본 고안은 20ton 미만의 소형 선박에 장착되는 고속 엔진용 다관식 유압 감속 클러치 장치에 관한 것으로 특히, 전, 후진 디스크 드럼을 입력축과 출력축에 각각 분리하여 설치함으로서 후진시 후진 디스크 드럼에는 이미 감속된 상태로 압이 걸릴 수 있도록 하여 마찰판간의 마찰력 감소로 수명 연장과 기계적 효율을 증진시킬 수 있도록 한 것이다.The present invention relates to a multi-pipe hydraulic deceleration clutch device for a high speed engine mounted on a small vessel of less than 20 tons, and in particular, the front and reverse disc drums are separately installed on the input shaft and the output shaft, so that the reverse disk drum is already decelerated. It is designed to increase the life and mechanical efficiency by reducing the friction between friction plates.
주지하는바와 같이 클러치는 엔진의 구동축과 출력측 사이에서 동력을 연결 또는 단절시키기 위한 장치인바, 종래의 유압식 다판 클러치에 있어서는 제 1 도에서 도시한바와 같다.As is well known, the clutch is a device for connecting or disconnecting power between the drive shaft and the output side of the engine. In the conventional hydraulic multi-plate clutch, as shown in FIG.
몸체(1)에 설치된 입력축(2)에 공회전 하도록 끼워진 전, 후진 기어(4a, 4b)의 내측으로 각각 마찰판(5a, 5b)이 설치되어 입력축(2)의 마찰판(5a', 5b')과 긴밀한 간격을 유지하고 있으며, 입력축(2)의 몸체(1) 외면에 설치된 유압펌프(H)가 제어장치(C)의 조작에 의해 전, 후진 피스톤(F. P)(B.P)을 선택적으로 작동시켜 마찰판(5a, 5a', 5b, 5b')을 가압, 입력축(2)의 회전력을 전, 후진 기어(4a, 4b)에 전달하게 된다.The friction plates 5a and 5b are respectively installed inside the front and rear gears 4a and 4b, which are fitted to idle on the input shaft 2 installed on the body 1, so that the friction plates 5a 'and 5b' of the input shaft 2 and Closely spaced, the hydraulic pump (H) installed on the outer surface of the body (1) of the input shaft (2) selectively operates the forward and backward piston (F. P) (BP) by the operation of the control device (C) By pressing the friction plates 5a, 5a ', 5b and 5b', the rotational force of the input shaft 2 is transmitted to the forward and reverse gears 4a and 4b.
출력축(3)에 고정된 전진 감속기어(6a)는 전진기어(4a)와 후진 감속기어(6b)는 아이들기어(7)에 의해 후진기어(4b)와 맞물려 전, 후진기어(4a, 4b)의 회전력을 출력축에 전달하여 정, 역회전 시키도록 구성되어 있다.The forward reduction gear 6a fixed to the output shaft 3 has the forward gear 4a and the reverse reduction gear 6b engaged with the reverse gear 4b by the idle gear 7, and the forward and reverse gears 4a, 4b. It is configured to transmit the rotational force of to the output shaft to rotate forward and reverse
이상의 구성에서 보듯이 종래의 구성에 있어서는 전, 후진용 마찰판들이 모두 입력축에 설치되어 있기 때문에 전진하다가 후진할 경우 고속 회전하는 엔진으로 부터의 입력축 회전력이 유압에 의하여 밀착되는 마찰판들에 그대로 걸리게 되므로 디스크 마찰열로 인한 기계 자체의 고온 현상이 발생하게 되며 이로 인하여 윤활유의 유막 형상이 제대로 이루어지지 않아 내부부품(오링, 고무링,...등)의 수명을 단축시킬뿐 아니라 마찰판의 마모율이 극심하여 당초의 셋링폭으로 유지가 곤란하므로 스립 현상이 발생하여 수시 조정이 필요하게 되고 고가인 마찰판을 수시 교체하여 주어야만 하였으며 마찰이 많기 때문에 마찰 동력이 커짐으로 동력 손실이커서 연료비가 증가되는등 여러 가지의 문제점이 있었다.As shown in the above configuration, in the conventional configuration, since both forward and backward friction plates are installed on the input shaft, when the drive is moved forward and backward, the input shaft rotational force from the high-speed rotating engine is applied to the friction plates that are in close contact with the hydraulic disk. The high temperature phenomenon of the machine itself is caused by the heat of friction, and as a result, the oil film of the lubricating oil is not properly formed, which not only shortens the life of internal parts (O-ring, rubber ring, ...) but also the wear rate of the friction plate is extremely high. Because it is difficult to maintain the set width of, it is necessary to adjust it at any time because slip phenomenon occurs and expensive friction plate has to be replaced at any time.There are various problems such as fuel cost increase due to large power loss due to the high frictional power due to the high friction. There was this.
