...Yi-Hui Lee; Zhang-Hua Fong A highly accurate digital-twin spiral bevel gear or hypoid gear is often required for dynamic analysis or stress analysis for gear transmission. However, a highly accurate digital-twin solid model is not always available because the final hypoid gear is completed...

...Yi-Hui Lee; Zhang-Hua Fong Cutter head with multiple stick blades is widely used in the mass production of hypoid and spiral bevel gears because they allow more blades per revolution of the head cutter. However, the stick blade geometry for a head cutter that is used in face-milling and face...

...Pei-Yu Wang; Sih-Ci Fan; Zi-Gui Huang A significant portion of the research on spiral bevel gear focused on contact stress and assembly flexibility (V and H check) values, while only a few studies investigated the relationship between transmission errors and rotational speed. This paper addresses...

...Ligang Yao; Bing Gu; Shujuan Haung; Guowu Wei; Jian S. Dai The purpose of this paper is to propose a pair of external and internal spiral bevel gears with double circular-arc in the nutation drive. Based on the movement of nutation, this paper develops equations of the tooth profiles for the gear...
