Abstract
The utility model discloses a cylinder block of a diesel engine, which comprises a cylinder block body and a crankshaft, wherein a bearing seat and a bearing cover used for supporting the crankshaft are arranged in the cylinder block body, the bearing seat and the bearing cover are respectively provided with a push stop piece at two side surfaces relative to the crankshaft so as to form push strop structures, the push stop piece is in a semi-ring shape, each side surface is provided with two push stop pieces to form a complete ring, and the two push stop structures are arranged in the cylinder block. Compared with the prior art, the cylinder block can effectively prolong the service life of the push stop piece, reduces the wear to the crankshaft, and further reduces the failure rate of the diesel engine.
Description
Technical field
The utility model relates to a kind of cylinder of diesel engine, relates in particular to a kind of thrust mark structure of cylinder of diesel engine.
Background technique
In cylinder of diesel engine, not only bent axle also can be because of contacting and do the caused by relative motion friction with bearing cap with bearing support at the cross-wise direction axle journal of axle journal because of contacting and do the caused by relative motion friction with bearing cap with bearing support on the axial outer peripheral surface of axle journal.In order to prevent destruction bent axle because of friction, the technician installs thrust plate on two surface of contact of bearing support and bearing cap and axle journal side, and with installation position fine finishing, form thrust retaining structure, to reduce friction, and prevent the infringement that causes because of direct friction between axle journal side and bearing support and the bearing cap, thereby the working life of improving diesel engine.
But the technician finds in practice, even after installing thrust plate, because thrust plate is easy to wearing and tearing, causes diesel engine often to break down, must running check and change thrust plate.
The model utility content
The technical problems to be solved in the utility model is to provide a kind of cylinder of diesel engine, and this block structure can reduce the fault that causes because of the mutual wearing and tearing between crankshaft journal side and bearing support and the bearing cap effectively.
For solving the problems of the technologies described above, the utility model provides a kind of cylinder of diesel engine with following structure:
A kind of cylinder of diesel engine, comprise cylinder block body and bent axle, be provided with a plurality of bearing support and bearing caps that support described bent axle that are used to install in the described cylinder block body, described bearing support is separately installed with thrust plate to form thrust retaining structure with bearing cap on two sides relative with bent axle, described thrust plate is semi-annular shape, two described thrust plates are installed on each side and are formed a complete annulus, be provided with two described thrust retaining structures in the described cylinder block.
Preferably, described two thrusts retaining structure is arranged at respectively on adjacent two bearing supports and the bearing cap.
Preferably, described two thrusts retaining structure is identical.
Compared with prior art, cylinder block described in the utility model can effectively improve the working life of thrust plate, and has reduced the wearing and tearing to bent axle, and then has reduced the rate of fault of diesel engine.
Description of drawings
Fig. 1 is the thrust structural representation of cylinder block in the prior art;
Fig. 2 is the thrust structural representation in the utility model cylinder block.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subjected to the restriction of embodiment.
As prior art, cylinder of diesel engine comprises cylinder block body and bent axle, is provided with in the described cylinder block body to be used to install bearing support and the bearing cap that supports described bent axle.Diesel engine when work, bent axle not only on the outer peripheral surface of axle journal because of contacting and do the caused by relative motion friction with bearing cap with bearing support, also can be at the cross-wise direction axle journal of axle journal because of contacting and do the caused by relative motion friction with bearing cap with bearing support.In order to prevent destruction bent axle because of friction, the technician installs thrust plate on two surface of contact of bearing support and bearing cap and axle journal side, and with installation position fine finishing, form the thrust structure, to reduce friction, and prevent direct friction between axle journal side and bearing support and the bearing cap, thereby the working life of improving diesel engine.
Fig. 1 is that described prior art is ended the selection structure schematic representation, on two relative sides of bearing support 4 and bearing cap 2 and bent axle 3, be separately installed with thrust plate 1 to form the thrust structure, described thrust plate 1 is semi-annular shape, two described thrust plates 1 is installed on each side and is formed an annulus of finishing.But find that in practice thrust plate 1 is easy to wearing and tearing, causes diesel engine often to break down, must running check and change thrust plate 1.Test discovery repeatedly through the technician, the reason that wearing and tearing take place thrust plate 1 easily is that bent axle is in rotation, and string is moving about can producing; When automobile brake, bent axle 3 is subjected to thrust forward, and this need bear these thrust by the thrust surface that bent axle 3 and thrust plate 1 form.Crankshaft thrust face and thrust plate surface at bearing thrust, owing to can't form oil film, through using for a long time, just produced wearing and tearing, in case inordinate wear occurs, whole thrust plate 1 grinds off soon, produce bent axle 3 and bearing support 4 direct contact frictions, destroy bent axle 3 and body, cause motor not work, complete machine is scrapped.
So the inventor expects such solution, increase by one second thrust shelves 6, promptly on the basis of the first thrust shelves 5 that have been provided with, on an other bearing support 4 and bearing cap 2, thrust plate 1 is installed.Test through the research staff proves that such structure makes the thrust area double, and the specific pressure that is subjected to impact force just reduces half, and wearing and tearing will significantly reduce.The quantity of thrust structure simultaneously, is the best with two.
The cylinder block of above-mentioned pair of thrust structure can improve the working life of thrust plate 1 effectively, and has reduced the wearing and tearing to bent axle 3, and then has reduced the rate of fault of diesel engine.This structure is this best to the bigger type effect of thrust surface impact force to dumping car etc., requires the low type of rate of fault also can use to those.
More than disclosed only be a specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
