Description
본 발명은 예로, 믹서기(주서기)의 동력전달축상에 설치되는 누수방지용 리테이너에 관한 것으로, 특히 축계의 수압이 증가할수록 누수방지성이 증가하고 내마모성을 향상시키도록 한 누수방지용 리테이너 및 이를 이용한 믹서기의 누수방지구조에 관한 것이다.The present invention relates to, for example, a leak preventing retainer installed on a power transmission shaft of a mixer (juicer), and in particular, a leak preventing retainer and a blender using the same to improve leakage resistance as the water pressure of the shaft system increases. It relates to a leak prevention structure of.
일반적으로 믹서기에서와 같이 주스액을 만들어내기 위해서는 주서컵내에 분쇄커터가 위치해 있어야 하고, 이 분쇄커터는 구동모터와 동력전달축으로 연결되어 있어야 한다.In general, a grinding cutter must be placed in the juicer cup to make juice, as in a blender. The grinding cutter must be connected to the drive motor and the power transmission shaft.
따라서 분쇄커터와 동력전달축을 연결하는 부분은 실제로 가공물을 믹싱,분쇄할 경우 가공물의 분쇄된 액체상의 주스액에 노출되게 된다.Therefore, the part connecting the grinding cutter and the power transmission shaft is exposed to the pulverized liquid juice of the workpiece when the workpiece is actually mixed and ground.
따라서 이 주스액이 동력전달축계로 들어가면 동력전달축의 부식뿐만 아니라 구동모터의 내구성 및 믹서기의 품질을 떨어뜨리는 결과를 초래한다.Therefore, when the juice liquid enters the power transmission shaft system, not only the power transmission shaft is corroded, but also the durability of the driving motor and the quality of the mixer are reduced.

도 1은 본 발명에 따른 누수방지용 리테이너(20)의 단면도를 나타내고 있다.1 is a cross-sectional view of the leak-proof retainer 20 according to the present invention.
본 발명의 리테이너(20)는, 회전동력 전달축계에 사용되는 누수방지용 부품으로서, 고무 또는 실리콘 재질중 어느 하나로 택일하여 성형된다.The retainer 20 of the present invention is a leakage preventing component used in a rotational power transmission shaft system, and is molded by any one of rubber or silicone materials.
리테이너(20)는 외측원통부(22)와, 외측원통부(22)의 하단에서 내측으로 연결부(23)를 통해 연장되고 축선(1)상으로 상향 경사지게 입설된 원추형의 내측원통부(24)와, 상기 내측원통부(24)의 상단 내측에 도 2의 동력전달축(10)과 선접촉하는 호형부(25)를 구비하고 있다.The retainer 20 extends through the connecting portion 23 from the lower end of the outer cylindrical portion 22 and the outer cylindrical portion 22 to the inner side, and has a conical inner cylindrical portion 24 inclined upwardly on the axis 1. And an arc portion 25 which is in linear contact with the power transmission shaft 10 of FIG. 2 inside the upper end of the inner cylindrical portion 24.
상기 리테이너(20)는 고무 또는 실리콘으로 제작되므로, 외측원통부(22)뿐만 아니라 내측원통부(24)도 탄성 반발력을 가지고 있게 된다.Since the retainer 20 is made of rubber or silicon, not only the outer cylindrical portion 22 but also the inner cylindrical portion 24 will have elastic repulsive force.
이때 바람직하게는 외측원통부(22)의 상면을 둥글게 호형으로 형성하여 후술할 도2의 베어링 지지외통(56)의 내측 상면과 탄력있게 밀착하도록 한다.At this time, preferably, the upper surface of the outer cylindrical portion 22 is formed in a circular arc shape so as to be in close contact with the inner upper surface of the bearing support outer cylinder 56 of FIG. 2 to be described later.
그리고 내측원통부(24)의 호형부(25)의 둘레내경은 조립될 축의 직경보다는 적어도 작도록 하여 탄력적으로 이 호형부(25)가 축에 밀착하도록 구성한다.And the inner diameter of the arc portion 25 of the inner cylindrical portion 24 is configured to be at least smaller than the diameter of the shaft to be assembled so that the arc portion 25 is in close contact with the shaft.
이와 같이 구성된 누수방지용 리테이너(20)의 작용은 후술할 믹서기의 누수방지구조에서 설명될 것이다.The action of the leak-proof retainer 20 configured as described above will be described in the leak-proof structure of the mixer to be described later.
도 2는 본 발명의 리테이너(20)가 분쇄커터(52)를 회전시키는 축받이부(54)의 회전축(10)상에 설치된 조립구조를 나타내고 있다.2 shows an assembly structure in which the retainer 20 of the present invention is provided on the rotation shaft 10 of the bearing portion 54 for rotating the grinding cutter 52.
도면 부호 54는 믹서기의 축받이부(54)로서, 미리 제작된 베어링 지지외통 (56)과 사출성형된다.Reference numeral 54 denotes a bearing 54 of the mixer, which is injection molded with a bearing bearing outer cylinder 56 prepared in advance.
