Abstract: To study contact characteristics of the curve-face gears, a transmission coordinate of curve-face gears was established. The instantaneous rotation axis and the axode of the curve-face gear were derived. The calculation method of meshing point of line contact curve-face gear was obtained based on the fundamental theorem of meshing tooth profile. The tooth contact prints and the tooth profile points were obtained in the view of geometry. The results of tooth contact analysis of the curve-face gear show that the positions of profile modification are determined. The calculation method of meshing point of line contact curve-face gear pair was verified via rolling experiments.

Key words: curve-face gear, tooth contact, axode, variable transmission ratio, line contact
