Description

오일 토출량 조절장치 {CONTROL DEVICE OF OIL DISCHARGE QUANTITY}Oil discharge amount control device {CONTROL DEVICE OF OIL DISCHARGE QUANTITY}

본 발명은 엔진의 윤활장치에 관한 것으로서, 더욱 상세하게는 중속 이후의 오일 토출량을 일정하게 제어하여 오일 열화방지 및 오일에의 공기혼입방지 등으로 원활한 윤활이 보장되도록 한 오일 토출량 조절장치에 관한 것이다.The present invention relates to an engine lubrication device, and more particularly, to an oil discharge amount adjusting device for ensuring smooth lubrication by preventing oil degradation and preventing air from entering the oil by constantly controlling the oil discharge amount after medium speed. .

일반적으로 엔진의 실린더블록 하부인 실린더의 아랫쪽에는 개스킷을 사이에 두고 오일팬이 설치되어 엔진오일이 담겨진다.In general, the lower part of the cylinder, which is the lower part of the cylinder block of the engine, is installed with an oil pan with a gasket interposed therebetween to hold the engine oil.

이는 엔진내부의 미끄럼운동부(섭동부)에 오일을 공급하여 마찰열로 인한 베어링의 소결 등을 방지하기 위해 미끄럼운동면 사이에 유막을 형성하여 마찰력이 큰 고체마찰을 마찰력이 아주 작은 유체마찰로 바꾸어 주는 작용을 하기 위해서다.In order to prevent oil from sintering of bearing due to frictional heat by supplying oil to the sliding part (perturbation part) inside the engine, an oil film is formed between the sliding surfaces to convert solid friction with high friction to fluid friction with very low friction. To work.

윤활유는 두 섭동면 간의 마찰을 감소시키고 동시에 마멸을 방지하는 고유특성외에 발생된 열을 직접 냉각수나 냉각공기에 전달할 수 없는 부품들을 과열로 부터 보호하는 작용, 즉 윤활부에 발생된 열을 흡수하여 다른 곳에서 방열하는 냉각작용, 실린더 벽과 피스톤 링 사이로 고압가스가 누출되는 것을 방지하는 밀봉작용, 윤활부에 개재되는 불순물을 그 유동과정에서 흡수하여 윤활부를 깨끗하게 하는 세척작용, 윤활면에 부식성 가스나 수분이 침입하는 것을 방지하고 또 침입한 것을 치환하여 마찰면을 비롯한 기관 각부의 부식을 방지하는 방청작용, 국부적으로 작용하는 큰 압력을 윤활유층 전체에 분산시키는 응력분산작용, 및 섭동부 또는 마찰부에 유막을 형성하여 소음과 진동을 감쇠시키는 기관소음 감쇠작용을 한다.Lubricants reduce the friction between the two perturbation surfaces and at the same time protect the parts that cannot directly transfer heat generated from cooling water or cooling air from overheating. Cooling to radiate heat elsewhere, sealing to prevent leakage of high pressure gas between cylinder wall and piston ring, cleaning to absorb lubricating part in the flow process to clean the lubricating part, and corrosive gas on lubricating surface Rust-preventive action to prevent the ingress of moisture and to replace the invasion to prevent corrosion of the engine parts, including the friction surface; stress dispersing action to disperse locally acting large pressures throughout the lubricating oil layer, and perturbation or friction It forms an oil film on the part to act as engine noise attenuation that attenuates noise and vibration.

한편 윤활유의 공급방법으로는, 오일펌프가 없으며 커넥팅로드 대단부에 주걱을 부착하고 이 주걱으로 오일팬내의 오일을 크랭크 축이 회전할 때의 원심력으로 퍼올려 뿌려주는 비산식과, 캠 축에 구동되는 오일펌프로 오일을 흡입,가압하여 각 윤활부로 보내는 압송식, 및 현재 가장 많이 사용되고 있는 것으로 상기 비산식과 압송식을 조합한 비산 압송조합식이 있다.On the other hand, there is no oil pump, and there is no oil pump, and a spatula is attached to the connecting rod end and the spatula is sprayed by the centrifugal force when the crankshaft rotates. Suction and pressurized oil by the oil pump to be sent to each lubrication unit, and the most widely used, there is a scattering pumping combination of the above-mentioned scattering and pressure feeding formula.

