Abstract: PURPOSE: A camshaft for an engine is provided to improve endurance of the camshaft by locating a welding unit of a hollow shaft on an oil groove-processing unit. CONSTITUTION: A cam shaft of an engine comprises a front end piece(5) installing a cam pulley(3) on a cam shaft(1); a cam(7) formed on an outer portion of a hollow shaft(9); a bolt hole(11) arranged on a front end of the front end piece to mount the cam pulley; am oil seal face(13) mounted on an outer circumference of the bolt hole with a trust face(15); a bearing(19) placed on a neck face(17); and valve lift opening or closing a suction/drain valves by being attached to the cam. A welding unit welded by inserting the front-end piece into the hollow shaft. Thereby, the camshaft of the engine improves endurance of the camshaft by locating the welding unit of the hollow shaft on an oil groove-processing unit.

Abstract: PURPOSE: A welding structure of cam shaft front end piece is provided in which welding ends of a pipe shaped shaft and a round bar shaped front end piece are faced each other so as to be welded by frictional heat thereof. CONSTITUTION: In a cam shaft(1) made by welding a welding end of shaft(1a) on which a plurality of cams(2) are installed to a welding end of front end piece(1b), the welding structure of cam shaft front end piece is characterized in that welding is done by frictional heat generated between the inserting end(11) of the front end piece and the inner diameter of the shaft and between respective welding ends of the front end piece and the shaft by forming an inserting end having outer diameter corresponding to inner diameter of the shaft on the welding end of the front end piece, inserting the inserting end into inner diameter of the welding end, and rotating the front end piece and shaft in a high speed in the state that the welding ends of the front end piece(1b) and shaft(1a) are faced each other.
Abstract translation: 目的:提供一种凸轮轴前端件的焊接结构,其中管状轴和圆棒形前端件的焊接端彼此面对以通过其摩擦热焊接。 构成:在通过将安装有多个凸轮(2)的轴(1a)的焊接端焊接到前端部件(1b)的焊接端而制成的凸轮轴(1)中,凸轮轴前端的焊接结构 其特征在于,通过在前端件的插入端(11)和轴的内径之间以及在前端件和轴的相应焊接端之间产生的摩擦热,通过形成插入端 其外径对应于前端件的焊接端上的轴的内径,将插入端插入焊接端的内径,并且在焊接的状态下高速旋转前端件和轴 前端片(1b)和轴(1a)的端部彼此面对。

Abstract: PURPOSE: A machining structure for rigidity of a bowl edge portion of a direct injection type combustion chamber is provided to improve the rigidity of a bowl edge portion of a combustion chamber and increase the durability. CONSTITUTION: A combustion chamber(2) is formed with a bowl machining after cutting the upper surface of a piston(1). A machining structure for rigidity of a bowl edge portion of a direct injection type combustion chamber is formed on the upper surface of a lip portion(22) of the combustion chamber. A crown machining surface(3) has a larger inner diameter than the diameter of the lip portion. A crown machining surface(3) is downward formed toward the lip portion(22). An edge portion, which is a starting point of the lip portion is increased in the diameter. Thus, the rigidity of an edge portion of a combustion chamber is improved.
Abstract translation: 目的:提供直喷式燃烧室的碗边部的刚性加工结构,以提高燃烧室的碗边部的刚性,提高耐久性。 构成:在切割活塞(1)的上表面之后,燃烧室(2)形成有碗加工。 在燃烧室的唇部(22)的上表面上形成有用于直接喷射型燃烧室的碗边部的刚性的加工结构。 冠加工面(3)的内径比唇部的直径大。 顶面加工面(3)朝向唇部(22)向下形成。 作为唇部的起点的边缘部分的直径增加。 因此,燃烧室的边缘部的刚性提高。
