Abstract
The utility model discloses a loading machine transfer case, comprising a box body, a first gear, a second gear and a third gear. The central lines of the first gear, the second gear and the third gear are at the same plane. The first gear is fixed on the input axis, one end of the input axis is extend out of the box body, the second gear is fixed to the intermediate axle, the third gear is fixed to the output axis, and both ends of the output axis are extend out of the box body. Wherein, the second gear and the third gear are the same size. As three mutually engaged gears are arranged in parallel at the same plane, the loading machine transfer case has simple structure and small power loss, and the utility model is compact and easy to operate. Simultaneously, as the gears are arranged in parallel, the center distance of the gears are large so the power loss is cut down.
