Description
Technical field
The utility model relates to a kind of motor, especially a kind of motor with cup rotor that is used on the massager.
Background technology
Motor with cup rotor is widely used in various electrical equipment at present, traditional as shown in Figure 1 motor with cup rotor, the two ends band of motor shaft 2 eccentric block 3 and the eccentric block 13 of 250g, the middle part of motor shaft is provided with rotor 1, on motor shaft, be provided with the 3rd plastic sleeve 5, the 4th plastic sleeve 15, the 3rd nylon washer 6, the 4th nylon washer 16, the 4th oiliness bearing 7 of the 3rd oiliness bearing 14 of band cast aluminium support and band cast aluminium support, be provided with the 3rd plastic sleeve 5 between rotor 1 and the eccentric block 3 successively, the oiliness bearing 14 of the 3rd nylon washer 6 and band cast aluminium support, rotor 1 is adjacent with the 3rd plastic sleeve 5, be provided with the 4th plastic sleeve 15 between rotor 1 and the eccentric block 13 successively, the oiliness bearing 7 of the 4th nylon washer 16 and band cast aluminium support, rotor 1 is adjacent with the 4th plastic sleeve 15. because load is heavy, motor shaft 2 produces axial motion, and noise and strike note are bigger; Simultaneously because the running of band eccentric load, motor shaft 2 and 7 frictions of the 4th oiliness bearing are serious, motor shaft 2 and 14 frictions of the 3rd oiliness bearing are serious, nylon washer 6 and 14 frictions of the 3rd oiliness bearing are serious, the 3rd nylon washer 6 and 7 frictions of the 4th oiliness bearing are serious, lubricated not enough, under indivedual opposite extreme situations motor is blocked does not change.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of reduction noise, and long motor with cup rotor of life-span.
The realization the technical solution of the utility model is as follows:
A kind of motor with cup rotor of noise reduction sound, comprise motor shaft, and be arranged on rotor on the motor shaft, also comprise the first string circle and the second string circle that are arranged on the motor shaft, also be provided with first nylon washer on the described motor shaft, second nylon washer, first plastic sleeve, second plastic sleeve, described first nylon washer and second nylon washer place an end of rotor, described first plastic sleeve and second plastic sleeve place the other end of rotor, described second plastic sleeve is adjacent with rotor, described first plastic sleeve is adjacent with rotor, the described first string circle is between first nylon washer and first plastic sleeve, and the described second string circle is between second nylon washer and second plastic sleeve.
The motor with cup rotor of a kind of noise reduction sound described in the utility model, wherein, the described first string circle and the second string circle are the string circle of oil-containing.
A kind of beneficial effect described in the utility model described in the utility model is: described motor the tip of the axis is a round end, and a side friction is reduced in the both sides friction that motor rotates, and has obviously reduced the noise of motor, has improved the useful life of motor with cup rotor axle.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the front view of motor with cup rotor in the background technology;
Fig. 2 is the motor with cup rotor front view of a kind of noise reduction sound of the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
A kind of motor with cup rotor of noise reduction sound, comprise motor shaft 9, and be arranged on rotor 11 on the motor shaft, comprise that also the first string circle 8 that is arranged on the motor shaft 9 and the second string circle, 4, the first string circles 8 and the second string circle 4 are the string circle of oil-containing.Also be provided with first nylon washer 10 on the motor shaft 9, second nylon washer 17, first plastic sleeve 18, second plastic sleeve 12, first nylon washer 10 and second nylon washer 17 place an end of rotor 11, first plastic sleeve 18 and second plastic sleeve 12 place the other end of rotor 11, second plastic sleeve 12 is adjacent with rotor 11, first plastic sleeve 18 is adjacent with rotor 11, the first string circle 8 is between first nylon washer 10 and first plastic sleeve 18, the second string circle 4 is between second nylon washer 17 and second plastic sleeve 12, and the first string circle 8 and the second string circle 4 are the string circle of oil-containing.
Motor shaft 9 produces reciprocal axial motion, when motor shaft 9 axial motions generation impulsive force is transmitted along the left side of arriving rotor 11, because the swollen phenomenon that rises takes place in the first string circle 8 when having absorbed lubricating oil, the motor shaft 9 compressions first string circle 8 is extruded the lubricating oil that the first string circle 8 is absorbed.The friction of the lubrication motor axle 9 and first nylon washer 10, the lubrication motor axle 9 and the first rubber axle sleeve 18 reduced the friction noise of motor, and string circle 4 begin to absorb the oil of emitting just as sponge.
When motor shaft 9 axial motions generation impulsive force is transmitted along the right side of arriving rotor 11, because the swollen phenomenon that rises takes place in the second string circle 4 when having absorbed lubricating oil, motor shaft 9 can compress the second string circle 4, extrude the lubricating oil that the second string circle 4 is absorbed, the friction of the lubrication motor axle 9 and second nylon washer 17, the lubrication motor axle 9 and the second rubber axle sleeve 12 reduced the friction noise of motor, and string circle 8 begin to absorb the oil of emitting just as sponge.String circle 4 and string circle 8 are drained the oil by the suction that goes round and begins again like this, have significantly reduced the noise of motor, and in the life-span of also having improved motor simultaneously, stability also obviously strengthens during motor rotation.
More than show, described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof
