Abstract
The utility model provides a motorcycle engine valve cam lubricating structure and aims to solve the problems that because a motorcycle engine valve cam lubricating structure in the prior art is low in lubrication speed and small in lubricating oil amount, the performance of an engine is affected, noise of the engine is large, the power of the engine is low, and the service life of the engine is shortened. The motorcycle engine valve cam lubricating structure comprises a left crankshaft box. The left crankshaft box is provided with an oil inlet hole, and the oil inlet hole starts from a position above a balance shaft, extends to the upper left position and ends in a valve cam cavity on the left crankshaft box. The motorcycle engine valve cam lubricating structure has the advantages that when the motorcycle engine operates, except that a valve cam can be lubricated in a traditional lubrication method, lubricating oil is directly jetted onto the valve cam through the oil inlet hole, the flow of the lubricating oil of the valve cam is increased, the speed of lubricating the valve cam is improved, in this way, the valve cam can be sufficiently and timely lubricated, the noise of the engine is reduced, the power of the engine is improved, and the service life of the engine is prolonged.
Description
Technical field
The utility model relates to a kind of distribution cam of motorcycle engine structure, specially refers to a kind of distribution cam of motorcycle engine lubricating structure.
Background technique
The lubricating system of distribution cam of motorcycle engine is that oil pump is upwards depressed into cylinder head part by pressure by machine oil in the prior art, and lubricant oil passes through splash lubrication rocking arm, and then by the oil duct on cylinder head and cylinder body, turns back to crankcase body.At lubricant oil, from cylinder head, backflow crankcase body process, valve cam is lubricated.This lubricating system traditional to valve cam, lubricated speed is slow, and it is lubricated that lubricants capacity is few, directly affects the performance of motor, makes its noise large not in time, and power is low, the lost of life.Obviously, prior art distribution cam of motorcycle engine machine lubricating structure exists the problems such as lubricated speed is slow, and lubricants capacity is few, thereby affects the performance of motor, makes its noise large, and power is low, the shortening life-span.
Model utility content
In order to solve the problems such as the lubricated speed of prior art distribution cam of motorcycle engine machine lubricating structure existence is slow, and lubricants capacity is few, thereby affects the performance of motor, makes its noise large, and power is low, the shortening life-span.The utility model proposes a kind of distribution cam of motorcycle engine lubricating structure.
The utility model distribution cam of motorcycle engine lubricating structure, comprises left crankcase, on described left crankcase, is provided with oil inlet hole, and described oil inlet hole arises from balance axis hole top, and extends and end at the valve cam chamber on left crankcase to upper left side.
Further, the diameter of oil inlet hole is 2-3mm.
Further, the angle between oil inlet hole and horizontal line is 20-30 degree.
Further, the length of oil inlet hole is 8-9mm.
The beneficial effect of the utility model distribution cam of motorcycle engine lubricating structure be when motorcycle engine turns round valve cam except traditional lubricating system, lubricant oil is directly ejected on valve cam by oil inlet hole, increased the flow of lubrication of valve cam, accelerated the lubricated speed of valve cam, make the lubricated fully timely of valve cam, reduced engine noise, power improves, life.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model distribution cam of motorcycle engine lubricating structure figure.
Below in conjunction with the drawings and specific embodiments, the utility model distribution cam of motorcycle engine lubricating structure is further described.
Embodiment
Accompanying drawing 1 is the utility model distribution cam of motorcycle engine lubricating structure figure, and in figure, 1 is balance axis hole, and 2 is oil inlet hole, and 3 is valve cam chamber.As seen from the figure, a kind of distribution cam of motorcycle engine lubricating structure, comprises left crankcase, is provided with oil inlet hole 2 on left crankcase, and oil inlet hole 2 arises from balance axis hole 1 top, and extends and end at the valve cam chamber 3 on left crankcase to upper left side.The diameter of oil inlet hole 2 is 2-3mm.Angle between oil inlet hole 2 and horizontal line is 20-30 degree.The length of oil inlet hole 2 is 8-9mm.Lubricant oil of the prior art enters the oil duct of crankcase from machine oil filter screen, be delivered to cylinder head be lubricated by oil pump, and the oil duct of cylinder body flows back into crankcase afterwards, in the process of backflowing, through valve cam lubricated to it.This kind of prior art lubricating system, lubricated speed is slow, and flow of lubrication is few, to the valve cam running up, can not well lubricate.In order to make up this shortcoming, the utility model distribution cam of motorcycle engine lubricating structure has increased by a lubricated channel, above balance axis hole 1, oil inlet hole 2 is set, oil inlet hole 2 arises from balance axis hole 1 top, and extends and end at the valve cam chamber 3 on left crankcase to upper left side.When engine running, lubricant oil is ejected into valve cam from oil inlet hole 2, has increased the flow of lubrication of valve cam, accelerated the lubricated speed of valve cam, made the lubricated fully timely of valve cam, and reduced engine noise, power improves, life.
The beneficial effect of the utility model distribution cam of motorcycle engine lubricating structure be when motorcycle engine turns round valve cam except traditional lubricating system, lubricant oil is directly ejected on valve cam by oil inlet hole, increased the flow of lubrication of valve cam, accelerated the lubricated speed of valve cam, make the lubricated fully timely of valve cam, reduced engine noise, power improves, life.
Although the utility model is described with reference to an explanatory embodiment of the present utility model here, but, should be appreciated that, those skilled in the art can design a lot of other modification and mode of executions, and these are revised and within mode of execution will drop on the disclosed principle scope and spirit of the application.More particularly, in the scope of, accompanying drawing open in the application and claim, can carry out multiple modification and improvement to the constituent elements of subject combination layout and/or layout.Except modification that constituent elements and/or layout are carried out with improving, to those skilled in the art, other purposes will be also obvious.
