Abstract
The utility model discloses a vibration and noise reducing device of an engine cylinder cover hood, which is arranged at the position of the bottom edge of the cylinder cover hood, corresponding to a mounting surface of a cylinder cover. The vibration and noise reducing device comprises a groove body and a rubber sealing pad arranged in the groove body; the size of the groove body is matched with that of the rubber sealing pad; and two sides of the groove body are provided with groove walls which are inner side groove walls and outer side groove walls. The groove body is a rectangular groove or a trapezoidal groove. The width of the rectangular groove is larger than 3.5mm, and the depth of the groove body is 4mm to 7mm. The thicknesses of the inner side groove walls and the outer side groove walls are larger than or equal to 2.5mm. Each internal corner and each external corner of the groove body are respectively processed into chamfers with arc surfaces, and the radiuses of the chamfers with the arc surfaces are 0.5mm to 1mm. The vibration and noise reducing device can arrange the rubber sealing pad in the groove body and has good functions of reducing vibration and noise.
Description
Technical field
The utility model relates to a kind of engine air cylinder cap, particularly a kind of vibration and noise reducing device of engine air cylinder cap.
Background technique
The purpose of valve mechanism cover vibration and noise reducing is to reduce the valve mechanism cover vibration that motor brings by the vibration of motor and reduce the noise that is brought by vibration in running, improves the reliability of valve mechanism cover work.The major defect of valve mechanism cover vibration and noise reducing of the prior art is that valve mechanism cover is with sealing by general liner plate between the cylinder head, the vibration of motor is big during work, cause the valve mechanism cover vibration big, noise is big, reduces the reliability and the working life of valve mechanism cover.Because vibration, problems such as crackle and sealing surface leakage of oil appear in valve mechanism cover when causing the motor operation easily, thereby influence the safe in utilization of motor.
The model utility content
The utility model is in order to overcome defective in the above-mentioned prior art, by one of processing on the sealing surface of cast aluminium valve mechanism cover the seal groove of vibration isolation rubber sealing gasket is installed, by valve mechanism cover the squeezing action of sealing gasket is reduced the vibration of valve mechanism cover to reach the effect of noise reduction during engine operation.
Engine air cylinder cap vibration and noise reducing device of the present utility model, be located at the corresponding position of valve mechanism cover bottom margin and cylinder head attachment face, comprise cell body and be installed in the interior rubber gasket of cell body, cell body size and rubber gasket size are suitable, cell wall is established in the cell body both sides, and cell wall is divided into inboard cell wall and outside cell wall.
Preferably, cell body is a rectangle groove, and the width of rectangle groove is more than or equal to 3.5mm, and the cell body degree of depth is 4mm to 7mm.
Preferably, cell wall thickness in medial and lateral is more than or equal to 2.5mm.
Preferably, the burr limit of cell body (being each negative and positive angle) all is processed into the arc surface chamfering, and the arc surface chamfer radius is 0.5mm to 1mm.
Preferably, cell body can also be dovetail groove.
Compared with prior art, the utlity model has following beneficial effect:
1, the engine air cylinder cap vibration and noise reducing device can be installed rubber gasket in cell body, has the effect of favorable damping noise reduction;
2, by valve mechanism cover compressing rubber sealing gasket, better than the sealing effect of conventional pads;
3, can effectively improve the working life of valve mechanism cover.
Description of drawings
Fig. 1 is the utility model valve mechanism cover worm's eye view;
Fig. 2 is that the A-A of Fig. 1 is to sectional view;
Fig. 3 is the B portion enlarged view (being cell body and cell wall schematic representation in the utility model valve mechanism cover vibration and noise reducing device) of Fig. 2;
Fig. 4 is the utility model valve mechanism cover stereogram.
Mark the following drawings mark thereon in conjunction with the accompanying drawings:
The 1-cell body, the inboard cell wall of 2-, 3-outside cell wall, 4-arc surface chamfering.
Embodiment
Below in conjunction with accompanying drawing, an 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 shown in Figure 1 and Figure 2, engine air cylinder cap vibration and noise reducing device of the present utility model, be located at the corresponding position of valve mechanism cover bottom margin and cylinder head attachment face, comprise cell body 1 and the rubber gasket (not shown) that is installed in the cell body 1, cell body 1 size and rubber gasket size are suitable, cell wall is established in the cell body both sides, and cell wall is divided into inboard cell wall 2 and outside cell wall 3.
Engine air cylinder cap vibration and noise reducing device of the present utility model can be installed rubber gasket in cell body, have the effect of favorable damping noise reduction; By valve mechanism cover compressing rubber sealing gasket, better than the sealing effect of conventional pads; This vibration and noise reducing device can effectively improve the working life of valve mechanism cover.
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.
