| description | The utility model discloses a DC motor noise reduction housing, which comprises a motor housing main body and a motor base, a middle cavity used for placing a rotor is arranged in the middle of the interior of the motor housing main body, and the left end of a rotating shaft is connected with fan blades; the left end of the rotating shaft is sequentially connected with a first sound insulation gasket and a first bearing in a sleeved mode, the right end of the rotating shaft is connected with a second sound insulation gasket and a second bearing in a sleeved mode, the channel is communicated with the middle cavity through a plurality of sets of communication holes, and a sound insulation plate is inserted into the channel. Noise generated by rotation of the rotor and the rotating shaft is reduced; after noise generated by rotation of the rotor and the rotating shaft is absorbed by the first sound insulation gasket and the second sound insulation gasket, part of the noise also enters the channel of the motor sh |
