INFLUENCE OF THE GEOMETRICAL PARAMETERS OF SPLIT GEAR ELEMENTS ON THEIR DISPLACEMENT

Gearboxes are still a key element of drive transmission systems used in various technical objects and many transport means. The gearbox’s operation is associated with the emission of vibrations and noise. The quietness of gearboxes is a significant research problem, and in the case of means of transport, it is directly related to the comfort of passengers and the impact on the nearest environment, as it causes pollution with vibrations and noise. The subject of many studies is the search for new and improved design solutions to reduce the vibration emission of operating gearboxes. One such solution is the design of a split gear containing a ring made of a flexible material covered by patent protection, Pat. 244312. This paper assessed the influence of selected geometric parameters of the split gear’s flexible ring on the gear elements’ displacement due to the transferred load. As part of the research, simulation studies using the finite element method were performed for selected design cases of a split gear and the relative position of the flexible ring and the loaded gear’s tooth. The results show a significant effect of the flexible ring’s thickness and position relative to the loaded gear’s tooth on the displacements of the selected elements.
