Design and geometry of face-gear drives

WebMar 13, 2024 · A design method of low sliding ratio face gear drive is presented. The rack and gear meshing pair with a low sliding ratio is obtained by constructing the contact path. WebFace gears belong to the class of bevel gears, and can be thought of as a limiting case, with cone angle 0° (pinion) and 90° (face gear). The strength calculation for bevel gears is conducted on the basis of an equivalent spur/helical gear, the spur/helical having the same tooth form as the bevel.
