ABSTRACT:
A gearbox (1) is formed by two steel plates (3,5) which support molded elements (such as 13b and combined 35e, 33e). A separate molding operation is performed on each plate, in which a plurality of individual molded parts are molded. The precise positioning is from the mold, not the plate. The liquid plastic is bound to the plate by entering a plurality of holes (such as 66 and 66a) for each part. The plates are then populated and then held together by screws (72a-72d). A bevel gear (31) is mounted on the outside by molded supports (29a, 29b) and by contact with gear (36) with which it meshes.
