Description

댐퍼 작동기Damper actuator
본 발명은 댐퍼 작동기에 관한 것으로서, BLDC 모터를 이용하여 낮은 감속비로 기동 토크를 구현하고, 감속 구조의 단순화와 내구성 향상을 달성할 수 있는 댐퍼 작동기에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a damper actuator, and more particularly, to a damper actuator capable of realizing starting torque at a low reduction ratio using a BLDC motor, and achieving simplification and durability improvement of the reduction structure.
덕트의 개폐와 풍량 제어의 용도로 풍량조절 댐퍼, 방화 댐퍼, 릴리프 댐퍼, 전동 댐퍼 등 다양한 형태의 공조용 댐퍼가 사용되고 있으며, 이러한 댐퍼는 일반적으로 댐퍼 작동기에 의해 구동된다.Various types of air conditioning dampers, such as air flow control dampers, fire dampers, relief dampers, and electric dampers, are used for opening and closing of the duct and controlling the air volume, and these dampers are generally driven by damper actuators.
일반적으로 댐퍼는 작업자가 진입하기 어려운 곳에 설치되기 때문에 댐퍼를 구동시키는 댐퍼 작동기의 내구성이 매우 중요시된다.In general, since the damper is installed where it is difficult for workers to enter, the durability of the damper actuator for driving the damper is very important.
그러나, 종래에 사용되던 일반적인 댐퍼 작동기는 일반적인 동기모터를 사용하기 때문에, 댐퍼 구동을 위한 토크를 얻기 위한 감속구조가 복잡하였으며, 이와 같은 복잡한 감속 구조로 인해 고장이 발생하는 사례가 많이 발생하였다.However, since a conventional damper actuator uses a conventional synchronous motor, a deceleration structure for obtaining a torque for driving a damper is complicated, and many cases of failure occur due to such a complicated deceleration structure.
또한, 외부에서 동기모터로 전달되는 전기가 차단되거나, 댐퍼 작동기의 고장이 발생하는 경우 댐퍼를 수동으로 개폐하기 위한 방안으로, 댐퍼 작동기 구동시의 에너지를 기계식 스프링에 저장하고 이를 이용하여 댐퍼를 개방하는 방식이 사용되었으나, 이러한 방식은 화재 발생 시 지정된 각각의 구역을 차단해야 하는 방화 댐퍼와, 화재 발생 시 내부에 가득 찬 연기를 외부로 배출하기 위해 개방 되어야 하는 풍량조절 댐퍼와 같이, 서로 상반된 목적을 가지는 댐퍼에 적용할 수 없는 문제점을 가지고 있었다.In addition, when the electric power transmitted to the synchronous motor is cut off from the outside or the damper actuator breaks down, the damper actuator is opened and closed manually. The energy of the damper actuator is stored in a mechanical spring and the damper is opened by using the damper actuator. However, these methods have mutually different objectives, such as a fire damper that must shut off each designated area in the event of a fire, and an airflow damper that must be opened to discharge the full smoke inside. There was a problem that can not be applied to the damper.
이와 같은 문제를 해결하고자 도 1에 도시된 바와 같이 모터(20)를 이용하여 댐퍼(10)와 연결된 덕트를 개방되고, 복귀 스프링(60)을 이용하여 덕트를 폐쇄할 수 있는 양방향성 댐퍼장치가 개발되었으나, 덕트 폐쇄 시 복귀 스프링(60)의 탄성력을 이용하므로 댐퍼 작동기의 근본적인 내구성 문제를 해결할 수 없는 또 다른 문제를 야기하고 있다.In order to solve such a problem, as shown in FIG. 1, a bidirectional damper device is developed to open a duct connected to the damper 10 using a motor 20 and to close the duct using a return spring 60. However, since the elastic force of the return spring 60 is used when the duct is closed, it causes another problem that cannot solve the fundamental durability problem of the damper actuator.
