Abstract
The utility model provides an engine acoustic celotex board includes outer shell (2) and foam rubber layer (3), fasten in outer shell (2) inboard foam rubber layer (3), and corresponding engine gear engagement department ab intra outwards is equipped with the damping pit on the two -layer face. It is effectual that this engine acoustic celotex board has the sound insulation, and difficult because of engine vibration produces resonance, falls the advantage that the noise effect is obvious.
Description
Technical field
This utility model relates to a kind of baffle, is specifically related to a kind of baffle for electromotor.
Background technology
Electromotor, in running, inevitably occurring inner part vibration and gear drive to engage the mechanical vibration brought, thus causing noise, being therefore always up the emphasis of engine industry noise reduction work at the vibration and noise reducing at the sounding positions such as gear chamber.But tradition baffle soundproof effect is not good, and easily produce resonance because of engine luggine, it is impossible to reduce noise further.
Utility model content
This utility model is for the problems referred to above, it is provided that a kind of electromotor baffle, and it is good that this electromotor baffle has soundproof effect, and not easily produce resonance, noise-reducing effect clear advantage because of engine luggine.
Technical problem of the present utility model is solved by following technical scheme:
A kind of electromotor baffle, including baffle body, described baffle body includes outer shell and foaming rubber layer；Described foaming rubber layer is anchored on inside outer shell, 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 adopts is engineering plastics.
Further, the material that described outer shell adopts is clad steel.
Further, described damping pit depth is 4～5mm.
Further, described bipeltate layer thickness is 3～7mm.
Further, described outer shell edge is provided with the fixing groove of foaming rubber layer, for the cladding at foaming rubber layer edge.
Further, bonded by adhesive sticker between described outer shell and foaming rubber layer.
Further, described outer shell edge is additionally provided with some bolt mounting holes.
Further, described electromotor baffle is corresponding with engine gear case, offers output shaft outlet at engine output shaft correspondence position.
This utility model is compared with the prior art and provides the benefit that:
This utility model is combined in inside outer shell by using foaming rubber layer, collectively form a monoblock baffle, there is good absorption and intercept the effect of noise, and it is provided with damping pit from inside to outside in corresponding engine gear engagement place, preventing, effect in the baffle resonance with electromotor is fairly obvious, has been obviously improved the sound insulation and noise reduction performance of baffle.
