Abstract Details

2020, Master of Science, Ohio State University, Mechanical Engineering.
In this study, computationally robust routines for hypoid surface generation and instantaneous contact line determination are proposed. The developed surface generation routine accurately defines undercut gear profiles for Face-Hobbed and Faced-Milled hypoid gears produced by Formate and generate processes. An approximation routine is incorporated into the developed surface generation model to obtain a stable initial guess for the non-linear solver. The proposed model successfully overcomes the computational challenges posed by higher order motion and complex blade profiles in the surface generation process. The efficacy of the developed routine was examined using industrial gear design having significant undercut, composite cutter profiles and generating motions. Unloaded Tooth Contact Analysis (UTCA) using the Ease-off method is outlined for obtaining the orientation and the location of the instantaneous contact lines. To enhance the accuracy for the prediction of the possible area of contact between gear and pinion, effects of roll angle on ease-off blank definition are investigated. A new blank definition routine for the Ease-off method is subsequently developed for accurate loaded contact analysis for the hypoid gears. The stabilization modules developed for the surface generation are extended to the Ease-off routines enhancing the robustness of the routines and enabling the visualization the complex cutter profiles (Toprem, Flankrem) and higher order motions.
