Basic Equations of the Hypoid Dimension Design for Duplex Cutting

The hypoid gear has had wide-spread use in industrial fields, but there has been no discussion about accurate design methods. for obtaining a satisfactory hypoid tooth form, some kinds o f cutting machines have been made, with individual hypoid design and production system. On the other hand, hypoid gear dimensions cannot be confirmed in the production, and the measuring systems are just their running test with the mating gear. sometimes, plant engineers are quite confused by the hypoid noise trouble. This paper discusses the relationships between the hypoid dimensions and depthwise tooth taper for duplex cutting, and makes it possible to design accurate enough gear dimensions for designing and gear cutting.
