Großwälzlager für rotierende oder schwenkende Bauteile,Slewing bearings for rotating or pivoting components,

zcBe von Kranaufbautenz c B e of crane superstructures

Gegenstand der Neuerung ist ein mittenfreies, vertikalachsiges Großwälzlager zur Aufnahme von Axialkräften, Radialkräften und Kippmomenten, wie sie u0a0 zur Lagerung von Kranaufbauten und Arbeitsbühnen verwendet werden,.Subject of the innovation is a center free, vertikalachsiges large rolling bearing for receiving axial forces, radial forces and tilting moments as are u 0 0 is used for the storage of a crane superstructures and platforms ,.

Eine bekanntgewordene Ausführung eines Großwälzlagers weist einen ersten, in einer horizontalen Ebene geteilten Laufring von U~förmiger Querschnittsgestaltung und einen zweiten, vom ersten umfaßten und gegenüber diesem umlaufenden Laufring auf, wobei,zwischen je zwei einander zugeordneten kreisringförmigen Laufflächen der beiden Laufringe zylindrische Wälzkörper angeordnet sind« Die Zylinderrollen sind dabei in den Taschen geschlossener Käfige aufgenommen, die nicht nur teuer und schwer sind, sondern auch Platz in Anspruch nehmen, der besser zur Unterbringung größerer Rollen und damit zur Erhöhung der Tragfähigkeit des Lagers genutzt werden könnte.One embodiment of a large roller bearing that has become known has a first, in a horizontal plane Split race with a U-shaped cross-section and a second, encompassed by the first and opposite this circumferential race, wherein, between each arranged two mutually associated circular running surfaces of the two races cylindrical rolling elements are «The cylindrical rollers are housed in the pockets of closed cages, which are not only expensive and are heavy, but also take up space, which is better for accommodating larger roles and thus could be used to increase the load-bearing capacity of the warehouse.

Die Neuerung will diesen Mangel beheben und ein Großwälzlager mit optimaler Tragfähigkeit dadurch schaffenj daß die Zylinderrolle:» einenends mit einer ebenen Stirnfläche am Stirnring eines Kammkäfigs und anderenends mit einer balligen Stirnfläche an einer zylindermantelförmigen Fläche des Unförmigen Laufringes anliegen.The innovation aims to remedy this deficiency and thereby create a large roller bearing with optimum load-bearing capacity create that the cylinder roller: "one end with one flat end face on the end ring of a comb cage and at the other end with a spherical face on one cylinder jacket-shaped surface of the misshapen race issue.

Durch die Verwendung eines Kammkäfigs anstelle der bisher verwendeten Käfige mit geschlossenen Taschen können Zylinderrollen untergebracht werden, di© mindestens um das Maß der radialen Höhe eines Käfigstirnringes " länger sind als die bisher in einem Lager gleicher Abmessung unterzubringenden o Die Balligkeit der äußeren Rollenstirnfläche setzt darüber hinaus den Gleitreibungsanteil im Lager herab, so daß nicht nur die Tragfähigkeit sondern auch die Laufeigenschaften des Lagers verbessert werdene By using a comb cage of the cages previously used with closed pockets instead of cylindrical rollers can be housed, di © by the dimension of the radial height of a cage end ring "are at least longer than the previously same in a bearing dimensions to be housed o The crowning of the outer roller end face is moreover the sliding friction component in the bearing down, so that not only the load-bearing capacity but also the running properties of the bearing are improved e

Eine vorteilhafte Ausbildung des Neuerungsgegenstandes sieht vor, daß zwei Reihen unterschiedlich dimensionierter Zylinderrollen in übereinander liegenden parallelen Ebenen angeordnet sind und die in Achsrichtung hintereinander liegenden zylindermantelfönaig©n-Anlaufflächen des Unförmigen Laufringes gleiche Durchmesser aufweisen und daß die Kammkäfig© beider Rollenreihen' radial auf zylindermantelförmigen Flächen des umlaufenden Laufringes geführt sind«An advantageous embodiment of the innovation provides that two rows of different dimensions Cylindrical rollers are arranged in parallel planes lying one above the other and in the axial direction cylinder jacket © n contact surfaces lying one behind the other the same diameter of the misshapen race and that the comb cage © of both rows of rollers' radially on cylinder jacket-shaped surfaces of the are guided by the circumferential race "

Die Zeichnung veranschaulicht ein Ausführungsbeispiel eines Großwälzlagers im Querschnitt als Teilansicht.The drawing illustrates an embodiment of a large roller bearing in cross section as a partial view.

