Abstract
In this chapter, the main types of gearing used in practical applications for transferring power between parallel, intersecting and crossed axes are described. The tooth parts and some quantities that characterize the toothing are also described and defined. The first law of gearing to be met to have a constant transmission ratio is also recalled, and the main geometric and kinematic parameters of gear drives, gear pairs, and gear wheels are defined. The geometrical parameters concerning the toothing and its sizing are expressed in terms of transverse module, but indications are given to express them in terms of transverse diametrical pitch. Moreover, the ranges of the reference values of efficiency obtainable with the various types of gears are provided, with indications for reaching the maximum values. Finally, attention is focused on the parameters that define the precision of the teeth and the accuracy grade of the gears, highlighting their influence on the transmission error, under static and dynamic conditions.
