Description
본 고안은 중장비의 엔진 냉각팬 설치구조에 관한 것으로, 특히 엔진의 몸체에 분리설치된 별치식 냉각팬 설치구조에 관한 것이다.The present invention relates to an engine cooling fan installation structure of heavy equipment, and in particular to a separate cooling fan installation structure separately installed on the engine body.
중장비의 엔진에는 엔진의 과열을 방지하기 위한 냉각팬이 부착설치되어 있다. 이 냉각팬은 엔진의 구동력으로 회전하면서 그 앞쪽에 배치된 라디에이터에 송풍하여 냉각수를 냉각시킨다.Heavy engines are equipped with cooling fans to prevent engine overheating. The cooling fan blows to a radiator arranged in front of the engine while rotating with the driving force of the engine to cool the cooling water.
상기 냉각팬(20)은, 일반적으로 도 2에 도시된 바와 같이,엔진의 냉각수펌프축 선단과 직접 연결되되, 팬 스페이서(21)를 매개로 엔진블록(E)의 전면과 일정한 거리를 두고 설치되어 있다. 그리고 상기 냉각수펌프축에는 팬 구동풀리(22)가 설치되어 엔진의 크랭크축에 설치된 풀리(24)와 팬벨트(25)로 연결되어 있다. 따라서 엔진이 가동되면 팬(20)이 엔진의 크랭크축과 함께 회전하면서 그 앞쪽에 설치된 라디에이터(도시안됨)쪽으로 송풍하여 그 라디에이터를 통과하는 냉각수를 냉각시키게 되는 것이다.As shown in FIG. 2, the cooling fan 20 is directly connected to the front end of the cooling water pump shaft of the engine, and installed at a predetermined distance from the front surface of the engine block E via the fan spacer 21. It is. In addition, a fan drive pulley 22 is installed at the coolant pump shaft, and is connected to the pulley 24 and the fan belt 25 installed on the crank shaft of the engine. Therefore, when the engine is running, the fan 20 rotates with the engine's crankshaft and blows toward the radiator (not shown) installed in front of the engine to cool the coolant passing through the radiator.
그런데 상기 냉각팬(20)은 엔진의 크기가 커짐에 따라 그 크기도 함께 커져야 냉각효율을 높일 수 있는 데, 팬의 크기가 커지면 그 팬을 지지하는 베어링이나 그 팬을 회전연동시키는 기어등 다른 부품에 가해지는 부하도 증가되어 이들 부품의 수명을 단축시키는 문제가 있었다.By the way, as the size of the engine increases, the cooling fan 20 must also increase in size to increase the cooling efficiency. As the size of the fan increases, the bearing supporting the fan or the gear for rotating and interlocking the fan is increased. There is also a problem that the load on the load is increased to shorten the life of these parts.
이에 본 고안은 상기와 같은 종래 냉각팬 설치구조가 가진 문제점을 해소하기 위해 안출된 것으로, 엔진의 크기에 따라 냉각팬의 크기를 자유로이 변경할 수 있고, 고장이 나더라도 쉽게 교체수리할 수 있도록 된 냉각팬 설치구조를 제공함에 목적이 있다.The present invention has been devised to solve the problems of the conventional cooling fan installation structure as described above, the cooling fan can be freely changed the size of the cooling fan according to the size of the engine, the cooling can be easily replaced and repaired even if a failure The purpose is to provide a fan mounting structure.
상기 목적을 달성하기 위한 본 고안은, 엔진블록에 일측에 브라켓트가 부설되고, 이 브라켓트에 플레이트가 엔진블록 전면부를 향하여 대략 수직되게 연장설치되며, 상기 플레이트에는 냉각팬이 팬스페이서를 매개로 회전가능하게 설치되고, 상기 팬스페이서에는 팬구동용 풀리가 고정설치되어 엔진 크랭크축상에 설치된 풀리와 벨트로 연결된 구조로 되어 있다.The present invention for achieving the above object, a bracket is attached to one side of the engine block, the plate is installed on the bracket is installed to extend substantially vertically toward the front of the engine block, the cooling fan is rotatable through the fan spacer The fan spacer is fixedly installed, and has a structure in which the pulley and the belt are installed on the engine crankshaft.

이하 본 고안에 따른 냉각팬 설치구조의 실시예를 첨부된 도면에 따라 상세히 설명한다.Hereinafter, an embodiment of a cooling fan installation structure according to the present invention will be described in detail with reference to the accompanying drawings.
도 1에 도시된 바와 같이, 엔진블록(E)의 앞쪽에는 플레이트(11)가 그 엔진블록(E)과 대략 평행하게 배치되어 엔진블록(E)에서 연장된 브라켓트(10)를 매개로 부설되고, 이 플레이트(11)상에는 냉각팬(12)이 팬스페이서(13)를 매개로 회전가능하게 설치되어 있다.As shown in FIG. 1, in front of the engine block E, a plate 11 is disposed substantially parallel to the engine block E and laid through a bracket 10 extending from the engine block E. On this plate 11, a cooling fan 12 is rotatably provided via a fan spacer 13.
그리고 상기 팬스페이서(13)에는 팬구동용 풀리(14)가 고정설치되어 엔진 크랭크축(15)상에 설치된 풀리(16)와 벨트(17)로 연결되어 있다.The fan spacer 13 is fixed to the fan driving pulley 14 and is connected to the pulley 16 and the belt 17 installed on the engine crankshaft 15.
따라서 엔진을 가동하여 크랭크축(15)이 회전하면 그 크랭크축(15)의 회전은 풀리(16,14)와 벨트(17)를 통하여 팬스페이서(13)로 전달되어 그 팬스페이스(13) 선단에 부착된 냉각팬(12)을 회전시키게 되는 것이다.Therefore, when the crankshaft 15 is rotated by operating the engine, the rotation of the crankshaft 15 is transmitted to the fan spacer 13 through the pulleys 16 and 14 and the belt 17 to the tip of the fanspace 13. It is to rotate the cooling fan 12 attached to.
상기한 구조로 된 본 고안에 따르면 엔진 냉각팬이 엔진에 직접 연결설치되어 있지 않으므로 엔진의 크기에 따라 크기가 증가하더라도 엔진부품에 직접 부하를 가하지 않아 엔진부품의 내구성을 향상시킬 수 있다. 특히 냉각팬 및 그 관련부품이 파손되는 등 교체할 필요가 있을 때 엔진과는 직접 연결되어 있지 않으므로 교체수리가 간편한 장점이 있다.According to the present invention having the above structure, since the engine cooling fan is not directly connected to the engine, even if the size increases according to the size of the engine, the durability of the engine parts can be improved by not directly applying a load to the engine parts. In particular, when the cooling fan and its related parts are damaged and need to be replaced, the engine is not directly connected to the engine.
