DETERMINATION OF TRANSMISSION ERROR AT HELICAL GEAR

: This paper deals with the static transmission error issue, which is one of the measured parameters of vibration in gear pairs and transmission systems, which is connected to noise and vibration. The transmission error can be determined in several ways, including a technical experiment. However, due to time and financial reasons, this is not always possible, and therefore, the possibility of using numerical simulations is offered. In this paper, the approach using stress-strain quasi-static contact analysis using the finite element method in Ansys Workbench software is used. The advantage is, among other things, a good comparability of results. The input 3D CAD geometry is a helical gear pair, which was created fully parametrically, so that various configurations could be generated and analyzed, including the gear teeth modifications. The peak-to-peak value of the transmission error is the subject of evaluation, since it turns out as a significant cause of vibration. Based on the result, the presented approach with numerical simulation can be used as a very useful tool for comparison.
