A practical application of the spherical involute surface to the forged straight bevel gears is provided and demonstrated in this work. Conjugate (pure involute) theoretical surfaces are developed from the input design parameters. The surfaces are modified to suit the actual application (automotive differential). The unloaded (or low load) tooth contact analysis of modified surfaces is performe...

The aims of this study were to introduce a novel electronic system for reliable evaluation of the non-functional tooth contact in patients with temporomandibular disorders (TMDs) and investigate the possible associations between the non-functional tooth contact and some characteristics of the patients with TMD. We designed and installed a software program to send emails regarding the non-functi...

In this study, an optimization methodology is presented to systematically define head-cutter geometry and machine tool settings to introduce optimal tooth modifications in spiral bevel and hypoid gears. The goal of the optimization is to simultaneously minimize the tooth contact pressure and the angular displacement error of the driven gear (the transmission error), to maximize the elastohydrod...

Article history: Received 18 February 2013 Received in revised form 19 September 2013 Accepted 22 September 2013 Available online 24 October 2013 A method for predicting and analyzing the tooth contact pattern, vibration, and strength of a generated hypoid gear is needed to achieve a low-noise design and adequate quality control. However, it is not easy to analyze the performance of a generated...

Abstract. To improve the bearing capacity and provide mathematical model basis for vibration noise reduction of variable hyperbolic circular-arc-tooth-trace (VH-CATT) cylindrical gear, tooth surface modification design method based on parabolic forming blade cutter inclination was proposed. The geometric inclined completed. modified equation deduced, influence parameters curvature characteristi...