이에, 댐퍼 작동기의 구조를 단순화하여 내구성을 향상시키면서고 긴급상황 발생시 각각의 댐퍼 사용의 목적에 따라 구동될 수 있는 댐퍼 작동기의 개발이 필요하다.Accordingly, there is a need to develop a damper actuator that can be driven according to the purpose of using each damper in an emergency situation while improving durability by simplifying the structure of the damper actuator.
본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로써 본 발명의 목적은, 댐퍼 작동기를 단순화시켜 댐퍼 작동기의 내구성을 향상시키고, 댐퍼 작동기에 문제가 발생하더라도 상황에 대응하여 댐퍼 작동기를 구동시킬 수 있는 댐퍼 작동를 제공하는 것이다.The present invention has been made to solve the above problems, the object of the present invention is to improve the durability of the damper actuator by simplifying the damper actuator, even if a problem occurs in the damper actuator to drive the damper actuator in response to the situation To provide damper operation.
본 발명은 상기와 같은 문제점을 해결하기 위해 직류 브러쉬리스(BLDC)모터를 사용하여 단순한 감속기어 체계를 구현하였으며, 모터제어를 위한 별도의 센서를 구비하지 않고, 거대자기저항 센서(GMR 센서)를 이용하여 모터제어와 회전력 제어를 구현하고, 별도의 배터리를 구비하여 외부 전원 차단시 개폐 구동이 가능하도록 하는 기술적 해결방법을 제안하였다.The present invention implements a simple reduction gear system using a DC brushless (BLDC) motor to solve the above problems, and does not include a separate sensor for controlling the motor, and employs a large magnetoresistive sensor (GMR sensor). By using the motor control and rotational force control, and a separate battery has been proposed a technical solution to enable the opening and closing drive when the external power is cut off.
이에 본 발명의 댐퍼 작동기는, 직류 브러쉬리스(BLDC)모터를 사용하여, 복잡한 감속기어 체계를 단순화시켜 장치의 내구성을 향상시킬 수 있는 효과를 갖는다.Accordingly, the damper actuator of the present invention has the effect of improving the durability of the device by simplifying a complicated reduction gear system using a DC brushless (BLDC) motor.

도 3과 도 4를 참조하여 설명하면, 본 발명인 댐퍼 작동기는 상기 모터 조립체(100)가 외부에서 전기를 입력받아 회전 운동하는 직류 브러쉬리스(BLDC) 모터(110)와, 상기 직류 브러쉬리스 모터(110)에서 전달된 회전력을 감속 시키는 유성기어장치(120)로 이루어지고, 상기 복합 기어부(200)는 상기 유성기어장치(120)에서 전달된 회전 운동의 방향을 바꾸는 웜기어(210)와, 상기 웜기어(210)에서 회전력을 전달받아 동일 회전축(221)에 끼워진 평기어(230)를 회전시키는 스퍼기어(220)와, 상기 평기어(230)에서 회전력을 전달받는 섹션기어(240)를 포함하며, 상기 구동 출력부(300)는 상기 섹션기어(240)의 회전축에 고정된다.Referring to Figures 3 and 4, the damper actuator of the present invention is a direct current brushless (BLDC) motor 110 and the direct current brushless motor (110) that the motor assembly 100 is rotated by receiving electricity from the outside ( The planetary gear device 120 to reduce the rotational force transmitted from the 110, the composite gear unit 200 is a worm gear 210 for changing the direction of the rotational motion transmitted from the planetary gear device 120, and It includes a spur gear 220 for receiving a rotational force from the worm gear 210 to rotate the spur gear 230 fitted to the same rotation shaft 221, and a section gear 240 for receiving the rotational force from the spur gear 230. The driving output unit 300 is fixed to the rotation shaft of the section gear 240.
