Abstract
The utility model relates to a fitment of diesel engine, in particular to a cylinder head cover for diesel engine. The cylinder head cover for diesel engine is made of modified plastic, comprising a cover body. The cover body is provided with a binding bolt hole and a built-in oil passage hole which is communicated with an oil pressure gauge hole. The inner wall of the cover body and the outer wall of the cover body are respectively provided with an inner strengthened rib and an outer strengthened rib. Because the utility model adopts modified plastic as materials, the utility model provides a modified plastic cylinder head cover with advantages of low cost, simple structure, light weight, low working noise, and effective prevention from oil leakage.
Description
Affiliated technical field
The utility model relates to diesel engine part, especially a kind of diesel engine cylinder head cover.
Background technique
Traditional cylinder of diesel engine housing generally adopts cast iron or cast aluminium manufacturing, the cost height, weight is big, noise is big, shape is difficult to guarantee, the oil pipe that is attached thereto simultaneously generally adopts externally connected type, occurs rocking because of oil pipe the phenomenon of leakage of oil in working process of diesel engine easily.
Summary of the invention
In order to overcome all drawbacks of bringing because of the diesel engine cylinder head cover that adopts cast iron or cast aluminium manufacturing because of above-mentioned, now provide a kind of diesel engine modified plastics valve mechanism cover.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of diesel engine modified plastics valve mechanism cover, has cover body, cover body is provided with bolt fastening hole, stiffening rib and outer stiffening rib in the cover body inside and outside wall is respectively arranged with, be provided with built-in oil channel hole and oil pressure gauge hole in the cover body wall, the oil pressure gauge hole is communicated with built-in oil channel hole.
A kind of diesel engine modified plastics valve mechanism cover of the present utility model has the following advantages: 1. be material by adopting with plastics, make the valve mechanism cover manufacture cost reduce more than 30%; 2. adopt the injection mould extrusion modling, surface finishment improves more than 10 times, weight saving 50%; 3. plastics belong to mute sound material, thereby have reduced valve mechanism cover radiated noise and even total noise of centrifuge; 4. the utility model adopts the modified plastics of special processing, has good ageing resistance and creep resistance, really realizes high strength, high-performance and high low temperature adaptability; And the plastic gas cylinder head cover can make shades of colour, can beautify the diesel engine outward appearance; 4. adopt in oil pipe and the valve mechanism cover to connect, reduced coupling, effectively avoided the external situation that occurs leakage of oil easily of oil pipe.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a single cylinder engine cylinder head cover structural representation of the present utility model.
Fig. 2 is the right elevation of Fig. 1.
Fig. 3 is a multi-cylinder engine cylinder head cover structural representation of the present utility model.
Fig. 4 is the left view of Fig. 3.
Among the figure: 1. cover body, 2. built-in oil channel hole, 3. bolt fastening hole, 4. oil pressure gauge hole, 5. in stiffening rib, 6. outer stiffening rib.
Embodiment
As Fig. 1, Fig. 2, Fig. 3, diesel engine modified plastics valve mechanism cover of the present utility model shown in Figure 4, with special modified plastics, these plastics have good ageing resistance and creep resistance, adopt the injection mould extrusion modling to make, its cover body 1 profile keeps consistent with original valve mechanism cover substantially, be provided with bolt fastening hole 3 on cover body top, cover body 1 is provided with built-in oil channel hole 2 and substitutes original oil channel hole external interface, saved external oil pipe coupling, simplified the structure of valve mechanism cover, also being provided with oil pressure gauge hole 4 on cover body 1 is connected with built-in oil channel hole 2, in cover body 1 inside and outside wall is provided with stiffening rib 5 and outside stiffening rib 6, body valve mechanism cover structure is more firm.
When mounted, oil pipe is directly stretched into built-in oil channel hole 2 connect, it is more firm that oil pipe is connected with the valve mechanism cover joint, and it is external to have overcome original employing oil pipe and valve mechanism cover, produces when working because of diesel engine and rocks the defective that makes the easy leakage of oil in joint.
For can with original fine cooperation of externally connected type oil pipe, the utility model can be the built-in oil channel hole of the valve mechanism cover 2 ingress setting tubing interface consistent with original external of material adopting modified plastics also, enables to substitute well original iron or aluminum valve mechanism cover.
The utility model is a material by adopting with the modified plastics, provides that a kind of cost of production is low, simple in structure, in light weight, operational noise is low, can effectively prevent the modified plastics valve mechanism cover of leakage of oil.
