Description
본 발명은 자동차의 윤활장치에 관한 것으로, 더욱 상세하게는, 자동차용 엔진에서 오일을 분사하는 오일젯의 내부에 설치되어 유압에 따라 오일의 흐름을 조절하는 볼을 지지하는 것으로, 외주부에는 나사가 형성되어 있으며, 스톱링에 의해 볼 장착볼트에 끼워져 볼의 이탈을 막을 수 있는 구조의 볼 시트를 구비한 윤활장치의 오일젯 결합구조에 관한 것이다.The present invention relates to a lubrication device for an automobile, and more particularly, to support a ball installed in an oil jet for injecting oil in an automobile engine to control oil flow according to hydraulic pressure, and a screw The present invention relates to an oil jet coupling structure of a lubrication device having a ball seat formed in the ball mounting bolt by a stop ring and preventing the ball from being separated.
일반적으로, 자동차용 윤활장치는 엔진의 작동을 원활하게 하고 수명을 다할 때까지 운동 마찰 부분에 엔진오일을 지속적으로 공급하는 역할을 하는 것으로, 4행정 기관에서는 대부분 압송식과 비산식을 겸한 비산 압송식을 채용하고 있다. 비산 압송식은 오일펌프가 오일 스트레이너를 통해서 흡입한 윤활유를 각 윤활부로 압송함과 동시에, 실린더벽과 피스톤 핀에는 커넥팅 로드의 대단부가 오일팬에 저장되어 있는 윤활유를 비산하여 공급하는 방식이다.In general, the automotive lubricator serves to continuously supply the engine oil to the kinetic friction part until the engine operates smoothly and reaches the end of its service life. It is adopted. The splash pump type pumps the lubricating oil sucked through the oil strainer to each lubricating part, and scatters the lubricating oil stored in the oil pan at the most end of the connecting rod to the cylinder wall and the piston pin.
이와 같이 오일펌프에 의해 오일팬으로부터 압송된 오일은 오일젯(oil jet)을 통해 크랭크 샤프트에 형성된 오일 공급홀로 분사되어 윤활작용을 하는데, 그에 대한 구조를 다음의 도 1에서 설명한다.The oil pumped from the oil pan by the oil pump is lubricated by being injected into an oil supply hole formed in the crankshaft through an oil jet, and the structure thereof will be described in FIG. 1.
도 1은 종래의 오일젯 결합구조를 보인 반단면도로, 이것의 전체적인 구성을 보면, 오일을 분사하는 오일젯(2)과, 결합핀(8)에 의해 오일젯(2)이 끼워져 있는 본체(4)와, 일단에는 오일 파이프가 조립되는 파이프 고정나사(6b)가 형성되어 있고, 내부에는 볼(10)이 탄성적으로 장착되는 볼 장착볼트(6)와, 볼(10)의 이탈을 방지하기 위한 볼 시트(16)로 이루어져 있으며, 볼(10)은 가압 스프링(14)에 의해 지지되어 있는 플런저(12)를 통해 가압된 상태에서 유압에 따라 상하로 이동하면서 오일젯(2)을 통해 배출되는 유량을 조절하게 된다.1 is a half sectional view showing a conventional oil jet coupling structure. In view of its overall configuration, an oil jet 2 for injecting oil and a main body in which the oil jet 2 is fitted by the coupling pin 8 are shown. 4) and a pipe fixing screw 6b on which one end of the oil pipe is assembled, and a ball mounting bolt 6 on which the ball 10 is elastically mounted, and a separation of the ball 10 is prevented. It consists of a ball seat 16 for the ball 10 is moved through the oil jet (2) while moving up and down in accordance with the hydraulic pressure in the pressurized state through the plunger 12 supported by the pressure spring (14) The discharge flow rate is controlled.
이러한 구성을 지닌 종래의 오일젯 결합구조에서는 볼의 이탈을 막기 위해 장착하는 볼 시트(16)의 조립시에는 볼 시트(16)의 외경을 볼 시트(16)가 장착되는 볼 장착볼트(6)의 삽입홀(6a)의 내경보다 크게 형성한 다음, 억지끼워맞춤하여 조립하므로, 작업성이 저하되는 문제가 있다.In the conventional oil-jet coupling structure having such a configuration, when assembling the ball seat 16 mounted to prevent the ball from being separated, the ball mounting bolt 6 to which the ball seat 16 is mounted may have an outer diameter of the ball seat 16. Since it is formed larger than the inner diameter of the insertion hole (6a) of the insertion hole, and fits and assembles, there is a problem that workability is reduced.
이와 같은 문제점을 해결하기 위해 안출된 본 발명은 볼의 이탈을 막기 위해 끼우는 볼 시트의 외주부에 나사를 가공하여 볼 장착볼트의 삽입홀에 나사 결합함과 동시에, 스톱링을 장착하여 나사의 풀림을 방지할 수 있는 윤활장치의 오일젯 결합구조를 제공하는데 그 목적이 있다.The present invention devised to solve such a problem is to process the screw in the outer periphery of the ball seat to prevent the separation of the ball screwed into the insertion hole of the ball mounting bolt, and at the same time to install the stop ring to loosen the screw It is an object of the present invention to provide an oil jet coupling structure of a lubricator that can be prevented.
