Abstract
The utility model relates to a layered noise reduction structure for a gear chamber, which comprises a gear chamber shell and is characterized in that a layered sound insulating structure consisting of a sound insulating plate and a sound insulating cushion is arranged on the outer surface of the gear chamber shell. The layered noise reduction structure for the gear chamber has the advantages that with the addition of the layered noise reduction structure on the outer surface of the gear chamber shell, the noise reduction effect of the gear chamber can be effectively improved; and compared with the noise reduction method in the prior art, the layered noise reduction structure has the advantages that the structure is simple, the processing and the manufacture are easy, and the production cost is low.
Description
Technical field
The utility model belongs to technical field of engines, particularly relates to a kind of gear chamber stratiform denoising structure.
Background technique
At present, engine noise is one of a measured engine quality very important parameters.In the known technology; The noise that reduces engine gear case generally is to realize through methods such as the machining accuracy that improves gear, the baroque gear chamber housings of making; So just increased the production and processing cost of motor greatly, and baroque gear chamber housing is difficult for making.
Summary of the invention
This use novel for solve the technical problem that exists in the known technology provide a kind of simple in structure, processing easily, excellent noise reduction effect, can reduce the stratiform denoising structure of engine gear case of the cost of production of motor.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of gear chamber stratiform denoising structure; Comprise the gear chamber housing, it is characterized in that: on the outer surface of said gear chamber housing, be provided with the stratiform acoustic construction of forming by insulation board and sound insulating pad.
The utility model can also adopt following technological scheme:
Layered acoustic construction is made up of two-layer insulation board and one deck sound insulating pad, and said sound insulating pad is arranged between the two-layer insulation board.
Layered acoustic construction is fixed on the outer surface of gear chamber housing through fastening piece.
Advantage and the good effect that the utlity model has are: the utility model is through adding the stratiform denoising structure on the outer surface of gear chamber housing; Can effectively improve the noise reduction of gear chamber; And compare noise-reduction method of the prior art, also have advantage simple in structure, that processing and fabricating is easy and cost of production is low.
Description of drawings
Fig. 1 is the structural representation of model utility.
Among the figure: 1, gear chamber housing; 2, insulation board; 3, sound insulating pad.
Embodiment
For further understanding the novel summary of the invention of this use, characteristics and effect, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1, a kind of gear chamber stratiform denoising structure comprises gear chamber housing 1, through fastening piece the stratiform denoising structure is installed on the outer surface of gear chamber housing 1.The bedded formation structure is made up of with one deck sound insulating pad 3 two-layer insulation board 2, and wherein sound insulating pad 3 is between two-layer insulation board 2.Insulation board 2 is plate bodys that soundproof material is processed, and there is bigger weight in closely knit imporosity of soundproof material or slit, and soundproof material can weaken transmission acoustic energy, the propagation of block sound; Sound insulating pad 3 is processed by sound absorbing material, and sound absorbing material is porous, loose and ventilative material, can absorb noise.Not only soundproof effect is good for the stratiform acoustic construction that above-mentioned insulation board and sound insulating pad are formed, and processing and fabricating is easy, and cost is low.
Claims (3)
