Crossed Helical Gears

  • J. R. Colbourne

Abstract

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. We will now show that two helical gears whose helix angles are not equal and opposite can be mounted on non-parallel shafts, and that, provided certain conditions are met, the angular velocity ratio of the two gears will remain constant.