상세히 설명하면, 도 3에 도시된 바와 같이 상기 직류 브러쉬리스 모터(110)가 외부에서 전기 에너지를 입력받아 회전하게 되면, 상기 유성기어장치(120)에서 직류 브러쉬리스 모터(110)에서 전달되는 회전력을 감속시켜 토크를 1차적으로 증가시킨다. 즉, 회전속도를 줄이고 파워밀도를 증가시키는 것이다.In detail, when the DC brushless motor 110 is rotated by receiving electric energy from the outside, as shown in FIG. 3, the rotational force transmitted from the DC brushless motor 110 to the planetary gear device 120. Decrease to increase torque primarily. In other words, to reduce the rotation speed and increase the power density.
또한, 상기 유성기어장치(120)에서 상기 웜기어(210)로 전달된 회전력은 웜기어(210)와 스퍼기어(220)를 통해 회전 방향이 수직 변환되어 상기 구동 출력부(300)와 같은 회전 방향을 이루게 한다. 즉, 웜기어(210)와 스퍼기어(220)를 이용해 상기 직류 브러쉬리스 모터(110)에서 전달되는 회전력의 방향을 상기 구동 출력부(300)의 회전 방향으로 변환 시키는 것이다.In addition, the rotational force transmitted from the planetary gear device 120 to the worm gear 210 is vertically converted into a rotational direction through the worm gear 210 and the spur gear 220 so that the rotational direction is the same as that of the driving output unit 300. To achieve. That is, the direction of rotational force transmitted from the DC brushless motor 110 is converted into the rotational direction of the driving output unit 300 by using the worm gear 210 and the spur gear 220.
이때, 상기 웜기어(210)와 상기 스퍼기어(220)의 기어 비에 따라 2차 감속이 발생할 수 있다.In this case, secondary deceleration may occur according to the gear ratio of the worm gear 210 and the spur gear 220.
그리고, 도 4를 참조하여 설명하면 상기 스퍼기어(220)는 회전축(221)의 길이방향 일측이 상기 하부 하우징(420)의 내면 하측에 위치되는 제1 회전 베어링(421)에 끼워지고, 길이방향 타측이 하부 하우징(420)의 내면 하측에서 상측으로 연장 형성된 복수개의 지지봉(422)의 상측에 결합된 제2 회전 베어링(423)에 끼워진다.In addition, referring to FIG. 4, the spur gear 220 is fitted with a first rotary bearing 421 located at one side of the longitudinal axis of the rotary shaft 221 below the inner surface of the lower housing 420. The other side of the lower housing 420 is fitted to the second rotary bearing 423 coupled to the upper side of the plurality of support rods 422 extending upward from the lower side.
즉, 상기 회전축(221)은 길이방향 일측 단부가 상기 제1 회전 베어링(421)에 끼워지고, 길이방향 타측이 상기 제2 회전 베어링(423)에 끼워져, 상하 길이방향과 수직을 이루는 평면상에서 원주방향으로 회전하는 것이다.That is, the rotary shaft 221 is one end in the longitudinal direction is fitted into the first rotary bearing 421, the other in the longitudinal direction is fitted in the second rotary bearing 423, the circumference on the plane perpendicular to the vertical longitudinal direction To rotate in the direction.
이때, 상기 스퍼기어(220)는 상기 회전축(221)의 상측에 끼워져 상기 웜기어(210)에서 회전력을 전달받으며, 스퍼기어(220)의 회전력에 의해 회전축(221)이 회전하며 회전축(221)의 하측에 끼워진 평기어(230)를 회전시킨다. 그리고, 상기 스퍼기어(220)와 상기 평기어(230)의 톱니 수에 따라 3차 감속이 발생된다.At this time, the spur gear 220 is fitted to the upper side of the rotary shaft 221 receives the rotational force from the worm gear 210, the rotary shaft 221 is rotated by the rotational force of the spur gear 220 and the rotary shaft 221 The spur gear 230 fitted to the lower side is rotated. In addition, the third reduction is generated according to the number of teeth of the spur gear 220 and the spur gear 230.
