Abstract
The utility model discloses a crankcase with a imbedding structure, which comprises a case body, the case body is provided with a plurality of main bearing holes, and bearing seat imbedding blocks are abreast imbedded on the main bearing holes of the case body. The crankcase with imbedding structure supports main bearing load by arranging the bearing seat imbedding blocks, the case body does not bear the main bearing load, then complex reinforcing ribs do not need to be arranged, and then can avoid the increased complexity of casting technique and the increased cost . Meanwhile, the case body adopts aluminium materials to achieve the effects of weight reduction and easy sealing. The utility model can be widely applied to various light diesel engines and gasoline engines with higher combustion pressure.
Description
Technical field
The utility model relates to a kind of engine crankcase, relates in particular to a kind of crankcase of castingin structure.
Background technique
The motor unit mass power that the design of LD-diesel and petrol engine is at present all had relatively high expectations, so the selection of engine component material is particularly crucial, lightweight, environmental protection, economic material more and more are widely used.As the key components and parts of engine design, crankcase material also more and more adopts the simpler aluminum material of the lighter casting technique of material to replace traditional cast iron materials.But conventional aluminium material mechanical strength is accompanied by improving constantly of engine combustion pressure not as good as the cast iron class, and the crankcase of conventional aluminium material can not satisfy strength demand.The design of crankcase should be satisfied the requirement that intensity improves constantly, and satisfies lighter, more economical requirement again, and this itself is exactly a pair of insoluble contradiction.
The model utility content
The purpose of this utility model is, can not satisfy simultaneously that intensity improves and the defective of the lighter more economical requirement of quality at engine crankcase in the prior art, and a kind of crankcase of castingin structure is provided.
The crankcase of this castingin structure comprises casing, and casing is provided with some main bearing holes, and castingin has bearing support to insert side by side on the main bearing hole of casing.
The surface of contact that described bearing support is inserted with described casing is provided with block.
Described bearing support is inserted and be provided with the casting technique hole on described main bearing hole is axial.
Described bearing support is inserted and is provided with the thrust surface concordant with described casing.
Described bearing support is inserted upward, and bilateral symmetry is provided with the Main bearing bolt hole.
Described bearing support is inserted and is made by vermicular graphite iron material.
The crankcase of castingin structure of the present utility model inserts supports main shaft to carry lotus by bearing support is set, casing does not bear the main bearing load substantially, therefore the stiffening rib that does not need complicated layout, can avoid like this increasing the complexity of casting technique and raising the cost, casing adopts aluminum material simultaneously, falls effect heavy and easy sealing to reach.The utility model can be widely used in various LD-diesel and have the petrol engine of higher firing pressure.

Embodiment
The present invention is described in detail below in conjunction with accompanying drawing.
With four cylinder light-duty diesel engine crankcase structures is that example is described the utility model, as shown in Figures 1 to 4, on the main bearing hole 2 of casing 1 side by side castingin have bearing support to insert 3.Bearing support is inserted and 3 is provided with block 5 with the surface of contact of casing 1, be used for increasing bearing support insert 3 with the adhesion of main bearing hole 2 inwalls.Bearing support is inserted and 3 is provided with casting technique hole 6 at described main bearing hole 2 on axially, increase bearing support insert 3 with the combination force of casing 1.Described bearing support is inserted and 3 is arranged with two bearing bolt holes 7, the bearing support impacting force and the main bearing load of 3 spring bearing bolts of inserting in use, and casing 1 does not bear the main bearing load substantially.Bearing support 3 thrust surfaces 4 and casing 1 processing of inserting is concordant, to support the end thrust of bent axle.
Because the crankcase castingin of present embodiment has bearing support to insert, therefore casing is not loaded by main bearing substantially, does not need the stiffening rib of complicated layout, and avoiding increases the complexity of casting technique and raise the cost, casing adopts aluminum material simultaneously, falls effect heavy and easy sealing to reach.Bearing support is inserted and casing adopts different materials, and bearing support is inserted and adopted the material of the setting temperature with better mechanical property and Geng Gao, as vermicular cast iron.So both can reduce the quality of crankcase, and also make the intensity of crankcase improve.
The utility model can be widely used in various LD-diesel and have the petrol engine of higher firing pressure.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technological scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technological scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
