Description
Technical field
The utility model relates to petrol engine, relates in particular to a kind of lubricating structure of petrol engine.
Background technique
At present, most of general gasoline engines all is through stirring oily mechanism or independent oil pump is lubricated petrol engine.Wherein, adopting the lubricating system stir oily mechanism mainly is to rely on to be positioned to stir oily device or mechanism under the pasta, through its high speed rotating oil is stirred to nebulize, and then makes vaporific oil attached to each component surface, to play lubrication; And the lubricating system of employing oil pump needs transmission system of specialized designs to rotate to drive oil pump, realizes pressure lubrication.And in using; There is limitation in the lubricating system that oily mechanism is stirred in employing: can not lubricate some specific zone; Promptly can not realize the pressure lubrication of fixing a point, when using no bearing rotation such as float petrol box body and bent axle, this kind lubricating system just can not satisfy its lubricating requirement; Adopt the lubricating system of oil pump,, need specialized designs one transmission system, increased complete machine cost and machine volume though can realize the fixed point pressure lubrication.
The model utility content
The purpose of the utility model is to provide a kind of lubricating structure of petrol engine, and this lubricating structure not only can make machine oil carry out pressure lubrication to specified position, but also can reduce machine volume and reduce the complete machine cost.
The purpose of the utility model is achieved in that
A kind of lubricating structure of petrol engine is characterized in that: it comprises eccentric mechanism, piston mechanism and swing-bar mechanism; Said eccentric mechanism comprises camshaft, is provided with oil input channel, oil road and oily passage in this camshaft; Said piston mechanism comprises pump oil jacket and pressure channel; Said swing-bar mechanism comprises the ball that is fixedly mounted on the petrol engine, and the pump oil piston that links to each other with ball; One end of said oil input channel links to each other with oily passage, and this oil passage also is connected with an end and the pressure channel of oil road simultaneously; Camshaft is set to eccentric wheel in the corresponding position of this oil passage, and this eccentric wheel is outside equipped with the pump oil jacket, and pressure channel passes the pump oil jacket and links to each other with the pump oil piston.
In the above-mentioned swing-bar mechanism, the pump oil piston can be the center rotation with the ball that is fixedly mounted on the petrol engine, and it can also rotation.
The utlity model has following beneficial effect:
In the lubricating structure of the utility model petrol engine, because the pump oil jacket is mounted on the eccentric wheel of camshaft, the ball end that the pump oil piston connects is installed on the petrol engine; When petrol engine was worked, camshaft can rotate under the drive of bent axle, because the existence of eccentric mechanism is arranged; And owing to the ball end of pump oil piston is fixed; It can only rotate around the ball end, and therefore, the circular movement of camshaft has just changed into the straight line motion of pump oil jacket; So camshaft is done straight-line pump oil jacket and the formation of the pump oil piston in pump oil jacket piston motion relatively.The process that pressure channel changes from small to big is an oil-absorbing process, and process from large to small is for pressing oily process.The utility model structural design is ingenious, has both practiced thrift the space, has realized the fixed point pressure lubrication again, thereby has improved the life-span of petrol engine, and has reduced the complete machine cost.

Embodiment
Through embodiment the utility model is specifically described below; Be necessary to be pointed out that at this; Following examples only are used for the utility model is further explained; Can not be interpreted as the restriction to the utility model protection domain, the person skilled in the art in this field can make some nonessential improvement and adjustment to the utility model according to above-mentioned model utility content.
Shown in Figure of description 1-5, a kind of lubricating structure of petrol engine, it comprises eccentric mechanism 11, piston mechanism 9 and swing-bar mechanism 10; This eccentric mechanism comprises camshaft 7, and be provided with oil input channel 2 in the camshaft 7, oil road 8 and oily passage 1; Its piston mechanism 9 comprises pump oil jacket 3 and pressure channel 4; Its swing-bar mechanism 10 comprises the ball 6 that is fixedly mounted on the petrol engine, and the pump oil piston 5 that links to each other with ball 6; One end of its oil input channel 2 links to each other with oily passage 1, and this oil passage 1 also is connected with an end and the pressure channel 4 of oil road 8 simultaneously; Camshaft 7 is set to eccentric wheel in this oil passage 1 corresponding position, and this eccentric wheel is outside equipped with pump oil jacket 3, and pressure channel 4 passes pump oil jacket 3 and links to each other with pump oil piston 5; The ball 6 that pump oil piston 5 can be fixedly mounted on the petrol engine is the center rotation, and it can also rotation.
Because pump oil jacket 3 is mounted on the eccentric wheel of camshaft 7; The spheric end of pump oil piston 5 is installed on the petrol engine and can only rotates; Can not rotate with pump oil jacket 3, when petrol engine was worked, camshaft 7 can be made circular movement under the drive of bent axle; By the existence that eccentric wheel structure is arranged on it; The circular movement of camshaft 7 has just changed into the linear relative movement of pump oil jacket 3, so relative camshaft 7 is done straight-line pump oil jacket 3 and the pump oil piston 5 in pump oil jacket 3 has formed piston motion in pressure channel 4.When the eccentric wheel of camshaft 7 when proximal part turns to distal end; Machine oil will get in the pressure channel 4 through the oil input channel in the camshaft 72; When eccentric wheel during from distal end to proximal part; Machine oil is just extruded from pressure channel 4 by pump oil piston 5, and getting into each through the oil road in the camshaft 78 needs in the lubricating structure (proximal part and distal end are eccentric relatively centers of rotation).
