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.

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 we will describe the geometry, first of a helical gear meshed with a rack, and then of a pair of helical gears, and in each case we will determine what conditions must be satisfied for correct meshing. We will also discuss how the contact ratio of a pair of helical gears differs from that of a pair of spur gears, and we will show that ...

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 ...

The Kinematics of Crossed Helical Gears
Journal of Mechanical Design, 1982A study is made of the motion of crossed helical gears. Exact expressions are derived for the position of the contact point on each gear and for the sliding velocity, both as functions of gear position. It is shown how to calculate the angular positions of each gear at the beginning and end of contact, and hence the contact ratio.

Fine Blanking of Helical Gears
2015Fine blanking is a well-established process for the production of near net shape components with high quality. The produced parts are characterized by a smooth sheared edge up to 100 %, excellent surface properties with good flatness and little burr as well as close tolerances for near net shape manufacturing. These process characteristics are suitable

In this chapter we will describe the meshing geometry of a pair of helical gears, when their axes are not parallel. Each gear of the pair is an ordinary helical gear, of the type described in Chapter 13. We proved in Chapter 14 that, when two helical gears are mounted on parallel shafts, they must have helix angles ψs that are equal and opposite.

Noise of Involute Helical Gears
Journal of Engineering for Industry, 1969The problem of involute helical gear noise is studied by running a pair of 6 DP gears in a power circulating rig inside an anechoic room. More than 3500 magnetic tape recordings were taken and analyzed, for gears running at different speeds and transmitting different loads.
