[산업상 이용분야][Industrial use]
본원 발명은 피스통이 실린더내에서 왕복 운동을 할 때 고속 회전운동 하는 핀 보스부의 윤활성을 향상시킨 윤활장치에 관한 것이다.The present invention relates to a lubrication device that improves the lubricity of the pin boss portion that rotates at high speed when the piece cylinder reciprocates in the cylinder.
[종래기술][Private Technology]
피스톤에는 복수개의 링홈이 형성되어 있으며 피스톤과 실린더 사이의 틈새를 통해 압축 가스나 연소가스가 새는 것을 방지하기 위하여 상부에서부터 1개 내지 3개, 통상 2개로 구성되는 링홈에는 압축링이 끼워지며 압축링의 하부의 링홈에는 제3도에 도시된 것과 같이 오일링(5)이 끼워진다.A plurality of ring grooves are formed in the piston, and a compression ring is fitted in a ring groove composed of one to three, usually two, from the top to prevent the leakage of compressed gas or combustion gas through the gap between the piston and the cylinder. The ring groove of the oil ring 5 is fitted as shown in FIG.
오일링(5)에는 링의 전 둘레에 걸쳐 홈이 파여 있고 또 몇 곳에는 오일창(14)이 뚫려 있다. 실린더 내에 공급되어 윤활에 사용된 여분의 오일(윤활유)은 상기 오일링(5)에 의해 긁어져 내리게 되며 긁어진 여분의 오일은 상기 오일창(14)을 통하여 오일링(5)의 뒷면에 이르게 되고 여기서 다시 링홈(2)에 연통하는 배유구(8)를 거쳐 피스톤 안쪽으로 나가 크랭크 케이스로 떨어진다.The oil ring 5 is grooved over the entire circumference of the ring, and the oil window 14 is drilled in some places. The excess oil (lubricating oil) supplied to the cylinder and used for lubrication is scraped off by the oil ring 5 and the scraped excess oil reaches the rear of the oil ring 5 through the oil window 14. Here, through the drain hole 8 which communicates with the ring groove 2 again, it goes out into the piston and falls into the crankcase.
또한, 고속 회전 운동하는 피스톤 핀을 섭동하도록 지지하는 보스부(10)에는 하부로부터 비산되는 오일이 섭동부위에 공급됨과 아울러 별도의 윤활유 주입구(15)를 통해 윤활유를 공급받고 있다.In addition, the boss portion 10 supporting the piston pin to rotate at a high speed is supplied with oil splashed from the lower portion to the perturbation portion and is supplied with lubricating oil through a separate lubricating oil inlet 15.
[종래기술의 문제점][Problems with Prior Art]
그러나 상기와 같은 피스톤 핀 보스부에의 윤활방식은 충분한 윤활유 공급이 곤란하여 윤활성이 좋지 못하다고 하는 문제점이 지적되고 있다.However, it has been pointed out that the lubrication method to the piston pin boss portion as described above is difficult to supply sufficient lubricating oil and thus the lubrication is not good.

본원 발명은 상기한 문제점을 감안하여 안출한 것으로서 그의 목적으로 하는 바는 오일링이 끼워진 링홈의 배유구로부터 배출되는 여분의 윤활유를 피스톤 핀 보스부에 공급하도록 하므로써 윤활성을 향상시킨 피스톤 핀 보스부에의 윤활장치를 제공하는 데 있다.The present invention has been made in view of the above problems, and its object is to provide a piston pin boss portion with improved lubricity by supplying the piston pin boss portion with extra lubricant oil discharged from the drain hole of the ring groove in which the oil ring is fitted. To provide a lubrication device.
[과제를 달성하기 위한 수단][Means for achieving the task]
상기한 과제를 달성하기 위한 본원 발명의 구성은Configuration of the present invention for achieving the above object is
오일링이 끼워지는 링홈과, 링홈에 연통하는 복수개의 배유구와를 갖는 피스톤에 있어서,A piston having a ring groove into which an oil ring is fitted and a plurality of drain ports communicating with the ring groove,
상기 배유구와 피스톤 핀 보스부에 형성된 윤활구멍을 연결시키므로써 상기 오일링에 의해 긁혀내려 배유구를 통해 배출되는 윤활유가 상기 배유구와 연통하는 윤활구멍을 통해 피스톤 핀 보스부에 공급되도록함을 특징으로 하고 있다.By connecting the lubrication hole formed in the drain port and the piston pin boss portion, the lubricant oil scraped off by the oil ring and discharged through the drain port is supplied to the piston pin boss portion through the lubrication hole communicating with the drain hole. It features.
