This paper presents the procedure to simulate the transmission error in a planetary gear of star type. A planetary gear system is a kind of constrained geartrain. Accordingly a number of gear meshes between planet gears and a sun gear or a ring gear affect each others. Therefore a coupled analysis method of the transmission error is developed. Then this method is applied to study the effects of mesh phasing and tooth surface error on the transmission error and mesh excitation force. As a result, a sequential phasing has a great advantage for reducing transmission error and mesh excitation force compared with a simultaneous phasing. This effect is expected when planet gears have different tooth surface errors from one another as well as homogeneous tooth surface error.