Das dargestellte Wälzlager besitzt einen äußeren, aus zwei ringförmigen Teilen 1 und 2 bestehenden Laufring und einen inneren einteiligen Laufring 3° Die beiden Ringe 1 und 2 sind durch eine Anzahl Schrauben k miteinander verbunden und bilden zusammen einen äußeren Laufring von U—förmiger Querschnittsgestaltung«,The rolling bearing shown has an outer race consisting of two ring-shaped parts 1 and 2 and an inner one-piece race 3 ° The two rings 1 and 2 are connected to one another by a number of screws k and together form an outer race with a U-shaped cross-sectional design «,

Der innere Laufring 3 is* bohrungsseitig mit einem Zahnkranz 5 und mantelseitig mit einem Kragen 6 versehen, der an allen drei freien Seiten geschliffene Laufbahnen für die beiden axial tragenden Rollenreihen 7 und und die radial tragende Rollenreihe 9 aufweist0 Der Kragen 6 wird von dem äußeren Laufring 1,2, der die jeweils anderen. Laufbahnen für die Zylinderrolle^ 7» und 9 aufweist, U-förmig umgriffen.The inner race 3 which is * bore side with a ring gear 5 and the casing side with a collar 6, the cut in all three free sides raceways for the two axially-carrying roller rows 7 and and the radially supporting roller row 9 having 0 The collar 6 is from the outer Race 1,2, each other. Has raceways for the cylindrical roller ^ 7 »and 9, encompassed in a U-shape.

Die Zylinderrollen 7 sind paarweise in den Taschen eines Kammkäfigs aufgenommen, sie stützen sich mit der ebenen Stirnfläche der inneren Rolle 7 am Stirnring des Käfigs 10 und mit der balligen Stirnfläche der äußeren Rolle 7 ^ der zylindermantelförmigen Fläche 1f des Ringes 1 ab<> Der Käfig 10 ist radial auf einer Ringfläche 3« des inneren Laufringes 3 und axial auf einem Ring 11. geführt, der auf dem Kragen 6 ruhto In entsprechender Weise sind auch die dickeren und längeren Zylinderrollen 8 einzeln in den Taschen eines Kammkäfigs 12 geführt, sie stützen sich laigerbohrungsseitig mit ebener Stirnfläche am Stirnring eines Käfigs 12 und andererseits mit balliger Stirnfläche an der zylindermantelförmigen Fläch© 2* des Ringes 2 abo Der Käfig 1,2 ist radial auf einer Ringfläche 3" des inneren Laufringes 3 und axial auf einem Ring 13 geführt, der auf der Laufbahn des Ringes 2 ruhto The cylindrical rollers 7 are received in pairs in the pockets of a comb cage, they are supported with the flat end face of the inner roller 7 on the end ring of the cage 10 and with the spherical end face of the outer roller 7 ^ of the cylindrical surface 1 f of the ring 1 from <> The cage 10 is radially on an annular surface 3 "of the inner race 3 and axially guided on a ring 11, which on the collar 6 rests o in a corresponding manner are also thicker and longer cylindrical rollers 8 individually guided into the pockets of a comb cage 12, they are supported on the laigerbohrungsseite with a flat face on the end ring of a cage 12 and on the other hand with a spherical face on the cylinder jacket-shaped surface © 2 * of the ring 2 o The cage 1,2 is radially on an annular surface 3 "of the inner race 3 and axially on a ring 13 out, which rests on the raceway of the ring 2 o

In der lagerbohrungsseitigen Fläche des Ringes 1 ist eine Nut eingearbeitet, die einen Dichtungsring 1,4 aufnimmt, dessen Dichtlippe auf der ebenen Stirnfläche des inneren Lagerringes 3 aufliegt„In the surface of the ring 1 on the side of the bearing bore incorporated a groove that receives a sealing ring 1.4, the sealing lip of which on the flat face of the inner bearing ring 3 rests "

Die neuerungsgemäßen Merkmale können bei einem Groß« Wälzlager, bei dem der U-förmige Laufring innen und der umlaufende Laufring außen liegens sinngemäß zur Anwendung gebracht werden.The innovation according to characteristics can inside in a large "rolling bearing in which the U-shaped race and the rotating race are outwardly s are brought shall apply analogously.
