The present invention. refers to a rolling bearing with at least one bearing ring divided transversely to the direction of the axis whose parts of the ring are equipped with annular grooves and are held together in a form fit by means of a connecting element.
Dal DE-OS 3537 985 è noto un cuscinetto volvente con anello diviso in cui le metà dell’anello sono collegate mediante un anello di fissaggio di materiale sintetico. Tali anelli di fissaggio non sono utilizzabili per cuscinetti con grandi diametri per ragioni di costo e per motivi tecnici di produzione. Inoltre, un simile anello di fissaggio non è praticamente più smontabile. From DE-OS 3537 985 a rolling bearing with split ring is known in which the halves of the ring are connected by means of a fastening ring of synthetic material. These retaining rings cannot be used for bearings with large diameters for cost reasons and for technical production reasons. In addition, such a fastening ring can practically no longer be dismantled.
Il compito della presente invenzione è di creare un cuscinetto facilmente montabile del tipo citato all’inizio che possa essere prodotto a costi ridotti e le cuiparti del cuscinetto siano tenute insieme in modo sicuro. The task of the present invention is to create an easily mountable bearing of the type mentioned at the beginning that can be produced at reduced costs and whose parts of the bearing are securely held together.
Tale compito è risolto secondo la presente invenzione tramite il fatto che l’elemento di collegamento è composto da un anello di fissaggio che presenta scanalature anulari e che due anelli elastici sono disposti in modo ingranante sia nelle scanalature anulari delle parti dell’anello del cuscinetto che nelle scanalature anulari dell’anello di fissaggio. Mediante tale preparazione del cuscinetto volvente si attiene che per il montaggio e la scomposizione del cuscinetto non siano necessari attrezzi speciali. This task is solved according to the present invention by the fact that the connecting element is composed of a fastening ring which has annular grooves and that two snap rings are arranged meshing both in the annular grooves of the parts of the bearing ring and in the annular grooves of the retaining ring. Through this preparation of the rolling bearing, it is ensured that no special tools are required for mounting and disassembling the bearing.
Secondo un’ulteriore caratteristica della presente invenzione, l’anello di fissaggio presenta,su uno o su entrambi i lati frontali, rispettivamente una cavità che scopre gli anelli elastici, in modo tale che un attrezzo possa essere introdotto nella linea di separazione dell’anello elastico,che l'anello elastico possa essere allargato e il cuscinetto scomposto. According to a further characteristic of the present invention, the fastening ring has, on one or both front sides, respectively, a cavity which reveals the snap rings, so that a tool can be introduced into the separation line of the ring. elastic, that the snap ring can be widened and the bearing disassembled.
Altre preparazioni della presente invenzione sono descritte nelle sottorivendicaziorii. Other preparations of the present invention are described in the sub-claims.

La forma di attuazione rappresentata nelle figure da 1 a 5 presenta un cuscinetto a rulli cilindrici a due File che è costituito da un anello esterno 1 ad un pezzo, un anello interno 2 diviso trasversalmente alla direzione dell'asse e rulli cilindrici 3. L’anello esterno 1 presenta al centro del foro un margine 4 rivolto radialmente verso l'interno, cui sono adiacenti i rulli cilindrici 3 con le superPici frontali 5. Le parti 6, 7 dell'anello interno sono rispettivamente dotate di due bordi 8, Sa rivolti radialmente verso l’esterno, tra cui sono previsti i rulli cilindrici 3. I rulli cilindrici 3 possono essere introdotti in una gabbia (non disegnata) oppure disposti a rullo pieno. Le part i 6, 7 dell’anello interno sono tenute unite mediante un elemento di collegamento costituito da un anello di fissaggio 9 e da due anelli elastici 10, 11, l’anello di Fissaggio 9 Facendo presa nelle cavità 12, 13 delle parti 6, 7 dell’anello interno. L’anello di fissaggio 9 è dotato nell’ambito delle parti frontali 14 rispettivamente di una smussatura 15 e in uscita dalla superficie laterale 16 di scanalature anulari 17 in cui sono serrati gli anelli elastici 10, Il che fanno presa in scanalature anulari 18 delle parti A, 7 dell’anello interna, in modo tale che le parti 6, 7 dell’anello interno e le restanti parti 1, 3 del cuscinetto siano collegate in un'unità. Gli anelli elastici .10, 1.1 serrati verso l'interno poggiano, allo stato montato, sulla superficie di base 19 delle scanalature anulari 17 mentre tra le superfici laterali 20 degli anelli elastici 10, 11 e le superfici di base 21 delle scanalature anulari 18 nelle parti A, 7 dell’anello interno, è previsto un gioco A. La profondità delle scanalature anulari 18 nelle parti A, 7 dell’anello corrisponde circa all'estensione radiale rifigli anelli elastici 10, il. Durante il montaggio del cuscinetto, i rulli cilindrici 3 di entrambe le file tra i bordi 8, 8a delle parti 6, 7 dell’anello interno e gli anelli elastici IO, 11 sono inseriti nelle scanalature anulari 18 delle parti 6, 7 dell’anello interno. Poi, l’anello di fissaggio 9 è ad es. introdotto nella cavità 13 della parte 7 dell’anello interno finché .l’anello elastico 10, che è allargato attraverso la smussatura 15 dell’anello