또한, 종래의 다른 방식으로서 제 2 도에서 도시한 바와 같이 입력축(11)에 고정 부착된 전진 클러치(14)와 공회전축(13)에 고정 부착된 후진클러치(15)의 외주에 각각 치차(22, 23)를 형성함과 아울러 이들 치차(22, 23)를 상호 치차 연결시켜서 각각의 전, 후진 클러치(14, 15)를 선택적으로 작동시키는 것에 의해 입력축(11)의 동력이 전진 구동기어(16) 또는 후진 구동기어(17)로 전달되도록 한 것 (공개 실용신안공보, 공개번호 88-4768)이 안출된바 있으나, 이 역시 전진 클러치와 후진 클러치가 분리되기는 하였지만 회전비는 마찬가지여서 상기의 문제점을 근본적으로 해결할 수 있는 방편이 되지 못하였다.As another conventional method, as shown in FIG. 2, the teeth 22 are fixed to the outer peripheries of the forward clutch 14 fixedly attached to the input shaft 11 and the reverse clutch 15 fixedly attached to the idle shaft 13, respectively. And 23, and the gears 22 and 23 are connected to each other to selectively operate the respective forward and reverse clutches 14 and 15 to drive the power of the input shaft 11 to the forward drive gear 16. ) Or the transmission to the reverse drive gear 17 (Public Utility Model Publication, Publication No. 88-4768) has been devised, but this is also the forward clutch and the reverse clutch, but the rotation ratio is the same, so the above problems are solved. It was not a fundamental solution.
본 고안은 이와 같은 제결점을 해결하기 위하여 전진 디스크 드럼을 입력축에 후진 디스크 드럼을 출력측에 각각 분리하여 설치함으로서 후진시 감속되어 구동되는 출력축에서 후진디스크드럼이 작동될 수 있게하여 마찰판간의 마찰력을 감소시켜 수명 연장과 더불어 기계적 효율을 증진시킬 수 있도록 안출한 것으로 이를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.In order to solve the above problems, the present invention separates the forward disk drum from the input shaft and installs the reverse disk drum on the output side so that the reverse disk drum can be operated on the output shaft driven by deceleration during the reverse motion, thereby reducing the friction force between the friction plates. In order to improve the mechanical efficiency as well as to extend the service life to be described in detail by the accompanying drawings as follows.
제 3 도는 본 고안의 전체 구성 단면도이다.3 is a cross-sectional view of the overall configuration of the present invention.
몸체(31)의 상하에는 입력축(32)과 출력축(33)을 설치하며, 몸체내에서의 입력축과 출력축간의 좌측에는 전진기어(34)와 전진 감속기어(35)를 치합상태로 고정설치하고, 우측에는 아이들기어(38)를 사이에 두고 후진기어(36)와 후진 감속기어(37)을 치합 상태로 고정 설치한다.An input shaft 32 and an output shaft 33 are installed above and below the body 31, and the forward gear 34 and the forward reduction gear 35 are fixed to the left side between the input shaft and the output shaft in the body, The reverse gear 36 and the reverse reduction gear 37 are fixedly installed in the engaged state with the idle gear 38 interposed therebetween.
