High speed bearing has an outer sleeve with an outer race and a shaft with an inner race and two rows of balls with a cage, and has a shaft (1) dia (d) increased between the first race (2) and the second race (3) by a ratio of d/D = 0.6 to 0.95, where (D) is the dia of the thickened section of the shaft (1). The gap (a) between the end face of the shaft (1) and the first race (2) is shortened by a ratio of a/I = 0.40 to 0.57, where (1) is the gap between the first (2) and second (3) race. The shaft (1) for the inner races (2,3) is pref within the sleeve (4) for the outer race. The balls (5) of the bearing are contained within a cage (7), in two rows. Disc covers (6) are at both ends. The shaft (1) dia is increased between the two races (2,3). ADVANTAGE - The structure increases the dynamic rigidity and the working life of the bearing, and allows it to function at higher speeds than 8 x 10 power 4/min.

Description

Die Erfindung betrifft ein Hochgeschwindigkeitslager, das vor allem für die Lagerung von Spinnrotoren bei Textilmaschinen bestimmt ist.The invention relates to a high-speed bearing, especially for the storage of spinning rotors Textile machines is determined.

Bei der bisherigen Wälzlagerung in Feinspinnmaschinen wird ein spezielles Kugellager verwendet, das aus einer äußeren Hülse und einer Welle mit konstantem Durchmesser besteht. In beiden Teilen sind Laufbahnen hergestellt, in denen durch Käfige geführte Rollkörper angebracht sind. Das Lager ist mit Randdeckscheiben versehen. Die Schmierung des Lagers wird durch eine Konsistenzfett-Innenfüllung gewährleistet.With the previous roller bearing in fine spinning machines a special ball bearing is used, which consists of a outer sleeve and a shaft with constant Diameter exists. There are careers in both parts manufactured in which rolling elements guided by cages are attached. The camp is with edge cover plates Mistake. The bearing is lubricated by a Consistency grease inner filling guaranteed.

Diese Konstruktionslösung hat den Nachteil, daß bei einer Drehzahl höher als 8 · 104 min.-1 eine nicht zu überschreitende Grenze infolge der ungenügenden dynamischen Steifigkeit der Welle vorhanden ist, die durch die Masse des Spinnrotors und die Steifigkeit der Welle bestimmt ist. Bei einer gegebenen Größe des Spinnrotors hängt die dynamische Steifigkeit von der Steifigkeit der Welle ab, die durch den Wellendurchmesser und seine Auskragung mit dem Spinnrotor bestimmt ist. Vom Standpunkt einer ausreichenden Schmierung mittels der Innenfüllung von Konsistenzfett wird bei hohen Drehzahlen eine Wellengröße mit 9 mm-Durchmesser als Grenzgröße betrachtet. Bei einer höheren Drehzahl als 8 · 104 min.-1 kommt es infolge der ungenügenden dynamischen Steifigkeit zu einem instabilen Lauf des Lagers, der mit erhöhter Geräuschbildung und Auftreten von übermäßigen auf das Lager wirkenden Kräften, die zur Verminderung der Lagerlebensdauer führen, verbunden ist.This design solution has the disadvantage that at a speed higher than 8 · 10 4 min. -1 there is a limit that cannot be exceeded due to the insufficient dynamic stiffness of the shaft, which is determined by the mass of the spinning rotor and the stiffness of the shaft. For a given size of the spinning rotor, the dynamic stiffness depends on the stiffness of the shaft, which is determined by the shaft diameter and its projection with the spinning rotor. From the standpoint of sufficient lubrication by means of the inner filling of consistency grease, a shaft size with a 9 mm diameter is considered as the limit size at high speeds. At a speed higher than 8 · 10 4 min. -1 due to the insufficient dynamic rigidity, the bearing runs unstably, which is associated with increased noise and the occurrence of excessive forces acting on the bearing, which reduce the bearing life.

Die Erfindung vermindert die angeführten Nachteile. Es ist die Aufgabe der Erfindung, mit einfachen Mitteln die dynamische Steifigkeit und damit die Lebensdauer des Lagers zu erhöhen und das Lager für noch höhere Drehzahlen geeignet zu machen.The invention alleviates the disadvantages mentioned. It is the object of the invention with simple means the dynamic rigidity and thus the service life of the camp to increase and the camp for even higher ones To make speeds suitable.

Das Lager besteht aus einer äußeren Hülse mit Außenlaufbahnen, aus einer Welle mit Innenlaufbahnen und aus zwei Reihen durch Käfige geführter Rollkörper, und ist mit Randdeckscheiben versehen.The bearing consists of an outer sleeve with External raceways, from a shaft with inner raceways and from two rows of rolling elements guided by cages, and is provided with edge cover plates.

Die Erfindung besteht darin, daß die Welle mit dem Durchmesser d zwischen der ersten und der zweiten Laufbahn im Verhältnis von 0,6 bis 0,95 verstärkt ist, wobei D den Durchmesser des verstärkten Wellenteils bezeichnet. Der Abstand a der Wellenstirn­ fläche von der ersten Laufbahn ist im Verhältnis von 0,40 bis 0,57 verkürzt, wobei 1 der Abstand zwischen der ersten und der zweiten Laufbahn ist. The invention is that the shaft with the Diameter d between the first and the second Career strengthened in the ratio of 0.6 to 0.95 where D is the diameter of the reinforced Designated part of the shaft. The distance a of the wave front The area of the first career is in the ratio of 0.40 to 0.57 shortened, where 1 is the distance between the first and second careers.  

Der Vorteil des Hochgeschwindigkeitslagers gemäß der Erfindung besteht darin, daß durch die Wellenverstär­ kung sowie durch die Verkürzung des Abstands der Wellenstirnfläche von der ersten Laufbahn die dynamische Steifigkeit und dadurch auch die Lebensdauer des Lagers erhöht wird.The advantage of the high speed bearing according to the Invention is that by the wave amplifier kung and by shortening the distance of the The end face of the shaft from the first race dynamic rigidity and therefore also the service life of the camp is increased.
