Abstract

A calculation formula of boundary size is proposed to analyze the conjugate meshing of nutation face gear transmission by using the condition of no tip change and root undercutting. Furthermore, the influence of tooth shape design parameters on the boundary dimension of nutation face gears is studied. Based on the meshing principle of spacial gears, the conjugate conditions of the “face-face” gear pair are derived, the calculation method of discrete points of tooth surface is given, and the three-dimensional model of the nutation face gear transmission device is also established, which helps the design and manufacturing of high-quality nutation face gear transmissions and improves its transmission performance.