즉, 상기 베어링 지지외통(56)은 상기 축받이부(54)의 사출성형 완료시 축받이부(54) 중앙에 입설된다.That is, the bearing support outer cylinder 56 is placed in the center of the bearing portion 54 when the injection molding of the bearing portion 54 is completed.
상기 베어링 지지외통(56)의 내측 상부에 상기 누수방지용 리테이너(20)가 삽입되어 있고, 또 베어링 지지외통(56)의 내측에 상기 리테이너(20)를 지지하는 축지지베어링(58)(일명 '오일리스 메탈'이라고 함)이 강제 압입되어 있다.The leakage preventing retainer 20 is inserted into the upper portion of the bearing support outer cylinder 56, and the shaft support bearing 58 for supporting the retainer 20 inside the bearing support outer cylinder 56 (aka ' Oilless metal) 'is press-fitted.
즉, 상기 베어링 지지외통(56)과 축지지베어링(58)의 사이에 누수방지용 리테이너(20)가 개재되어 있다.That is, the leak-proof retainer 20 is interposed between the bearing support outer cylinder 56 and the shaft support bearing 58.
따라서 리테이너(22)의 상면은 베어링지지외통(56)의 내측상면에 밀착되고, 리테이너(22)의 호형부(25)가 회전축(10)의 외주면에 선접촉으로 밀착된다.Therefore, the upper surface of the retainer 22 is in close contact with the inner upper surface of the bearing support outer cylinder 56, and the arc portion 25 of the retainer 22 is in close contact with the outer circumferential surface of the rotation shaft 10 in linear contact.
이와 같이 조립된 믹서기의 누수방지 구조 및 리테이너의 작용효과를 함께설명한다.The leakage preventing structure and retainer effect of the mixer thus assembled will be described together.
먼저, 도 2와 같이 믹서기의 주서컵(3)에 분쇄물을 넣고 분쇄가공이 시작되면 도시안된 구동모터에 연결된 회전축(10)의 회전력에 의해 분쇄커터(52)가 회전한다.First, as shown in FIG. 2, when the pulverized product is put into the juicer cup 3 of the mixer and the grinding process is started, the grinding cutter 52 is rotated by the rotational force of the rotating shaft 10 connected to the driving motor (not shown).
분쇄커터(52)가 회전하면 주서컵내에 내압이 증가하게 되는데, 이 내압은 분쇄커터(52)의 하방측 회전축(10)에도 영향을 주게 된다.When the grinding cutter 52 rotates, the internal pressure increases in the juicer cup, and this internal pressure also affects the lower rotating shaft 10 of the grinding cutter 52.
즉, 이 내압은 베어링 지지외통(56)과 회전축(10)과의 사이를 통해 리테이너 (20)를 상부에서 하부로 누름하는 힘으로 작용한다.That is, this internal pressure acts as a force which presses the retainer 20 from the upper part to the lower part between the bearing support outer cylinder 56 and the rotating shaft 10.
이때 리테이너(20)는 플렉시블한 탄력소재로 되어 있어, 내측원통부(24)의 호형부(25)가 회전축(10)과 선접촉한 상태에서 더욱 밀착된 선접촉으로 작용하게 된다.At this time, the retainer 20 is made of a flexible resilient material, and the arc portion 25 of the inner cylindrical portion 24 acts in closer contact with the rotary shaft 10 in line contact.
따라서 본 발명에 의하면 믹서기의 분쇄작업중에 더욱더 누수방지의 효과가 나타나게 된다. 물론 분쇄커터(52)가 회전하지 않고 있는 경우에도 리테이너(20)의 내측원통부(24)의 호형부(25)가 회전축(10)과 밀착되어 있어 누수는 발생되지 않는다.Therefore, according to the present invention, the effect of preventing leakage is further exhibited during the grinding operation of the mixer. Of course, even when the grinding cutter 52 is not rotating, the arc 25 of the inner cylindrical portion 24 of the retainer 20 is in close contact with the rotating shaft 10, so that no water leakage occurs.
더욱이 회전축(10)의 회전시에도 리테이너(20)와 회전축(10)이 접촉하는 면적이 적기 때문에 마찰력이 거의 없고 쉽게 마모도 일어나지 않아 내마모성이 우수하다.In addition, even when the rotating shaft 10 rotates, the retainer 20 and the rotating shaft 10 have a small area in contact with each other, so that there is little frictional force and wear does not easily occur.
상술한 바와 같이 본 발명에 의하면, 항시 리테이너가 회전축에 선접촉으로밀착되어 있어 누수방지가 우수하고, 또 외부압력의 작용시에도 누수부분에서의 수밀성이 향상되므로, 믹서기의 주서컵내의 압력 상승시에도 누수억제의 증진효과를 기대할 수 있다.As described above, according to the present invention, the retainer is always in close contact with the rotary shaft in line contact, so that the leak is excellent, and the watertightness at the leaking part is improved even when the external pressure is applied. It can be expected to improve leakage control.
