Gears in gear shafting are exposed to high intensity of stress of complex sharing. Modeling of gear geometry was preceded by analysis of work condition and analysis of geometric forms and accomplished solutions. Purpose of work was finding a form gear of minimum size necessary to transfer the given load for adequate gear ratio. Conditions between size of gear and moment of inertia were made in function of gear ratio and rotary moment. For finding an optimal form, we started from Hertz’s pressure on flank of cogs and intensity of stress in bottom. Conditions between size of gear ratio, module, axis distance, with of gears i intensity of stress on cog flank and in bottom. Parametric modeling of gear geometry using CAD software in outlines of this work should be signification for next two aspects: presents a developed method for gear geometry shapes modeling.

Key words: Gear; gear shafting; parametric modeling
