Abstract
The utility model discloses a split type cylinder cover hood, which belongs to the technical field of parts of an internal-combustion engine. The split type cylinder cover hood comprises a cylinder cover hood body, the cylinder cover hood body comprises an upper cover and a lower cover which are connected with each other by fasteners, thus both the upper cover and the lower cover are provided with a plurality of installation pars corresponding to one another, and the fasteners are connected with the installation parts. The split type cylinder cover hood not only can meet the strength requirement, but also can be removed and installed conveniently, and is widely applied to the manufacturing and use of the internal-combustion engines.
Description
Technical field
The utility model relates to the gas engine part technical field, relates in particular to a kind of split type valve mechanism cover.
Background technique
Valve mechanism cover is one of common component of diesel engine, and it mainly acts on is to prevent that the machine oil in the valve mechanism cover from leaking outside, and in the design process of valve mechanism cover, should pay special attention to the intensity and the sealability of valve mechanism cover.At present, valve mechanism cover adopts integral casting forming usually in order to reach enough intensity, and this just safeguards to dismounting and makes troubles.
The model utility content
Technical problem to be solved in the utility model is: a kind of split type valve mechanism cover is provided, can either satisfies requirement of strength, again dismounting easily.
For solving the problems of the technologies described above, the technical solution of the utility model is: split type valve mechanism cover, comprise the valve mechanism cover body, described valve mechanism cover body comprises loam cake and the lower cover that links together by fastening piece, described loam cake and lower cover are equipped with the assembly department of some mutual correspondences, and described fastening piece connects described assembly department.
As a kind of improvement, be provided with sealing joint strip between described loam cake and the lower cover.
As a kind of improvement, the inwall of described loam cake is provided with the stiffening rib that is used to increase described loam cake intensity.
After having adopted technique scheme, the beneficial effects of the utility model are: because valve mechanism cover comprises loam cake and lower cover, during making, can adopt the aluminium alloy casting moulding respectively, produce in batches, guarantee the needed requirement of strength of valve mechanism cover, the processing back links together by fastening piece, further improved the intensity of valve mechanism cover, and fastening piece can dismantle easily, be convenient to maintaining.
Owing to be provided with sealing joint strip between loam cake and the lower cover, prevented the lubricating oil leakage in the cylinder head effectively, further improved sealing effect.
Because the inwall of loam cake is provided with the stiffening rib that is used to increase described loam cake intensity, has further improved the intensity of valve mechanism cover, has prolonged the working life of valve mechanism cover.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model embodiment's a structural representation;
Fig. 2 is the right elevation of Fig. 1;
Among the figure: 1, loam cake, 11, stiffening rib, 2, lower cover, 3, sealing joint strip, 4, fastening screw trip bolt, 5, assembly department.
Embodiment
As depicted in figs. 1 and 2, a kind of split type valve mechanism cover, mainly comprise the valve mechanism cover body, described valve mechanism cover body comprises loam cake 1 and the lower cover 2 that links together by fastening piece, the inwall of described loam cake 1 is provided with the stiffening rib 11 that is used to increase described loam cake 1 intensity, and the shape of stiffening rib 11 and trend are not limited to, and described loam cake 1 and lower cover 2 are equipped with the assembly department 5 of some mutual correspondences, described fastening piece connects described assembly department 5, and described fastening piece is preferably fastening screw trip bolt 4.
According to conventional design, the shape of the junction surface of loam cake 1 and lower cover 2 is consistent, and be equipped with the corresponding assembly department 5 in position, on the loam cake assembly department, offer through hole, on the lower cover assembly department, be provided with tapped hole, loam cake 1 and lower cover 2 link together by fastening screw trip bolt 4, in order to guarantee sealing effect, are provided with sealing joint strip 3 between described loam cake 1 and the lower cover 2.
The utility model is not limited to above-mentioned concrete mode of execution, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within the protection domain of the present utility model.
