Rollenlager.Roller bearings.
Die Erfindung betrifft eine Vervollkommnung an Wälzrollenlagern, die für alle· Arten solcher Lager, wie Steh-, Stütz- und Halslager, Wagenachsbüchsen, Pfostenfufslager und dergl. anwendbar ist.The invention relates to an improvement in rolling roller bearings that are used for all types of such Bearings, such as pedestal, support and neck bearings, wagon axle bushes, post foot bearings and the like. Applicable is.
Der Neuerung liegt der Zweck zu Grunde, so viel wie möglich den Kraftverlust auszuschliefsen, der durch reibende Berührung der Wälzrollen unter sich längs ihren Erzeugungsgeraden entstehen kann.The purpose of the innovation is to exclude the loss of strength as much as possible, by frictional contact between the rollers along the straight lines of their generation can arise.

Um den Erfolg möglichster Reibungsverminderung in Hinsicht auf die Berührung der Rollkörper unter sich zu erzielen, müssen letztere, die zwischen den Zapfen und Lagerlaufflä'chen in bekannter Weise eingeschaltet werden, daran gehindert werden, dafs sie sich längs ihrer Seiten berühren. Dies wird durch folgende Einrichtung gemäfs der Erfindung erreicht.In order to achieve the greatest possible reduction in friction with regard to the touch of the To achieve rolling bodies among themselves, the latter must be between the journals and bearing running surfaces are switched on in a known manner, are prevented from touching along their sides. This is going through achieved the following device according to the invention.
Mit Bezug auf die Anordnung nach Fig. 1, wo die cylindrisch gestalteten Wälzrollen a zwischen der cylindrischen Aufsenfläche des Zapfens oder der Welle Z und dem festen, cylindrisch ausgebohrten Gegenlager Y laufen, zeigt sich jede Rolle α an beiden Enden mit einem conaxialen Zapfen al von sehr schwachem Durchmesser versehen; auf diesem Zapfen ist mit schwacher Reibung eine kreisrunde Scheibe b aufgesteckt, die einen gröfseren Durchmesser als die Rolle α haben soll. Wie aus Fig. 1 und 2 (und beiläufig aus Fig. 3 a) ersichtlich, giebt man den Naben der Scheiben b in jedem Falle eine derartige Form, dafs sie nicht erheblich an den Stirnflächen der Rollen und an den Widerlagsflaritschen Y1 des Lagers reiben.With reference to the arrangement according to FIG. 1, where the cylindrically shaped rolling rollers a run between the cylindrical outer surface of the pin or the shaft Z and the fixed, cylindrically bored counter bearing Y , each roller α shows itself at both ends with a conaxial pin a l of very small diameter; A circular disk b is placed on this pin with low friction, which should have a larger diameter than the roller α . As can be seen from FIGS. 1 and 2 (and incidentally from FIG. 3a), the hubs of the disks b are always given a shape such that they do not rub considerably on the end faces of the rollers and on the abutment flanges Y 1 of the bearing .
Während sich sp, wie aus Fig. 2 ersichtlich, die Rollen α selbst nirgends berühren können, stützen sich nur die Scheiben b b mit ihren Umfangen gegen einander, und zwar auch nur in einem Punkte, wofür durch eine entsprechend ballige Form des Randwulstes . der Scheibe gesorgt ist.While sp, as can be seen from Fig. 2, the rollers α themselves cannot touch anywhere, only the disks bb are supported with their circumferences against each other, and only at one point, for which a correspondingly spherical shape of the edge bead. the disc is taken care of.
Die einzige Gleitungsreibung, die bei diesem System auftreten kann, macht sich demgemäfs zwischen den Rollenzapfen a1 a1 und den Scheiben b b bemerkbar; da nun genannteThe only sliding friction that can occur with this system is accordingly noticeable between the roller journals a 1 a 1 and the disks bb ; there now mentioned
Zapfen sehr dünn sind und ferner der Druck einer Scheibe gegen die benachbarte äufserst gering ist, weil diese Scheiben eben nur die Rollen α α aus einander halten, nicht aber deren Zapfen oder die Welle Z stutzen sollen, so folgt hieraus, dafs die Reibung zwischen den Rollenzapfen a1 und den Scheiben b beinahe gleich Null ist.Pins are very thin and, furthermore, the pressure of one disk against the neighboring one is extremely low, because these disks are only supposed to hold the rollers α apart from each other, but not their pins or the shaft Z , it follows from this that the friction between the Roller pin a 1 and the disks b is almost zero.
