A gearbox case body and a composite molding process thereof, the case body includes a front case body and a rear case body fixedly connected with the same structure, the two are connected to form a gearbox cavity, and a power input cavity in the cavity is formed. The central axis of the cavity is located in the vertical symmetry plane of the cavity, and the distance from the central axis of the output cavity in the horizontal direction of the box is smaller than the distance in the vertical direction of the box, and a bar-shaped reinforcement is arranged on the inner wall of the reinforcement cavity; The gearbox casing has a compact and simple structure, and has reliable mechanical strength, and the composite molding process utilizes coated sand to form the cavity of the casing and performs heat treatment of the casting, so that the forming casing has a clear configuration and high quality consistency.
Description
technical field [0001] The present application relates to a gear box body and a molding method thereof, in particular to a gear box body and a composite molding process thereof. Background technique [0002] The gearbox is a gear transmission component that transmits power through the transmission gear train. It has the functions of changing speed, changing the direction of transmission and changing the rotational torque; according to needs, the gearbox can also have the function of clutch, by separating two originally meshed gears , to achieve the purpose of separating the engine from the load. The design of the gearbox case should be carried out in accordance with the layout arrangement of the power transmission, the processing and assembly conditions, and the requirements for easy inspection and maintenance. In order to pursue easy molding, some existing gearboxes have a smooth inner wall. Although the mechanical strength of the existing gearbox can be satisfied, the tem...
