Abstract

PROBLEM TO BE SOLVED: To provide a device to keep a well rotation balance by a balance adjusting cylinder on the outside of a rotary body even when an unbalance occurs to the rotary body. SOLUTION: A balance adjusting cylinder 2 provided with an inner cylinder 3 the inside of which is partitioned into a plurality of equal sections by partition plates 5 is mounted on the outside of a rotary body 1. An adjusting ring 4 having a portion between the inner cylinder 3 and the ring supported by a rubber liner 8 is situated outside the inner cylinder 3. A spherical ring 6 and a check valve 10 are mounted on the inner cylinder 3 and the adjusting ring 4.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic rotational balance adjusting device for automatically adjusting the amount of liquid obtained by dividing the unbalance of a rotating body along a cylinder on the outside of the rotating body. .

[0002]

2. Description of the Related Art Conventionally, there is no automatic rotation balance adjusting device for automatically adjusting the amount of liquid divided along a cylinder outside a rotating body so as to balance the rotation.

[0003]

SUMMARY OF THE INVENTION According to the present invention, even if the rotating body has an imbalance, the rotating balance can be obtained by automatically adjusting the liquid amount divided along the cylinder outside the rotating body. It is intended to be.

[0004]

In order to achieve the above object, the present invention provides an automatic rotational balance adjusting apparatus according to the present invention, wherein a rotating body is provided with an inner cylinder having an inner cylinder divided into several equal parts by a partition plate. Attach the adjustment cylinder, insert the adjustment ring supported by the rubber liner between the middle cylinder and the outside of the middle cylinder, and when the rotating body swings due to imbalance, turn the adjustment ring with the rubber liner to the one with the heavier center of gravity. When the sphere is compressed and eccentric, the spherical valve with the heavier center of gravity opens and the liquid inside the middle cylinder, which was partitioned by the partition plate, is discharged to the outside to balance the rotation. The discharged outside liquid is returned to the inside by a check valve.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on examples with reference to the drawings. In FIG. 1, a balance adjusting cylinder 2 having a middle cylinder 3 whose inside is equally divided by a partition plate 5 is attached to the outside of the rotating body 1, and a rubber liner is provided between the middle cylinder 3 and the outside of the middle cylinder 3. Adjusting ring 4 supported by 8
And the spherical valve 6, the valve support rubber 7, and the check valve 10 are attached to the middle cylinder 3 and the adjustment ring 4 while being partitioned by the partition plate 5. The adjustment ring 4 restricts the range of movement by the stopper 11, and the spherical valve 6 and the valve support rubber 7 make holes in the adjustment ring 4 and can be attached and detached with the lid 9. FIG. 2 is a sectional view showing the arrangement of the partition plate 5, the spherical valve 6, and the like. In addition, the amount of the liquid 12 to be put into the middle cylinder 3 is set so that the amount held at the time of rotation stop and the amount held within the height of the partition plate 5 at the time of rotation are the same.

[0006]

As described above, the imbalance during rotation of a large washing / dehydrating machine or the like is eliminated, so that high-speed rotation can be performed, and dehydration and the like can be performed well.
