PARAMETRIC MODELLING OF INVOLUTE GEARS WITH CURVILINEAR SHAPED TEETH

Caius STĂNĂȘEL, Iulian STĂNĂȘEL

Abstract


Gears are mechanical components used in various industrial applications. They ensure a constant transmission ratio and efficient operation at different speeds and power levels. The 3D modeling of gears with curved teeth allows design optimization, reducing noise and vibrations, as well as cost reduction through virtual testing and the minimization of manufacturing errors by integrating CNC processes and 3D printing. The article presents the parametric design of cylindrical gears with curved teeth with epicycloidal flanks. Using the parametric equations of the epicycloid and involute, calculation programs were developed to determine points on the flanks. These points were used in CAD software to obtain the 3D model, which allowed the observation of the theoretical position of the contact area.
