<p>The gear has multiple planetary wheels (3) provided in contact with a sun wheel (5) and an internal gear (2). Profiles of the sun wheel and the planetary wheels are asymmetrically formed on sides (301, 302, 501, 502) of teeth (300, 500), respectively, where radius of curvature, interference angle, foot radius and/or tooth foot chord of the planetary wheels are asymmetrically arranged at a double meshing between the planetary wheels and the internal gear. Two drive shafts are mounted in a drive-lateral housing part and a drift-lateral housing part, respectively.</p> |
