Abstract

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, particularly those correlated with the lengthwise sliding and sliding velocity. Subsequently, the load analysis of this gears is performed and the thrust characteristic on shafts and bearings are defined. Other important kinematic quantities related to the rolling and sliding motions of the mating teeth surfaces are then defined and the instantaneous and average efficiencies of these gears are analytically determined. Finally, short notes are given regarding the fundamentals of profile-shifted toothing for crossed helical gears.
