Description

오일홈을 갖춘 캠샤프트Camshaft with Oil Groove

제1도는 본 고안의 캠사프트의 측면도이다.1 is a side view of the cam shaft of the present invention.

* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings

1 : 저어널(Journal)부 2 : 캠샤프트1: Journal part 2: Camshaft

3 : 오일홈3: Oil groove

본 고안은 오우버헤드밸브(Over Head Valve)를 갖는 엔진에 장착되는 캠샤프트 구조에 관한 것으로, 특히 상기 캠샤프트의 저어널(Journal)부에 오일홈을 형성시킨 개량식 캠샤프트에 관한 것이다.The present invention relates to a camshaft structure mounted on an engine having an over head valve, and more particularly, to an improved camshaft in which an oil groove is formed in a journal part of the camshaft.

통상적으로 오우버헤드밸브를 갖는 엔진에 있어서 캠샤프트의 저어널부가 실린더 블럭측에 메탈 또는 베어링을 장착하지 않고 상기 실린더블럭측에 지지되어 구동되어지도록 되어 있는데, 이러한 종래구조는 오일이 상기 캠샤프트에 원활하게 공급되지 못하게 되면 상기 캠샤프트의 캠표면이 쉽게 마모되어지거나 캠샤프트가 소착되어질 수 있는 원인을 제공하였다.Typically, in an engine having an overhead valve, the journal portion of the camshaft is supported to be driven by the cylinder block side without mounting a metal or bearing on the cylinder block side. If the cam shaft is not supplied smoothly, the cam surface of the cam shaft may be easily worn or the cam shaft may be sintered.

이에 본 고안은 상기와 같은 문제점을 해결하기 위해 안출해 낸 것으로, 캠샤프트에 오일이 지속적으로 균일하게 공급되어질 수 있도록 되어 있는 오일홈을 갖춘 캠샤프트를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, it is an object of the present invention to provide a cam shaft with an oil groove that can be supplied to the cam shaft continuously and uniformly.

상기와 같은 목적을 달성하기 위한 본 고안은 저어널부를 갖춘 캠샤프트에 있어서, 상기 저어널부의 원주방향으로 오일홈을 형성시킨 구조로 되어있다.The present invention for achieving the above object has a structure in which an oil groove is formed in the circumferential direction of the journal portion in the cam shaft having the journal portion.

이하 본 고안을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 고안에 따른 오일홈을 갖춘 캠샤프트는 공지의 저어널부(1)를 갖추어 이루어진 캠샤프트(2)에 있어서, 상기 저어널부(1)각각에 원주방향으로 오일홈(3)을 형성시킨 구조로 되어있다.Camshaft having an oil groove according to the present invention is a cam shaft (2) having a known journal portion (1), the journal portion (1) in each of the structure to form an oil groove (3) in the circumferential direction It is.

제1도에 도시된 바와같이 본 고안은 캠샤프트(2)의 저어널부(1)에 오일홈(3)을 원주방향으로 형성시킴에 따라 이 캠샤프트(2)가 도면에 도시되지 않은 실린더블럭에 지지되어 구동되어질 때 상기 캠샤프트(2)의 저어널부(1) 전외주면에 지속적으로 균일한 오일이 공급되어 원활한 윤활작용을 제공함에 따라 종래와 같이 상기 캠샤프트의 캠표면이 쉽게 마모되어지거나 소착되어지는 것을 예방할 수가 있다.As shown in FIG. 1, the present invention forms an oil groove 3 in the journal portion 1 of the cam shaft 2 in the circumferential direction, so that the cam shaft 2 is a cylinder block not shown in the drawing. The cam surface of the camshaft is easily worn as in the prior art by supplying uniform oil continuously to the front and outer circumferential surface of the journal portion 1 of the camshaft 2 when it is supported and driven. It can prevent the sintering.

상기와 같이 본 고안은 캠샤프트(2)에 원활한 오일이 공급되어지도록 저어널부(1)에 오일홈(3)을 형성시킴에 따라 상기 캠샤프트의 소착현상을 방지할 수 있도록 되어있다.As described above, the present invention is configured to prevent seizure of the cam shaft by forming an oil groove 3 in the journal portion 1 so that the smooth oil is supplied to the cam shaft 2.

Claims (1)

(정정)오우버헤드밸브를 갖춘 엔진에 장착되어 저어널부를 갖추어 이루어진 캠샤프트에 있어서, 상기 저어널부(1) 각각의 원주둘레면에 오일을 유도할 수 있는 오일홈(3)을 형성하여, 상기 저어널부(1)의 바깥둘레에 오일이 공급되어 밸브계와 윤활접촉을 원활하게 함을 특징으로 하는 오일홈을 갖춘 캠샤프트.(Correction) In the camshaft mounted to the engine having an overhead valve provided with a journal portion, by forming an oil groove (3) for inducing oil on the circumferential peripheral surface of each of the journal portion (1), Camshaft having an oil groove characterized in that the oil is supplied to the outer circumference of the journal portion (1) to facilitate lubricating contact with the valve system.
