Contact characteristics of spherical gears

In this paper, the theory of gearing and the proposed mechanism of spherical gear cutting are applied to develop the mathematical model of spherical gears. Based on the developed mathematical model of spherical gears, computer graph of the gear set is plotted, and tooth contact analysis (TCA) of spherical gear sets is also performed. The TCA results provide useful information about the kinematic errors (KEs), contact ellipses and contact patterns of spherical gear sets.
