Web1 dag geleden · Gear ratio is the ratio between the numbers of teeth in mating gears. Helical overlap is the effective face width of a helical gear divided by the gear axial pitch. Helix angle is the angle that a helical gear tooth makes with the gear axis at the pitch circle, unless specified otherwise. Hertz stress, see Contact stress. An external gear is one with the teeth formed on the outer surface of a cylinder or cone. Conversely, an internal gear is one with the teeth formed on the inner surface of a cylinder or cone. For bevel gears, an internal gear is one with the pitch angle exceeding 90 degrees. Internal gears do not cause output shaft direction reversal.
