Involute Helical-bevel Gearing

AbstractThis paper describes helical-bevel gearing (HBG). The helical-bevel gearing commonly includes a cylindrical and a bevel gear. The tooth profiles can be either spur or helical. The involute HBG provides an opportunity to design a broad variety of gear trains, unobtainable by the use of conventional types of gears. The article defines methods of their generation, a contact shape and points out advantages of various arrangements of gears, diagrams of an external helical-bevel gearing skew axis, hypoid gearing, intersecting axes, parallel axes. The expediency of the use of such gear in a machine drive is justified
