Helical Gears Geometry of helical gears and gear meshes

Geometry of helical gears and helical gear meshes is reviewed. Helical gears have similarities with spur gears, but fundamental differences do exist. A helical gear is similar to a spur gear with an applied twist along its axial axis. This notebook reviews geometric attributes of helical gears and their significance to helical gear mesh operation.
