Tooth-Leap Shaping Method for Helical Gears

Abstract:

In order to reduce cyclic variation in rotational speed of generated gears or shaper cutter induced by additional rotation during shaping, tooth-leap shaping method for helical gears was proposed. Based on fundamentals of helical gears shaping kinematics, principle of tooth-leap shaping for helical gears was introduced. Furthermore, mathematic models of tooth-leap shaping motions for helical gears are established. Finally, several examples are calculated, results show that cyclic variation in rotational speed of generated helical gear can be reduced largely by tooth-leap shaping method comparing with conventional shaping method. Consequently this method will make shaping motions of helical gears more smooth and improve the machining accuracy of helical gears.
