Abstract

The invention relates to a lubricating structure of an engine, which belongs to the technical field of power devices. It is mainly composed of an engine case and a cylinder head. The overhead cam transmission mechanism is supported in the valve operating room through the supporting shaft. The branch valve operating system is installed in the valve operating room. The crankshaft is supported in the crankcase. The chain tensioning device is installed In the crankcase, a decompression device is installed on one side of the overhead cam transmission mechanism. The present invention has a simple, compact and reasonable structure; since an oil groove is provided at the upper opening of the engine body and the bottom of the valve operating chamber, the oil mist and splash lubricating system are used to provide the intake and exhaust cams and the driven The lubrication between the sprocket and the support shaft can evenly supply lubricating oil to all parts of the valve operating system, suppress the heat generated by the high-speed rotation of the driven sprocket of the intake and exhaust cams, ensure the reliable operation of the engine, and ensure that the intake and exhaust cams Sufficient lubrication of the contact part with the valve rocker arm.

Description

technical field [0001] The invention relates to a lubricating structure of an engine, in particular it can evenly provide lubricating oil to each part of a valve operating system, and belongs to the technical field of power devices. Background technique [0002] Before the present invention was made, in the prior art, the lubricating structure of the engine usually used a cam top-mounted mechanism. This structure canceled parts such as tappets and push rods and adopted chain or toothed belt transmission, and its advantage was that there were fewer reciprocating parts. , Cancel the tappet and push rod, the whole mechanism has high rigidity, and the vibration caused by the reciprocating mass inertia force at high speed is the smallest, which is suitable for high-speed running engines. But the disadvantage of this structure is that it is difficult to provide enough lubricating oil between the support shaft and the intake and exhaust cams and the driven wheel, which is easy to c...
