Abstract
고속으로 원통형 세탁기나 탈수기를 회전시킬 때, 회전 부하가 회전 중심에 대해 비대칭적으로 분포되어 있으면 회전 중심이 진동을 한다. 회전 중심이 진동을 하면 떨림 현상으로 인한 잔고장이 발생하며 소음의 증가로 불편함을 초래하게 된다. 자석의 반발력을 이용하여 고정된 가구에 대한 회전기구의 진동과 떨림의 전달을 최소화 하였다.When rotating a cylindrical washing machine or dehydrator at high speed, the rotation center oscillates if the rotation load is distributed asymmetrically with respect to the rotation center. When the rotation center vibrates, trouble occurs due to the shaking phenomenon and causes inconvenience to increase noise. The repulsive force of the magnet was used to minimize the transmission of vibration and vibration of the rotating mechanism to the fixed furniture.

Description
〔도1〕 본 발명의 상세 예시도Fig. 1 is a detailed illustration of the present invention.
〔도2〕 본 발명의 자석 배열도[Figure 2] Magnet arrangement diagram of the present invention
회전하는 원통형 세탁기나 탈수기에 회전축에 베어링을 사용하여 지지하는 방법을 주로 사용한다.It is mainly used to support bearings on the rotating shaft in rotating cylindrical washing machines or dehydrators.
..
〔도1〕의 구성의 기본적인 원리는 같은 극성을 가진 자석끼리는 서로 반발하는 반발력을 사용하는 것이다.The basic principle of the configuration of Fig. 1 is to use repulsive forces that repel each other with the same polarity.
〔A원통〕의 외벽에 자석을 〔그림1〕의 〔그림C〕와 같이 같은 극성이 되도록 〔B원통〕의 내벽에 각기 다른 자석을 마주보도록 설치하면 〔A원통〕과 〔B원통〕이 서로 반발하여 〔A원통〕의 축(軸, shaft)은 〔B원통〕과 〔A원통〕의 축(shaft)에 있게 된다. 〔A원통〕이 회전할 때 〔A원통〕의 내부에 내용물을 심게 되며 축을 중심으로 내용물로 인하여 불평형 회전부하가 생기게 되고, 불평형으로 인한 떨림이 생기게 된다. 이러한 떨림은 회전기기를 제어하는 기계장치 및 제어기에 열화를 가져와 고장의 원인이 된다. 따라서 〔A원통〕과 〔B원통〕에 〔도1〕과 같이 자석을 설치하면 〔도1〕의 〔그림C〕와 같은 방법으로 〔원통A〕는 회전축(shaft)의 중심에 있게 되고, 〔도1〕의 〔그림d〕와 〔그림e〕는 원통이 회전하는 중에 전후(앞뒤)로 진동하여 부딪히는 현상을 막아준다. 즉 〔원통A〕는 자석의 반발력으로 인하여 공중에 떠있게 되어, 회전 불평형 부하로 인한 떨림과 전후(앞뒤)로 진동하여 부딪히는 현상을 막고, 〔A원형〕은 고정시키는 줄이 따로 필요치 않게된다.If the magnets are placed on the outer wall of [A cylinder] so as to face different magnets on the inner wall of [B cylinder] so as to have the same polarity as [Fig. C] of [Fig. 1], [A cylinder] and [B cylinder] In response, the shaft of [A cylinder] is in the shaft of [B cylinder] and [A cylinder]. When the cylinder [A] rotates, the contents are planted inside the cylinder [A] and an unbalanced rotational load is generated due to the contents around the axis, resulting in vibration due to unbalance. Such tremors may cause deterioration of machinery and controllers that control the rotating machine and cause failure. Therefore, if the magnets are installed in the [A cylinder] and the [B cylinder] as shown in [Fig. 1], [A] will be in the center of the shaft by the same method as [Fig. C] of [Fig. 1]. Fig. 1 and Fig. 1 of Fig. 1 prevent the cylinder from vibrating and hitting back and forth (back and forth) while the cylinder is rotating. That is, [Cylinder A] floats in the air due to the repulsive force of the magnet, thereby preventing the vibration caused by the unbalanced rotational load and vibrating and hitting back and forth (front and back), and the [Circular A] does not need to be fixed separately.
〔도2〕는 〔A원통〕과 〔B원통〕의 자석의 배열에 대한, 단면도를 보여주고 있다. 〔BA원통의 좌측자석 배열도〕는 〔A원통〕과 〔B원통〕의 각기 다른 자석을 동시에 나타내 보인 것이고, 〔B,A원통의 우측자석배열도〕는 〔A원통〕과 〔B원통〕의 각기 다른 자석을 동시에 나타내 보인 것으로, 틈(gap) [d〕를 사이에 두고 겹쳐서 나타내 보인 자석의 배열도이다.Fig. 2 shows a sectional view of the arrangement of the magnets of [A cylinder] and [B cylinder]. [Left magnet arrangement diagram of BA cylinder] shows different magnets of [cylinder A] and [cylinder B] at the same time, [right magnet arrangement of B, A cylinder] is [A cylinder] and [B cylinder] The different magnets are shown simultaneously, and the arrangement of the magnets is shown by overlapping the gap [d].
〔〔A원통〕,〔B원통〕의 단면을 90˚회전시킨 자석 배치도〕는 〔A원통〕을 1번중심선인 축(shaft) 중심에 있도록 하는 자석배치를 나타내기 위하여 ②번 단면을 내어 90˚ 회전시켜서 나타내 보인 것이다.[A magnet arrangement diagram in which the sections of the cylinder A and the cylinder B are rotated by 90 °] is shown in FIG. 2 to show the magnet arrangement in which the cylinder A is located at the center of the shaft, which is the number 1 center line. It is shown by rotating ˚.
A원통이 회전축인 ①번 중심선에 항상 있도록 자석의 반발력을 이용하여 〔A원통〕이 공중에 떠있도록 하여 에너지 절감 효과와, 회전부하의 불균일로 인한 떨 림과 진동이 〔B원통〕에 영향을 주지 않도록 하여 떨림과 진동을 억제하여 기기의 내구성을 높이었다.By using the repulsive force of the magnet so that the cylinder A is always at the centerline of ①, which is the axis of rotation, the [A cylinder] floats in the air, and the energy saving effect and the vibration and vibration caused by the uneven rotation load affect the [B cylinder]. The vibration and vibration are suppressed and the durability of the device is increased.
