Abstract

The large size ball bearings (1) are located between an elastic inner shell (2) and an outer support surface. The inner shell is shaped to clip over a smaller bearing (9) and has cut-outs to locate the balls without requiring a cage. The larger bearing is protected by an elastic flange (13). The bearing is simple to repair, by replacing the ball bearings with larger sizes. The drive flange on the output shaft is secured to the axle stub (5) by a simple external weld (7).

Description

bETR,: Neuanmeldung einer WellenlagerungbETR ,: New registration of a shaft bearing

Der Erfindung liegt die Lagerung von Antriebswellen und insbesonderse die spannungefrei bleibende Wälzlagerabstützung von Kardansträngen in Kraftfanrzeugen zugrunde. Die heut meist anzutrefende Abstützung dieser Wellen ist ein elastisches Zwischenglied über welches das Wälzlager der Welle mit dem Fanrzeugrahmen verbunden ist. Elastizitat und Steifigkeit dieser Ausf@hrung sind ausreichend zur Dämpfung aufkommender Schwingungen und auch um dem wechselseitingen Radialdurck standzuhalten, wie er von im Fahrzeug abgewinkelter Gelenkwellen verursacht wird.The invention is the storage of drive shafts and in particular the tension-free rolling bearing support of cardan assemblies in motor vehicles underlying. The most common support for these waves today is elastic Intermediate member via which the roller bearing of the shaft is connected to the fan tool frame is. The elasticity and rigidity of this design are sufficient for damping arising vibrations and also to withstand the alternating radial pressure, as it is caused by cardan shafts angled in the vehicle.

Die Nachgiebigkeit wie sie aber notwendig wär, Bautoleranzen plus Bewegungen der Welle in axialer Richtukng auszugleichen ist Errahrungsgemaß bei diesen Abstützungen zu gering und somit auch ibre Lebensdauer. Zum Auswechsein des Verschleißteiles muß be-Kanntlich die Antriebswelle ausgebaukt uknd auch zerlegt werden.The flexibility as it would be necessary, plus construction tolerances To compensate for movements of the shaft in the axial direction is required by the experience These supports are too low and therefore also their service life. To replace the As is known, the drive shaft must be dismantled and dismantled as a wear part will.

zieel der Erfindunf war es, neben der Beseitigung dieser annartenden Mangel Herstell- und wartungskosten einer Zweschenwelle zu senken und ihr Grewicht zu reduzieren. Beim Auswechsein der Verschleißunterliegenden Teile werden Rugeln (1) durch größere ersetzt und/oder der Lageraufnahering (2) durch Segmente ersetzt.The aim of the invention was, besides the elimination of this annartenden Deficiency to reduce manufacturing and maintenance costs of an intermediate shaft and its weight to reduce. When replacing the parts that are subject to wear and tear, the balls become (1) replaced by larger ones and / or the bearing mounting ring (2) replaced by segments.

Dabei wird das dem Hohlzylinder (3) haltende Teil (4) abgeschraub.The part (4) holding the hollow cylinder (3) is unscrewed.

Die sonsst notwendige, verschraubte Steckverzahnung Wellenzapfen (5)/ Flalnsch (6) kann die kostengünstigere Festverbindung Schweißen (& ) ersetzt werden. Bei dieser Festverbindung wird der Flanschanschluß (8) geringer beansprucht und erlaubt eine leichtere Ausfuhrung.The otherwise necessary, screwed spline shaft journal (5) / Flalnsch (6) can replace the cheaper fixed connection welding (&) will. With this fixed connection, the flange connection (8) is less stressed and allows an easier execution.

Hauptmkerkmal einer spannungstrel bleibenden Lagerabstütung für Geienkwellen ist der Lageraufnanmerinß (2) aus Gummi oder ähulich elastischen Materials, der auch ausd Segmenten Besteheb kann.Main feature of a stress relieved bearing support for Geienk shafts is the bearing receptacle (2) made of rubber or similar elastic material, the can also consist of segments.

Er ist innenseitig zur Aufnahme eines Wälzlagers mit einer M-förmigen Ringnut (9) versenen. Die Lagerringaußenseite hat Ausnehmungen (10) die den begrenzten Laut einer Kugel in axialer Richtukng ung partallel zu den m-Schragstrichen (9) der Innenseite zulesen.It is inside to accommodate a rolling bearing with an M-shaped Shave the ring groove (9). The outer side of the bearing ring has recesses (10) which are limited According to a sphere in the axial direction parallel to the m-slashes (9) read the inside.

Durch diese Formgebung blelben bel einem aufgenommenen wälzlager zwlschen Walzlager und Lageraufnahmering zwei winklige Hohlräume (11).Due to this shape, the roller bearings appear between the bearings Rolling bearing and bearing receiving ring two angled cavities (11).

Die Kukgellaufbahnben konnon also beim Lauf einer beiastelten Kugel von Laufbahnmitte zu Laufbannanschlag etwas einfodern.So the Kukgellaufbahnben could run a tinkered ball Demand something from the middle of the track to the stop.

Durch Rüttein jund dNeigung der Antriebwelle zum Laufbannanschlag gelangen und bei einer Axlalbewegung der Welle micht rellen, sondern geschoben werden uknd sbflachen.By jolting and inclining the drive shaft towards the treadmill stop reach and with an axial movement of the shaft micht rellen, but are pushed uknd sbflachen.

Die kkugelin aus hartem Werkstoff oder wenig elastisen mit harter Oberfläche stüzen sich gegenüber ihrer laufoahn in einem Hohizylinder (3) ab. Zum Schutz gegen Eindringen und Berklemmen von Fremdxörpjeru aus Fanrtrichtung ist die Lagera@stützung mit einer elastischen Behleudescheibe (13) versehen, die mitrotierend auf den welienzabfen gesteckt ist.The ball is made of hard material or a little elastic with a hard one Surfaces are supported in a hollow cylinder (3) in relation to their running path. To the Protection against penetration and jamming of foreign bodies from the direction of the fan is the Lagera @ support provided with an elastic Behleudescheibe (13), which rotates with it is stuck on the welienzabfen.
