Abstract
The utility model discloses an improved housing structure of a diesel engine, which comprises a left box body, a right box body, a cylinder and a cylinder head, wherein the cylinder and the left box body adopt a split type structure. The improved housing structure of the diesel engine greatly reduces the complexity and production cost of casting moulds of the left box body and the cylinder as the two are separately arranged as two parts, and leads the two to be processed more easily. Furthermore, with the adoption of the improved housing structure, if being worn, the cylinder needs to be replaced independently without replacement thereof together with the left box body like the prior art, so that the maintainability of the housing of the diesel engine is greatly improved.
Description
Technical field
The utility model relates to a kind of improved shell structure of diesel engine.
Background technique
As shown in Figure 1, the shell construction of diesel engine is divided into left box body 1, right case 2, cylinder 3 and 4 four parts of cylinder head usually in the prior art, wherein cylinder 3 and left box body 1 cast solid, cylinder head 4 then is fixed on the left box body 1 by some bolts (not marking among the figure).The shortcoming of this kind shell construction is: because cylinder 3 and left box body 1 cast solid cause the casting mould of left box body 1 bulky, and complex structure, die cost is higher; And existing diesel engine housing must be in company with changing whole left box body 1 when cylinder 3 wearing and tearing, and maintenance cost is also higher.
Summary of the invention
The utility model purpose is: provide a kind of processing simple, make and the lower improved shell structure of diesel engine of maintenance cost.
The technical solution of the utility model is: a kind of improved shell structure of diesel engine, comprise left box body, right case, cylinder and four parts of cylinder head, and described cylinder and left box body adopt split-type structural.
Further, cylinder head is positioned at cylinder upper described in the utility model, and together is fixed on the left box body by some stud bolts with cylinder.During concrete the installation, the screw rod of described stud bolt passes the positioning hole that cylinder head, cylinder and left box body are provided with successively, thereby two ends are fixed together cylinder head, cylinder and left box body three by fastening nut, and promptly the cylinder in the utility model is clamped between cylinder head and the left box body.
Further, cylinder described in the utility model and left box body are all around also by some single ended bolt or screw, to guarantee the sealing between cylinder and the left box body.During concrete the installation, be example with the single ended bolt, its screw rod passes the positioning hole that is provided with around cylinder and the left box body successively, thereby an end makes the more firm of cylinder and left box body combination by fastening nut, and guarantees both sealings.
Fix by some screws or bolt with routine techniques is the same between the left and right casing described in the utility model.
The utility model has the advantages that:
This improved shell structure of diesel engine that the utility model provides, because left box body and cylinder are divided into two parts, so greatly reduce their complexity and manufacture costs of casting mould separately, it is simpler that left box body and cylinder are processed.And if the utility model then only needs to change cylinder separately in use cylinder wear, need not as prior art to have improved the maintainalbility of diesel engine housing greatly together with the replacing left box body.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is an existing diesel shell construction schematic representation;
Fig. 2 is the utility model improved shell structure of diesel engine schematic representation (omitting the nut in stud bolt and the single ended bolt).
Wherein: 1, left box body; 2, right case; 3, cylinder; 4, cylinder head; 5, stud bolt; 6, single ended bolt.
Embodiment
Embodiment: as shown in Figure 2, this improved shell structure of diesel engine that the utility model provides comprises left box body 1, right case 2, cylinder 3 and 4 four parts of cylinder head, and wherein said cylinder 3 adopts split-type structural with left box body 1.Cylinder head described in the present embodiment 4 is positioned at cylinder 3 tops, and together be fixed on the left box body 1 by four stud bolts 5 with cylinder 3, during concrete the installation, the screw rod of described stud bolt 5 passes the positioning hole that cylinder head 4, cylinder 3 and left box body 1 are provided with successively, two ends by fastening nut (omitting among the figure) thus cylinder head 4, cylinder 3 and left box body 1 three are fixed together, promptly the cylinder in the utility model 3 is clamped between cylinder head 4 and the left box body 1.Simultaneously described cylinder 3 is also fixing by two single ended bolt 6 all around with left box body 1, during concrete the installation, the screw rod of single ended bolt 6 passes the positioning hole that is provided with around cylinder 3 and the left box body 1 successively, one end by fastening nut (omitting among the figure) thus make cylinder 3 and left box body 1 combination more firm, and guarantee both sealings.Then fixing between left box body 1 and the right case 2 by screw (omitting among the figure).
This improved shell structure of diesel engine that the utility model provides because left box body 1 and cylinder 3 are divided into two parts, so greatly reduce their complexity and manufacture costs of casting mould separately, makes left box body 1 and cylinder 3 processing get up simpler.And the utility model is in use if cylinder 3 wearing and tearing then only need to change cylinder 3 separately, need not as prior art to have improved the maintainalbility of diesel engine housing greatly together with replacing left box body 1.
Certainly the foregoing description only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the people who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection domain of the present utility model with this.All equivalent transformation or modifications of doing according to the spirit of the utility model main technical schemes all should be encompassed within the protection domain of the present utility model.
Claims (3)
