해수윤활식 선미관{Stern tube}Seawater Lubrication Stern Tube {Stern tube}

본 고안은 해수윤활식 선미관에 관한 것으로 보다 상세하게는 선미관 본체와The present invention relates to a seawater lubricated stern tube, and more specifically,

; 상기 본체의 내부에 삽입되어 설치되며 엔진의 구동 모터에 연결되어 있는 구동샤프트와; 상기 구동샤프트의 외주부면에 부착되며 엔진 내부로 해수의 유입을 방지하는 지면재 및 초산스폰지 패킹과; 상기 지면재를 고정시키는 고정수단 및 상기 초산스펀지 패킹을 압착하는 패킹글랜드를 포함하여 구성되는 것을 특징으로 하는 해수윤활식 선미관.; A drive shaft inserted into the main body and connected to a drive motor of the engine; Ground material and acetic acid sponge packing attached to an outer circumferential surface of the drive shaft to prevent inflow of seawater into the engine; A seawater lubricating stern tube, comprising: a fixing means for fixing the ground material and a packing gland for pressing the acetic acid sponge packing.

일반적으로 사용되는 해수윤활식 선미관은 도 1에 도시된 바와 같이 구동 샤프트는 선미관본체(100)를 관통하여 배치되어 있다. 선미관본체(100)의 내부공간에는 구동 샤프트(10)는 지지하는 부싱(120)이 설치되며,구동샤프트(10)와 부싱(120)사이에는 지면재(20)로써 탄성을 지닌 고무재가 설치되고, 상기 지면재(20)을 잡아주는 멈춤쇠(40)가 설치된다.In general, a seawater lubricated stern tube is used as shown in FIG. 1, and a driving shaft is disposed through the stern tube body 100. A bushing 120 for supporting the drive shaft 10 is installed in the inner space of the stern tube body 100, and a rubber material having elasticity as the ground material 20 is installed between the drive shaft 10 and the bushing 120. And, the detent 40 for holding the ground material 20 is installed.

상기 선미관본체(100)는 선체구조와 격벽에 연결되어 설치되며, 선미관본체The stern tube body 100 is installed connected to the hull structure and the bulkhead, the stern tube body

(100) 후미부에 설치된 부싱(120)후부에는 구동샤프트(10)와 선미관본체(100)와 수밀하기 위해 구리스-실패킹(30)이 설치되는데 상기 구리스-실패킹(30)은 구동 샤프트(10)가 회전시 구리스-실패킹(30)이 마모되어 기관실에 바닷물이 유입되면(100) The rear of the bushing (120) installed in the rear portion is provided with a grease-sealing (30) for sealing with the drive shaft 10 and the stern tube body 100, the grease-sealing (30) is a drive shaft When (10) rotates grease-sealing (30) is worn and the seawater flows into the engine room

선미관본체(100)와 연결된 패킹글랜드(200)의 조절볼트(210)로 조여주면 압착프레임(220)이 좌우로 움직여 구리스-실패킹(30)을 압착시키며 선미관본체(100)와 구동샤프트(10)를 수밀해 준다.When tightened with the adjustment bolt 210 of the packing gland 200 connected to the stern tube body 100, the pressing frame 220 is moved to the left and right to compress the grease seal packing 30, driving with the stern tube body 100 The shaft 10 is watertight.

이러한 종래의 구동 샤프트를 수밀하기 위하여 사용되는 구리스-실패킹은 구동 샤프트가 회전시 구리스-실패킹과 접촉하는 구동 샤프트의 측면이 마모가 심하여 엔진의 출력을 저하시키며, 구동 샤프트의 마모된 틈으로 바닷물이 기관실로 유입을 막기 위해 구리스-실패킹을 압착하는 패킹글랜드를 수시로 조절해야 되는 문제점이 있다.The grease-sealing used for watertighting such a conventional drive shaft causes severe wear on the side of the drive shaft, which contacts the grease-sealing when the drive shaft rotates, thereby lowering the engine's power and causing a worn gap in the drive shaft. In order to prevent the inflow of seawater into the engine room, there is a problem in that the packing gland which compresses the grease-sealing packing is often adjusted.

본 고안은 상기한 문제점을 해소시키기 위하여 안출한 것으로서, 구동 샤프트와 선미관본체가 수밀하기 위해 설치되는 패킹의 수명을 연장하며, 구동샤프트와 패킹이 접촉하는 구동 샤프트의 접촉면이 마모되는 손실수가 적어 엔진의 출력이 저하되지 않도록 하며, 마모의 손실수가 적어 패킹글랜드의 사용빈도를 줄일 수 있는 해수윤활식 선미관을 제공하는데 있다.The present invention has been devised to solve the above problems, extends the life of the packing is installed for the water shaft and the stern tube body is watertight, and the number of losses that the contact surface of the drive shaft and the drive shaft contacting the packing wears less It is to provide a seawater lubricated stern tube that reduces the output of the engine and reduces the frequency of use of the packing gland due to the low loss of wear.

제 1도는 종래의 해수윤활식 선미관의 단면도.1 is a cross-sectional view of a conventional seawater lubricated stern tube.

제 2도는 본 고안의 따른 해수윤활식 선미관의 단면도.2 is a cross-sectional view of the seawater lubricated stern tube according to the present invention.

