Description
Rollenlager. Gegenstand der Erfindung ist ein Rollen lager mit aus einem Stück bestehenden Rollen und Laufringen mit krummem Rollbahnprofil. Gemäss der Erfindung liegen die Rollen in der Mitte am einen Laufring und an den Enden am andern Laufring an, zwecks weicher Auf nahme von Überlastungen und Stössen.
In der beiliegenden Zeichnung ist der Er findungsgegenstand in einigen Ausführungs beispielen dargestellt, und zwar zeigen die Abb. 1 und 2 Rollenlager im Schnitt und Abb. 3 und 4 eine Rolle.
Mit 1 ist der äussere Laufring, mit 2 der innere Laufring und mit 3 sind die Rollen be zeichnet. 4 und 5 sind die Berührungspunkte und 6 Schulternder Laufringe.
In Abb. 1 ist die Rolle 3 von zylindrischer Form; die Rollenfläche des äussern Lauf ringes 1 ist schwach bullig und die Rolle 3 be rührt dieselbe bei Punkt 5. Die Rollbahn des innern Laufringes 2 hat ein doppelwelliges Profil und berührt die Rolle 3 an ihren beiden Enden bei den Punkten 4. Die Berührungs punkte 4 und 5 sind versetzt, die Rolle 3 ist bei radialem Druck auf Biegung beansprucht und federt etwas durch, wie Abb. 1 durch eine gestrichelte Linie andeutet. Infolgedessen werden Überlastungen oder Druckstösse weich aufgenommen.
In Abb. 2 ist die Rolle 3 nur in ihrer Mitte zylindrisch und an beiden Enden ge wölbt kegelig ausgeführt. Die Enden könnten aber auch geradlinig kegelig oder kugelig sein. Die Rollenfläche des innern Laufringes 2 ist ballig und mit Schultern 6 versehen, die eine Bewegung der Rollen 3 in der Axenrichtung verhindern. Der äussere Laufring 1 hat eine kugelige Rollenfläche, deren Mittelpunkt auf der Axe des Lagers ist. Die Berührungs punkte 4 und 5 sind durch Pfeile kenntlich gemacht.
Inder Abb. 3 und 5 ist je eine als Schrau benfeder ausgebildete Rolle für die Rollen lager gemäss den Abb. 1. und 2 gezeichnet, welche eine höhere elastische Durchbiegung besitzen. Bei den bekannten Federrollen wird die Federwirkung im Durchmesser hier in der Längsrichtung ausgenützt. Die Rollen nach Abb. 2 und 4 sind in ihrer Axrichtung nicht nur durch die Schultern 6, sondern auch durch die Konizität der gewölbten Enden ge halten, so dass das Rollenlager gemäss Abb. 2 einen Druck in der axialen Richtung aufneh men kann. Ferner ist bei diesem Lager infolge der kugeligen Rollenfläche des äussern Lauf ringes eine Schrägstellung des innern Lauf ringes und der Rollen zum äussern Laufringe zulässig, was bei Durchbiegungen und Feh lern im Einbau eine selbsttätige Einstellung des Lagers ergibt.
Roller bearings. The invention relates to a roller bearing with one-piece rollers and races with a curved runway profile. According to the invention, the rollers lie in the middle on one raceway and at the ends on the other raceway, for the purpose of softer on acceptance of overloads and shocks.
In the accompanying drawing, the subject of the invention is shown in some execution examples, namely Figs. 1 and 2 roller bearings in section and Fig. 3 and 4 show a roller.
With 1 is the outer race, with 2 the inner race and with 3 the roles are be distinguished. 4 and 5 are the points of contact and 6 shoulders of the races.
In Fig. 1 the roller 3 is cylindrical in shape; the roller surface of the outer race ring 1 is weakly beefy and the role 3 be touches the same at point 5. The runway of the inner race 2 has a double-corrugated profile and touches the roller 3 at both ends at points 4. The points of contact 4 and 5 are offset, the roller 3 is subjected to bending under radial pressure and bends slightly, as indicated in Fig. 1 by a dashed line. As a result, overloads or pressure surges are gently absorbed.
In Fig. 2, the roller 3 is cylindrical only in its center and arched conical ge at both ends. The ends could also be conical or spherical in a straight line. The roller surface of the inner race 2 is crowned and provided with shoulders 6 which prevent the rollers 3 from moving in the axial direction. The outer race 1 has a spherical roller surface, the center of which is on the axis of the bearing. The points of contact 4 and 5 are indicated by arrows.
In Fig. 3 and 5 each is a roller designed as a screw benfeder for the roller bearings shown in Figs. 1. and 2 drawn, which have a higher elastic deflection. In the known spring rollers, the spring action in the diameter is used here in the longitudinal direction. The rollers according to Fig. 2 and 4 are held in their Axrichtung not only by the shoulders 6, but also by the conicity of the curved ends ge, so that the roller bearing according to Fig. 2 can absorb a pressure in the axial direction. Furthermore, due to the spherical roller surface of the outer race ring, an inclined position of the inner race ring and the rollers to the outer races is permitted in this camp, which results in an automatic setting of the bearing in the event of deflections and errors during installation.
