Abstract
The utility model provides a connecting structure for an air cylinder block and a main bearing cover, which belongs to the technical field of an engine. The connecting structure solves the problems of low positioning accuracy, whole rigidity and strength reduction and complex process which are caused by respect processing of the connecting surfaces for the main bearing cover and the cylinder block. The connecting structure for the cylinder block and the main bearing cover comprises a semicircular connecting part I on the cylinder block and a semicircular connecting part II on the main bearing cover, wherein the connecting part I and the connecting part II are mutually connected between the cylinder block and the main bearing cover to form a round mounting hole for placing a main shaft, a plurality of concavo-convex embedding pieces I are arranged on the connecting part I, and embedding pieces II with the position corresponding to that of the embedding pieces I and the shape matched with that of the embedding pieces I are arranged on the connecting part II. The cylinder block is directly meshed with the main bearing cover, and other accurate positioning methods are not required, so that the design process is simplified.
Description
Technical field
The utility model relates to technical field of engines, the linkage structure of particularly a kind of cylinder block and main bearing cap.
Background technique
At present, engine cylinder main bearing cap and engine cylinder be casting and processing respectively respectively normally, and main bearing cap is connected on the cylinder block by bolt.As the disclosed patent documentation of State Intellectual Property Office of the People's Republic of China [patent No.: ZL200720123893.4], a kind of engine cylinder-body and crankshaft main bearing pedestal linkage structure, include cylinder body and crankshaft main bearing pedestal, they connect by bolt, the crankshaft main bearing pedestal main body falls into cylinder body counterpart groove, is connected with cylinder body by two bolts.This Placement processing technology is loaded down with trivial details, and the junction surface of main bearing cap and cylinder block all will process respectively, influenced by parting surface and bolt hole machining error etc., causes the location accurate inadequately, and integral rigidity, intensity all descend to some extent.
Summary of the invention
The purpose of this utility model is at existing technical problem, and it is simple to propose a kind of manufacturing, and assembling is accurate, the cylinder block that adhesive strength is high and the linkage structure of main bearing cap.
The purpose of this utility model can realize by following technical proposal: the linkage structure of a kind of cylinder block and main bearing cap, this linkage structure comprises having on the cylinder block to have semicircular joint two on semicircular joint one and the main bearing cap, joint one interconnects between with joint two and forms the circular mounting hole of putting for main shaft, it is characterized in that, have chimeric of some concave-convex surfaces on the described joint one, have on the described joint two and chimeric one position is corresponding and shape is complementary chimeric one.
Main shaft rotates in a circumferential direction in the circular mounting hole, chimeric two impact force that will bear main axis rotation inertial force to it on the joint one chimeric one and the joint two.So in order to guarantee the steady running of motor, chimeric one and chimeric 's two quality of fit wants high, it is enough big that rigidity is wanted, and vibrates and noise otherwise can cause motor to produce because of the degree of adaptability difference of cylinder block and main bearing cap.
In the linkage structure of above-mentioned cylinder block and main bearing cap, described chimeric one and chimeric two is fracture surface.The advantage of fracture surface is utilized the fracture back to form rough crackle exactly on fracture surface and is directly meshed, because engagement degree height need not other accurate localization modes, does not also need cylinder block and main bearing cap fitting surface are further processed.
As another scheme, in the linkage structure of above-mentioned cylinder block and main bearing cap, described chimeric one and chimeric two is teeth.
In the linkage structure of above-mentioned cylinder block and main bearing cap, described cylinder block and main bearing cap are formed by integrally casting.It is disconnected to rise after casting again, forms fracture surface.Rising has no progeny can directly accurately mesh, and than tratitional technology, cylinder block, main bearing cap integral rigidity, reduction in strength that rising has no progeny assembles again are minimum.
Behind cylinder block and main bearing cap integrally casting, the assembling again of having no progeny of rising.Its advantage is:
1, main bearing cap and cylinder block directly rise and have no progeny, and have saved the processing to cylinder block and main bearing cap fitting surface, needn't design the fitting surface tolerance, shorten process time, have avoided the influence of fitting surface machining error to the main bearing cap assembling simultaneously.
2, since the directly engagement of assembling of having no progeny of rising need not other accurate localization modes, thereby simplified design process.
3, than tratitional technology, cylinder block, main bearing cap integral rigidity, reduction in strength that rising has no progeny assembles again are minimum.

Fig. 2 is a structural representation of the present utility model.
Among the figure, 1, cylinder block; 2 main bearing cap; 3, joint one; 4, joint two; 5, circular mounting hole; 6, chimeric one; 7, chimeric two; 8, crackle; 9, bolt of main bearing cap.
Embodiment
As shown in Figure 1 and Figure 2, the linkage structure of this cylinder block 1 and main bearing cap 2 comprises having on the cylinder block 1 to have semicircular joint 24 on semicircular joint 1 and the main bearing cap 2.Joint 1 interconnects between with joint 24 and forms the circular mounting hole 5 of putting for main shaft.Cylinder block 1 and main bearing cap 2 are formed by integrally casting, and it is disconnected to rise along the cross central line in circular mounting hole 5, and rising has no progeny is divided into joint 1 and joint 24.
Have chimeric 1 of some concave-convex surfaces on the joint 1, have corresponding on the joint 24 with chimeric 1 position and shape is complementary chimeric 27.Chimeric 1 and chimeric 27 is fracture surface, has rough crackle 8 on the fracture surface.Utilize corresponding crackle 8 directly to mesh, accurately locate, need not other accurate localization modes can directly assemble.Cylinder block 1 and main bearing cap 2 are fixed together by bolt of main bearing cap 9.
When engine running, main shaft is subjected to the composite force from all directions, acting on advocating on the main bearing cap 2 will be born by bolt of main bearing cap 9, but horizontal a part of power can be relayed to by chimeric 27 of main bearing cap 2 on the cylinder block 1 chimeric 1.So just share the power that bolt of main bearing cap 9 is born, increased the working life of bolt of main bearing cap 9, improved its durability and reliability.
