Abstract
The invention provides an acoustic panel of an engine. The acoustic panel comprises a shell layer (2) and a foam rubber layer (3). The foam rubber layer (3) is fastened on the inner side of the shell layer (2). Damping pits are formed in the portions, corresponding to the engaged positions of engine gears, of two layers of panel surfaces from inside to outside. The acoustic panel has the advantages of being good in sound insulation effect, not prone to generate resonance due to vibration of the engine and obvious in noise reduction effect.
Description
Technical field
The present invention relates to a kind of insulation board, be specifically related to a kind of insulation board for motor.
Background technique
Motor is in running, and inevitably the mechanical vibration brought are engaged in the vibration of generation inner piece and gear transmission, thus cause noise, are therefore the emphasis of engine industry noise reduction work at the vibration and noise reducing at the sounding positions such as gear chamber always.But traditional insulation board soundproof effect is not good, and easily produce resonance because of engine luggine, noise cannot be reduced further.
Summary of the invention
The present invention is directed to the problems referred to above, provide a kind of motor insulation board, it is good that this motor insulation board has soundproof effect, and not easily produce resonance because of engine luggine, the advantage of noise-reducing successful.
Technical problem of the present invention is solved by following technological scheme:
A kind of motor insulation board, comprise insulation board body, described insulation board body comprises outer shell layer and foaming rubber layer; Described foaming rubber layer is anchored on inside outer shell layer, and on two-ply face, corresponding engine gear engagement place is provided with damping pit from inside to outside.
Further, the material that described outer shell layer adopts is engineering plastics.
Further, the material that described outer shell layer adopts is Composite Steel.
Further, described damping pit depth is 4 ~ 5mm.
Further, described bipeltate layer thickness is 3 ~ 7mm.
Further, described outer shell layer edge is provided with foaming rubber layer fixed groove, coated for foaming rubber layer edge.
Further, bonded by adhesive sticker between described outer shell layer and foaming rubber layer.
Further, described outer shell layer edge is also provided with some bolt mounting holes.
Further, described motor insulation board is corresponding with engine gear case, offers output shaft outlet at engine output shaft corresponding position.
The beneficial effect that the present invention is compared with the prior art is:
The present invention is combined in inside outer shell layer by using foaming rubber layer, common formation one monoblock insulation board, there is the effect that good absorption intercepts noise, and be provided with damping pit from inside to outside in corresponding engine gear engagement place, in the resonance preventing insulation board and motor, effect is fairly obvious, significantly improves the sound insulation and noise reduction performance of insulation board.
