ohne gleitende Reibung rollen.roll without sliding friction.
Patentirt im Deutschen Reiche vom 11. Juli 1897 ab.Patented in the German Empire on July 11, 1897.
Gegenstand der Erfindung ist ein Rollenlager, bei welchem die gleitende Reibung dadurch verhindert ist, dafs die Zapfen der zwischen den Tragrollen angeordneten Zwischenrollen so gelagert sind, dafs dieselben auch ohne gleitende Reibung rollen, und dafs auch die Reibung an den Stirnflächen der Lagertheile eine rollende ist.The invention relates to a roller bearing, in which the sliding friction thereby it is prevented that the pins of the intermediate rollers arranged between the support rollers are so mounted that they roll without sliding friction, and that too the friction on the end faces of the bearing parts is rolling.
Auf der beiliegenden Zeichnung veranschaulicht Fig. ι einen Längenschnitt und Fig. 2 einen Querschnitt durch ein gemäfs der Erfindung construirtes Rollenlager.On the accompanying drawing, FIG. 1 illustrates a longitudinal section and FIG. 2 a cross section through a roller bearing constructed according to the invention.
Dasselbe besteht aus dem feststehenden Theile α und dem rotirenden Theile b. Selbstverständlich kann die Anordnung auch umgekehrt sein, so dafs α rotirt, während b feststeht. It consists of the fixed part α and the rotating part b. Of course, the arrangement can also be reversed, so that α rotates while b is fixed.
Schon das amerikanische Patent Nr. 462744 weist Zwischenrollen oder Haltrollen zwischen den Tragrollen auf, welche sich gegenseitig berühren. Während aber bei dem genannten amerikanischen Patente die grofsen Durchmesser der Zwischenrollen die kleinen Umfange der Tragrollen berühren und die Zapfen der Zwischenrollen in besonderen Haltescheiben gelagert sind, ist beim Gegenstande dieser Erfindung zur Verhinderung der hierdurch bedingten gleitenden Reibung der Zapfen in den Haltescheiben und der Rollen an den Stirnflächen folgende Anordnung getroffen:The American patent no. 462744 already has intermediate rollers or holding rollers between the support rollers, which touch each other. But while with the said American patents the large diameters of the intermediate rollers the small sizes of the support rollers and the pins of the intermediate rollers in special retaining washers are stored, is the subject of this invention to prevent the resulting sliding friction of the pins in the retaining washers and the rollers on the end faces the following arrangement is made:
Der Theil α besitzt zwei flantschartige Erweiterungen a1, in welche eine ringförmige Nuth c eingedreht ist. Auf der inneren, der Rotationsachse am nächsten liegenden Fläche der Nuth c ruhen die Zapfen d von Rollen e, welche zwischen dem feststehenden und dem rotirenden. Theil eingeschaltet sind. Abwechselnd mit diesen Rollen sind Rollen f angeordnet, welche die grofsen Umfange der Tragrollen berühren, und welche mit ihren Zapfen nicht in Haltescheiben gelagert sind, sondern frei auf der äufseren Fläche c2 der Nuth c liegen.The part α has two flange-like extensions a 1 , into which an annular groove c is screwed. On the inner surface of the groove c which is closest to the axis of rotation, the pins d of rollers e, which lie between the stationary and the rotating one, rest. Part are switched on. Alternating with these rollers are rollers f which touch the largest circumference of the support rollers and which are not mounted with their pins in holding disks, but lie freely on the outer surface c 2 of the groove c.
Die seitlichen Abrundungen an den Stirnflächen der Rollen, sowie des Zapfens und der Lagerhöhlung sind so gewählt, dafs die Berührung der genannten Stirnflächen nach Kreisen erfolgt, welche in der gedachten Fortsetzung der sich abrollenden Mantelflächen liegen. Der Deutlichkeit halber ist in Fig. 1 in der oberen Hälfte nur eine Rolle e und in der unteren Hälfte nur eine Rolle f gezeigt. Die gegenseitige Lage dieser Rolle geht aus Fig. 2 deutlich hervor.The lateral roundings on the end faces of the rollers, as well as the journal and the bearing cavity, are chosen so that the contact of the said end faces takes place in circles which are in the imaginary continuation of the rolling lateral surfaces. For the sake of clarity, only one roller e is shown in the upper half of FIG. 1 and only one roller f is shown in the lower half. The mutual position of these roles is shown clearly in FIG.
■Wenn nun der äufsere und der innere Durchmesser der Nuth c und ferner die Durchmesser der Rollen e und f und ihrer Zapfen d und g im Verhältnifs zu dem Durchmesser des Theiles b so gewählt werden, dafs die Rollen, während sie bezw. ihre Zapfen einmal auf den Laufflächen abrollen, sich gleichzeitig auch auf den benachbarten Rollen einmal abrollen, so ist ersichtlich, dafs nur rollende, nicht aber gleitende Reibung auftritt. Eine derartige Wahl der Durchmesser ist bei der beschriebenen Anordnung leicht möglich. Es ist daher ein Rollenlager geschaffen, welches sich infolge der Vermeidung jeder gleitendenIf now the outer and inner diameter of the groove c and also the diameter of the rollers e and f and their journals d and g are chosen in relation to the diameter of the part b so that the rollers, while they respectively. If their pegs roll once on the running surfaces and at the same time roll once on the neighboring rollers, it can be seen that there is only rolling friction, not sliding friction. Such a choice of the diameter is easily possible with the arrangement described. It is therefore a roller bearing created, which as a result of avoiding any sliding
Reibung sowohl für rotirende Maschineritheile als auch besonders als Achsenlager für Eisenbahnfahrzeuge und dergl. eignet.Friction both for rotating machine parts and especially as axle bearings for railroad vehicles and the like.
Unter denselben Verhältnissen ergeben kegelförmige Rollen mit entsprechenden Laufflächen, deren Erzeugende nach einer gemeinsamen, in der Achse liegenden Spitze gerichtet sind, eine Stützlagerform ohne gleitende Reibung.Under the same conditions, tapered rollers with corresponding running surfaces result in whose generatrices are directed towards a common, in-axis tip, a Support bearing form without sliding friction.
