Abstract
본 고안은 캠 샤프트 베어링을 제거한 차량용 엔진에 관한 것인바, 특히 OHC 타입 엔진의 캡과 서포트 사이에서 내설되는 베어링을 제거하고, 상기 캡과 서포트 사이에 오일 그로브를 가공하여 오일을 공급함으로 베어링 제작 및 개발 비용을 절감할 수 있으며, 조립에 따른 유용성을 구현하기 위한 것으로, 캡; 상기 캡에 대응하여 조립되는 서포트를 갖는 OHC 엔진에 있어서, 상기 캡과 서포트의 내주면으로 충분하게 오일이 공급될 수 있도록 오일 그로브가 형성됨을 특징으로 한다.The present invention relates to a vehicle engine with a camshaft bearing removed. In particular, a bearing manufactured by removing an internal bearing between a cap and a support of an OHC type engine and processing an oil grove between the cap and the support to supply oil is manufactured. And to reduce the development cost, to implement the usefulness of the assembly, the cap; In the OHC engine having a support assembled to correspond to the cap, characterized in that the oil grove is formed so that the oil can be sufficiently supplied to the inner peripheral surface of the cap and the support.
Description
일반적으로 차량용 OHC타입 엔진의 대부분에 있어서는 첨부 되어진 도면 1에서와 같이 캡과 서포트를 정밀 가공한 다음 베어링을 장착한 후 조립하여 사용한다.In general, in most vehicle OHC engines, caps and supports are precisely machined as shown in the attached drawing 1, and then used after assembling bearings.
주지하다시피, OHC타입의 엔진에서는 실린더 헤드부에 캠 샤프트가 장착되어 있는 바, 이와 같은 캠 샤프트에 형성되는 3~4개소의 저널부에는 베어링이 지지되어 있으며, 앞부분에는 밸브 개/폐시기를 나타내는 타이밍 마크를 새겨넣은 타이밍 기어가 장치되어 있는 것이다.As is well known, the camshaft is mounted on the cylinder head in the OHC engine, and the bearings are supported on three to four journals formed on the camshaft. The timing gear which engraved the timing mark shown is provided.
상기와 같은 캠 샤프트는 흡입밸브, 배기밸브와 같은 수의 캡을 밸브 개/폐시기에 맞춘 위치와 각도를 배려하기 위한 것으로서 캡과 서포트 사이의 베어링은 원활한 캠 샤프트의 구동에 매우 필요한 역할을 수행한다.The cam shaft as described above is to consider the position and angle of the number of caps such as the intake valve and the exhaust valve in accordance with the opening and closing time of the valve, the bearing between the cap and the support plays a very necessary role for smooth driving of the cam shaft do.
그러나, 상기와 같은 베어링의 장착에 따라 상기 베어링을 제작하거나 개발하기 위한 과다한 비용이 소요되었고, 조립 및 설치에 따른 작업시간의 과다 소요와 작업자의 번거러움을 유발시킴은 물론 공정의 추가가 필요하게 된다는 문제점을 포함한다.However, according to the mounting of the bearings, excessive costs were required to manufacture or develop the bearings, and excessive work time due to assembly and installation, causing inconvenience for the workers, and of course, additional processes were required. Contains the problem.
따라서, 캡과 서포트 사이의 베어링을 제거하되, 캠 샤프트의 원활한 구동에 영향이 없도록 배려되어야 한다.Therefore, while removing the bearing between the cap and the support, care should be taken not to affect the smooth drive of the camshaft.

상기 본 고안의 목적 및 요망 사항을 달성하기 위해 본 고안은 캡; 상기 캡에 대응하여 조립되는 서포트를 갖는 OHC엔진에 있어서, 상기 캡과 서포트의 내주면으로 충분하게 오일이 공급될 수 있도록 오일 그로브가 형성됨을 특징으로 한다.The present invention to achieve the object and the requirements of the present invention cap; In the OHC engine having a support assembled to correspond to the cap, it is characterized in that the oil grove is formed so that the oil can be sufficiently supplied to the inner peripheral surface of the cap and the support.
이하, 첨부도면을 참조하여 보다 구체적으로 본 고안의 바람직한 실시예를 설명한다.Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.
첨부된 도 2는 본 고안에 의해, 캠 샤프트 베어링이 제거된 차량용 엔진의 평면도인바, OHC엔진에 있어서 캠 샤프트가 긴밀하게 내설되어 지지될 수 있도록 마련되는 캡(10)과 상기 캡(10)의 상호 대응하여 긴밀하게 조립 체결되는 서포트(20)가 제공되는데, 이때 상기 캡(10)과 서프트(20)의 조립에 따라 형성되는 내주면으로 베어링을 제거한 채 캠 샤프트의 구동에 필요한 충분한 오일이 공급될 수 있도록 오일 그로브(30)를 형성시키는 것이다.2 is a plan view of a vehicle engine in which a cam shaft bearing is removed by the present invention, and the cap 10 and the cap 10 are provided to be supported by the cam shaft in an OHC engine. Corresponding to each other, the support 20 is provided to be closely assembled and fastened, wherein sufficient oil for driving the cam shaft is supplied with the bearing removed to the inner circumferential surface formed by the assembly of the cap 10 and the support 20. It is to form the oil grove (30) to be.
이와 같은 본 고안은 오일 그로브(30)에 의한 오일의 공급으로 베어링의 역할을 대체 수행할 수 있어 베어링 제작과 개발비용을 절감할 수 있으며, 조립 또한 간편하게 이루어져 경제적인 유용함을 부여한다는 것이다.The present invention can replace the role of the bearing by the supply of oil by the oil grove 30 can reduce the bearing manufacturing and development costs, it is also easy to assemble and give economical usefulness.
본 고안은 캠 샤프트 베어링을 제거한 차량용 엔진에 관한 것인바, 특히 OHC타입 엔진의 캡과 서포트 사이에서 내설되는 베어링을 제거하고, 상기 캡과 서포트 사이에 오일 그로브를 가공하여 오일을 공급함으로 베어링 제작 및 개발 비용을 절감할 수 있으며, 조립에 따른 유용성을 구현하기 위한 캠 샤프트 베어링을 제거한 차량용 엔진을 제공한다.The present invention relates to a vehicle engine with a camshaft bearing removed. In particular, a bearing manufactured by removing an internal bearing between a cap and a support of an OHC type engine and processing an oil grove between the cap and the support to supply oil is manufactured. And it can reduce the development cost, and provides a vehicle engine with a cam shaft bearing removed to implement the usefulness of the assembly.
