Defining the change of meshing rigidity caused by a crack in the gear tooth’s foot

Abstract

In this paper, research results concerning the influence of the cracks at the base of the tooth of wheel on the change of the wheel rigidity is presented. In order to achieve this, a series of experiments was conducted with the use of models FEM and BEM. The correctness of the models was verified with the use of analytic method, whereas the final results were confirmed in a research experiment conducted on the endurance machine MTS. The achieved results enabled the conduction of research devoted to the possibility of use of simulation models of toothed gears to get the teaching data for artificial neural networks. The best of neural networks correctly worked during tests with real data.

Modal analysis and simulation on effect of correction factor (cf) in spur gear tooth profile

“…This gear tooth failure can be analyzed and simulate using the correction factor made in the mating or engagements of the gears. The most important criteria for the quality of meshing of gears are the transmission error, the proper location of bearing contact, and the maximum tooth contact pressure in (P. Czech, 2010). The aim of the gear tooth correction factor is to determine the desired centre distance between the gears without any undercuts, backlash and interference and without the failure of the gear system.…”