이들 양전, 후진 기어와 전, 후진 감속기어들간 사이의 축선상에는 전진용 디스크드럼(39)과 후진용 디스크드럼(40)이 설치되는데 이들에 유압을 공급할 수 있도록 입, 출력측(32, 33)내에는 유압통로공(41, 42)이 각각 형성된다.A forward disc drum 39 and a reverse disc drum 40 are provided on the axis between the positive and reverse gears and the forward and reverse gears, and are provided in the input and output sides 32 and 33 to supply hydraulic pressure thereto. The hydraulic passage holes 41 and 42 are respectively formed.
이때 양 디스크 드럼의 설치에 있어서는 각 내주면에 스플라이홈을 갖는 전진용 디스크 드럼(39)은 전진기어(34)에 후진용 디스크드럼(40)은 후진 감속기어(37)에 상호 반대 방향을 향하도록 고정 설치하고, 양 드럼의 내부 길이에 해당하는 전, 후진 축선상에는 스플라인축을 형성한 다음, 스플라인측과 스플라인홈에 각각 맞추어 수개의 마찰판(43a, 43b, 43a', 43b')을 순차 교대 삽입 내장시킨후 최종 밀판(44a, 44b)을 삽입 설치시킨다.In this case, in the installation of both disk drums, the forward disk drum 39 having the spline groove on each inner circumferential surface is directed to the forward gear 34, and the reverse disk drum 40 is opposite to the reverse reduction gear 37. The spline shaft is formed on the forward and reverse axis corresponding to the inner length of both drums, and then several friction plates 43a, 43b, 43a ', and 43b' are sequentially inserted in accordance with the spline side and the spline groove, respectively. After built-in, the final mill plates 44a and 44b are inserted and installed.
한편, 이들을 밀어 밀착 작동시키게 되는 유압 실린더를 양편에 설치하되, 전진 유압실린더(45)는 별도 형성하여 내부에 리턴 판스프링(46)이 끼워지고 전진피스톤(47)이 삽입되는 상태로 전진축에 삽입 설치하며, 후진 유압실린더(48)는 전진 감속기어(35)의 일측면에 요입 형성한후 이에 후진 피스톤(49)을 삽입하고 외측에서 리턴판스프링(50)으로 탄력 지지시켜 조립 구성된 것이다.On the other hand, the hydraulic cylinder to push them in close contact with each other, but the forward hydraulic cylinder 45 is formed separately, the return plate spring 46 is fitted therein and the forward piston 47 is inserted into the forward shaft Insertion and installation, the reverse hydraulic cylinder 48 is formed by indentation in one side of the forward reduction gear 35 is inserted into the reverse piston 49 and elastically supported by the return plate spring 50 from the outside is assembled.
도면중 미설명부호 51는 유압 제어장치. 52는 유압 펌프이다.In the drawings, reference numeral 51 denotes a hydraulic control device. 52 is a hydraulic pump.
이와 같이 구성된 본 고안은 제 3 도에서 도시한 바와 같이 유압제어장치(51)의 조작레버는 통상 전진-중립-후진으로 조작되도록 되어 있는바, 배를 전진시키고져 할 시 조작 레버를 전진 위치에 놓게 되면 입력축(32)의 유압통통공(41)을 통하여 유압이 전진 유압실린더(45)로 유입되어 전진피스톤(46)을 밀게됨으로 전진용 디스크드럼(39)내의 마찰판(43a, 43b)들이 밀착되어 등력이 전진 감속기어(35)로 전달되므로 출력축(33)은 감속전진 회전 구동된다.In the present invention, as shown in FIG. 3, the operating lever of the hydraulic control device 51 is normally operated in the forward-neutral-reverse direction. When the ship is advanced, the operation lever is moved to the forward position. When placed, the hydraulic pressure flows into the forward hydraulic cylinder 45 through the hydraulic through hole 41 of the input shaft 32 to push the forward piston 46, so that the friction plates 43a and 43b in the forward disk drum 39 are in close contact with each other. Since the equal force is transmitted to the forward reduction gear 35, the output shaft 33 is driven to decelerate forward rotation.
이때, 후진용 디스크 드럼(40)은 작동되지 않고 있는 상태이므로 후진 감속기어(37)와 아이들기어(38) 및 후진기어(36)는 공회전 상태가 된다.At this time, since the reverse disk drum 40 is not operating, the reverse reduction gear 37, the idle gear 38, and the reverse gear 36 are in an idle state.
