Abstract
The utility model discloses a general gasoline engine lightweight box body. A crankshaft cavity and a crankshaft installation hole bearing base are arranged on the box body. Only two reinforced ribs connected with the wall of the crankshaft cavity and the crankshaft installation hole bearing base are arranged on the bottom large plane of the crankshaft cavity. A boss I connected with a supporting oil tank is arranged on the outer wall of the box body, and a weight reduction groove is arranged on the boss I. By aid of measures of removing redundant reinforced ribs on the bottom surface of the crankshaft cavity, arranging the weight reduction groove on the boss I which is connected with the supporting oil tank and the like, the weight of the general gasoline engine lightweight box body is reduced under the condition of having the strength required by the design, and accordingly manufacture materials are saved and manufacture cost is reduced.
Description
Technical field
The utility model relates to a kind of casing, particularly a kind of all-purpose gasoline box body.
Background technique
The all-purpose gasoline box body is provided with crankcase and cylinder body, in Gasoline Engine Working Process, need bear bigger impact force.Original petrol engine casing is too much its intensity of emphasis in design, so that original all-purpose gasoline box body is provided with too much stiffening rib, causes the casing consume material more, and fabricating cost is higher.
Therefore need improve all-purpose gasoline box body of the prior art,, alleviate box weight, practice thrift fabricating cost to remove its redundant reinforcing rib structure.
The model utility content
In view of this, the purpose of the utility model provides a kind of general gasoline engines lightweight casing, and reinforcing rib structure is reasonable in design on its casing, and box weight is lighter, and fabricating cost is low.
The utility model general gasoline engines lightweight casing, casing are provided with crankshaft cavity and crankshaft installed hole bearing support, only are provided with two stiffening ribs that connect crankshaft cavity wall and crankshaft installed hole bearing support on the big plane, the bottom of said crankshaft cavity.
Further, said cabinet exterior is provided with one and connects the boss I that supports fuel tank, and said boss I is provided with the loss of weight groove;
Further, also be provided with the boss II of a connection support flying wheel protective housing on the said casing, said boss II is arranged on the casing with cantilevered fashion.
The beneficial effect of the utility model: the utility model general gasoline engines lightweight casing; Through the redundant stiffening rib on the bottom surface of removing crankshaft cavity be connected measures such as the loss of weight groove is set on the boss I that supports fuel tank; Its own wt under the condition with designing requirement intensity is alleviated; Thereby practiced thrift manufactured materials, reduced manufacture cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Fig. 1 is the crankshaft cavity internal structure schematic representation of the utility model general gasoline engines lightweight casing;
Fig. 2 is the boss I bilge construction schematic representation of the utility model general gasoline engines lightweight casing;
Fig. 3 is the boss II bilge construction schematic representation of the utility model general gasoline engines lightweight casing.
Embodiment
Fig. 1 is the crankshaft cavity internal structure schematic representation of the utility model general gasoline engines lightweight casing; Fig. 2 is the boss I bilge construction schematic representation of the utility model general gasoline engines lightweight casing; Fig. 3 is the boss II bilge construction schematic representation of the utility model general gasoline engines lightweight casing.
As shown in the figure, present embodiment general gasoline engines lightweight casing, casing are provided with crankshaft cavity and crankshaft installed hole bearing support 1, only are provided with two stiffening ribs 2 that connect crankshaft cavity wall and crankshaft installed hole bearing support 1 on the big plane, the bottom of said crankshaft cavity.Present embodiment general gasoline engines lightweight casing, the redundant stiffening rib through on the bottom surface of removing crankshaft cavity is alleviated its own wt under the condition with designing requirement intensity, thereby has practiced thrift manufactured materials, can reduce manufacture cost.
As the improvement to this embodiment, said cabinet exterior is provided with one and connects the boss I 3 that supports fuel tank, and said boss I 3 is provided with loss of weight groove 4.Through on the boss I 3 that connects the support fuel tank, the loss of weight groove being set, making it under condition, can further alleviate the casing own wt, practice thrift manufactured materials, thereby manufacture cost is further reduced with designing requirement intensity.
As improvement to this embodiment, also be provided with the boss II 5 of a connection support flying wheel protective housing on the said casing, said boss II 5 is arranged on the casing with cantilevered fashion; Cantilever type boss II 5 has been cancelled the supporting rib stiffener in the original structure, thereby a step casing alleviates own wt, practices thrift manufactured materials again, and reduce again by a step for the casing manufacture cost.
Explanation is at last; Above embodiment is only unrestricted in order to the technological scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technological scheme of the utility model; And not breaking away from the aim and the scope of the utility model technological scheme, it all should be encompassed in the middle of the claim scope of the utility model.
