Description

Crankshaft ﹠ connecting

Technical field

The utility model relates to crankshaft ﹠ connecting, relates in particular to the crankshaft ﹠ connecting of a kind of internal-combustion piston engine, diesel engine and mechanical compressor.

Background technique

Crankshaft ﹠ connecting is applied on internal-combustion piston engine, the diesel engine, existing very long history.Crankshaft ﹠ connecting mainly is made up of cylinder, connecting rod, bent axle, the microcephaly of connecting rod flexibly connects by the piston of bearing pin and cylinder, the microcephaly of connecting rod and bearing pin can relatively rotate, the major part of connecting rod is connected with the bent neck of bent axle by bearing shell, this bearing shell is fixedlyed connected with the major part of connecting rod, can relatively rotate with the bent neck of bent axle.When this internal-combustion engine needs big power, need a plurality of cylinders to carry out work, can guarantee required power.Because the outburst angle of the cylinder of parallel arranged has only one, cylinder is arranged V-shaped distribution, and its outburst angle also has only two, and matching used so with it bent axle just should be made has the how bent neck length bent axle that equates with number of cylinders.The manufacture cost height of this how bent neck length bent axle has occupied very large space simultaneously, and the volume of entire internal combustion engine is increased, thereby increases the manufacture cost of internal-combustion engine.In addition, in order to reduce the bent axle position occupied as much as possible, the length of its bent neck can not design oversizely, and it is also just bigger to be coated on the pressure that is born on the unit area of the outer bearing shell of bent neck like this, shortened the working life of bearing shell, thereby influence the effective time of internal-combustion engine.

The model utility content

Existing crankshaft ﹠ connecting volume is big in order to overcome, the low problem of outburst angle power few, that provide of cylinder, and the utility model provides that a kind of volume is little, cylinder can be at the crankshaft ﹠ connecting of the arbitrarily angled outburst of bent axle.

The technological scheme that the utility model adopted is: crankshaft ﹠ connecting, comprise cylinder, connecting rod, bent axle, the microcephaly of connecting rod flexibly connects by the piston of bearing pin and cylinder, it is characterized in that: bent axle has only a bent neck, be equipped with at least one cover disk on the bent neck, be provided with bearing shell between disk and the bent neck, bearing shell is fixedlyed connected with disk, and bearing shell and bent neck relatively rotate only; Have two cylinders at least in the one cover disk mechanism, one of them is a master cylinder, the major part of connecting rod is all between two cards of this cover disk, wherein the major part of the connecting rod of master cylinder is fixedlyed connected with the card of disk, the major part of the connecting rod of remaining cylinders is connected with two cards by bearing pin, the major part of this bearing pin and connecting rod can relatively rotate, and the two ends of bearing pin are separately fixed on two cards.

Can wear many cover disks on the described bent neck, form double or arrange the crankshaft ﹠ connecting of multi cylinder more, between every cover disk certain interval be arranged, the major part of every cover disk upper cylinder connecting rod is connected between two cards of disk equally.

A described cover disk is the disk of H shape structure.

The disk of described H shape structure be integral type or the split left and right formula.

The described bearing pin that is connected with connnecting rod big end is evenly to be fixed on the circumference of disk card.

The connecting rod and the disk of described master cylinder are made of one.

The beneficial effects of the utility model are: one, owing to adopt said structure, having changed original multicylinder engine need be with the bent axle of how bent neck, and only need be with the bent axle of single neck, shortened the length of bent axle, reduced the cost of bent axle, further reduce the volume of internal-combustion engine housing simultaneously, reduced cost.Two, owing to have the distance of broad between two cards of a cover disk, bearing shell between disk and bent neck is also with regard to broad, therefore, reduces greatly in that same active force lower bearing unit area is stressed, improve the wear-resistance of bearing pad energy, prolonged the working life of bearing shell.Four, can be distributed on the circumference of bent axle according to the cylinder of required power size configure respective numbers, can realize that easy angle in office all has the clutch release slave cylinder that can break out, thereby improve the power of internal-combustion engine.

Embodiment

An embodiment's of the utility model structure, as shown in Figure 1 and Figure 2, this crankshaft ﹠ connecting mainly comprises: countercylinder 1, slave connecting rod 3, the disk 6 of H shape structure, bent neck 8, bent axle 9, master connecting rod 10, master cylinder 11.Big I according to required drive is provided with a plurality of countercylinders 1, and countercylinder 1, master cylinder 11 are fixed in the internal-combustion engine housing, and bent axle 9 flexibly connects by bearing shell and housing, has only a bent neck 8 on the bent axle 9.The disk 6 of H shape structure is located on the bent neck 8, the disk 6 of H shape structure is the split left and right formula, and promptly the disk body by two inverted T-shaped structures is spliced, and is provided with bearing shell 7 between disk 6 and the bent neck 8, bearing shell 7 is fixedlyed connected with disk 6, and bearing shell 7 relatively rotates only with bent neck 8.The disk 6 of H shape structure also can be made of one formula.The microcephaly of master connecting rod 10 and bearing pin 12 flexibly connect, and the two can relatively rotate, and bearing pin 12 is fixedlyed connected with the piston 13 in the master cylinder 11, and the major part of master connecting rod 10 is fixedlyed connected with two cards between the card of the disk 6 of H shape structure.The microcephaly of slave connecting rod 3 and bearing pin 2 flexibly connect, and the two can relatively rotate, and bearing pin 2 is fixedlyed connected with the piston in the countercylinder 1; The major part of slave connecting rod 3 and is connected with two cards by bearing shell 4, bearing pin 5 between two cards of disk 6, and the major part of bearing pin 5 and slave connecting rod 3 can relatively rotate, and the two ends of bearing pin 5 are separately fixed on the hole of two cards of disk 6.Hole on the card is evenly distributed, and is positioned on the circumference of card.Countercylinder, master cylinder also are uniformly distributed on the circumference of bent axle 9.

On bent neck, also can wear two covers according to the needs of power size or overlap disk more, form double or arrange the crankshaft ﹠ connecting of multi cylinder more, between every cover disk certain interval be arranged.

As another embodiment, as shown in Figure 3, Figure 4, master connecting rod 10 and two disks 6 can also be made of one, and the quantity according to countercylinder 1 on the circumference of disk is provided with corresponding hole 13, hole 13 is uniformly distributed on the circumference of disk 6, and bearing pin 5 is fixedlyed connected with hole 13.

During work, a slave connecting rod 3 and a cover disk 6 form two joint connecting rods, form two joint connecting bar and crankshaft mechanisms with bent axle, and countercylinder 1 outburst promotes its slave connecting rod 3, slave connecting rod 3 promotes disk 6, disk 6 promotes bent neck 8, and bent axle 9 is rotated, owing to fixedly connected between disk 6 and the master connecting rod 10, under the effect of master cylinder 11, make this cover disk 6 can not do the rotation of wide-angle, when promoting bent axle 9 rotations, disk 6 can only carry out translation on general trend, thereby has realized that combustion gas explosive force transfers mechanical force to.