압송식 윤활장치는 오일팬, 오일펌프, 오일여과기, 유압조절기로 구성되어 있다.The pressurized lubricator consists of oil pan, oil pump, oil filter and hydraulic regulator.

오일의 유로는 기관 본체의 오일이 순환하는 통로와 오일 파이프로 연결되어 있다.The oil passage is connected to an oil pipe and a passage through which the oil of the engine body circulates.

오일의 순환경로는 오일을 여과하는 오일 여과기의 설치방법에 따라 달라지며 그 방식에는 전류식, 분류식, 복합식이 있다.The circulation path of the oil depends on the installation method of the oil filter for filtering the oil, and there are a current type, a classification type, and a combination type.

이 중에서 주로 쓰이고 있는 전류 여과 압송식 윤활장치의 오일순환 경로를 설명하면, 오일팬에 들어 있는 오일은 우선 스트레이너에서 입자가 비교적 큰 불순물이 제거된 다음, 오일펌프로 뿜어 올린다.The oil circulating path of the current filtration pump type lubricator, which is mainly used, describes the oil contained in the oil pan. First, the relatively large particles are removed from the strainer, and then pumped up to the oil pump.

뿜어 올린 오일은 여과기에서 작은 입자의 불순물이 제거된 다음, 실린더 블록에 마련된 오일통로로 들어간다.The pumped oil is removed from the filter by small particles of impurities and enters the oil passage provided in the cylinder block.

여기에서 각 메인 베어링을 윤활함과 동시에 크랭크 샤프트안의 오일통로에서 크랭크 핀 저어널로 보내져 커넥팅 로드 베어링도 윤활하게 된다.At this time, each main bearing is lubricated, and at the same time, the oil passage in the crankshaft is sent to the crank pin journal to lubricate the connecting rod bearing.

그리고 베어링 끝부분에서 넘쳐나온 오일은 비산하여 실린더 벽과 피스톤 사이의 윤활을 한다.The oil overflowing from the bearing end splashes and lubricates the cylinder wall and the piston.

한편 오일통로에서 실린더 헤드로 압송된 오일은 로커 샤프트의 오일통로를 거쳐서 실린더 헤드위에 마련된 밸브개폐기구를 윤활한다.Meanwhile, the oil pumped from the oil passage to the cylinder head lubricates the valve opening and closing mechanism provided on the cylinder head via the oil passage of the rocker shaft.

커넥팅 로드의 큰쪽에 마련된 오일구멍에서 비산된 오일이 피스톤의 내부를 적시고 피스톤의 냉각도 한다.Oil splashed from the oil hole provided on the larger side of the connecting rod wets the inside of the piston and cools the piston.

그런데 이러한 경로를 거치면서 윤활하는 동안 오일은 열적, 화학적, 기계적 부하를 받게 되는 까닭에 열화되어지는 문제점을 안게 된다.However, the oil is subjected to thermal, chemical, and mechanical loads during lubrication through this path, and thus suffers from deterioration.

또한 오일펌프로 부터의 오일 토출량은 엔진 회전수에 비례하여 증가하게 됨에 따라 중속 이후의 오일펌프는 필요 이상의 오일을 토출하게 되는 폐단이 있다.In addition, since the oil discharge amount from the oil pump increases in proportion to the engine speed, the oil pump after the medium speed has a closed end to discharge more oil than necessary.

