Description
Durch die deutschen Patente 509 315 und 965 671 sowie durch das schweizerische Patent 87 615 sind Zylinderrollenlager bekanntgeworden, bei denen durch axiale Krafteinwirkung die Lagerdurchmesser zwecks Regulierung des Rollspieles verkleinert bzw. vergrößert werden können. Während nach den Patenten 509315 und 87 615 die einstellbaren Laufringe elastische Federbänder darstellen, welche in einer Kegelbohrung bzw. auf einem Kegel verschoben werden, weist der stellbare Laufring nach Patent 965 671 innere und.äußere Ausnehmungen auf, die gegenseitig versetzt angeordnet sind und dadurch ihm die für die Stellbarkeit notwendige Elastizität verleihen. Alle drei oben angeführten Ausführungen haben gemeinsam, daß das Rollspiel wohl in radialer Richtung, nicht aber auch zugleich in axialer Richtung geregelt werden kann. Sie können nur Belastungen in radialer Richtung, nicht aber in axialer Richtung aufnehmen.By the German patents 509 315 and 965 671 as well as by the Swiss patent 87 615 are Cylindrical roller bearings become known, in which the bearing diameter for the purpose of axial force Regulation of the role play can be reduced or enlarged. While after the patents 509315 and 87 615 the adjustable races represent elastic spring bands, which in a tapered bore or moved on a cone, the adjustable race according to patent 965 671 inner and outer recesses, which are mutually offset and thereby give him the for the Lend adjustability the necessary elasticity. All three of the above statements have in common, that the rolling game can be regulated in the radial direction, but not at the same time in the axial direction can. You can only absorb loads in the radial direction, but not in the axial direction.
Die Erfindung bezieht sich auf die Ausbildung von Wälzlagern, deren Rollspiel in radialer und zugleich in axialer Richtung regelbar ist und ebenso Kräfte in radialer als auch in axialer Richtung aufnehmen kann, insbesondere auf Kugellager, bei denen mindestens ein Laufring als elastisches Glied ausgebildet ist, indem dieser zwischen den Laufbahnen längs seines inneren und äußeren Umfanges mit gegeneinander versetzten radialen Ausnehmungen versehen ist, durch die tellerfederartige Wände gebildet werden, so daß bei Einwirkung einer axialen Kraft die Laufbahnen in axialer Richtung sich einander nähern und das Rollspiel beseitigt werden kann.The invention relates to the formation of rolling bearings, their rolling play in radial and at the same time can be regulated in the axial direction and can also absorb forces in the radial as well as in the axial direction, in particular on ball bearings in which at least one race is designed as an elastic member by this between the raceways along its inner and outer circumference with offset from one another radial recesses are formed by the plate spring-like walls, so that upon action an axial force, the raceways approach each other in the axial direction and the rolling play is eliminated can be.
Das erfindungsgemäße Kugellager zeichnet sich den bekannten Ausführungen gegenüber dadurch aus, daß sein stellbarer Laufring ein einfaches und ungeteiltes Drehteil mit zylindrischer Außenfläche darstellt, der beim Einbau mit kleinem Paßspiel in die Gehäusebohrung eingeschoben wird, so daß beim Anziehen eines Gewinderinges das Rollspiel zwischen den Kugeln und den Laufbahnen geregelt werden kann. Da die Regulierung des Rollspieles im Stillstand oder aber während des Laufes geschehen kann, ist eine leichte Anpassung der Lager an den jeweiligen Belastungsfall gegeben.The ball bearing according to the invention is distinguished from the known designs in that its adjustable race is a simple and undivided rotating part with a cylindrical outer surface, the is inserted into the housing bore with a small clearance when installing, so that when tightening a threaded ring, the rolling play between the balls and the raceways can be regulated. There The regulation of the role play can be done while standing still or while running, is one easy adjustment of the bearings to the respective load.
