본 고안은 큰 감속비를 필요로 하는 장치, 예를 들면 혼화기, 응집기, 약품투입기 또는 오니제거기등의 정수처리 시설에 적합한 감속기에 관한 것이다.The present invention relates to a speed reducer suitable for an apparatus that requires a large reduction ratio, for example, a water purifier such as a mixer, agglomerator, chemical input or sludge remover.
본 고안은 특히, 감속기 케이싱의 중심축선상에 선치된 회전축에 한쌍의 편심캠을 상호 반대 방향으로 장착하고 이 각 편심캠의 외부에 각각 회전자재하게 감합 설치한 한쌍의 외치치차를 케이싱의 동체에 일체로 설치된 고정 내치치차에 치합하여 그 외치치차와 고정 내치치차의 치수차에 의한 차동 작용으로 외치치차를 자전시키고, 이 자전에 의한 회전력이 출력축을 통하여 취출되게 구성된 치차감속기에 있어서, 감속기의 입력축을 상기한 회전축과 일정한 축간거리를 유지하도록 편심 위치에 설치하고, 이 입력축과 외치치차의 회전축에 각각 상호 치합되도록 소치차와 가동 내치치차를 설치하여서 되는 치차 감속기에 관한 것이다.In particular, the present invention includes a pair of external tooth gears mounted on the rotation axis of the gear reducer casing in opposite directions to each other and rotatably fitted to the outside of each of the eccentric cams. In a gear reducer configured to engage with a fixed internal tooth provided integrally and rotate the external tooth by a differential action caused by the dimensional difference between the external tooth and the fixed internal tooth, and the rotational force by this rotation is extracted through the output shaft. The gear reducer is installed in an eccentric position so as to maintain a constant distance between the rotary shaft and the toothed gear and the movable internal tooth so as to mesh with each other on the input shaft and the rotary shaft of the external tooth.
종래의 이러한 종류의 치차 감속기에 있어서는 감속기의 입력축을 케이싱의 중심축선상에 도입하여 이에 외치치차를 직접 설치하였기 때문에 감속기의 감속 작용은 외치치차와 고정 내치치차의 치수차에 의한 외치치차의 자전에 의해서만 이루어지게 되어 그 감속비가 일정하게 한정되었다.In the conventional gear reducer of this type, since the input shaft of the reducer is introduced on the center axis of the casing and the external tooth is directly installed therein, the deceleration action of the reducer is caused by the rotation of the external tooth by the dimension difference between the external tooth and the fixed internal tooth. Only by means of which the reduction ratio was constantly limited.
본 고안은 그와 같은 점을 감안하여 감속기의 입력축에 외치치차를 직접 축설하지 아니하고 외치치차의 회전축과 감속기 입력축을 분리하여 양축간에 일정의 축간거리가 유지되게 편심의 위치에 입력축을 설치하고, 그 입력축과 외치치차의 회전축간에 감속용 치차들을 설치하여 입력축의 회전력이 외치치차에 전달되는 과정에서 1차 감속이 이루어지게 함으로서 보다 큰 감속비를 얻을수 있고 또한 감속기의 감속비 조정이 간편 용이하게 한 것으로, 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.In view of the above, the present invention does not directly install the external gear on the input shaft of the reducer, but separates the rotary shaft of the external gear and the reducer input shaft and installs the input shaft at the eccentric position so that a constant distance between the two axes is maintained. The reduction gears are installed between the input shaft and the rotation shaft of the external tooth gear, so that the first speed reduction is achieved in the process of transmitting the rotational force of the input shaft to the external tooth gear. When described in detail with the accompanying drawings as follows.