상기와 같은 목적을 달성하기 위한 본 고안은 선미관 본체와; 상기 본체의 내부에 삽입되어 설치되며 엔진의 구동 모터에 연결되어 있는 구동샤프트와; 상기 구동샤프트의 외주부면에 부착되며 엔진 내부로 해수의 유입을 방지하는 지면재 및 초산스폰지 패킹과; 상기 지면재를 고정시키는 고정수단 및 상기 초산스펀지 패킹을 압착하는 패킹글랜드를 포함하여 구성되는 것을 특징으로 하는 해수윤활식 선미관에 의하여 달성된다.The present invention for achieving the above object is the stern tube body; A drive shaft inserted into the main body and connected to a drive motor of the engine; Ground material and acetic acid sponge packing attached to an outer circumferential surface of the drive shaft to prevent inflow of seawater into the engine; It is achieved by a seawater lubricating stern tube comprising a fixing means for fixing the ground material and a packing gland for pressing the acetic acid sponge packing.

이하 본 고안의 바람직한 실시예를 첨부된 도면을 참조하여 설명한다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

도 2는 본 고안의 따른 해수윤활식 선미관의 단면도이다.2 is a cross-sectional view of the seawater lubricated stern tube according to the present invention.

도시한 바와 같이 본 고안에 따른 해수윤활식 선미관를 상세히 살펴보면,선미관본체(100)의 내부에 삽입되어 설치되며 엔진의 구동 모터에 연결되어 있는 구동샤프트(10)가 설치되고, 선미관본체(100)의 내부공간에는 구동 샤프트(10)는 지지하는 부싱(120)이 설치되며, 구동샤프트(10)와 부싱(120)사이에는 지면재(20)로써 탄성을 지닌 고무재가 설치되고, 상기 지면재(20)을 잡아주는 멈춤쇠(40)가 설치된다Looking at the seawater lubricated stern tube according to the present invention in detail as shown, the drive shaft 10 is inserted into the stern tube body 100 is installed and connected to the drive motor of the engine is installed, the stern tube body 100 In the inner space of the drive shaft 10 is provided with a bushing 120 for supporting, between the drive shaft 10 and the bushing 120 is provided with a rubber material having elasticity as the ground material 20, the ground material Detent 40 to hold 20 is installed

상기 선미관본체(100)는 선체구조와 격벽에 연결되어 설치되며,선미관본체The stern tube body 100 is installed connected to the hull structure and the bulkhead, the stern tube body

(100) 후미부에 설치된 부싱(120)후부에는 구동샤프트(10)와 선미관본체(100)와 수밀하기 위해 초산스펀지패킹(50)이 설치되는데 구동 샤프트(10)가 회전시 초산스펀지(50)가 마모되어 기관실에 바닷물이 유입되면 선미관본체(100)와 연결된 패킹글랜드(200)의 조절볼트(210)로 조여주면 압착프레임(220)이 좌우로 움직이도록 설치된다.An acetic acid sponge packing 50 is installed at the rear of the bushing 120 installed at the rear end to seal the driving shaft 10 and the stern tube body 100 with the acetic acid sponge 50 when the driving shaft 10 rotates. ) When worn and the seawater flows into the engine room, tighten the control bolt 210 of the packing gland 200 connected to the stern tube body 100 is installed so that the pressing frame 220 moves to the left and right.

상기와 같이 구조로 이루어진 본 고안의 작용은 다음과 같다.The operation of the present invention made of a structure as described above is as follows.

상기 선미관본체(100)와 수밀하기 위해 초산스펀지패킹(50)이 설치되는데 구동 샤프트(10)가 회전시 초산스펀지(50)와 접촉되는 부분이 마모되어 기관실에 바닷물이 유입되면 선미관본체(100)와 연결된 패킹글랜드(200)의 조절볼트(210)로 조여주면 압착프레임(220)이 좌우로 움직이며 압착시켜 기관실로 바닷물이 유입되는 것을 막는다. 이러한 바닷물이 기관실로 유입되는 것을 방지하기 위해 일반적으로 사용되는 구리스-실패킹(30)보다 성능이 뛰어난 초산스펀지패킹(50)은 친수성이 강하며, 이는 분자내의 친수기인 OH기를 보유하고 연속 다공구조로 흡입율,탄력성, 인장강도와 내 마모성이 우수하여 패킹, 구동샤프트의 수명연장 및 사용자가 패킹글랜드를 수시로 조작하지 안해도 된다.The acetic acid sponge packing 50 is installed to be watertight with the stern tube body 100. When the drive shaft 10 rotates, the part contacted with the acetic acid sponge 50 is worn, and when the seawater flows into the engine room, the stern tube body ( Tighten to the control bolt 210 of the packing gland 200 connected to 100 and the pressing frame 220 is moved to the left and right to prevent the sea water from flowing into the engine room. Acetic acid sponge packing (50), which is superior to grease-sealing (30), which is generally used to prevent the introduction of sea water into the engine room, has a high hydrophilic property. Furnace suction rate, elasticity, tensile strength and abrasion resistance are excellent, so the life of packing and drive shaft can be extended and users do not have to operate packing gland at any time.

이와 같이 구성된 본 고안은 선미관 본체와 구동 샤프트 외측부에 설치되는 초산스폰지 패킹은 구동 샤프트가 회전시 패킹과 접촉되는 부분이 마모되는 손실수가 적어 패킹글랜드을 수시로 조작하지 않아도 되며, 패킹과 구동샤프트의 수명이 길고, 마모성으로 인하여 엔진의 힘이 저하되는 것을 방지하는 효과가 있다.The present invention configured as described above has the acetic acid sponge packing installed in the stern tube body and the drive shaft outside, so that the part where the drive shaft is in contact with the packing is worn out, so there is no need to operate the packing gland from time to time. Long life, and there is an effect of preventing the power of the engine is lowered due to wear.
