Abstract
The centrifugal oily steum separating device of a kind of miniature gasoline engine, belongs to miniature gasoline engine technical field.Comprise first half crankcase body (4), later half crankcase body (8), bent axle (1), machine oil case lid (3), oil sealing (2), cam chamber (11), lubricating oil storage chamber (12), oily steum separating device (5); Cam chamber (11), lubricating oil storage chamber (12) are made up of later half crankcase body (4), machine oil case lid (3) and oil sealing (2), it is characterized in that described oily steum separating device (5) is that bent axle (1) is provided with the exhaust port (13) that radial-axial connects in later half crankcase body (4) one end.The utility model has solved existing small-sized four and has rushed that gasoline engine oil air separation separating effect is bad, complex structure, and the problem of the easy oil leakage of working under 360 ° of rotation status, thereby sinking lubrication oil consumption, Economy and the durability of machine are improved, and simple in structure, reliable, easy to maintenance.
Description
Technical field
The utility model belongs to miniature gasoline engine technical field, is specifically related to the centrifugal oily steum separating device of a kind of miniature gasoline engine.
Background technique
On general mini four-stroke gasoline engine, can not under 360 ° of rotation status, work, as notification number: CN201255027Y " the oily steum separating device of petrol engine ", a kind of oily steum separating device of general small gasoline engine is provided, its described technological scheme: the oily steum separating device of petrol engine is arranged between firing chamber and air filter, comprise crankcase and be located at the cylinder head cover at crankcase top, its gas blowby and lubricant mist enter in the circuitous channel 6 of cylinder head cover 2 and separate.And in the time that miniature gasoline engine is worked under 360 ° of rotation status, residing state gas blowby and lubricant mist do not enter in the circuitous channel 6 of cylinder head cover 2 sometimes, thereby there will be oil leak phenomenon.Also there is complex structure, can not solve the disadvantage of oil leak phenomenon under heavy load inversion state in existing several 360 ° of rotation status Xia Youqi mask work mechanisms.
Summary of the invention
The object of the utility model patent is to provide a kind of miniature gasoline engine centrifugal oily steum separating device, and it can overcome the above-mentioned disadvantage of existing miniature gasoline engine, under 360 ° of rotation status, works and there will not be oil leak phenomenon; And reliable in structure, easy to operate.
Above-mentioned goal of the invention is achieved through the following technical solutions realization, and the centrifugal oily steum separating device of a kind of miniature gasoline engine, comprises first half crankcase body, later half crankcase body, bent axle, machine oil case lid, oil sealing, cam chamber, lubricating oil storage chamber,, oily steum separating device; Cam chamber, lubricating oil storage chamber are made up of later half crankcase body, machine oil case lid and oil sealing, and its main points are that described oily steum separating device is that bent axle is provided with the exhaust port that radial-axial connects in later half crankcase body one end; When engine running, the lubricant oil that enters cam chamber can increase gradually, in the time that the oil gas mixing is encountered the bent axle of rotation, liquid lubricant oil can continue lubricating distribution mechanism because got rid of back cam chamber under the centrifugal action of the bent axle rotating, and the exhaust port diffusion that gas can connect to radial-axial, finally from exhaust port discharge, thereby oil, be so incensed that to separate; And the lubricant oil of vapor state also can overflow cam chamber along the exhaust port diffusion connecting to radial-axial, then enter air filter by rubber oil hose, with together with the air-fuel mixture of fresh and vapor state, enter engine chamber and burn, thereby lowered cam chamber oil pressure and reduced pollution of atmosphere.
The beneficial effects of the utility model: be provided with the exhaust port that radial-axial connects in later half crankcase body one end because described oily steum separating device is bent axle, so liquid lubricant oil can continue lubricating distribution mechanism because got rid of back cam chamber under the centrifugal action of the bent axle rotating, and the exhaust port diffusion that gas can connect to radial-axial, finally from exhaust port discharge, thereby oil, be so incensed that to separate; Therefore, oil, gas separate the impact that not worked under 360 ° of rotation status by miniature gasoline engine, effectively prevent that miniature gasoline engine from working and occurring the generation of oil leak phenomenon under 360 ° of rotation status, solve existing small-sized four and rushed bad, the baroque problem of gasoline engine oil air separation separating effect, thereby reduce lubrication oil consumption, improved Economy and the durability of machine; And simple in structure, reliable, easy to maintenance.