di fissaggio 9, è fatto scattare nella scanalatura anulare 17 dell’anello di fissaggio 9. Adesso, le parti 6, 7 dell’anello interno sono introdotte con i rulli cilindrici 3 da entrambe le parti nell’anello esterno 1, finché, come si può vedere nella figura 2, la parte sinistra dell’anello di Fissaggio 9 si trova appoggiata all'anello elastico 11. Dopo l’allargamento dell’anello elastico 11, le cui estremità sono separate una dall’altra (figura 3), lo stesso scatta nell’altra scanalatura anulare 17 dell’anello di fissaggio 9 (figura 4), in modo tale che le parti 6, 7 dell’anello interno e tutte le altre parti del cuscinetto siano collegate in un’unità. The embodiment shown in Figures 1 to 5 has a two-row cylindrical roller bearing which consists of a one-piece outer ring 1, an inner ring 2 divided transversely to the direction of the axis and cylindrical rollers 3. The outer ring 1 has at the center of the hole a margin 4 facing radially inwards, to which the cylindrical rollers 3 with the front surfaces 5 are adjacent. The parts 6, 7 of the inner ring are respectively provided with two edges 8, Sa facing radially outwards, between which cylindrical rollers 3 are provided. The cylindrical rollers 3 can be introduced into a cage (not drawn) or arranged with a full roll. The parts 6, 7 of the inner ring are held together by means of a connecting element consisting of a fixing ring 9 and two elastic rings 10, 11, the fixing ring 9 By gripping the cavities 12, 13 of the parts 6 , 7 of the inner ring. The fastening ring 9 is provided in the context of the front parts 14 respectively with a chamfer 15 and at the outlet from the lateral surface 16 with annular grooves 17 in which the elastic rings 10 are tightened, which engage in annular grooves 18 of the parts A, 7 of the inner ring, so that the parts 6, 7 of the inner ring and the remaining parts 1, 3 of the bearing are connected in one unit. The snap rings 10, 1.1 tightened inwardly rest, in the assembled state, on the base surface 19 of the annular grooves 17 while between the lateral surfaces 20 of the snap rings 10, 11 and the base surfaces 21 of the annular grooves 18 in the parts A, 7 of the inner ring, a play A is provided. The depth of the annular grooves 18 in parts A, 7 of the ring corresponds approximately to the radial extension of the snap rings 10, il. During assembly of the bearing, the cylindrical rollers 3 of both rows between the edges 8, 8a of the parts 6, 7 of the inner ring and the snap rings 10, 11 are inserted into the annular grooves 18 of the parts 6, 7 of the ring internal. Then, the fixing ring 9 is e.g. introduced into the recess 13 of the inner ring part 7 until the snap ring 10, which is widened through the chamfer 15 of the fastening ring 9, is snapped into the annular groove 17 of the fastening ring 9. Now, the parts 6, 7 of the inner ring are introduced with the cylindrical rollers 3 on both sides into the outer ring 1, until, as can be seen in figure 2, the left part of the fastening ring 9 rests against the ring elastic 11. After widening the snap ring 11, the ends of which are separated from each other (figure 3), it snaps into the other annular groove 17 of the fastening ring 9 (figure 4), so that that parts 6, 7 of the inner ring and all other parts of the bearing are connected in one unit.
Per lo smontaggio del cuscinetto è prevista una cavità 22 nell’anello di fissaggio 9, attraverso la quale può essere inserito un attrezzo (non disegnato) dal foro dell'anello interno nella linea di separazione 23 dell'anello elastico 11 e l’anello elastico 11 può essere allargato in modo che sia possibile tirare fuori le parti 6, 7 dell’anello interno con i rulli cilindrici 3 dalia cavità 24 dell’anello esterna l. For disassembly of the bearing there is a cavity 22 in the retaining ring 9, through which a tool (not drawn) can be inserted from the hole of the inner ring into the parting line 23 of the snap ring 11 and the snap ring 11 can be widened so that it is possible to pull out the parts 6, 7 of the inner ring with the cylindrical rollers 3 from the cavity 24 of the outer ring 1.
La presente invenzione non è limitata alla forma di attuazione descritta. Così è ad esempio possibile prevedere anelli elastici serrati verso l’esterno che prima del montaggio del cuscinetto siano disposti in scanalature anulari dell’anello di fissaggio e che aprendo le parti dell’anello interno siano premute, mediante smussature delle parti dell’anello interno, in scanalature anulari dell’anello di fissaggio e poi scattino nelle scanalature anulari delle parti dell’anello interno. The present invention is not limited to the embodiment described. Thus it is possible, for example, to provide snap rings tightened towards the outside which are arranged in annular grooves of the fastening ring before mounting the bearing and which by opening the parts of the inner ring are pressed, by means of chamfering of the parts of the inner ring, into the annular grooves of the retaining ring and then snap into the annular grooves of the inner ring parts.
Inoltre anche l’anello interno e/o l'anello esterno possono essere eseguiti in modo diviso trasversalmente alla direzione dell’asse ed essere tenuti uniti rispettivamente mediante un elemento di collegamento. Furthermore, also the inner ring and / or the outer ring can be executed in a divided way transversely to the direction of the axis and be held together respectively by means of a connecting element.
