Research on Hobbing Process Principles and Linkage Models for Higher-Order Elliptic Gear

Abstract

To solve higher-order elliptic gear manufacturing problems, this paper researches the pitch curves of higher-order elliptic gear and its transmission features, and creates the judgment method whether hobbing process can be applied. The four-axle three-linkage hobbing model for spur gear and the four-axle four-linkage hobbing model for helical gear are built by using tools (inclined) rack based on four-axle linkage strategy. This work provided the theory foundation for the manufacturing modular of higher-order elliptic gear in CNC System.
