Description
Technical field
The present invention relates to a kind of petrol engine, particularly a kind of by stirring the petrol engine that Lubricants is lubricated moving element in the crankcase at a high speed.
Background technique
Available engine is lubricated to be the passage that pumps into lubrication system by oil pump, passage drains into the parts place that each need lubricate with Lubricants, be lubricated then, this lubricating system is lubricated to be limited in scope, the moving element that is positioned at more than the lubricant oil liquid level in the engine crankcase often can't obtain effective lubricating, especially in a single day motor is in heeling condition work, and what the moving element in the crankcase obtained lubricates still less, and the engine operation performance is affected.In addition, cooperate by bearing element between crankcase body and the bent axle, bearing is positioned at lubricant oil liquid level top, and bearing can not get the lubricated of lubricant oil, and in high-speed motion, serious friction can cause damage of bearings, shortens the working life of bearing.
Summary of the invention
The purpose of this invention is to provide a kind of petrol engine, this motor has the fluted disc that impacts lubricant oil at a high speed, makes the lubricated enhancing of engine interior, the inclination when having increased engine operation.
The object of the present invention is achieved like this: crankcase cover is harmonious with the crankcase body that is provided with cylinder, rotating respectively crankcase body and the crankcase cover of being supported in of the crankshaft two end of crankshaft ﹠ connecting, bent axle is provided with timing gear, the gear engagement of timing gear and distribution cam axle, it is characterized in that: the inner chamber of described crankcase cover is provided with a mounting bracket, one is used to stir fluted disc that Lubricants splashes by the rotating mounting bracket that is connected of mandrel, and between the concave arc surface and mounting bracket of crankcase cover, the end face towards mounting bracket that is used to stir the fluted disc that Lubricants splashes is provided with many ribs that are radial extension, rib extends the circumference of fluted disc, leave the gap between rib and the mounting bracket, the other end of described fluted disc is provided with end tooth, the gear engagement of end tooth and distribution cam axle; Described crankcase body is provided with respiratory slot, the channel connection of bent axle supported hole by being provided with on respiratory slot and the crankcase body.
Described mounting bracket is fixedly connected on the bearing of crankcase cover inner chamber setting.
Described bearing is and the integrated bearing of crankcase cover.
Described mounting bracket has and is used to install the supporting portion of fluted disc and the portion that turns back that is used for fixing, and turn back portion and bearing are bolted to connection.
Bent axle supported hole and bent axle on the described crankcase body are slidingly matched.
Describedly be used for stirring the fluted disc that Lubricants splashes and partly stretch into the lubricant oil that is equipped with in the crankcase.
Owing to adopt technique scheme, be provided with a mounting bracket at the inner chamber of crankcase cover, one is used to stir fluted disc that Lubricants splashes by the rotating mounting bracket that is connected of mandrel, makes to have had in the crankcase to be specifically designed to and stirs the fluted disc that Lubricants splashes.This fluted disc is provided with many ribs that are radial extension and stretches out the fluted disc circumference, the bent axle of high speed rotating drives the fluted disc high speed rotating by distribution cam axle, the Lubricants stirring is splash, the Lubricants that splashes is vaporific scattering and splashes, be full of crankcase intracavity, the Lubricants that splashes can carry out sufficient lubrication to moving elements such as the crankshaft ﹠ connecting in the crankcase, distribution cam axle, lower shake-changing arm, speed regulating mechanism, bearings, improves the lubrication effect of moving element in the crankcase.Be provided with many ribs that are radial extension owing to be used to stir fluted disc that Lubricants splashes towards the end face of mounting bracket, rib extends the circumference of fluted disc, leave the gap between rib and the mounting bracket, fluted disc is again between the concave arc surface and mounting bracket of crankcase cover, rib on the fluted disc is in the space of a narrow and small relative closure, rib when making the fluted disc high speed rotating " impacts " Lubricants and forms a space that is similar to " vacuum ", make thus when motor moves in the environmental work of constant slope is arranged, because the Lubricants liquid level position changes, Lubricants also can be stirred to break up to splash, lubricating engine, the inclination when causing engine operation can access increase.
On crankcase body, be provided with respiratory slot, the channel connection of bent axle supported hole on respiratory slot and the crankcase body by being provided with.Make the Lubricants of the respiratory slot into of splashing to enter bent axle supported hole on the crankcase body smoothly from passage like this, when the bent axle high speed rotating, the Lubricants that enters the bent axle supported hole forms " oil film " attached to hole wall, bent axle lubricate to rotation, it is more smooth and easy that bent axle is rotated, can make bent axle and crankcase body adopt sliding matching mode thus, omit the bearing that uses at former this place, save cost.
