Description
Technical field
The invention relates to a kind of bent axle that comprises many crank throws that is used for cross-type two-stroke diesel engine, wherein crank throw is made up of two crankwebs that linked together by crank pin, and intactly interconnected by many main journals, bent axle longitudinally is divided at least two bent axle parts simultaneously.
Background technique
In large cross-head formula two stroke IC engine field, this bent axle is widely known by the people.Because its weight is big, and relative rotational is low, so its static load as the weight of internal combustion engine component, is exactly a main design standard, and in the internal-combustion engine of small-sized fast turn-around, the power that is produced by moving-mass is only main design standard.For example, the large cross-head formula two stroke IC engine in patent DK1053/96 is known.This internal-combustion engine has many cylinders, is necessary so that bent axle is divided into two or more parts, and this is because otherwise the weight of whole bent axle will exceed weight limits.That is to say that the lifting capacity that for example is applied in the hoist in Production of Crankshaft equipment and the internal-combustion engine mounting equipment is limited in about about 220 tons.This internal-combustion engine with 8 to 14 cylinders, the weight of whole bent axle in its maximum model approximately is about 500 tons, and hoist can not be raised this whole bent axle, so it is necessary that bent axle longitudinally is divided at least two parts.The assembling bent axle is the top of partly hanging base by with each bent axle, subsequently they is transferred on the main bearing.Then, by being connected with each other with bolt, the flange on the bent axle part free end carries out bent axle assembling again.In a single day the bent axle part is placed on the main bearing, they just can only move in limited scope vertically.Therefore, other shrinkage assembling that is used to connect main journal and crank throw can not be used, this is that part has a sizable displacement vertically because such connection needs bent axle, but when bent axle partly was placed on the main bearing, sizable axial displacement was impossible realize.Therefore, up to now,,, flange is considered to easily so connecting because assembling can only be carried out in very limited shaft orientation moving range.In flange connected, the bent axle part was transferred on the main bearing one by one by complete vertical support, only reserves a spot of space between flange.Flange/bent axle part is by alignment, and bolt inserts in the hole on two flanges.Bolt is tightened then, and assembling is finished.Flange connects and to be considered to more advantageously because it can transmit very big moment of torsion, can transmit peak value up to about 12 in moment, the moment of torsion of 000KNm.
For example according to patent DK1053/96, be in the large combustion machine of 2000KW at the minimum output power of each cylinder, its crank throw be in order to carry the load that is applied thereto, and has to make an integral body by casting or forging and follow-up machining.
But, be positioned at the entire length that flange between bent axle part free end has increased bent axle, therefore, increased total length and the weight of internal-combustion engine.As noted earlier, weight is the design link of a key, and therefore, it is very important reducing weight.For example, when internal-combustion engine is used for freighter, and each inch of the loading cargo hold in the freighter is all very important, so the total length of internal-combustion engine is just very crucial.
Summary of the invention
Under this background, the purpose of this invention is to provide a kind of bent axle that reduces length overall above-mentioned.According to claim 1, this purpose can realize that the realization that the crank portion branch interconnects is by the part of separated type crank throw and another part of this separated type crank throw are coupled together by the mode that the crank portion branch is interconnected.Different with initial stage hypothesis is that separated type crank throw of structure is proved to be feasible, and it just can sustain the load that is applied thereto like this, the moment of torsion that is transmitted as quilt, the active force that applies by connecting rod and the weight of connecting rod self.Therefore, it is feasible needn't utilizing the flange that takies length just can partly couple together bent axle.By using this bent axle, this internal-combustion engine is compared with feasible program up to now, and shorter length and lighter weight can be arranged.The minimizing of length is very favourable in the situation of part, because just connecting, the flange in patent DK1053/96 just is added on simply between crank throw and the main journal, therefore, this has increased by what flange connected that length connects and connects nearest axle journal and connect distance between the axle journal of the other end at flange from flange.The distance that increases between these main journals or the crank throw of a reinforcing need be arranged between main journal perhaps need have higher stress level in the crank throw that must accept.
Two crankwebs of separated type crank throw all can radially be divided into an interior section and an exterior section, and thus, exterior section is radially intactly interconnected by crank pin.
Stud bolt in the respective aperture in the interior section that extend into is radially arranged in the exterior section radially.The most handy nut screwing clamping of stud bolt is clamped on radially the exterior section with interior section that will be radially.
Avoid wearing and tearing in order to protect to connect, the material that can increase frictional force is used between the interior section radially and the surface of contact between the exterior section radially of separated type crank throw.This connection can by further improved mode be by guarantee radially interior section and the area of contact between the exterior section radially in fact less than the cross sectional area of crankweb, so that contact pressure is higher.
Another kind of protection ways of connecting is in radially interior section and the connection between the exterior section radially the stud bolt of cooperation and/or fitted bolt to be arranged.
According to the present invention, the more purpose of bent axle, characteristics, advantage and characteristic will be explained in detailed description.

