Fatigue failure of a helical gear in a gearbox [PDF]
Engineering Failure Analysis, 2006 This paper presents a failure analysis of a helical gear used in gearbox of a bus, which is made from AISI 8620 steel. The helical gear had been in service about three years when several teeth failed.

Abstract Designers seem to avoid helical and worm gears as being unsuitable and too expensive. A reliable method of selecting gears for a given purpose would result in more frequent applications. The author gives charts and formulas designed to make the computing of spiral gears less difficult.

AbstractIn this paper, a method to determine elastohydrodynamic film thickness in helical gears is developed by combining the DowsonâHigginson elastohydrodynamic lubrication (EHL) formulation with helical gear geometry and kinematics. Comparisons are made with traditional gear film thickness models.

Contact Analysis of Helical Face Gears
Volume 6: 8th International Power Transmission and Gearing Conference, 2000Abstract This paper presents an analytical method developed to design and study the tooth geometry and contact characteristics of helical face gears. The tooth geometry is first defined while simulating the meshing of the face gear with the shaper used to cut it.

Gear Cutting II, Helical Gears
1987We showed in Chapter 14 that two helical gears mounted on parallel axes can mesh correctly together, provided their normal base pitches and transverse base pitches are equal. We can therefore use a helical pinion cutter to cut helical gears, and the normal base pitch and the transverse base pitch of the gear will then be equal to those of the cutter.

In this chapter, the fundamentals of general rigid kinematic pairs are first described and the hyperboloid pitch surfaces are defined. These concepts are then applied to the generation of cylindrical crossed helical gear pairs. The main geometrical quantities of these types of gears are then defined and their kinematic quantities are determined ...