Die Scheiben b b müssen natürlich mit ihren Umfangen frei laufen; damit sie weder an dem Lager Y noch an dem Zapfen Z anstofsen, sind an letzteren die Rinnen yl und ^1 ausgedreht (Fig. i).The disks bb must of course run freely with their circumference; So that they do not touch either the bearing Y or the pin Z , the grooves y 1 and ^ 1 are turned out on the latter (Fig. i).
Sofern das Lagergehäuse am unteren Theil als Schmierölbehälter ausgebildet ist und Schmierkanäle zu den Wälzflächen der Rollen α führen, bewirken diese Rollen bei ihrer Umlaufbewegung von selbst eine ausreichende und wirksame Schmierung des Lagers.If the bearing housing is designed as a lubricating oil container on the lower part and lubricating channels lead to the rolling surfaces of the rollers α , these rollers automatically provide sufficient and effective lubrication of the bearing when they rotate.
In dem Falle der Ausrüstung von Fufs- oder Unterlagern gemäfs der Erfindung, welche Fig. 3 darstellt, werden Rollen αλ in Form von abgestumpften Kegeln angewendet.In the case of equipping feet or sub-bearings according to the invention, which is shown in FIG. 3, rollers α λ in the form of truncated cones are used.
Auch hier sind, wie in der Ausführung nach Fig. i, an den Stirnenden der Rollen auf Zapfen derselben lose drehbare Scheiben bx (Fig. 3 a) angebracht, die ausschliefslich den Zweck erfüllen, die Rollen unter sich getrennt zu halten, um die geringste Reibung darzubieten. Are also here, as in the embodiment of FIG. I, b at the ends of the rollers to journal the same loosely rotatable discs x (Fig. 3 a) is attached, which exclusively serve the purpose of keeping the rolls isolated among them, the to offer the least amount of friction.
Fig. 4 stellt den Schnitt eines Stehlagers für eine einem Enddruck ausgesetzte durchgehende Welle dar. Der aufzunehmende Druck ist in der Richtung des Pfeiles χ angenommen. Diese Anordnung ist lediglich eine Combination aus den vorher bezeichneten zwei Lagerausführungen. Fig. 4 shows the section of a pillow block bearing for a through shaft exposed to a final pressure. The pressure to be absorbed is assumed in the direction of the arrow χ. This arrangement is only a combination of the two bearing designs described above.
Die kegelförmigen Stützrollen C2 (Fig. 4a) laufen zwischen einem Flantsch oder Bund ^2 der Welle Z und einem von zwei Ringstegen eingefafsten Flantsch y2 der Lagerbüchse Y. Die cylindrischen Rollen a2 sind angeordnet und eingerichtet wie bei dem gewöhnlichen Lager (Fig. 1). Die Schmierung vollzieht sich vermöge des Oelzutritts zu den Rollen und den für sich drehbaren Rollenkopfscheiben durch die Umlaufbewegung dieser Theile von selbst.The conical support rollers C 2 (Fig. 4a) running between a Flantsch or collar ^ 2 of the shaft Z and a eingefafsten of two annular webs Flantsch y 2 of the bearing bush Y. The cylindrical rollers a 2 are arranged and configured such as (in the ordinary storage FIG . 1). The lubrication takes place automatically by virtue of the oil access to the rollers and the rotating roller head disks through the orbital movement of these parts.
Die Lagerconstruction nach Fig. 1 läfst erkennen, dafs sich der Zapfen oder die Welle Z, die bei f1^1 mit Rinnen versehen ist, infolge Wärmebeeinflussung oder aus anderen Gründen ausdehnen, zusammenziehen oder verkrümmen kann, ohne die gute Wirkung des Rollenlagers zu beeinträchtigen.The bearing construction according to Fig. 1 reveals that the pin or the shaft Z, which is provided with grooves at f 1 ^ 1 , can expand, contract or bend as a result of the influence of heat or for other reasons without impairing the good effect of the roller bearing .
Es läfst sich die neue Einrichtung des Rollenlagers behufs Ausschliefsung der gegenseitigen Berührung der Rollen allen möglichen Lagerconstructionen anpassen, ohne von dem Prinrip der Erfindung abzuweichen.The new arrangement of the roller bearing for the purpose of excluding the mutual Touching the rollers to adapt to all possible bearing constructions without relying on the principle deviate from the invention.
