FIELD: transport. ^ SUBSTANCE: proposed gearbox comprises housing, central shaft, bevel gear, main gear, reverse gear, two planetary gears and couplings. Main gear comprises inner gearing wheel engaging with gear. Wheel outer cylindrical surface accommodates shoe with mating cylindrical surface and chamfer that makes wedge gap between interacting surfaces of shoe and wheel. Said shoe is locked by screw arranged so that its geometrical axis divides shoe surface into two unequal parts the greater of which fairs with said chamfer. ^ EFFECT: reduced losses in inner gearing main gear, dimensions and weight. ^ 2 dwg |
