Abstract
The utility model relates to a valve rocker arm structure of a locomotive engine. A shaft hole is arranged on a valve rocker arm to be assembled with a shaft lever of a cylinder head; an oil collecting groove is concavely formed on the surface of the valve rocker arm; a through hole is arranged in the oil collecting groove to be communicated with the shaft hole; a propping piece is formed at one end of the valve rocker arm to be propped against a cam arranged in the cylinder head; a support leg is formed at the other end of the valve rocker arm, and a propping column is assembled on the support leg, so that the valve rocker arm can be propped against supporting rods of an intake valve and an exhaust valve. Due to the arrangement of the oil collecting groove, the lubricating oil sprayed inside the cylinder head can be effectively collected, so that the lubricating oil is retained in the valve rocker arm for cooling; and additionally, the lubricating oil collected in the oil collecting groove flows into the shaft hole through the through hole of the oil collecting groove for lubricating the fulcrum formed by the shaft hole of the valve rocker arm and the shaft lever of the cylinder head, so that the valve rocker arm swings more smoothly.
Description
Technical field
The utility model is about a kind of locomotive engine porthole rocker structure, refers to especially a kind ofly can cool off the porthole rocking arm really, and the fulcrum place that forms of effectively lubricating porthole rocking arm and the winding of cylinder head axostylus axostyle, and make porthole rocking arm swing porthole rocker structure more smoothly.
Background technique
The engine combustion circulation is to carry out in cylinder head, and in the engine combustion process, main flow process comprises: intake stroke, compression stroke, power stroke and exhaust stroke; Wherein:
Intake stroke: for piston comes downwards to down initial point from last initial point, air intake valve is opened, drain tap is closed, and at this moment, produces partial vacuum in the cylinder head, and gas-air mixture is sucked in the cylinder head;
Compression stroke: oneself goes upward to initial point by following initial point piston, and the inlet and outlet valve is all closed, the mixed gas in the cylinder head is compressed;
Power stroke: the intake and exhaust valve is all closed, and spark plug produces spark, and the mixture combustion that ignites produces powerful thrust, shifts down piston onto initial point by last initial point, produces power;
Exhaust stroke: oneself goes upward to initial point by following initial point piston, and this moment, air intake valve was closed, and drain tap is opened, and the waste gas that had burnt in the cylinder head drains in the atmosphere through drain tap and gas exhaust manifold etc.
So thus in the flow process of engine start, can find that engine advances, the smoothness of the exhaust functions such as engine start horsepower that concern, and the advancing of existing engine cylinder head, the keying of drain tap, controlled by a porthole rocking arm that is mounted in the cylinder head, cam in being located at cylinder head pushes or when discharging the porthole rocking arm, the porthole rocking arm promptly can be to advancing, drain tap is done the action of opening or closing, according to this, to reach engine is advanced, the effect of exhaust, and when the start of porthole rocking arm, the synchronous jet lubrication oil of meeting in the cylinder head in the hope of the temperature of reduction porthole rocking arm, and makes the swing of porthole rocking arm more smooth and easy; Yet; find but that when reality is used this lubricant oil sprays behind the porthole rocking arm, promptly swing fast and rapid scattering along with the porthole rocking arm; can't effectively be attached to the porthole rocking arm; the porthole rocking arm is cooled and lubricated effect, therefore, regular meeting lacks again under enough coolings too fast because of swing during the porthole rocking arm; and overheated situation of burning takes place; and, cause the swing of porthole rocking arm not smooth, so that influence the smoothness of engine inlet and outlet because of being short of enough lubricity.
Therefore, the design people is difficult to cool off and lubricated disappearance in view of the porthole rocking arm of existing engine, be to borrow it for many years in the manufacturing of association area and assisting a ruler in governing a country of design experiences and knowledge, and through clever thought in many ways, the research and development of doing to upgrade at existing engine porthole rocking arm improve, and create the utility model and grind.
The model utility content
The purpose of this utility model is to be to provide a kind of locomotive engine porthole rocker structure, especially a kind ofly can cool off the porthole rocking arm really, and the fulcrum place that forms of effectively lubricating porthole rocking arm and the winding of cylinder head axostylus axostyle, so that porthole rocking arm swing porthole rocker structure more smoothly.
In order to reach above-mentioned enforcement purpose, the utility model proposes a kind of locomotive engine porthole rocker structure, this porthole rocking arm is provided with an axis hole thereon, be arranged with oil trap in porthole rocking arm surface again, porthole rocking arm one end is formed compress sheet, and make the porthole rocking arm hold the shaping leg in addition, and group is provided with to post.
Aforesaid locomotive engine porthole rocker structure, wherein, this porthole rocking arm further is formed with the open-work that communicates with axis hole in the relative axis hole of oil trap place.
