ABSTRACT

Transmission and transformation of a rotation from a driving shaft to a driven shaft is the main purpose of intersected-axes gears. The known designs of the earliest intersected-axes gear pairs indicate strong constraints imposed by the gear technology available at that time for the production of gears. This chapter provides an implementation for an internal intersected-axes gear pairs in the design of a nutation drive. It discusses the tooth flanks of perfect intersected-axes gear pairs. An analysis of the vector diagrams for intersected-axes gearing reveals that the rotation vectors, ωg and ωp, of the gear and pinion are not parallel to the vector of instant rotation, ωpl. Therefore, axial sliding of the tooth flanks of the gear, G, and pinion, P, is inevitable in intersected-axes gearing of all kinds.
