Description

Kurbelwellenlager für Hubkolbenmaschinen, insbesondere HubkolbenbrennkraftmaachinenCrankshaft bearings for reciprocating piston engines, in particular reciprocating internal combustion engines

Die Erfindung betrifft ein Kurbelwellenlager für Hübkolbenmaschinen, insbesondere Hubkolbenbrennkraftmaechlnen, deren Teilebene quer zur Längsmittelebene der Maschine verläuft und deren Lagerdeckel hängend angeordnet, in einer Querwand des Maschinengestelle seitlich eingepaßt und mit dieser durch quer zur Maschinealängaiaittelebene gerichtete Schrauben fest verspannt ist.The invention relates to a crankshaft bearing for reciprocating piston machines, in particular reciprocating piston combustion engines, their sub-level runs transversely to the longitudinal center plane of the machine and the bearing cover is arranged hanging in a transverse wall of the machine frame laterally fitted and with this through transversely to the machine longitudinal center plane directional screws is tightly clamped.

Der Hauptlagerdeckel einer Hubkolbenmaschine insbesondere einer Hubkolbenbrennkraftmaschine muß so befestigt sein, daß unter der' Einwirkung der Gas- und Massenkräfte keine Verschiebung gegenüber dem kurbelgehäuseseitigen Teil des Lagers auftritt. Der Lagerdeckel wird üblicherweise durch Schrauben befestigt, die senkrecht zur Teilebene des Lagers gerichtet sind und in Gewindebohrungen des kurbelgehäuseseitigen Lagerteils so eingeschraubt sind, daß die bei einem Arbeitsspiel auftretenden Kräfte den Lagerdeckel nicht verschieben können. Es ist jedoch oft aus Platzgründen nicht möglich, genügend viele und entsprechend bemessene Lagerdeskelschrauben zu diesem Zweck unterzubringen. Man hat daher, um die unerwünschte Verschiebung des Lagerdeckels zu verhindern, den Lagerdeckel zusätzlich in einer Querwand des Maschinengestells seitlich eingepaßt und durch quer zur Maschinenlängsmittelebene gerichtete Schrauben mit der Querwand fest verspannt. Sofern manThe main bearing cap of a reciprocating engine, in particular one Reciprocating internal combustion engine must be fixed in such a way that under the action of the gas and inertia forces there is no shift in relation to it the crankcase-side part of the bearing occurs. The bearing cap is usually fastened by screws that are perpendicular to the plane of the bearing and in threaded holes of the crankcase-side bearing part are screwed in so that the forces occurring during a work cycle hit the bearing cover can not move. However, due to lack of space, it is often not possible to use a sufficient number of appropriately sized bearing screws to accommodate this purpose. You therefore have to To prevent unwanted displacement of the bearing cover, the bearing cover also laterally in a transverse wall of the machine frame fitted and firmly clamped to the transverse wall by screws directed transversely to the longitudinal center plane of the machine.

sich danJaf beschränkt hat, von "beiden Seiten der Querwand nur je eine Querschraube in den Lagerdeckel einzuschrauben, wurden diese Schrauben immer in der Nähe der von der Lagerteilebene abgewandten äußeren Begrenzung des Lagerdeckels angeordnet. Es hat sich gezeigt, daß der angestrebte Zweck durch eine solche Anbringung der seitlichen Schrauben nicht zufriedenstellend erzielt wird.then limited himself to "both sides of the transverse wall only To screw a cross screw each into the bearing cover, these screws were always close to the one facing away from the plane of the bearing part arranged outer limit of the bearing cover. It has been shown that the intended purpose by such an attachment the side screws is not achieved satisfactorily.