이와 같은 상태로 전진하다가 후진을 위하여 유압 제어장치(51)의 조작 레버를 후진 위치로 당겨 놓게 되면 전진 유압 실린더(45)에 압을 가하고 있던 유압은 빠져 나가게 되고 전진피스톤(47)이 리턴 판스프링(46)에 의하여 복귀되므로 전진용 디스크 드럼(39)내의 마찰판(43a, 43b)들은 상호 이격된다.In this state, when the operation lever of the hydraulic control device 51 is pulled to the retracted position for reversing, the hydraulic pressure applied to the forward hydraulic cylinder 45 is released and the forward piston 47 returns to the return leaf spring. By returning by 46, the friction plates 43a and 43b in the advancing disc drum 39 are spaced apart from each other.
이와 동시에 유압이 출력측(33)의 유압 통로공(42)을 통하여 전진 감속기어(35)에 형성된 후진 유압실린더(48)로 유입되어 후진피스톤(49)을 밀게됨으로 후진용 디스크드럼(40)내의 마찰판(43a', 43b')들이 밀착되어 동력이 후진기어(36)와 아이들기어(38) 및 후진 감속기어(37)로 전달되므로 출력축(33)은 감속 후진 회전 구동된다.At the same time, the hydraulic pressure flows into the reverse hydraulic cylinder 48 formed in the forward reduction gear 35 through the hydraulic passage hole 42 on the output side 33 and pushes the reverse piston 49 so that the reverse disk drum 40 Since the friction plates 43a 'and 43b' are in close contact with each other, power is transmitted to the reverse gear 36, the idle gear 38, and the reverse reduction gear 37, so that the output shaft 33 is driven to decelerate backward rotation.
이때는 전진용 디스크드럼(39)이 작동되지 않고 있는 상태이므로 전진 감속기어(35)와 전진기어(34)는 공회전 상태가 된다.At this time, since the forward disk drum 39 is not operating, the forward reduction gear 35 and the forward gear 34 are in an idle state.
다시 전진시는 후진 유압실린더(48)에 압을 가하고 있던 유압은 빠져 나가게 되고 후진피스톤(49)이 리턴판스프링(50)에 의하여 복귀되므로 후진용 디스크 드럼(40)내의 마찰판(43a, 43b')들은 상호 이격되어 최초 상태로 된다.Again, the hydraulic pressure that applied the reverse hydraulic cylinder 48 at the time of the forward movement is released and the reverse piston 49 is returned by the return plate spring 50, so that the friction plates 43a and 43b 'in the reverse disc drum 40 are retracted. ) Are spaced apart from one another in the initial state.
이와같이 동작되는 본 고안은 후진용 디스크드럼이 출력축에 설치되어 있으므로 후진 유압 작동기 마찰판 상호간 접촉이 감속되어진 상태에서 이루어지게 되므로 마찰판간의 마찰력 감소로 열이 발생되지 않게 되어 유막 형성이 원활하고 내부 부품 및 마찰판의 수명을 연장할 수 있게 된다.In this way, this design works because the reversing disk drum is installed on the output shaft, so that the contact between the reverse hydraulic actuator friction plates is decelerated, so heat is not generated due to the reduction of friction between the friction plates. It is possible to extend the life of the.
따라서, 마찰판 셋링폭을 수시 조정하여야 하였던 번거로움을 해소할 수 있게 되었으며 슬립 현상이 발생되지 않게 되어 동력 손실이 적고 연료비를 절감할 수 있게 되는 효과가 있으며 후진 유압 실린더를 전진 감속기어에 형상함으로서 콤펙트하게 구성할 수 있게 되는 등의 유용한 효과가 있다.Therefore, it is possible to solve the trouble of having to adjust the friction plate setting width at any time, and the slip phenomenon does not occur, thereby reducing the power loss and reducing fuel costs, and by forming the reverse hydraulic cylinder on the forward reduction gear, it is compact. There is a useful effect such as being able to configure.
