Description
본 고안은 세탁기용 드럼커플링에 관한 것으로서, 보다 상세하게는 상기 드럼커플링의 진동을 극소화시킨 세탁기용 드럼커플링의 진동방지구조에 관한 것이다.The present invention relates to a drum coupling for a washing machine, and more particularly, to an anti-vibration structure of the drum coupling for a washing machine to minimize the vibration of the drum coupling.
일반적으로 이조식 세탁기에는 구동모터를 제동시켜주는 제동장치가 구비되는데, 이러한 세탁기의 제동장치는 상부에 샤프트를 통하여 탈수통과 연동되게 결합된 구동모터와; 상기 구동모터의 상부에 위치하여 샤프트에 고착된 원통형의 드럼커플링과; 상기 드럼커플링의 외주면으로 위치하여 일측단부에 힌지축이 설치되며, 타측단부로 와이어와 결합하되, 이 와이어는 스위치의 접점신호에 따라 당기거나 또는 해제하는 브레이크 링크에 부설되는 한편, 내주면으로 석면 또는 합성수지재로써, 내마모성 및 내열성인 라이닝이 부설된 브레이크 밴드; 등으로 구성된다.In general, the two-type washing machine is provided with a braking device for braking the driving motor. The braking device of the washing machine includes: a driving motor coupled to the dehydration container through a shaft at an upper portion thereof; A cylindrical drum coupling positioned on the drive motor and fixed to the shaft; Located on the outer circumferential surface of the drum coupling, a hinge shaft is installed at one end, and coupled to the wire at the other end, which is attached to a brake link that pulls or releases according to the contact signal of the switch, and asbestos as the inner circumferential surface. Or as a synthetic resin material, a brake band in which a lining having abrasion resistance and heat resistance is laid; And the like.
즉, 상기 구동모터 상부의 샤프트에 고착된 원통형의 드럼커플링은 일측에 연결된 와이어가 일측으로 잡아 당겨지면 브레이크 밴드 내주면으로 부설된 라이닝이 드럼커플링의 외주면과 면접촉되면서 상기 드럼커플링의 회전이 제동된다.That is, in the cylindrical drum coupling fixed to the shaft of the upper part of the drive motor, when the wire connected to one side is pulled to one side, the lining laid on the inner circumferential surface of the brake band is in surface contact with the outer circumferential surface of the drum coupling to rotate the drum coupling. Is braked.
한편, 종래 드럼커플링과 샤프트의 결합구조를 간략히 설명하면, 도 1과 같이 샤프트(11)의 외주면에 금속재질의 붓싱(12)이 결합되고, 상기 붓싱(12)의 일측에 절연재질의 고정구(미도시)가 결합된 다음, 상기 붓싱(12)의 외주면에 드럼커플링(13)이 압입된다.On the other hand, a brief description of the coupling structure of the conventional drum coupling and the shaft, as shown in Figure 1 the metal bushing 12 is coupled to the outer peripheral surface of the shaft 11, the fixture of the insulating material on one side of the bushing 12 After the (not shown) is coupled, the drum coupling 13 is pressed into the outer peripheral surface of the bushing (12).
그리고, 상기 드럼커플링(13)의 체결공(13a)에 보울트(13b)를 체결시키는데, 상기 보울트(13b)의 단부가 고정구와 접촉되어 샤프트(11)와 드럼커플링(13)과의 절연이 이루어진다.Then, the bolt 13b is fastened to the fastening hole 13a of the drum coupling 13, and an end of the bolt 13b is in contact with the fixture to insulate the shaft 11 from the drum coupling 13. This is done.
상기와 같이 드럼커플링(13)의 체결공(13a)에 보울트(13b)가 일측방에서 체결되기 때문에 드럼커플링(13)의 고속회전시 보울트(13b)에 의해 편심되므로서 탈수통이 탈수조 내벽에 충돌되어 소음이 발생할 뿐만 아니라, 드럼커플링(13)의 편심회전으로 인하여 진동이 발생되어 드럼커플링(13)의 수명을 단축시키는 등의 문제점이 있었다.As described above, since the bolt 13b is fastened to the fastening hole 13a of the drum coupling 13 from one side, the dehydration tank is dehydrated by being eccentric by the bolt 13b during the high speed rotation of the drum coupling 13. In addition to the noise generated by collision with the inner wall of the tank, vibration was generated due to the eccentric rotation of the drum coupling 13, there was a problem such as shortening the life of the drum coupling (13).
본 고안은 상기와 같은 문제점을 감안하여 창출한 것으로서, 보울트가 체결된 반대지점의 드럼커플링 일측에 편심보강재를 설치하므로서 드럼커플링의 진동을 극소화시킴과 동시에 드럼커플링의 고속회전시 편심회전으로 인하여 탈수통이 탈수조 내벽에 충돌되는 것을 방지한 세탁기용 드럼커플링의 진동방지구조를 제공함에 그 목적이 있다.The present invention was created in view of the above problems, and by installing an eccentric reinforcement on one side of the drum coupling at the opposite point where the bolt is fastened, the vibration of the drum coupling is minimized and the eccentric rotation during the high speed rotation of the drum coupling. Therefore, the object of the present invention is to provide a vibration preventing structure of a drum coupling for a washing machine which prevents the dewatering tank from colliding with the inner wall of the dehydrating tank.
