Abstract
A sealing part of cylinder cover of diesel engine comprises a cylinder cover and a cover sealing part. The bottom surface is provided with a rubber sealing gasket with a T-shaped cross section. A bolt hole at the bottom of the cylinder cover therein is provided with a rubber component of a limiting skeleton. The T-shaped rubber sealing gasket is embedded in a seal groove of the cylinder cover, and the rubber component is partially embedded in the bolt hole. The plane formed by the limiting skeleton and the heterotypic rubber gasket component is tightly screwed by a bolt, the lower plane of the T-shaped rubber gasket is tightly contacted with the cylinder cover, the upper plane is contacted with the cylinder cover, and the bump of the rubber sealing gasket embedded in the seal groove of the cylinder cover is contacted with the top of the seal groove. The utility model has good sealing effect, prevents leakage of oil, has good shock insulation and noise-reducing effect, and can effectively reduce combustion noise and transmission of noise of air drain rocker arm.
Description
One, technical field
The utility model belongs to the diesel engine field, relates to a kind of diesel engine cylinder head cover sealed member.
Two, background technique
In the prior art, cylinder of diesel engine covers valve mechanism cover is housed, and between valve mechanism cover and the cylinder head sealing gasket is arranged, to prevent that machine oil from leaking outside, the intensity and the sealing of valve mechanism cover just considered in this design, and the function of its vibration isolation, noise reduction is considered seldom to make the global noise of diesel engine bigger than normal.
Three, summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of and can improve sealability, can reduce the diesel engine cylinder head cover sealed member of diesel engine noise again.
The utility model is achieved in that the rubber assembly that the diesel engine cylinder head cover sealed member comprises T type rubber gasket 1, valve mechanism cover 2, is made up of special-shaped rubber pad 3, spacing skeleton 4.It is characterized in that: T type rubber gasket 1 is embedded in the seal groove of valve mechanism cover 2, and special-shaped rubber pad 3 is partially submerged in the bolt hole.Tighten correlation plane by spacing skeleton 4 and special-shaped rubber pad 3 assembly parties by bolt, special-shaped rubber pad 3 contacts with valve mechanism cover 2, and T type rubber gasket 1 projection that embeds simultaneously in valve mechanism cover 2 seal grooves also contacts with the top of seal groove.
Special-shaped rubber pad 3, the assembly parts of spacing skeleton 4 for closely being made into one.
Adopt the utility model can reach following beneficial effect: the T type rubber gasket 1 between valve mechanism cover 2 and the cylinder cap has formed the seal space of a ring-type under the effect of valve mechanism cover 2 Bolt Tightening Force, both guaranteed that the machine oil in the valve mechanism cover 2 was non-leakage, prevented the transmission of the noise that valve and rocker part produce owing to moving again.Spacing skeleton 4 had both guaranteed that special-shaped rubber pad 3 contacted with the effective of valve mechanism cover 2, prevented the excessive damage of valve mechanism cover 2 Bolt Tightening Force T type rubber gasket 1 and rubber pad 3 again.Owing between each Metal Contact face rubber pad is arranged, vibration and noise have been reduced effectively simultaneously.
Four, description of drawings
Fig. 1 is the structural representation of the utility model diesel engine cylinder head cover sealed member.
Five, embodiment
Mode of execution of the present utility model is referring to shown in the accompanying drawing 1.
The diesel engine cylinder head cover parts comprise installs the rubber assembly that T type rubber gasket 1, special-shaped rubber pad rubber pad 3 and spacing skeleton 4 are formed on the valve mechanism cover 2.Under the effect of Bolt Tightening Force, the lower plane of T type rubber pad 1 closely contacts with cylinder head, and last plane contacts with valve mechanism cover 2, and the projection that embeds simultaneously in valve mechanism cover 2 seal grooves also contacts with the top of seal groove.Formed space like this, not only prevented the seepage of machine oil and fuel-air mixture effectively, also reduced simultaneously the transmission of the vibration noise that produces owing to rocking arm and valve motion with double seal.Tighten correlation plane by bolt, so both guaranteed that special-shaped rubber pad 3 was not crushed by bolt, special-shaped rubber pad 3 is pressed on the valve mechanism cover 2 by spacing skeleton 4 and special-shaped rubber pad 3 assembly parties.By the length of the spacing skeleton 4 of rational design, can guarantee that T type rubber pad 1 and special-shaped rubber pad 3 can both reach best sealing state when bolt is tightened.Simultaneously because not directly contact between each metal covering has reduced the generation of vibration noise effectively.