또한, 상기 평기어(230)는 도 5에 도시된 바와 같이 섹션기어(240)에 회전력을 전달해 부채 형상의 섹션기어(240)의 회전축에 고정된 구동 출력부(300)를 회전 시킨다.In addition, the spur gear 230 transmits a rotational force to the section gear 240 as shown in FIG. 5 to rotate the drive output unit 300 fixed to the rotating shaft of the fan-shaped section gear 240.
상세히 설명하면, 본 발명인 댐퍼 작동기는 덕트에 구비되는 댐퍼를 개폐하기 위한 장치로서, 댐퍼의 구동축을 회전시켜 댐퍼를 개폐하며, 댐퍼 개폐를 위해 댐퍼의 구동축을 약 90도 회전시키면 충분하지만 다양한 댐퍼를 개폐하기 위해 높은 토크를 만들어야 한다.In detail, the damper actuator of the present invention is a device for opening and closing the damper provided in the duct, by rotating the drive shaft of the damper to open and close the damper, it is enough to rotate the drive shaft of the damper about 90 degrees to open and close the damper, but various dampers High torque must be made to open and close.
따라서, 상기 직류 브러쉬리스 모터(110)를 이용함으로써 일반 모터에 비해 모터에서 생성되는 토크를 향상 시켜 상기 기어부(200)의 감속 구조를 단순화하고, 상기 유성기어장치(120) 및 상기 복합 기어부(200)를 통해 직류 브러쉬리스 모터(110)에서 전달되는 회전력을 감속시키되 토크를 향상시켜 상기 구동 출력부(300)에 고정된 댐퍼의 구동축을 회전시키기 충분한 회전력을 생성하며, 댐퍼의 구동축이 지나치게 회전하여 댐퍼가 고장나는 것을 방지하고자 댐퍼의 구동축을 부채 형상을 가지는 섹션기어(240)의 회전축(241)에 고정시키는 것이다.Therefore, by using the DC brushless motor 110 to improve the torque generated in the motor compared to the general motor to simplify the deceleration structure of the gear unit 200, the planetary gear device 120 and the composite gear unit While reducing the rotational force transmitted from the DC brushless motor 110 through the (200) to improve the torque to generate a rotational force sufficient to rotate the drive shaft of the damper fixed to the drive output unit 300, the drive shaft of the damper is excessive In order to prevent the damper from malfunctioning by rotating, the driving shaft of the damper is fixed to the rotating shaft 241 of the section gear 240 having a fan shape.
이때, 댐퍼의 구동축은 상기 섹션기어(240)의 회전축에 고정되면 충분하지만 상기 구동 출력부(300)를 통해 다양한 형상을 가지는 댐퍼의 구동축을 섹션기어(240)의 회전축(241)에 손쉽게 결합시킬 수 있다.At this time, the drive shaft of the damper is sufficient to be fixed to the rotation shaft of the section gear 240, but the drive shaft of the damper having a variety of shapes through the drive output unit 300 can be easily coupled to the rotation shaft 241 of the section gear 240. Can be.
도 6을 참조하여 설명하면, 상기 구동 출력부(300)는 댐퍼의 구동축을 고정 시키는 상부 플렌지(310)와 섹션기어(240)의 회전축에 끼워지는 하부 플렌지(320)로 구분되고, 상부 플렌지(310)와 하부 플렌지는 클램핑 볼트(330)를 통해 결합된다.Referring to FIG. 6, the drive output unit 300 is divided into an upper flange 310 for fixing the drive shaft of the damper and a lower flange 320 fitted to the rotation shaft of the section gear 240, and an upper flange ( 310 and the lower flange are coupled via the clamping bolt 330.
