ANALYSIS OF NONCIRCULAR GEARS MESHING
Mots-clés :

Based on a general procedure, that uses the supershape equation to generate the pitch curve of the driving gear, and on an analytical approach for the generation of tooth profiles, the paper presents an analysis of the noncircular gear meshing. A first step considers the simulation of rolling, in 2D space, and validates the geometrical and kinematical calculations made in the design phase. Further, the 3D path of contact is analyzed and its distribution and evolution during gears meshing are monitored. Knowing how the path of contact evolves during gear meshing is important for further investigations such as stress and displacement distributions. The lack of researches regarding the meshing conditions of noncircular gears highlights
the importance of this paper.
