Tooth contact analysis of face-gear drives

Based on the face-gear generation process, the analytical geometry of the f ace-gear drive and its mathematical model for tooth contact analysis of the face-gear and the spur pinion meshing were derived. The tooth contact path s and the transmission errors due to assembly error along the axis of face- gear, misalignment of crossed and angular displacements between axes of spu r pinion and face-gear were analyzed. Furthermore, the conditions of underc utting and pointing in the generation process were studied. Several design charts were then developed. Finally, the conditions of undercutting and poi nting for a face-gear drive were all identified in meshing with and without assembly error along the direction of the axis of face-gear and misalignme nt of angular displacement between axes of spur pinion and face-gear. Sever al numerical examples were also presented. (C) 1999 Elsevier Science Ltd. A ll rights reserved.