There are several diverse ways can guarantee being connected between main journal 5 ' and crankweb 3 ' to transmit huge peak value up to 12, the moment of torsion of 000KNm.These methods are alternative method or additional method.Stud bolt 8 in the connection of a better embodiment or bolt 8 ' have formed required size and have been applied in prestressing force, so that the frictional force between the surface of contact of main journal 5 ' and crankweb 3 ' last adjacency surpasses shearing force.
Another method that increases the torque-transfer capability that connects is to use the material that can increase frictional force between the free end of the free end of main journal 5 ' and crankweb 3 '.But can increase the material nickel coating of frictional force, a but coating that contains the relative soft metal masterplate of hard particles preferably, its thickness is greater than the thickness of metal stencil plate, so that particle partly is being pressed in the free-ended surface of contact of the free end of main journal 5 ' separately and crankweb 3 ' in the assembling, and form miniature sawtooth effectively surface of contact is locked together mutually.Metal stencil plate contains nickel, the alloy of ferro-alloy or other metal.Hard particles comprises carbide, as silicon carbide, and Tungsten carbite, chromium carbide and/or oxide, as chromium oxide, silica or other hardening oxidation thing.This particle in fact must be harder than main journal 5 ' and crankweb 3 '.The material that can increase frictional force can be used thermal blanket, as plasma coating.Material directly is applied on main journal 5 ' and the crankweb 3 ' is fine, still, be preferably on the both sides of disk 15 and use the material that can increase frictional force.Shown in legend preferable among Fig. 4, this disk 15 is inserted between the free end of the free end of main journal 5 ' and crankweb 3 '.When connection must be experienced assembling several times and assemble, utilizing disk 15 was very useful as the carrier that can increase the material of frictional force.By new disk of each usefulness, the functional of material that can increase frictional force just is guaranteed.
Another guarantees to connect the method that can transmit huge moment of torsion is to utilize the cooperation stud bolt 8 or the fitted bolt 8 ' that do not have backlash that is assemblied in hole 7 and the hole 9.Cooperating stud bolt/fitted bolt to help to increase connection in fact bears the ability of shearing force and a good alignment is provided between main journal 5 ' and crankweb 3 '.It also is feasible using nutted rod/turnbuckle and cooperating the assemblying body of stud bolt/fitted bolt.
Shown in Figure 7 is second better embodiment of the present invention.The formation of bent axle part 1a and 1b is with identical method recited above, promptly crank throw 2 by main journal 5 by complete interconnecting.But bent axle partly is to interconnect by the separated type crank throw 2 ' shown in detail in Fig. 8 and Fig. 9.Crankweb 3 be divided into interactional radially exterior section 3a and interior section 3b radially.
Two exterior section 3a radially of crank throw 2 ' interconnect by crank pin 4a.Exterior section 3a radially and crank pin 4a be an integral body, and perhaps they link together by shrinking to connect with crank pin 4a.Each exterior section 3a radially has two tapped holes that are used for holding stud 18.Stud 18 extends by the hole in the corresponding interior section 3b radially tangentially.Also available stud more than two in each crank arm.Stud 18 stretches out from the hole of radially interior section 3b.Be used to tighten stud 18 so that interior section 3b radially and exterior section 3a radially firmly are clamped together with the nut 19 of stud 18 thread engagement.
The surface of contact 21 of the surface of contact 20 of exterior section 3a radially and interior section 3b radially adjoins each other and is in the same place.As shown in the figure, surface of contact preferably be positioned at stud 18 around, but they also can be positioned at other position, as symmetry axis around crankweb 3.
Also have several diverse ways to be used for guaranteeing when internal combustion engine operation, under the influence of suffered shearing force, exterior section radially can not move with respect to interior section radially.These methods are alternative method or additional method.Stud 18 in a better embodiment has formed required size and has been applied in prestressing force, surpasses shearing force so that interior section 3b radially and exterior section 3a radially go up the frictional force of 20,21 of the surface of contact of adjacency.So far, make that the surface area of 20,21 of surface of contact is favourable for a short time, like this height that contact pressure will be relative.According to the deformable body of this mode of execution, the material of increased frictional force as described above is used in 20,21 of surface of contact.This material that increases frictional force as on the surface of contact 20,21 or a thin insert (not shown) on coating be employed, be coated with the friction reducing agent on the both sides of this thin insert.This insert is placed between the surface of contact 20,21.Guaranteeing to connect another method that can bear shearing force is to use cooperation stud 18 that does not have backlash that is assemblied in the hole or the assemblying body of using nutted rod 18 and fitted bolt, or the assemblying body of other type depending post.
Exterior section 3a radially has an arc protrusion 22 that radially extends in inside, and it is that hollow chamfer 24 forms a space, and this hollow chamfer 24 is the effects of blurting out that are used for avoiding transition position between crank pin 4a and the exterior section 3a radially.Interior section 3b radially has one accordingly for holding the recess 23 of protrusion 22.
Although the present invention illustrates this purpose with description, these details only are only at this purpose certainly, and those variations that do not depart from the scope of the invention in the prior art field all exist.
Therefore, although according to their development environment the preferred forms of apparatus and method is described, they are explanation of the principles of the present invention.Other mode of execution and structure also can be designed in the scope that does not depart from purport of the present invention and claim.