케이싱(1)의 중심축선상에 설치된 회전축(2)상에 한쌍의 편심캠(3)(4)을 그 정점이 180°대향되게 장착하고, 그 편심캠(3)(4)에 베어링(5)(6)를 개재하여 한쌍의 외치치차(7)(8)를 회전자재하게 감합하여 이 외치치차(7)(8)가 케이싱(1)의 동체 (1a)에 일체로 설치된 고정 내치치차(9)에 치합되게하고, 상기한 회전축(2)과 동일축선상에 설치된 출력축(10)의 원판(11)에 식설한 캐리어핀(12)을 외치치차(7)(8)에 천설된 캐리어홀(13)에 관설하여서 되는 공지의 치차 감속기에 있어서, 회전축(2)과 일정의 축간거리를 유지하도록 편심된 위치에 입력축(14)을 도입 설치하고, 그 입력축 (14)과 회전축(2)에는 각각 소치차(15)와 가동 내치치차(16)를 축설하여 소치차 (15)가 가동 내치치차(16)의 내치(16a)에 내접치합되게 한 것이다.A pair of eccentric cams 3 and 4 are mounted on a rotation axis 2 provided on the central axis of the casing 1 with their vertices facing 180 °, and the bearings 5 attached to the eccentric cams 3 and 4. A fixed internal tooth (7) (8) which is fitted integrally with the fuselage (1a) of the casing (1) by fitting a pair of external teeth (7) (8) through a (6). 9) and a carrier hole in which the carrier pin 12 implanted in the disc 11 of the output shaft 10 provided on the same axis as the rotary shaft 2 is installed in the external tooth 7 and 8. In the known gear reducer provided in (13), the input shaft 14 is introduced and installed at an eccentric position so as to maintain a constant distance between the rotary shaft 2 and the input shaft 14 and the rotary shaft 2. The gear teeth 15 and the movable tooth teeth 16 were built up, respectively, so that the gear teeth 15 may be internally engaged with the inner teeth 16a of the movable tooth teeth 16.
이와 같이 구성된 본 고안의 감속기는 입력축(14)이 회전되면 소치차(15)가 회전되면서 가동 내치치차(16)를 감속회전시키게 되고, 이 가동 내치치차(16)의 회전에 따라서 회전축(2)이 회전하면 주지된 바와 같이 한쌍의 외치치차(7)(8)가 편심캠(3) (4)에 의해 요동되면서 자전하여 2차 감속된 회전력을 출력축(10)으로 취출하게 된다.The reduction gear according to the present invention configured as described above rotates the movable internal tooth gear 16 while the input gear 14 is rotated, and rotates the movable internal tooth gear 16, and the rotation shaft 2 according to the rotation of the movable internal tooth gear 16. This rotation causes the pair of external teeth 7 and 8 to swing and rotate by the eccentric cams 3 and 4 so as to take out the secondary reduced rotational force to the output shaft 10 as is well known.
본 고안은 상술한 바와 같이 고정 내치치차와 외치치차를 치합시켜 구성되는 치차 감속기에 있어서, 감속기의 입력축을 외치치차의 회전축으로 이용하지 아니하고 입력축과 회전축간에 일정의 축간거리를 유지시켜 소치차와 가동 내치치차에 의한 감속 작용을 부가하였으므로 종래의 치차 감속기에 비하여 훨씬 큰 감속비를 비교적 간단한 구조로서 얻을 수 있을 뿐 아니라, 소치차와 가동 내치치차의 치수비를 바꾸어 주므로서 전체 감속비의 다양한 증감 조정이 간편용이하게 이루어질 수 있어 각종 정수 처리 시설용으로 특히 적합하다.The present invention is a gear reducer composed of a combination of a fixed internal tooth and an external tooth as described above, without using the input shaft of the reducer as the rotation axis of the external tooth gear, and maintains a constant shaft distance between the input shaft and the rotary shaft, and moves With the addition of the deceleration effect by the internal gear, not only can the gear ratio be much larger than that of the conventional gear reducer, but also can be obtained in a relatively simple structure, and the various gear ratios of the entire gear ratio can be easily adjusted by changing the dimension ratio between the small gear and the movable internal gear. It can be made easily and is particularly suitable for various water treatment facilities.
