Description
본 고안은 건물의 셔터를 내려주거나 올려주는데 사용되는 감속장치에 관한 것이다.The present invention relates to a reduction device used to lower or raise a shutter of a building.
종래의 감속장치는 도 1에 도시된 바와 같이 한쪽끝에 표현이 생략된 셔터권취축과 체인으로 전동되는 구동스프로켓휘일(1)이 고정된 주축(2)의 다른쪽끝에 있는 큰기어(3)와 맞물려지는 작은 기어(4)가 동일축(5)에 있는 큰기어(6)를 회전시켜주는 모터축(7)의 단부에 있는 기어(8)를 상기 큰기어(6)와 단순히 맞물려지도록한 것이어서 즉, 모터축(7)의 기어(8) 윗쪽만이 하우징(9)에 베어링(10)으로 단순히 지지된 것이었기 때문에 기어(8)쪽에 비틀림하중이 집중적으로 작용하게 되어서 기어(8)의 마모가 크게 일어나게 되고 오래사용할 경우 기어(8)와 큰기어(6)의 맞물림상태가 불량하게 되어서 기어(8)가 공회전을 하게 되므로 셔터가 원하지 않게 닫혀져서 안전사고를 초래했었고, 모터축(7)의 수명주기가 단축되어서 유지,보수 비용이 많이들었었을뿐만 아니라 셔터의 가동중지시간이 많아지게 되는 등의 문제점이 있었다.As shown in FIG. 1, a conventional gear reduction apparatus includes a shutter winding shaft at which one end is omitted, and a large gear 3 at the other end of the main shaft 2 to which the drive sprocket wheel 1 is driven by a chain. The gear 8 at the end of the motor shaft 7 which causes the small gear 4 to be engaged to rotate the large gear 6 on the same shaft 5 is simply engaged with the large gear 6. That is, since only the upper part of the gear 8 of the motor shaft 7 was simply supported by the bearing 10 on the housing 9, the torsional load acted intensively on the gear 8 side, and the wear of the gear 8 occurred. If the long time use occurs and the gear 8 and the large gear 6 are in poor engagement, the gear 8 is idle and the shutter is undesired. It was closed and caused a safety accident, and the life cycle of the motor shaft 7 was shortened, which caused a lot of maintenance and repair costs, as well as a problem of increasing the downtime of the shutter.
본 고안은 이와같은 종래기술의 제반문제점을 해결한 것인바, 본 고안은 모터축의 기어와 큰기어와의 맞물려진 상태가 변형되지 않도록 모터축의 자유단부쪽을 지지해줌으로서 기어들의 결합상태불량으로 인한 안전사고를 방지하고 내구수명을 연장시켜줌으로서 유지,보수비용을 절감하여 셔터의 가동율을 향상시켜줄 수 있는 건물용셔터의 감속장치를 제공하는데 기술적과제를 둔 것이다.The present invention solves all the problems of the prior art. The present invention supports the free end of the motor shaft so that the meshed state of the gear and the large gear of the motor shaft is not deformed. The technical problem is to provide a deceleration device for building shutters that can improve the operation rate of the shutter by reducing the maintenance and repair costs by preventing safety accidents and extending the service life.

도 2 는 본 고안에 의한 감속장치의 횡단면도.Figure 2 is a cross-sectional view of the reduction device according to the present invention.
도 3 은 본 고안에 의한 감속장치의 요부를 보인 분해사시도.Figure 3 is an exploded perspective view showing the main portion of the reduction device according to the present invention.
본 고안은 도 2 와 도 3에 예시한 바와 같이 구동스프로켓휘일(1)이 고정된 주축(2)에 있는 큰기어(3)와 맞물려지는 작은기어(4)가 동일축(5)에 있는 큰기어(6)를 , 하우징(9)에 베어링(10)으로 지지되는 모터축(7)의 단부에 있는 기어(8)와 맞물려지도록 한 것에 있어서, 주축(2)의 큰기어(3)중앙에는 원형요입부(11)를 형성시켜서 베어링(12)의 외륜(13)을 억지끼워맞춤하고, 모터축(7)의 기어(8)쪽에는 상기 모터축(7)과 같은 축선상으로 길게 연장된 단부(14)를 형성시켜서 상기 베어링(12)의 내륜(15)속에 상기 모터축(7)의 연장된 단부(14)를 억지 끼워맞춤하여서 주축(2)의 큰기어(3)와 맞물려지는 모터축(7)에 있는 기어(8)의 양쪽을 모두 베어링(9)과 베어링(12)으로 회전이 자유롭도록 지지하여서된 것이다.2 and 3, a small gear 4 meshing with a large gear 3 in the main shaft 2, to which the drive sprocket wheel 1 is fixed, has a large shaft in the same axis 5, as illustrated in FIGS. The gear 6 is engaged with the gear 8 at the end of the motor shaft 7 supported by the bearing 10 on the housing 9. In the center of the large gear 3 of the main shaft 2 The circular recess 11 is formed to forcibly fit the outer ring 13 of the bearing 12, and the gear 8 side of the motor shaft 7 extends long on the same axis as the motor shaft 7. A motor engaged with the large gear 3 of the main shaft 2 by forming an end 14 to forcibly fit the extended end 14 of the motor shaft 7 into the inner ring 15 of the bearing 12. Both of the gears 8 on the shaft 7 are supported by the bearing 9 and the bearing 12 so that rotation is free.
이와 같이 구성된 본 고안에 의한 감속장치는 기어(8)의 양쪽 모두가 베어링(9)과 베어링(12)으로 지지된 것이어서 주축(2)의 큰기어(3)와 맞물려진 상태에서 회전할때 비틀림하중이 모터축(7)에 고르게 분산작용 되기 때문에 모터축(7)이 편심되거나 파손될 우려가 방지되고, 기어(8)와 큰기어(3)의 맞물려진 상태가 균일하게 유지되어서 기어(8)와 큰기어(3)의 마모도를 감소시켜준다.The reduction device according to the present invention configured as described above is torsion when both of the gears 8 are supported by the bearing 9 and the bearing 12 so as to rotate in the engaged state with the large gear 3 of the main shaft 2. Since the load is distributed evenly on the motor shaft 7, the motor shaft 7 is prevented from being eccentric or broken, and the engaged state of the gear 8 and the large gear 3 is kept uniform so that the gear 8 And reduce the wear of the large gear (3).
본 고안은 기어들의 결합상태불량으로 인한 안전사고를 방지할수 있고, 내구수명주기를 연장시켜줌으로서 유지보수비용을 절감할 수 있으며, 유지보수주기 또한 연장시켜줌으로서 셔터의 가동율도 향상시켜 줄 수 있는 등의 장점이 있다.The present invention can prevent safety accidents due to poor coupling state of the gears, reduce the maintenance cost by extending the durability life cycle, and improve the operation rate of the shutter by extending the maintenance cycle. Has the advantage.
