Abstract
The utility model relates to a diesel engine balance shaft cover comprising a flange edge and a shaft-end concave-convex part; the inner side surface and the outer side surface of the flange edge are both planes and the flange edge is provided with an installing hole; the inner surface of the shaft-end concave-convex part is provided with a ring-shaped positioning boss, and the outer surface thereof is provided with a bulge; the connecting part of the surface of the bulge and the outer side surface of the flange edge is a ring-shaped groove; the bottom part of the ring-shaped groove is lower than the outer side surface of the flange edge; and the bulge is not higher than the outer side surface of the flange edge. The diesel engine balance shaft cover is stamped by steel plates and then is processed and molded, thus reducing the cost, having the characteristics of simple processing technique, good rigidity, high strength and the like and being widely applied.
Description
Technical field
The utility model relates to the component of motor, especially diesel engine balance shaft-cup.
Background technique
Engine balance shaft-cup in the market all is cast iron casting mostly, not only manufacturing process complexity, cost height, and this series products poor rigidity, damage easily.The balance shaft-cup that also has some to adopt an extrusion modling of engineering plastics to make, though reduced cost, because the plastics non-refractory, still can not extensive use.Therefore need a kind of cost new product low, that technology is simple, durable to solve the problem of engine balance shaft-cup existence in the market, it can be widely used.
The model utility content
The technical problems to be solved in the utility model is: in order to remedy the deficiency that available engine balance shaft-cup in the above-mentioned background technology exists, provide a kind of with after the steel plate punching press again through machine shaping, cost is low, technology is simple, the diesel engine balance shaft-cup of good rigidly and energy extensive use.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of diesel engine balance shaft-cup, be with after the steel plate punching press again through machine shaping, comprise flange edge and axle head jog, the inner side surface of flange edge and outer side surface are the plane and are provided with mounting hole on flange edges, the internal surface of axle head jog is provided with the ring positioning boss, has projection on its outer surface, the outer side surface joint of this raised surface and flange edge is a toroidal cavity, the bottom of this toroidal cavity is lower than the outer side surface of flange edge, and described projection is not higher than the outer side surface of flange edge.
Further, the ring positioning boss on the internal surface of the toroidal cavity on the outer surface of axle head jog described in the utility model and axle head jog is corresponding mutually.
Further, toroidal cavity described in the utility model is arc surface with the outer side surface of flange edge with projection and is connected excessively.
Further, the internal surface of axle head jog described in the utility model is concordant substantially with the inner side surface of flange edge, consider the punching press influence, internal surface may slightly exceed the inner side surface of flange edge, and the end face of ring positioning boss is that arc surface is connected transition with the inner circle wall of ring positioning boss.
The beneficial effects of the utility model are, the utility model with the steel plate punching press after again through machine shaping, have characteristics such as processing technology is simple, good rigidly, intensity height when having reduced cost, can be used widely.