도 4를 참조하여 상세히 설명하면, 상기 하부 플렌지(320)는 상측에 원주 방향으로 상기 섹션기어(240)의 회전축(241)보다 큰 직경을 가지는 제1 돌기(321)가 형성되어, 상기 제1 돌기(321)의 하면이 상기 회전축(241)의 상면에 안착되고, 하측이 섹션기어(240)의 회전축(241)에 삽입되며, 상하 방향으로 댐퍼의 구동축이 끼워지는 결합공(322)이 형성되되, 상기 결합공(322)과 접촉하는 내면(323)이 상측에서 하측으로 갈수록 내경이 좁아지는 테이퍼 형상의 구조를 가진다.Referring to FIG. 4, the lower flange 320 has a first protrusion 321 having a diameter larger than that of the rotation shaft 241 of the section gear 240 in the circumferential direction. The lower surface of the projection 321 is seated on the upper surface of the rotary shaft 241, the lower side is inserted into the rotary shaft 241 of the section gear 240, the coupling hole 322 is formed to fit the drive shaft of the damper in the vertical direction.

또한, 상기 상부 플렌지(310)는 하측이 상기 하부 플렌지(320)의 결합공(332)에 끼워지고, 상측에 하부 플렌지(320)의 제1 돌기(321)에 대응하는 제2 돌기(311)가 형성되며, 상기 제1 돌기(321)와 제2 돌기(311)가 상기 클램핑 볼트(330)로 연결된다.In addition, the upper flange 310 has a lower side fitted into the coupling hole 332 of the lower flange 320, and the second protrusion 311 corresponding to the first protrusion 321 of the lower flange 320 on the upper side. Is formed, and the first protrusion 321 and the second protrusion 311 are connected to the clamping bolt 330.
즉, 상기 클램핑 볼트(330)를 이용해 상기 제1 돌기(321)와 상기 제2 돌기(311)의 상하 이격 거리를 좁힐 시, 테이퍼 형상의 구조를 가지는 상기 하부 플렌지(320)의 내면(323)이 상기 상부 플렌지(310)의 제2 돌기(311) 외면을 압박하여 제2 돌기(311)가 댐퍼의 구동축과 압박 결합하게 되고, 하부 플렌지(320)의 직경이 넓어지며 하부 플렌지(320)의 외면이 섹션기어(240)의 회전축(241) 내면을 압박하여, 섹션기어(240)에 하부 플렌지(320)가 고정되는 것이다.That is, when narrowing the vertical distance between the first protrusion 321 and the second protrusion 311 by using the clamping bolt 330, the inner surface 323 of the lower flange 320 having a tapered structure The second protrusion 311 is pressed against the outer surface of the second flange 311 of the upper flange 310 to be coupled to the driving shaft of the damper, the diameter of the lower flange 320 is widened and the lower flange 320 of the The outer surface presses the inner surface of the rotation shaft 241 of the section gear 240, so that the lower flange 320 is fixed to the section gear 240.
아울러, 본 발명인 댐퍼 작동기는 상기 회전축(221)의 상측 단부가 마주보는 상기 외부 하우징(400)의 내면과 이격 배치되며, 상기 회전축(221)의 상측 단부에 센서용 자석(221-1)이 위치되고, 상기 외부 하우징(400)의 내면에 상기 센서용 자석(221-1)에 대응하는 GMR 센서(411)가 구비되어, 상기 브러쉬리스 모터(110)에서 전달된 회전력으로 회전하는 상기 구동 출력부(300)의 회전 변위 및 속도를 제어할 수 있다.In addition, the damper actuator of the present invention is disposed spaced apart from the inner surface of the outer housing 400 facing the upper end of the rotary shaft 221, the sensor magnet 221-1 is located at the upper end of the rotary shaft 221 And a GMR sensor 411 corresponding to the sensor magnet 221-1 on the inner surface of the outer housing 400, and the drive output unit rotating with the rotational force transmitted from the brushless motor 110. The rotational displacement and speed of 300 can be controlled.
상세히 설명하면, 댐퍼를 작동시키기 위해 브러쉬리스 모터(110)에서 생산되는 동력은 회전 토크를 향상시키기 위해 유성기어장치(120)와 다양한 기어(210, 220, 230, 240)를 통해 상기 구동 출력부(300)로 전해지며 감속된다.In detail, the power produced by the brushless motor 110 to operate the damper is driven through the planetary gear device 120 and various gears 210, 220, 230, and 240 to improve rotational torque.
