it is described that to have flexible support be the elastic support with supporting role.
the further technical scheme of the present invention is: this noise reduction structure of motor also comprises motor cover, and the elastic support of described motor both sides is connected and fixed with described motor cover.
in order to better damping noise reduction, the bottom of motor described in the present invention is suspended in motor cover, by arranging other bolsters (as beam, spring etc.) between motor afterbody and motor cover, can certainly reach corresponding damping effect.The bottom of the preferred motor of the present invention is suspended on the scheme in motor cover, can avoid the contact between motor lower portion and motor cover like this, thus makes motor vibrations pass to motor cover, better can reduce noise, also can reduce production cost simultaneously.
further, all sides of described motor are provided with the electric machine support for fixed electrical machinery, and described elastic support is arranged between motor cover and electric machine support.
the concrete mounting structure of described elastic support is: the position of the relatively each elastic support in described motor cover upper edge is respectively equipped with locating slot, first beam is installed in described locating slot, there is in described first beam the mounting groove supplying the outer end of elastic support to be embedded, described motor cover is provided with and is attached thereto fixing outsides cover of electric machinery, the second beam is provided with between described outsides cover of electric machinery and motor cover, described second beam has the protuberance corresponding to mounting groove, the outer end of described elastic support is embedded in mounting groove, and be fixed by the protuberance of the second beam.Described electric machine support comprises at least one pair of support mutually fastened, and be all connected with elastic support between each support and motor cover, the inner end of described elastic support and respective holder are affixed merging and are connected by screw fixing.
described elastic support is elastic sheet metal.
advantage of the present invention is:
1. the present invention utilizes elastic support to connect electric machine support and motor cover, and this mode flexibly connected, while reduction vibrations, reduces noise.
2. the bottom of motor is preferably suspended in motor cover by the present invention, can avoid the contact between motor lower portion and motor cover like this, thus makes motor vibrations pass to motor cover, better can reduce noise, also can reduce production cost simultaneously.
3. the outer end of Elastic support of the present invention is embedded in the mounting groove of the first beam, and be fixedly clamped by the first beam and the second beam, this mounting means reduces the vibrations between elastic support and motor cover, outsides cover of electric machinery better, reduces noise better.

Detailed description of the invention
embodiment: as shown in Figures 1 to 7, a kind of noise reduction structure of motor being applied to dust catcher, comprise motor 1 and motor cover 3, described motor 1 week side is provided with the electric machine support 4 for fixed electrical machinery 1, and the elastic support 5 that described electric machine support 4 and motor cover 3 have supporting role by two or more is connected and fixed.In the present embodiment, described elastic support 5 is two, and the corresponding both sides being arranged on electric machine support 4, elastic support 5 is elastic sheet metal.
in order to better damping noise reduction, the bottom of motor 1 described in the present invention is suspended in motor cover 3, by arranging other bolsters (as beam, spring etc.) between motor 1 afterbody and motor cover 3, can certainly reach corresponding damping effect.The bottom of the preferred motor 1 of the present embodiment is suspended on the scheme in motor cover, can avoid the contact between motor 1 bottom and motor cover 3 like this, thus makes motor 1 vibrations pass to motor cover 3, better can reduce noise, also can reduce production cost simultaneously.
as shown in Figure 4, the concrete mounting structure of described elastic support 5 is: the position of the relatively each elastic support 5 in described motor cover 3 upper edge is respectively equipped with locating slot 31, first beam 6 is installed in described locating slot 31, there is in described first beam 6 mounting groove 61 supplying the outer end of elastic support 5 to be embedded, described motor cover 3 is provided with and is attached thereto fixing outsides cover of electric machinery 2, the second beam 7 is provided with between described outsides cover of electric machinery 2 and motor cover 3, described second beam 7 has the protuberance 71 corresponding to mounting groove 61, the outer end of described elastic support 5 is embedded in mounting groove 61, and be fixed by the protuberance 71 of the second beam 7.Described electric machine support 4 comprises at least one pair of support 41 mutually fastened, and be all connected with elastic support 5 between each support 41 and motor cover 3, the inner end of described elastic support 5 and respective holder 41 are affixed merga pass screw 8 and are connected and fixed.This mounting means reduces the vibrations between elastic support 5 and motor cover 3, outsides cover of electric machinery 2 better, reduces noise better.
