis of the results obtained it can be concluded that the consideration of the durability of individual bearings is insufficient, because it usually happens that when the durability of one bearing increases, the durability of the other bearing decreases. According to the author, the best solution is to combine the durability of both bearings and to consider the durability of the whole bearing system, not the individual bearings.

ResumeAngular ball bearings are commonly used whenever there is a demand to increase stiffness of a bearing. The aforementioned increase of stiffness can be achieved by obtaining proper preload in bearings. In common belief, preload has a negative consequence: it increases the load of rolling elements, which must lead to lower durability of bearing compared to the situation before the preload use. The objective of the research was to analyse how a change of load plane, while applying the preload, affects durability of angular ball bearings. In calculations of durability of bearings, besides elasticity of a shaft, radial, axial and bending elasticities of bearings were taken into consideration, as well.

The main purpose of using tapered roller bearings is to obtain high bearing stiffness. High bearing stiffnessis achieved by using an appropriate mounting clamp in the bearing system. The mounting clamp, or in otherwords, the pre-clamp, is currently selected based on experience. The literature lacks precise indicationsregarding the size of the initial clamp of the bearing arrangement depending on the external load, and it isselected intuitively. The wrong choice of preload can have a disastrous effect on the life of the entire bearingarrangement.This study aims to determine the maximum preload in the tapered roller bearing system, taking into accountits durability and the elasticity of the bearings and the shaft.In this article, different load variants are analysed, considering the effect of preload on the fatigue life of thebearing system, and recommendations are proposed for the acceptable preload value depending on the size ofthe bearings used.
