Abstract: A new approach for the computer-aided simulation of conditions of meshing and bearing contact of gear tooth surfaces is proposed. Using the developed computer programs, we may determine: (a) the kinematical errors, (b) the dimension and orientation of the instantaneous contacting ellipse, and its motion over the gear tooth surfaces and (c) the influence of errors of manufacturing and assembly, and the adjustment of gears to these errors. The proposed methods have been applied for spiral bevel gears and helical gears with circular arc teeth. We consider that the teeth of the gear and the pinion are generated by two different generating tool surfaces and this provides a localized bearing contact for the gear tooth surfaces.

Keywords: bearing contact; computer-aided simulation; gear tooth contact analysis; vehicle design; gear manufacture; kinematics; gear tooth surfaces.
