... 3D-space. A gear drive formed by a helical gear and a worm gear is
a particular case of a gear drive with crossed axes (Figure 16.1.2). Gear tooth surfaces
are in line contact for involute helical gear ... canonical design discussed for nonstandard
gears can be applied as well for the design of standard crossed helical gears.