k Es ist Aufgabe der Erfin-dung, die Befestigung des Lagerdeckels so auszubilden, daß keine Reibbewegungen auftreten. Dieses wird bei einem Lagerdeckel der eingangs genannten Art dadurch erreicht, daß die Schrauben näher der Lagerteilebene, als der von dieser abgewandten äußeren Begrenzung des Lagerdeckels angeordnet sind. Diese Befestigung unmittelbar an der Lagerteilebene ist wirkungsvoller als an der der Lagerteilebene abgewandten Seite des Lagerdeckels. Gemäß der Erfindung ist es zweckmäßig, daß der Abstand der Schrauben von der Lagerteilebene nicht mehr al3 35 i* des Maßes, gemessen von der Lagerteilebene bis zu der von dieser abgewandten äußeren Begrenzung des Lagerdeckels beträgt. Im Rahmen der Erfindung ist es am günstigsten, wenn der Abstand der Schrauben von der Lagerteilebene so klein ist, wie es die Lagerkonstruktion zuläßt. It is the task of the invention to design the fastening of the bearing cover in such a way that no frictional movements occur. In the case of a bearing cap of the type mentioned at the outset, this is achieved in that the screws are arranged closer to the plane of the bearing part than the outer boundary of the bearing cap facing away from it. This attachment directly to the bearing part plane is more effective than on the side of the bearing cover facing away from the bearing part plane. According to the invention, it is expedient that the distance between the screws and the plane of the bearing part is no longer al3 35 i * of the dimension measured from the plane of the bearing part to the outer boundary of the bearing cover facing away from it. In the context of the invention, it is most advantageous if the distance between the screws and the plane of the bearing part is as small as the bearing construction allows.

Die Zeichnung zeigt das Kurbelwellenlager einer Hubkolbenbrennkraftmaschine im senkrechten Querschnitt.The drawing shows the crankshaft bearing of a reciprocating internal combustion engine in vertical cross-section.

Im Maschinengehäuse 1 ist ein Kurbelwellenlager 2 hängend angeordnet. Die Teilebene 3 dee Kurbelwellenlagers 2 verläuft quer zur Längsmittelebene der Maschina. In die Lagerbohrung, gebildet aus dem Maschinengehäuse 1 mit Lagerdeckel 6 sind die Lagerschalen 4 und 5 eingesetzt. Der Lagerdeckel 6 ist in einer Querwand 7 des Maschinengehäuses 1 seitlich eingepaßt und mit dieser durch quer zur Maschinenlängsachse gerichteten Schrauben 8 fest verspannt. Die Lagerdeckelschrauben 9 sind in bekannter Weise senkrecht zur Teilebene 3 in das Maschinengestell eingeschraubt. Die Schrauben 3 sind erfindungsgemäß näher der Lagerteilebene 3 als der von dieser abgewandten äußeren Begrenzung 10 des Lagerdeckels angeordnet. Der Abstand "a" der Schrauben 8 von der Lagerteilebene 3 soll zweckmäßig nicht mehr betragen, als 35 $ des Maßes, genessen von der Lagerteilebene 3 bis zu der von dieser abgewandten äußeren Begrenzung 10 des Lagerdeckels 6. Aus der Zeichung ist zu ersehen, daß darüber hinaus der Abstand der SchraubenO von der Lagerteilebene 3 so klein gehalten ist, wie es die Lagerkonstruktion erlaubt.A crankshaft bearing 2 is arranged in a suspended manner in the machine housing 1. The partial plane 3 of the crankshaft bearing 2 runs transversely to the longitudinal median plane of the machine. In the bearing bore, formed The bearing shells 4 and 5 are inserted from the machine housing 1 with bearing cover 6. The bearing cover 6 is in a transverse wall 7 of the machine housing 1 fitted laterally and firmly clamped to it by screws 8 directed transversely to the longitudinal axis of the machine. The bearing cap screws 9 are screwed into the machine frame in a known manner perpendicular to the partial plane 3. the According to the invention, screws 3 are closer to the bearing part plane 3 than the outer boundary 10 of the bearing cover facing away from it arranged. The distance "a" of the screws 8 from the plane of the bearing part 3 should expediently not be more than $ 35 of the measure eaten from the bearing part level 3 to the outer boundary 10 of the bearing cap 6 facing away from it. The drawing is closed see that, in addition, the distance of the screws O from the Bearing part level 3 is kept as small as the bearing structure permitted.