필요이상으로 토출된 오일은 윤활 회로상의 바이패스통로를 통해 오일팬으로 회수되는데, 이렇게 회수된 오일이 많게 되면 오일 열화와 오일의 공기 흡입량이 증대하여 원활한 윤활막 형성을 방해하고, 오일 교환주기 및 엔진의 내구력에도 악영향을 끼친다.The oil discharged more than necessary is recovered to the oil pan through the bypass passage on the lubrication circuit. When the recovered oil increases, the oil deterioration and the air intake of the oil increase, which hinders the smooth lubrication film formation, the oil change cycle and the engine. It also adversely affects the durability of the.

본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 중속 이후의 오일 토출량을 일정하게 제어하여 오일 열화방지 및 오일에의 공기혼입방지 등으로 원활한 윤활이 보장되도록 한 오일펌프 속도 조절장치를 제공하는데 있다.The present invention has been made to solve the conventional problems as described above, the object of the present invention is to ensure a smooth lubrication by preventing the oil deterioration and air mixing into the oil by constantly controlling the amount of oil discharge after the medium speed. An oil pump speed control device is provided.

상기 목적을 달성하기 위한 본 발명의 오일 토출량 조절장치는, 크랭크 샤프트의 회전을 변화시키도록 상기 크랭크 샤프트에 원심식 조석기를 설치하고, 오일펌프의 구동 회전수를 제어하기 위해 상기 조속기와 오일펌프 사이에 테이퍼형 변속기어를 설치한 것을 특징으로 한다.The oil discharge amount adjusting device of the present invention for achieving the above object is provided with a centrifugal tidal to the crankshaft to change the rotation of the crankshaft, and between the governor and the oil pump to control the driving speed of the oil pump It characterized in that the tapered transmission gear is installed on the.

상기 특징에 의해 특정 rpm 이후 오일 토출량이 일정하게 된다.Due to the above features, the oil discharge amount is constant after a specific rpm.

이러한 구성으로 크랭크 샤프트(1)가 중속 이상으로 회전하게 되면, 이와 연결된 조속기(2)가 상기 크랭크 샤프트(1)의 회전수를 일정하게 변화시키게 되고, 일정하게 변화된 크랭크 샤프트(1)의 회전수는 다시 테이퍼형 변속기어(4)에 의해 제어되어 이와 연결된 오일펌프(3)의 구동을 일정하게 제어하게 된다.In this configuration, when the crankshaft 1 rotates at a medium speed or more, the governor 2 connected thereto will change the rotational speed of the crankshaft 1 constantly, and the rotational speed of the crankshaft 1 which is constantly changed. Is again controlled by the tapered transmission gear 4 to control the driving of the oil pump 3 connected thereto.

따라서 오일펌프(3)로부터 발생되는 오일팬(5)내의 오일 토출량은 일정하게 되어 오일필터(6)를 통해 기관의 각 오일통로로 공급되고, 기관의 각부위를 윤활시킨후 바이패스통로를 통해 다시 오일팬(5)으로 회수된다.Therefore, the oil discharge amount in the oil pan 5 generated from the oil pump 3 becomes constant and is supplied to each oil passage of the engine through the oil filter 6, and after lubricating each part of the engine, the bypass passage is provided. The oil pan 5 is recovered again.

오일팬(5)내로 회수된 오일량은 중속 이후에도 일정하게 되어 열화되는 것이 방지되고, 또한 그 오일에 공기 혼입이 작게 된다.The amount of oil recovered into the oil pan 5 is kept constant even after the medium speed, and is prevented from deterioration, and the incorporation of air into the oil is small.

즉 엔진의 특정 rpm 이후 오일 토출량이 일정하게 제어되어 과도한 오일 토출량에 따른 제반 문제점이 해소되고, 이에 따라 원활한 윤활작용이 이루어지게 된다.That is, after the specific rpm of the engine, the oil discharge amount is constantly controlled to solve various problems caused by the excessive oil discharge amount, thereby smoothly lubricating.
