A kind of motor containing rubber absorbers of the utility model, it includes motor field frame, buffer layer, baffle, rubber Glue damper, stator, rotor, bearing, fan, rubber end plate, rubber bodies, rubber base plate, bolt.The shell of the motor Natural rubber buffer layer is installed, the motor field frame is internally provided with baffles, baffle and motor casing on inner wall Between there is radiator fan, the damping layer surface to there are rubber absorbers and stator, the stator of the motor to have accordingly successively Rotor matches, and the shaft of rotor is matched with corresponding bearing, and the surface of bearing and one end of damping device tightly overlap, and turns One end of sub- shaft sequentially passes through buffer layer and motor casing and extends to the outside of motor field frame, the rotor shaft other end Connect fan.

The rubber absorbers include rubber end plate, and the top of the rubber end plate is connect with bearing, under the end plate End is connected with rubber bodies, and the rubber bodies constitute the main body of rubber absorbers, and the bottom of the rubber bodies is connected with rubber base plate, There are two bolt hole, the rubber absorbers to be fixed on rubber shock-absorbing layer by two bolts for the rubber base plate.

Preferably, the quantity of the damper is four, each two damper is one group, and two groups of dampers are set respectively Set the upper and lower surface in rotor.

Preferably, the main body of the damper is natural rubber material, the top of four rubber absorbers end plates It is tightly pressed with the lower surface of two bearings respectively.

Preferably, there are two bolt holes respectively on the pedestal of four rubber absorbers, it will by two bolts Rubber absorbers are fixedly connected with rubber shock-absorbing layer.

The beneficial effects of the utility model are：

1, the utility model generates noise by the way that rubber absorbers and buffer layer is arranged when realizing reduction electric motor operation With the influence of vibrations.

2, by the rubber material of rubber absorbers, instead of original mechanical damper, in conjunction with buffer layer, structure letter It is single, it is easy for installation, keep damping effect more preferable, absorption of noise is better, extends service life of equipment, reduces equipment work when institute Influence of the noise of generation to people's lives.
