Abstract
The utility model provides a crankcase, include the crankcase case lid and be located the dead eye on this case lid, be equipped with the antifriction bearing who is used for supporting the bent axle in the dead eye, it has the bush mounting hole of installing the bent axle bush to open on the interior terminal surface of case lid, the bush mounting hole coaxial and link up with the dead eye with the dead eye. Wherein, it has the bush oil duct to open on the bent axle bush, the one end of bush oil duct link up with the case lid oil duct on the crankcase case lid, and the crank pin pair link up on the other end and the bent axle. The utility model also provides an adopt the diesel engine of this crankcase. The utility model discloses a bent axle both ends all adopt antifriction bearing to support, the easy inclined to one side mill problem that appears of reduce friction coefficient and slide bearing. Increase a lubricating oil bush, this bush only can not being used for supporting role to the crank pin fuel feeding. Lubricated oil duct works independently with the bearing, even the bearing failure can not result in having guaranteed because of the lubricated not enough connecting rod locking circumstances that produces that the bent axle crank pin is lubricated yet.
Description
Technical field
The utility model relates to engine parts and application thereof, refers to especially a kind of crankcase and adopts this bent axleThe diesel engine of case.
Background technology
Air-cooled diesel engine is the internal combustion engine as fuel with diesel oil, and the heat energy that fuel combustion is discharged is converted intoThe device of electric energy or mechanical energy. The support of existing small air-cooled diesel engine bent axle all adopts rolling bearing on one sideThe supporting construction of one side sliding bearing in addition. Adopt sliding bearing, its coefficient of friction is far longer than rolling bearing,Lubricating condition requirement to bearing is higher, and meanwhile, the required precision to parts in manufacture process is also comparedHeight, otherwise easily inordinate wear causes bearing failure. Maintenance inconvenience after sliding bearing lost efficacy, needs to changeWhole crankcase cover, maintenance cost is higher. Sliding bearing is simultaneously as lubricated necessity of moving componentPassage, once lose efficacy, whole engine lubrication lost efficacy, and there will be the situation of connecting rod locking.
Utility model content
The utility model proposes a kind of crankcase, increase the rolling bearing of crankcase case lid end, reduce friction andEccentric wear, the life-span of prolongation crankcase; Increase a machine oil lining, ensure that crankshaft pin is lubricated.
The technical solution of the utility model is achieved in that a kind of crankcase, comprises crankcase case lid and positionDead eye on this case lid, is provided with the rolling bearing for supporting bent axle in described dead eye; Described case lidInner face on have the lining installing hole that crankshaft collar is installed, described lining installing hole is coaxial with dead eyeAnd connect with dead eye.
Wherein, on described crankshaft collar, have lining oil duct, one end of described lining oil duct and crankcase case lidOn case lid oil duct connect, crank-pin kinematic pair perforation on the other end and bent axle.
Particularly, described dead eye is counterbore, and described rolling bearing is positioned at the position at place, counterbore large aperturePlace; In described counterbore, position place, small-bore is provided with oil sealing.
Further, on described oil sealing, the one end away from rolling bearing adds around oil sealing along the directional ring at bearing placeWork has flange, and described flange and oil sealing form an annular chamber.
Further, the large aperture end of described lining installing hole and dead eye connects.
Further, in the case lid oil duct on described crankcase case lid away from one end of lining oil duct be provided withThe gas thread that screwed pipe coordinates.
Further, between described crankshaft collar and crankcase case lid, be connected by dormant bolt.
The utility model also provides a kind of diesel engine that adopts above-mentioned crankcase, and described diesel engine using is above-mentionedCrankcase, reduce the wearing and tearing of diesel engine, extend the life-span of diesel engine.
Compared with prior art, the beneficial effects of the utility model are: crankshaft two end all adopts rolling bearing to prop upSupport, reduces the eccentric wear problem that coefficient of friction and sliding bearing easily occur. Increase a lubricating oil lining,This lining only, for to crank-pin fuel feeding, does not play a supportive role. Oil leab and bearing work independently, evenBearing failure, can not cause the connecting rod locking situation that produces because of lack of lubrication yet, has ensured crankshaft pinLubricated. The utility model can be good at improving the service life of engine, particularly specific use (peculiar to vessel)Equipment, reduced cost and the cycle of maintenance simultaneously. And rolling bearing has been realized standardization, seriesChange, generalization, its accuracy of manufacture and uniformity and quality are more prone to control.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below by rightIn embodiment or description of the Prior Art, the accompanying drawing of required use is briefly described, apparently, belowAccompanying drawing in description is only embodiment more of the present utility model, for those of ordinary skill in the art,Do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of another state of the utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, to the technical side in the utility model embodimentCase is clearly and completely described, and obviously, described embodiment is only that the utility model part is realExecute example, instead of whole embodiment. Based on the embodiment in the utility model, ordinary skill peopleMember, not making the every other embodiment obtaining under creative work prerequisite, belongs to the utility modelThe scope of protection.
Referring to Fig. 1, Fig. 2, a kind of crankcase, comprises crankcase case lid 2 and is positioned at the dead eye on this case lid,In described dead eye, be provided with the rolling bearing 1 for supporting bent axle; Crankshaft two end all adopts rolling bearing 1 to support,Reduce the eccentric wear problem that coefficient of friction and sliding bearing easily occur. On the inner face of described case lid, have peaceThe lining installing hole of crankshaft collar 3 is housed, and described lining installing hole is coaxial and connect with dead eye with dead eye.Increase a crankshaft collar 3, this crankshaft collar 3, only for to crank-pin fuel feeding, does not play a supportive role.
Wherein, on described crankshaft collar 3, have lining oil duct 5, one end of described lining oil duct 5 and crankcaseCase lid oil duct on case lid 2 connects, and on the other end and bent axle, crank-pin kinematic pair connects.
