하지만 이와 같은 종래 볼트와 너트를 이용하여 선박의 주기관 대형엔진에 터닝기어를 조립시 엔진구조상 협소한 공간에서 파워 렌치를 사용하여 조임작업을 함으로서 정확한 조임량 준수가 힘들어 터닝기어가 불안전 조립되어, 터닝기어 밀림이 발생하여 엔진 또는 터닝기어 작동이 볼트와 너트가 풀릴 수 있어 안전 사고 위험이 있다. However, when assembling the turning gear to the large engine of the ship's main engine by using such a conventional bolt and nut, the tightening operation is performed by using a power wrench in a narrow space due to the engine structure, and it is difficult to observe the exact tightening amount of the turning gear. Turning gears can cause the engine or turning gears to loosen bolts and nuts, which creates a safety hazard.

1 is an exemplary view showing a state in which a turning gear is assembled to a main engine by using the device of the present invention, and FIG. 2 is a main gear of the turning gear of the device of the present invention. It is an example picture showing a state assembled to the engine, Figure 3 is a picture showing a hydraulically tightening application example using the stud bolt (Stud Bolt) and the hydraulic nut (nut) constituting the present invention.
도시된 바와 같이 본 고안에 따른 터닝기어(Turning gear, 1)는 대형 디젤엔진 중간부에 설치되어 대형엔진을 구동력을 전달하는 크랭크축 끝단에 설치된 크랭크축기어에 피니언기어(4)가 물리도록 설치되고, 이 피니언기어(4)는 터닝기어에 구비된 모터(3)에 의해 회전토록 구성된다. 이와 같이 구성함으로써 크랭크축기어와 연결된 크랭크축을 회전시켜 원하는 실린더를 원하는 위치에 맞추고, 정박 중 엔진내부에 지속적으로 윤활유를 공급하기 위한 크랭크축을 저속 회전시키게 된다.
Turning gear (Turning gear, 1) according to the present invention is installed in the middle of a large diesel engine is installed so that the pinion gear (4) is fitted to the crankshaft gear installed at the end of the crankshaft for transmitting the driving force to the large engine. The
따라서 정밀한 터닝기어가 작동하기 위해서는 크랭크축 기어와 맞물린 피니언기어간의 결합이 정밀해야만 하는데, 이와 같은 정밀한 기어 맞물림을 위해서는 터닝기어(Turning gear, 1)와 대형 디젤엔진간의 체결이 견고해야 한다. 즉, 터닝기어가 장치되는 대형 디젤엔진간의 체결을 위한 조립수단이 정확한 토크(Torque) 조임량이 준수되게 완전 조립되어야 한다. 이와 같이 정확한 조임량을 가지게 완전 조립되면 터닝기어 밀림이 발생하지 않아 엔진 또는 터닝기어 작동시 원활하게 된다.Therefore, in order for the precise turning gear to operate, the engagement between the crankshaft gear and the engaged pinion gear must be precise. For such precise gear engagement, the turning gear (1) and the large diesel engine must be firmly connected. In other words, the assembly means for fastening between large diesel engines equipped with turning gears must be fully assembled so that the correct torque tightening amount is observed. As such, when fully assembled with the correct amount of tightening, the turning gear does not occur and the engine or the turning gear operates smoothly.
이를 위해 본 고안은 터닝기어를 메인엔진(Main engine) 상부에 조립시 정확한 조임량을 가지게 유압 조립수단을 구비하고 있다.To this end, the present invention is equipped with a hydraulic assembly means to have a precise tightening amount when assembling the turning gear on the main engine (Main engine).
유압조립수단은 터닝기어의 프레임하부와 메인엔진(Main engine)의 프레임 상부간을 관통하는 스터드 볼트(Stud bolt, 5)와; 메인엔진(Main engine)의 프레임을 정확한 필요 조임량을 제공하는 유압 너트(Hydraulic nut, 6)로 구성된다. 여기서 유압 너트(Hydraulic nut, 6)의 구체적인 구성은 상용의 장치를 사용하면 되므로 구체적인 구성 설명은 생략한다.Hydraulic assembly means includes a stud bolt (5) passing through the lower frame of the turning gear and the upper frame of the main engine (Stud bolt); The frame of the main engine consists of a hydraulic nut (6) which provides the exact required amount of tightening. Here, the specific configuration of the hydraulic nut (Hydraulic nut, 6) may use a commercially available device, so a detailed description of the configuration is omitted.
작동방법은 유압 너트 둘레에 도 1에 도시된 것과 같은 유압잭을 장치하여 유압제공에 의해 스터드 볼트(Stud bolt, 5)를 필요로 하는 조임량 만큼 당겨준 후, 스터드볼트에 대한 위치 고정력을 제공함으로써 견고하게 필요 조임량에 해당하는 위치에서 유압 너트가 스터드 볼트(Stud bolt, 5)를 정확한 필요 조임량에 의해 체결하게 된다.The operating method is to install a hydraulic jack as shown in Figure 1 around the hydraulic nut by pulling the required amount of tightening the stud bolt (Stud bolt, 5) by providing a hydraulic pressure, and then providing a position fixing force to the stud bolt At the position corresponding to the required tightening amount, the hydraulic nut tightens the
상기 스터드 볼트(Stud bolt, 5)와 터닝기어의 프레임 하부간 그리고 메인엔진(Main engine)의 프레임과 유압 너트(6)간에는 간극재(Distance piece; 7, 8)가 위치하여 조임력을 증진시키게 구성된다.A
또한 터닝기어의 프레임에는 측방향으로 스터드 볼트(Stud bolt, 5)의 고정지지하기 위한 육각볼트(Hex. bolt, 10) 및 너트(Nut, 11)가 체결되어 보다 견고한 체결을 돕게 구성되어 있다.
In addition, the hexagonal bolt (Hex. Bolt, 10) and the nut (Nut, 11) for fastening and supporting the stud bolt (5) in the side of the turning gear frame is configured to help more secure fastening.
본 고안은 상술한 특정의 바람직한 실시 예에 한정되지 아니하며, 청구범위에서 청구하는 본 고안의 요지를 벗어남이 없이 당해 고안이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형실시가 가능한 것은 물론이고, 그와 같은 변경은 청구범위 기재의 범위 내에 있게 된다.
