Research on Plasticity Shaped Technology of Rear Axle Gear of Motorcar

Abstract:

Rear axle spiral bevel gear of motorcar, as its special shape structure , alveolar much deeper than straight bevel gear , and has spiral angle effect , therefore, extrusion of rear axle gear than extrusion of straight bevel gear is much more difficult , deal with the problems, have made closed extrusion new technology of rear axle gear , designed new type die structure, die adopt fluctuateing concave model level bisection ， pre-stressed composite concave model structure , concave model and model core floating , parts have no fly side , tooth surface can reach the level of rough milling ,higher production efficiency and life of die , satisfied production requirements. Process test showed that compared with the open die , required extrusion distortion force reduced 50% , increase material utilization 15%, debase electric power consumption 50%, with significant economic benefits .
