Modelling of ball bearing mechanical behaviour

In this thesies was conducted an analysis of the static and dynamic behavior of ball bearings, with special care on four-point contact ball bearing. The main goal of the research in this paper was to develop a software solution for the analysis of static and dynamic behavior of the deep grooved ball bearings and four-point contact ball bearing, apropose identification of behavior in exploations and determination fatique life of bearings using mathematical models. Experimental bearing test was performed, in order to verify the results obtained by applying the developed mathematical models, as well as by applying general - purpose software systems, which are based on the finite element method. The experimental test was performed for two types of bearings: for the deep grooved ball bearing FKL 6006 and the four-point contact ball bearing FKL LSQFR 308

Analysis the amount of lubrication and roughness of raceways on dynamic behavior on the ball bearing

The operating principle of rolling bearings generates vibrations that come from the periodic change in the stiffness of the bearing. The vibration level of the bearing depends on a large number of factors such as waviness, surface roughness of the raceways, deviation of the raceway radius, exploitation conditions, amount of lubrication in the bearing and other. This paper presents the influence of the roughness of the raceways and the amount of lubrication on the level of vibrations of the ball bearing, designation 6006. The determination of the influence of these parameters was done experimentally. The experiment was performed according conditions prescribed by ISO 15242-2, and the analysis of the measured signals was performed according to the guidelines given by the standard ISO 15242-1

The Results of Changing the Current Solution Concept of Universal Motor Gear Reducers with Helical Gears

By analysing and comparing the existing solutions of universal gear reducers with helical gears of the leading manufacturers, it can be noticed the effort to increase the load capacity of the gear reducer within the same axis height. In this way, the manufacturers can offer smaller (cheaper) gear reducers, as well as to simultaneously increase the values of the largest gear ratios. This concept enables the offer of lower-stage (cheaper) gear reducers with higher gear ratios in certain segments of gear ratios. By these efforts, it is reached the maximum, but the further increase is possible only by changing the current concept of universal gear drives. Within this paper, it is given an overview and analysis of one of the possible new conceptual solutions of modern universal motor gear reducer
