Description
Technical field
The present invention relates to a kind of full-equilibrium single cylinder diesel, belong to the technical field of single cylinder diesel.
Background technique
Greatly, middle-size and small-size single cylinder diesel mainly is made of body part, crankshaft ﹠ connecting, air exchange system, fuel supply system etc., by rotatablely moving of the piston to-and-fro motion in cylinder becoming bent axle, again rotatablely moving of bent axle become the to-and-fro motion of piston, to realize work cycle and external outputting power and each the auxiliary system work that is used for driving motor.Because the pairing linkage mechanism of cylinder all can produce a reciprocal inertia force and rotating inertia force, and the moment of inertia that these two inertial force are also formed two kinds of alternations affacts on the main bearing, these inertial force and moment are not only to diesel engine itself and very unfavorable to the work of outfitting tool, especially has only a cylinder for single cylinder diesel, inertial force that can not self balance diesel engine connecting rod is so need to add the equilibrium problem that extra balanced controls solve connecting rod.At present, the balanced controls that generally adopt of single-cylinder horizontal diesel engine have excessive balance mechanism, uniaxiality balance Agency And spindle balance mechanism.
Excessive balance mechanism adds certain balancing mass on crankshaft balance weight, make bent axle produce excessive inertial force, a part is transferred to Vertical direction along the reciprocal inertia force of cylinder centerline, thereby make single order reciprocal inertia force peak value descend to some extent.
Uniaxiality balance mechanism adds the balancer weight except be positioned at the opposite side of crank pin at bent axle, trunnion shaft of gear driven by the bent axle axle head rotates with unequal angular velocity again, the rotating inertia force that utilizes two balancer weights comes the balance reciprocal inertia force along the component of cylinder-bore axis, and their component perpendicular to cylinder-bore axis is cancelled each other, but because this two power is not point-blank, also can produce unbalanced moment, therefore can only balance part reciprocal inertia force.
Double-shaft balance mechanism adopts two trunnion shafves that two sense of rotation are opposite, size is identical, the centrifugal force of two trunnion shafves reaches balance along the component of cylinder centerline direction and the single order reciprocal inertia force of piston set, but mechanism element quantity is many, and volume and weight is big, the cost height.
Though above-mentioned balanced controls can solve the rotatory inertia equilibrium of forces of connecting rod substantially, but can only partly or entirely balance the single order reciprocal inertia force, all can not solve the equilibrium problem of two-stage reciprocating inertia force, and two-stage reciprocating inertia force is about 1/3～1/4 of single order reciprocal inertia force, so the balanced controls of present single cylinder diesel are because can't the complete equilibrium reciprocal inertia force, be to cause the big main cause of single cylinder diesel ubiquity vibration and noise, both cause noise circumstance to pollute, had a strong impact on user's travelling comfort again.
Summary of the invention
The purpose of this invention is to provide a kind of rational in infrastructurely, compact, can simplify diesel engine body structure and technology, and reduce the full-equilibrium single cylinder diesel of diesel vibration and noise.
The present invention is that the technological scheme that achieves the above object is: a kind of full-equilibrium single cylinder diesel, comprise body and connecting rod, bent axle is installed on body and the bearing cap by main bearing, connecting rod is connected with crankshaft and piston, piston is arranged in the cylinder of body, it is characterized in that: described bent axle be provided with opposite with the crank pin direction before, back two eccentric journals, before, the left side of back two annular connecting rods, right two ends cambered surface is that a concentric and a left side are big, right little cambered surface, before, before back two annular connecting rods pass through, before back two bearings is installed in respectively, two eccentric journal places, back, and right cambered surface is opposite with the crank pin direction, before, before back two annular connecting rods are arranged on, the left side of back two slide blocks, in the right curved guiding surface, before, the back two eccentric journals eccentric distance e with before, back two annular connecting rod active length l ratios equal the ratio of throw of crank shaft R and connecting rod active length L, be installed in the body top before, before back two guide fingers are separately positioned on, in the guiding groove of back two slide blocks, be installed in underpart before, before back two guide rods pass respectively, the pilot hole of two slide block bottoms, back is connected with back shaft, organism sidewall is equipped with gear chamber cover, the gear chamber cover bottom is equipped with oil pump, is provided with crankshaft oil gallery and last oil duct in the gear chamber cover.
The present invention is because with the crank radius of the throw of eccentric between eccentric journal and the main journal as balanced controls, and two annular connecting rod two ends cambered surfaces on two eccentric journals are concentric and different right cambered surface and the left cambered surfaces of radius before and after being installed in, this right side cambered surface and left cambered surface are served as the microcephaly and the major part of annular connecting rod respectively, and with preceding, the right side of back two slide blocks, match in the curved guiding surface of a left side, when bent axle rotates, before, before back two eccentric journals pass through, before back two bearings drives, back two annular connecting rods are done plane turn swing, before then driving, back two slide blocks do reciprocating linear motion in the cylinder centerline direction, before making, the to-and-fro motion track of back two slide blocks and the movement locus conllinear of piston, and moving direction is opposite, form similar opposed two connecting rods, the rotating inertia force of balance crankshaft, and the reciprocal inertia force of piston generation, reach the complete equilibrium of single order and two-stage reciprocating inertia force, reduced the diesel vibration and the noise of single cylinder diesel.In addition, the present invention is because these balanced controls have been cancelled trunnion shaft structure up and down, and do not change structures such as piston, connecting rod, eccentric journal and connected annular connecting rod and slide block only on the bent axle basis, have been increased, and body improved, structural arrangements is more reasonable, compact, takies the body space and reduces, and can further shorten the length of diesel-engine body.
The present invention is installed in gear chamber cover with oil pump, be lubricated by the bent axle and the rocking arm of the oil duct on the gear chamber cover diesel engine, make the lubrication system architecture compactness, improve operational safety, also simplify simultaneously the layout of body, strengthened the body rigidity, improved the manufacturability of body processing, economical with materials reduces the complete machine cost.
