Abstract
The utility model discloses a cylinder cover hood, which is installed on a cylinder cover of an internal-combustion engine and comprises a cylinder cover hood body. A bearing cover adapted to a bearing seat on the cylinder cover is integrally molded on the bottom surface of the cylinder cover hood body, and when the cylinder cover hood body is installed on the cylinder cover, the bearing cover and the bearing seat on the cylinder cover together form a camshaft hole for fixedly installing a camshaft. Compared with the prior art, the cylinder cover hood of the utility model reduces the part number needing to be used for installing the camshaft of an internal-combustion engine air-distributing mechanism, simplifies the installation program and effectively improves the working reliability of an internal-combustion engine.
Description
Technical field
The utility model relates to a kind of valve mechanism cover, relates in particular to a kind of valve mechanism cover that is installed in the diesel engine.
Background technique
At present, the overhead type distribution device is applied in the various internal-combustion engines widely.In this distribution device, the top of cylinder head is provided with the bearing support that is used to install camshaft, fixedly mounts bearing cap on the bearing support again, and camshaft is fixedly installed between bearing support and the bearing cap.Because fixing needs the between bearing cap and the bearing support used component such as a large amount of bolts and latch, thereby make installation procedure quite complicated, this body structure of body is also compact inadequately, lubricated inconvenience, and functional reliability is not high.
The model utility content
The valve mechanism cover that provides a kind of compact structure, simple installation and functional reliability higher is provided the technical problems to be solved in the utility model.
For solving the problems of the technologies described above, the valve mechanism cover that the utility model provides has following structure:
A kind ofly be installed on the valve mechanism cover that cylinder of internal-combustion engine covers, comprise the valve mechanism cover body, on the bottom surface of described valve mechanism cover body one-body molded be provided with cylinder head on the adaptive bearing cap of bearing support, when described valve mechanism cover body was installed on the cylinder head, the bearing support on described bearing cap and the cylinder head was configured for fixedly mounting the camshaft hole of distribution device camshaft jointly.
Preferably, the top of described valve mechanism cover body has been wholely set the pre-filter block in Oil-gas Separation labyrinth, is used to install the labyrinth system that realizes the oil gas pre-flock.
Preferably, an end of described valve mechanism cover body has been wholely set the camshaft gear wheel chamber.
Preferably, the other end of relative camshaft gear wheel chamber is wholely set and is useful on the machine oil mouth that adds machine oil on the described valve mechanism cover body.
Preferably, an end of described valve mechanism cover body also is integrally formed with the sprocket wheel chamber that is used to hold sprocket wheel.
Compared with prior art, one-body molded on the utility model valve mechanism cover have bearing cap, thereby reduced to the number of spare parts of the required use of I. C engine distribution mechanism camshaft is installed, and simplified installation procedure, and improved the functional reliability of internal-combustion engine effectively.
Description of drawings
Fig. 1 is the top surface perspective of the utility model embodiment's valve mechanism cover;
Fig. 2 is the underside perspective view of the utility model embodiment's valve mechanism cover.
Employed mark is respectively in the above accompanying drawing:
1-valve mechanism cover body, 2-sprocket wheel chamber, the pre-filter block in 3-Oil-gas Separation labyrinth, 4-machine oil mouth, 5-exhaust side camshaft gear chamber, 6-intake-side camshaft gear chamber, 7-bearing cap.
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 depicted in figs. 1 and 2, this valve mechanism cover is the valve mechanism cover that is used on the four cylinder diesel engine with two top set formula distribution devices.The bottom surface of valve mechanism cover body 1 be provided with one-body moldedly with cylinder head on eight suitable bearing caps 7 of bearing support, when being installed on this valve mechanism cover body 1 on the cylinder head, bearing support on the cylinder head and the 7 common formations of the bearing cap on the valve mechanism cover install and fix the camshaft hole of camshaft.For obtaining high-precision camshaft hole, described cylinder head and valve mechanism cover body 1 can be closed the lid back camshaft hole is carried out fine finishing.After adopting such structure, when camshaft is installed, only camshaft need be placed on the bearing support on the cylinder head, again valve mechanism cover body 1 is closed and be placed on the cylinder head and fixing getting final product, numerous loaded down with trivial details steps such as the station location marker of required experience and Design Orientation mechanism have improved manufacturing efficiency greatly and have reduced cost of production when having saved the bearing cap installation camshaft that adopts separation separately.Simultaneously, adopt such structure also can improve the functional reliability of internal-combustion engine effectively.
Simultaneously, also be wholely set the sprocket wheel chamber 2 and the exhaust side camshaft gear chamber 5 and the intake-side camshaft gear chamber 6 that are used to hold camshaft gear wheel that holds sprocket wheel with suitable being used to of air cylinder head structure on this valve mechanism cover body 1.Side at valve mechanism cover body 1 also has been wholely set the pre-filter block 3 in Oil-gas Separation labyrinth, is used to install the labyrinth system, to realize the pre-flock of oil gas.And the also one-body molded machine oil mouth 4 that is provided with of an end in the relative camshaft gear wheel chamber of this valve mechanism cover body 1 is used for diesel engine is added machine oil.Such mechanism makes the whole level of integration height of diesel engine, and compact structure has solved the difficult problems such as loaded down with trivial details and sealing difficulty of installment work when these parts are provided with respectively, and has improved the functional reliability of internal-combustion engine greatly.
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.
