Abstract

The utility model relates to a valve-chamber hood of a diesel engine, which comprises a valve-chamber hood body, and is characterized in that one side edge of the valve-chamber hood body is provided with a semi-circular inner concave, and the other side edge is provided with a semi-circular projection that is integrated with the semi-circular inner concave into a whole body, so as to form an asymmetrical structure at the two sides of the valve-chamber hood body. The valve-chamber hood has the advantages that the asymmetrical structure not only favors the assembling that brings about the convenience to the mounting operation and prevents the inversion and reversing mounting during the mounting process, but also shortens the assembling time, thereby greatly improving the working efficiency. In addition, the projection structure at the right side comprises a cylinder-cover bolt; the covering area of the valve-chamber hood is enlarged by increasing the reinforced structure, thus can effectively reduce the noise of the engine.

Description

The diesel engine cyclinder head cover
Technical field
The utility model belongs to diesel engine manufacturing technology field, particularly relates to the diesel engine cyclinder head cover that a kind of left and right sides is asymmetric, be convenient to install and reduce noise.
Background technique
The both sides of the cyclinder head cover of diesel engine all are shaped on concave inward structure in the known technology, and cyclinder head cover must guarantee the accuracy of its assembling in assembly process as the important spare part in the diesel engine.At present, owing in the cyclinder head cover installation process, rely on the experience of installation personnel itself and custom that it is installed fully, and easily by about load in mixture, cause taking place often setup error, thus be difficult to guarantee the accuracy of assembling, and influenced working efficiency greatly.In addition, cyclinder head cover is also having irreplaceable effect aspect the control of motor overall noise, be one of critical component that is related to engine noise, traditional noise reduction mode mostly is increases stiffening rib on cyclinder head cover, but reducing the noise result aspect does not obtain qualitative leap as yet.
Summary of the invention
The utility model provides the diesel engine cyclinder head cover that a kind of left and right sides is asymmetric, be convenient to install and reduce noise for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is: the diesel engine cyclinder head cover, comprise a valve cage cover body, it is characterized in that: a side of valve cage cover body is shaped on a semicircle indent, another side is shaped on a semicircle outer lug that is connected as a single entity with it, to form valve cage cover body left and right sides dissymmetrical structure.
The utility model can also adopt following technological scheme:
Described semi-cylindrical hill outside at valve cage cover body opposite side also is provided with the stiffening rib that is connected as a single entity with it.
Advantage and the good effect that the utlity model has are: because the utility model cyclinder head cover left side is designed to indent, the right side is designed to convex to form the dissymmetrical structure of cover body, so not only help assembling, provide convenience to fitting operation, avoid in installation process occurring reversed left to right, dress is anti-and dress falls, and shortened the installation time of assembling this link, improved work efficiency greatly.The protruding structure of this external right side has comprised the cylinder bolt of this side, by increasing the area coverage that reinforcing rib structure has strengthened cyclinder head cover, can reduce the noise of motor effectively.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the plan view of Fig. 1.
Among the figure: 1, valve cage cover body; 2, semicircle indent; 3, semi-cylindrical hill; 4, stiffening rib.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, the diesel engine cyclinder head cover, comprise a valve cage cover body 1, the limit, left side of valve cage cover body is shaped on a semicircle indent 2, its right edge is shaped on a semi-cylindrical hill that is connected as a single entity with it 3, the cylinder bolt on right side is comprised wherein, to form valve cage cover body left and right sides dissymmetrical structure.In installation process, help operator's identification like this, avoid that cyclinder head cover is reversed left to right, adorn instead or the direction dress is fallen.Outside at the semi-cylindrical hill 3 on valve cage cover body right side also is provided with the stiffening rib 4 that is connected as a single entity with it, by increasing the area coverage of cyclinder head cover, can reduce the noise of motor effectively.

Claims (2)

1. diesel engine cyclinder head cover, comprise a valve cage cover body, it is characterized in that: a side of valve cage cover body is shaped on a semicircle indent, and another side is shaped on a semi-cylindrical hill that is connected as a single entity with it, to form valve cage cover body left and right sides dissymmetrical structure.
2. diesel engine cyclinder head cover according to claim 1 is characterized in that: described semi-cylindrical hill outside at valve cage cover body opposite side also is provided with the stiffening rib that is connected as a single entity with it.
