Abstract
This paper gives an overview of the most important model collections in Europe at that time and the current status of preservation and use. This study investigates the contact patterns and contact stresses of intersected concave conical gear pairs generated by shaper cutters. The mathematical models of gear pair have been derived based on the theory of gearing and the generation mechanism. Then, contact pattern simulation have been performed by SolidWorks. Meanwhile, the commercial software, ABAQUS, capable of contact analysis of two 3-D deformable bodies is applied to evaluate the stress distribution on the tooth surfaces. Several numerical examples are presented to demonstrate the results of contact pattern Simulations and stress analyses of the gear pairs with various design parameters. The results show that concave conical gear pairs relieve the high contact stress problem which is inherent in conventional conical involute gear pairs.
