Sažetak
The research into standard spur gear has been performed in order to clarify complex alternation modus of tooth fillet stress in relation to the influence of rim thickness and the considered actual tooth facewidth. The tooth stress field was determined by means of 3D FEM and by use of the developed numerical model consisting of both pinion and wheel. The imposed appropriate boundary conditions enabled the model to take into account the load sharing between two tooth pairs in contact. For the meshing phase of single and double pair tooth contact, maximum stress at the tooth fillets was followed and compared. Based upon the obtained stress results on tensile side of the loaded teeth, the positions on the path of contact where contact changes from double to single and vice versa were separated for the assessment of the appearance of alternating stress condition at the fillet. For the point on tensile side of the loaded tooth, where maximum fillet stress occurs at these chosen meshing points, the stress alternation was observed as the meshing phase was proceeding. The established stress behavior of thin-rimmed gears differs considerably from the solid ones, and the presence of alternating stress cannot be neglected when a gear fatigue strength is evaluated.
