The conical involute gears have been applied to automotive parts such as FR-4WD transfer. To apply for automobile, high capacity and higher quietness are required. However the tooth contact of conical gear pair is point contact, so the large ease off happens even though each tooth surface has no manufacture error. Also the tooth depth and thickness of conical involute gears change along the lead direction. These characteristics have to be considered for the tooth mesh analysis. This paper proposes a simulation method for calculating the relative tooth surface form that is called ease-off. It also describes an improved method of estimating the tooth mesh compliance that takes into account the change of tooth shape. With these methods, we can accurately analyze the transmission error of a conical gear pair as well as a cylindrical gear pair.