[실시예]EXAMPLE
이하, 본원 발명의 실시예를 첨부한 도면을 참조하여 설명한다.Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
제1도는 본원 발명 피스톤 윤활장치의 일실시예를 나타내는 반단면도이며,1 is a half cross-sectional view showing an embodiment of the piston lubricator of the present invention,
제2도는 본원 발명 윤활장치의 변형된 실시예를 나타내는 도면이다.2 is a view showing a modified embodiment of the present invention lubricator.
도면중 부호 1은 피스톤이며, 피스톤(1)에는 복수개의 링홈(2)(3)(4)이 형성되어 있으며 상부 2개의 링홈(3)(4)에는 압축링(6)(7)이 끼워져 있으며 하부 링홈(2)에는 오일링(5)이 끼워져 있다.In the drawing, reference numeral 1 denotes a piston, and a plurality of ring grooves 2, 3 and 4 are formed in the piston 1, and compression rings 6 and 7 are fitted in the upper two ring grooves 3 and 4, respectively. The oil ring 5 is fitted in the lower ring groove 2.
오일링(2)으로부터는 오일링(5)에 의해 긁혀 내려진 여분의 오일을 배출하기 위한 복수개의 배유구(8)가 피스톤 몸체 내부로 뚫려 있으며 상기 배유구(8)는 피스톤 핀(9)을 섭동지지하는 피스톤 핀 보스부(10)에 윤활유를 공급하는 윤활구멍(11)에 연통하고 있다.From the oil ring (2) a plurality of drain holes (8) are drilled into the piston body for discharging excess oil scraped off by the oil ring (5), and the drain holes (8) open the piston pin (9). It communicates with a lubrication hole 11 for supplying lubricating oil to the perturbed piston pin boss portion 10.
상기 배유구(8) 하나하나마다에 윤활구멍(11)을 대응시키기가 곤란할 경우 피스톤(1)의 원주방향으로 형성되어 각각의 배유구(8)를 공통으로 연결하는 배유구 연결통로(12)를 형성할 수 있으며 이 경우 각각 배유구(8)를 통해 배출되는 여분의 윤활유가 상기 배유구 연결통로(12)를 거쳐 한곳으로 수집된 후 윤활구멍(1))을 통하여 피스톤 핀 보스부(10)에 공급된다.When it is difficult to correspond the lubrication holes 11 to every one of the drain holes (8) is formed in the circumferential direction of the piston (1), the drain hole connecting passage 12 for connecting the respective drain holes 8 in common In this case, the excess lubricating oil discharged through the drain port 8 is collected through the drain port connecting passage 12 into one place, and then the piston pin boss portion 10 through the lubrication hole (1). Is supplied.
제2도는 변형된 실시예로서 핀 보스부(10)의 상부로 수평으로 연장하는 오일수집홈(13)을 마련한 후 각 배유구(8)로부터 배출되는 윤활유를 오일수집홈(1)에 모은 후 오일수집홈(13)으로부터 연통하는 윤활구멍(11)을 통하여 피스톤 핀 보스부(10)에 윤활유를 공급하게 되며 공급되고 남는 여분의 윤활유는 오일수집홈(13)을 넘쳐 흘러 크랭크케이스로 떨어지게 된다.FIG. 2 is a modified embodiment, after preparing an oil collecting groove 13 extending horizontally to the upper part of the pin boss part 10, and collecting the lubricant oil discharged from each drain port 8 into the oil collecting groove 1, The lubricating oil is supplied to the piston pin boss 10 through the lubricating hole 11 communicating from the oil collecting groove 13, and the remaining excess lubricant flows over the oil collecting groove 13 and falls into the crankcase. .
[효과][effect]
이상과 같은 본원발명에 의하면 피스톤과 실린더의 마모 누설 방지를 위해 사용된 윤활유를 링홈에 형성된 배유구를 통해 그대로 배출하지 아니하고 배유구 연결 통로 및 윤활구멍을 통해 피스톤 핀 보스부에 공급하게 되므로써 피스톤 핀의 섭동 부위에 충분한 윤활유를 공급하여 안정된 유막을 형성하므로써 마찰력을 저감시켜 마모를 줄이고 방열효과를 높이게 된다.According to the present invention as described above, the piston pin is supplied to the piston pin boss portion through the drainage connecting passage and the lubrication hole, rather than being discharged as it is through the drain hole formed in the ring groove. By supplying enough lubricating oil to the perturbation part of the to form a stable oil film, frictional force is reduced to reduce wear and increase heat dissipation effect.
