CN102720039A - Balance disc - Google Patents

Abstract

The invention discloses a balance disc. A motor of a small-sized washing machine is changed into a motor of which the two ends are pierced by a shaft; the lower end (free end) of the motor shaft is fixedly provided with a shaft barrel; a locking nut is arranged on the lower part of the shaft barrel; and the periphery of the shaft barrel is connected with the balance disc. When the balance disc is static or the motor shaft is rotated at a low speed, low resonance can be generated by the motor shaft, and low centrifugal force is generated; and when the motor shaft is rotated at a high speed, the centrifugal force generated by the balance disc can reach the maximum value, so that unbalanced force generated by accumulating clothes in the washing machine can be eliminated, and resonance can be prevented from being generated by the unbalanced force caused by accumulating the clothes.

Description

A kind of balancing frame

Technical field

The present invention relates to a kind of washing machine, specifically a kind of device of subduing vibration of washing machine.

 

Background technology

Vibration is the greatest drawback of laundry, and especially mini small washing machine is because fuselage is little, and from heavy and light, therefore vibration is big in laundry processes; Particularly in when dehydration, under uneven action of centrifugal force vibration bigger, tend to occur the fuselage phenomenon of " walking "; When serious even can turn on one's side, shortened the service life of washing machine greatly, the producer that has is in order to reduce the vibration of washing machine; The cement block ballast is adopted in bottom at washing machine, increases the deadweight of washing machine, to reach effectiveness in vibration suppression; But because from great, expense is also big in handling process; This is a kind of oscillation damping method that forces, and do not eliminate the source that produces resonance, so the effect of weakening is also undesirable.

Summary of the invention

In order to remedy the above-mentioned deficiency of washing machine, the present invention provides a kind of balancing frame, and this balancing frame adopts centrifugal process, and the source of resonance is eliminated in the rotating shaft of washing machine, makes resonance not propagate to body, to reach the favorable damping effect.

It is with a kind of motor of small washing machine, to change two ends shaft motor into that the present invention solves the technical measures that its technical problem takes; The upper end of motor reel is fixed with the lower end of laundry spin dryer tube axle, and the lower end of motor reel (free end) be beam barrel fixedly, and screw is opened in the bottom of beam barrel; Be screwed into the locking screw nurse in the screw, connect balancing frame in the periphery of beam barrel, balancing frame is processed with the big material of density; Balancing frame is processed discoid, and the wall thickness of the periphery of balancing frame is thin more near center wall; When inactive state or motor reel when low speed rotation, at this moment the centrifugal force that produces of motor reel is little, when the rotating speed of motor reel increases gradually; Centrifugal force also strengthens, and when the motor reel fast rotational, the vibration of washing machine at this moment also increases; The centrifugal force that balancing frame produced simultaneously reaches maximum, to overcome the out-of-balance force that the clothing accumulation is produced in the washing machine, the resonance that the out-of-balance force of avoiding the clothing accumulation to cause produces; The source of resonant excitation is subdued in rotating shaft, resonance is passed to staving, thereby reach the purpose of vibration damping.

The invention has the beneficial effects as follows, not only subdued resonance, and the noise of having avoided vibration to be produced, make the washing machine running steadily, prolonged the life-span of washing machine, simple in structure.

Description of drawings

Be described further the present invention is bright below in conjunction with accompanying drawing.

Accompanying drawing is a kind of structural representation of balancing frame;

Among the figure, 1. motor reel, 2. beam barrel, 3. spiral shell nurse, 4. balancing frame, 5. periphery.

The specific embodiment

In Fig. 1, with a kind of small washing machine motor, change two ends shaft motor into; The upper end of motor reel is fixed with the lower end of laundry spin dryer tube axle, and the lower end of motor reel 1 (free end) be beam barrel 2 fixedly, and screw is opened in the bottom of beam barrel; Be screwed into locking screw nurse 3 in the screw, connect balancing frame 4 in the periphery of beam barrel, balancing frame is processed with the big material of density; The weighing apparatus dish is processed discoid, and the wall thickness of the periphery 5 of balancing frame is thin more near center wall.

Claims (2)

1. balancing frame is characterized in that: with small washing machine motor, change two ends shaft motor into; The upper end of motor reel is fixed with the lower end of laundry spin dryer tube axle, and the lower end of motor reel (free end) be beam barrel fixedly, and screw is opened in the bottom of beam barrel; Be screwed into the locking screw nurse in the screw, connect balancing frame in the periphery of beam barrel, dish is processed collar plate shape; The wall thickness of the periphery of balancing frame is thin near center wall.

2. a kind of balancing frame according to claim 1 is characterized in that: said balancing frame is processed with the big material of density.
