Spur gear nomenclature
A spur gear has a cylindrical pitch surface and teeth that are parallel to the axis. WebThe basic geometry and nomenclature of a spur gear mesh is shown in Figure 2-1. The essential features of a gear mesh are: Center distance. The pitch circle diameters (or pitch diameters). Size of teeth (or module). …

Helical gears are used in two forms: Parallel shaft applications, which is the largest usage. Crossed-helicals (also called spiral or screw gears) for connecting skew shafts, usually at right angles. 6.1 Generation Of The Helical Tooth
WebHelical gear (nomenclature). herringbone gears) are used. It is equivalent to two single helical gears, in which equal and opposite thrusts are provided on each gear and the resulting axial thrust is zero. 29.2 Terms used in Helical Gears The following terms in connection with helical gears, as shown in Webvirtual spur gear having the same properties as the actual helical gear. The virtual number of teeth Nʹ may be expressed in the following convenient form: N is the number of actual teeth. 257 It is necessary to know the virtual number of teeth in design: This is considered in finding the appropriate values of the geometric factors Y ...
