Transmission errors and bearing contacts of a curvilinear-tooth gear under different assembly conditions are investigated by applying the tooth contact analysis and the surface topology methods. Four numerical examples are presented to illustrate the influence of gear assembly errors on transmission errors and the directions and orientations of the contact ellipses. The numerical results reveal that the transmission error of the curvilinear-tooth gear pair is small and the bearing contacts are located in the middle region of the curvilinear-tooth surface even under axial misalignments.

A rack cutter with a curved-tooth is considered the generating tool for the generation of the proposed gear, and a mathematical model of cylindrical gears with curvilinear shaped teeth is developed according to the gearing theory. The developed computer program can develop profiles of the curvilinear-tooth gear with point contacts. The developed gear tooth mathematical model is used to investigate the tooth undercutting of curvilinear-tooth gears via differential geometry and the numerical method. (C) 2001 Elsevier Science Ltd.
