Abstract

The utility model discloses a balancing disk. A motor of a small-sized washing machine is changed to a two-end shaft extension motor. A shaft barrel is fixed with the lower end (free end) of a shaft of the motor. A locking nut is arranged on the lower portion of the shaft barrel. The balancing disk is connected on the periphery of the shaft barrel. Resonance produced by the motor and centrifugal force produced by the balancing disk of the shaft are little when the balancing disk is in a static condition or the motor revolves at a low speed. Generated centrifugal force of the balancing disk is at the maximum value when the motor shaft revolves quickly. Unbalanced force generated by clothes stacking in the washing machine is overcome, thus resonance produced by the unbalanced force caused by the clothes stacking is avoided.

Description

A kind of balancing frame

Technical field

The utility model 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, especially mini small washing machine is because fuselage is little, from heavy and light, therefore vibration is large in laundry processes, particularly when dehydration, vibration is larger under the effect of uneven centrifugal force, tend to occur the fuselage phenomenon of " walking ", when serious even can turn on one's side, greatly shortened the service life of washing machine, some producers are 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 large, this is a kind of oscillation damping method that forces in handling process, do not eliminate the source that produces resonance, so the effect of weakening is also undesirable.

The utility model content

In order to remedy the above-mentioned deficiency of washing machine, the utility model provides a kind of balancing frame, and this balancing frame adopts centrifugal process, the source of resonance is eliminated in the rotating shaft of washing machine, so that resonance is to the body propagation, to reach good effectiveness in vibration suppression.

The utility model solves the technical measures that its technical problem takes, motor with a kind of small washing machine, change the two ends output shaft motor into, the upper end of motor reel is fixed with the lower end of laundry spin dryer tube axle, the lower end of motor reel (free end) is beam barrel fixedly, screw is opened in the bottom of beam barrel, be screwed into locking nut in the screw, periphery at beam barrel connects balancing frame, balancing frame is made with the large metal material of density, balancing frame is made discoid, the wall thickness of the periphery of balancing frame, thinner near center wall, when inactive state or motor reel when low speed rotation, the centrifugal force of at this moment motor reel generation is little, when the rotating speed of motor reel increases gradually, centrifugal force also strengthens, when the motor reel fast rotational, at this moment the vibration of washing machine also increases, and the centrifugal force that the while balancing frame produces reaches maximum, piles up the out-of-balance force that is produced to overcome the washing machine undergarment, 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 beneficial effects of the utility model are, have not only subdued resonance, and the noise of having avoided vibration to produce, make the washing machine smooth running, have prolonged the life-span of washing machine, and are simple in structure.、

Description of drawings

Be described further the utility model 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. nut, 4. balancing frame, 5. periphery.

The specific embodiment

In Fig. 1, with a kind of small washing machine motor, change the two ends output shaft motor into, the upper end of motor reel is fixed with the lower end of laundry spin dryer tube axle, the lower end of motor reel 1 (free end) is beam barrel 2 fixedly, screw is opened in the bottom of beam barrel, is screwed into locking nut 3 in the screw, connects balancing frame 4 in the periphery of beam barrel, balancing frame is made with the large metal material of density, the weighing apparatus dish is made discoid, and the wall thickness of the periphery 5 of balancing frame is thinner near center wall.

Claims

1. balancing frame, it is characterized in that: with small washing machine motor, change the two ends output 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 is beam barrel fixedly, screw is opened in the bottom of beam barrel, be screwed into locking nut in the screw, connect balancing frame in the periphery of beam barrel, balancing frame is made collar plate shape, the wall thickness of the periphery of balancing frame is thin near center wall.