In der Zeichnung ist mit 1 das Gehäuse, mit 2 der stellbare Außenring, mit 3 die Spindel, mit 4 der innere Laufring, mit 5 der Gewindering, mit 6 ein Distanzrohr und mit 7 die kugelförmigen Rollkörper bezeichnet. Die obere Hälfte der Zeichnung zeigt den Laufring 2 in ungespanntem Zustand, also mit einigen Hundertstelmillimeter Rollspiel zwischen den Rollkörpern und den Laufbahnen. Die untere Hälfte dagegen zeigt denselben Laufring in gespanntem Zustand, d.h. mit jeglicher Spielbeseitigung zwischen den Rollkörpern und Laufbahnen.In the drawing, 1 is the housing, 2 is the adjustable outer ring, 3 is the spindle, 4 is the inner race, with 5 the threaded ring, with 6 a spacer tube and with 7 the spherical rolling element designated. The upper half of the drawing shows the raceway 2 in the untensioned state, so with some Hundredths of a millimeter of rolling play between the rolling elements and the raceways. The lower half, on the other hand shows the same race in tensioned condition, i.e. with any clearance between the rolling elements and raceways.

Der äußere Laufring 2 ist erfindungsgemäß an seiner Außenfläche mit einer radialen Ausnehmung und an seiner Innenfläche zwischen den Laufbahnen, um das Maß b axial versetzt zu der äußeren Ausnehmung, mit radialen Ausnehmungen9 versehen, so daß sich zwischen der äußeren Ausnehmung 8 und der inneren Ausnehmung 9 tellerfederartige Wände 10 und die Gelenkstellen 11 bilden. Wird nun der Gewindering 5 angezogen, so stützt sich der Laufring 2. an der Gehäuseanlagefläche 12 ab, es tritt eine tellerfederartige Verformung der Wände 10 und eine Längenänderung um das Maß a ein, d. h., die rechte Kugellaufbahn nähert sich der feststehenden linken Kugellaufbahn so lange, bis schließlich das Rollspiel beseitigt ist. Bei einer Lockerung des Gewinderinges 5 federt der Laufring 2 wieder um das Maß α zurück, so daß das ursprüngliche Rollspiel hergestellt ist. Toleranzschwankungen zwischen den Rollkörpern und Laufbahnen lassen sich dank der einfachen Verstellmöglichkeit mühelos beherrschen. According to the invention, the outer race ring 2 is provided on its outer surface with a radial recess and on its inner surface between the raceways, axially offset by the dimension b from the outer recess, with radial recesses 9, so that between the outer recess 8 and the inner recess 9 Form plate spring-like walls 10 and the hinge points 11. Now, when the ring nut 5 is tightened, then the thrust ring supports 2 on the housing bearing surface 12 on, it enters a plate-spring-like deformation of the walls 10 and a change in length by the dimension a, a, that is, the right ball track approaches the fixed left ball track so long until finally the roleplay is eliminated. When the threaded ring 5 is loosened, the race 2 springs back again by the amount α, so that the original rolling game is established. Tolerance fluctuations between the rolling elements and raceways can be easily controlled thanks to the simple adjustment option.
Während die Zeichnung nach Fig. 1 ein zweireihiges Kugellager mit stellbarem Außenlaufring zeigt, kann beispielsweise auch der Lageraußenring für ein einreihiges Kugellager nach Fig. 2, ein Pendelkugellager nach Fig. 3 oder aber ein Tonnenlager nach Fig. 4 oder aber anstatt der Lageraußenring der Lagerinnenring 4 oder aber beide in ähnlicher Weise einstellbar ausgeführt werden.While the drawing according to FIG. 1 shows a two-row ball bearing with an adjustable outer race, can for example also the bearing outer ring for a single-row ball bearing according to FIG. 2, a self-aligning ball bearing 3 or a barrel bearing according to FIG. 4 or, instead of the bearing outer ring, the bearing inner ring 4 or both can be made adjustable in a similar manner.
