  Verfahren zum Einfüllen scheibenförmiger Rollen in Rollenlager. 



   Zum Einbringen der Rollen in ein Rollenlager werden verschiedene Verfahren angewendet. Es werden besondere Einfüllungsöffnungen benutzt, wie bei Kugellagern üblich. Dadurch wird indessen die Gleichförmigkeit der Laufrillen beeinträchtigt. Es werden auch die Laufringe exzentrisch zueinander gestellt, um so viele Rollen einzuführen, die zwischen der exzentrisch gestellten Laufringe eintreten können und sodann die Rollen über den ganzen Umfang der
Laufringe zu verteilen. Dabei kann indessen nur eine ziemlich beschränkte Anzahl von
Rollen eingeführt werden. Es ist ferner bei verhältnismässig kurzen, sogenannten scheiben- förmigen Rollen vorgeschlagen worden, diese in umgekippter Stellung einzuführen, so dass die normale Umdrehungsachse der einzelnen Rollen etwa parallel mit einem Halbmesser des
Lagers liegt, und sodann die Rollen in ihre Arbeitslage zu drehen.

   Beim letzterwähnten
Verfahren wird indessen das Material sowohl der Rollen wie der Lagerringe verhältnismässig grossen Beanspruchungen unterworfen, und damit die Rollen und Laufringe dabei nicht dauernde
Formveränderung erleiden, dürfen die Länge und die Breite der Rollen gewisse Grenzen nicht überschreiten. 



   Die vorliegende Erfindung bezieht sich auf ein Verfahren zum Einbringen scheiben- förmiger, d. h.   verhältnissmässig   kurzer oder dünner Rollen in ein Rollenlager, das mit Rillen in beiden Laufringen versehen ist. Bei diesem Verfahren werden sämtliche der oben erwähnten Übelstände beseitigt und ausserdem erreicht, dass unter gewissen Verhältnissen die grösstmögliche Anzahl Rollen in das Lager eingeführt werden kann, ohne dass das Material dabei irgendeiner schädlichen Beanspruchung ausgesetzt wird. 



   Die Erfindung besteht im Wesentlichen darin, dass die Rollen, senkrecht zu ihrer normalen Arbeitslage gedreht mit derjenigen Symmetrieebene, die senkrecht zu der Umdrehungsachse der Rolle steht oder ungefähr in einer zur Lagerachse radialen Ebene liegend, in das Lager eingeführt werden, während die beiden Laufringe exzentrisch gegeneinander gehalten werden. Die Rollen werden hierbei dicht aneinandergedrängt und sodann die Laufringe in ihre konzentrische Arbeitslage gebracht, die Rollen in den Laufrillen verschoben, über den ganzen Umriss verteilt und darauf um   900   gedreht, worauf das Lager fertig zusammengestellt ist. 



   In der Zeichnung wird das Einführungsverfahren schematisch dargestellt, und zwar für ein einreihiges Rollenlager. 



   Fig. i stellt eine Seitenansicht des Lagers bei Beginn des Zusammensetzens dar. Fig. 2 zeigt das Lager mit sämtlichen Rollen an ihrem Platz aber noch nicht in ihre Arbeitslage gedreht. Fig. 3 zeigt den Querschnitt eines Teiles des Lagers. 



   Fig. 4 zeigt eine Seitenansicht des Lagers mit endgültig in ihre Arbeitslage eingestellten Rollen. 



   Der Innenring ist in der Zeichnung mit a, der Aussenring mit b und die scheibenförmigen Rollen mit c bezeichnet. Fig. i zeigt, wie während der Innenring a in exzentrischer Lage zu dem Aussenring b gehalten wird, die Rolle c'in die Laufrille eingeführt wird, indem sie zwischen die Ränder der beiden Ringe gesteckt wird. 



   Fig, 2 zeigt, wie sämtliche Rollen in den oberen halbkreisförmigen Teil des Zwischenraumes zwischen den beiden Laufringen untergebracht, rechtwinklig zu ihrer normalen 

 <Desc/Clms Page number 2> 

 Arbeitslage gedreht und dicht aneinandergeschoben sind. Der Innenring   a   ist hier in konzentrischer Lage gegenüber dem Aussenring b gezeigt, was möglich wird, sobald alle Rollen in die Laufrillen eingelegt sind. Fig. 4 zeigt, wie nachdem die Rollen längs des ganzen Lagerumfanges verteilt und in Arbeitslage herumgedreht worden sind. 



   Um nach dieser Erfindung so viele Rollen wie das Lager überhaupt enthalten kann, einbringen zu können, darf die Breite der Rollen, wie aus Fig. 2 ersichtlich ist, nur so gross sein, dass   sämtliche   Rollen, rechtwinkelig zur normalen Arbeitslage gedreht und dicht zusammengedrängt, nicht mehr als den halben Umfang des Innenlaufringes einnehmen.

  Method of filling disc-shaped rollers in roller bearings.



   Various methods are used to introduce the rollers into a roller bearing. Special filling openings are used, as is usual with ball bearings. However, this deteriorates the uniformity of the raceway grooves. The races are also set eccentrically to each other in order to introduce as many roles that can occur between the eccentrically set races and then the rollers over the entire circumference of the
Distribute races. However, only a fairly limited number of
Roles are introduced. In the case of relatively short, so-called disk-shaped rollers, it has also been proposed to introduce them in the overturned position so that the normal axis of rotation of the individual rollers is approximately parallel with a radius of the
Bearing, and then turn the rollers into their working position.

   The last one mentioned
In the process, however, the material of both the rollers and the bearing rings is subjected to relatively great stresses, and thus the rollers and races are not subjected to permanent loads
If the shape changes, the length and width of the rolls must not exceed certain limits.



   The present invention relates to a method for introducing disc-shaped, i. H. relatively short or thin rollers in a roller bearing that is provided with grooves in both races. This method eliminates all of the above-mentioned inconveniences and also ensures that, under certain conditions, the greatest possible number of rollers can be inserted into the bearing without the material being exposed to any harmful stress.



   The invention essentially consists in that the rollers, rotated perpendicular to their normal working position with that plane of symmetry which is perpendicular to the axis of rotation of the roller or lying approximately in a plane radial to the bearing axis, are inserted into the bearing, while the two races are eccentric are held against each other. The rollers are pressed close together and then the races are brought into their concentric working position, the rollers are moved in the grooves, distributed over the entire outline and then rotated by 900, whereupon the bearing is assembled.



   In the drawing, the introduction process is shown schematically for a single-row roller bearing.



   Fig. I shows a side view of the bearing at the start of assembly. Fig. 2 shows the bearing with all the rollers in place but not yet rotated into their working position. Fig. 3 shows the cross section of part of the bearing.



   4 shows a side view of the bearing with the rollers finally set in their working position.



   The inner ring is designated in the drawing with a, the outer ring with b and the disc-shaped rollers with c. FIG. I shows how, while the inner ring a is held in an eccentric position with respect to the outer ring b, the roller c 'is inserted into the running groove by being inserted between the edges of the two rings.



   Figure 2 shows how all the rollers are housed in the upper semicircular part of the space between the two races, perpendicular to their normal

 <Desc / Clms Page number 2>

 Working position are rotated and pushed close together. The inner ring a is shown here in a concentric position with respect to the outer ring b, which becomes possible as soon as all the rollers are inserted into the running grooves. Fig. 4 shows how after the rollers have been distributed along the entire circumference of the bearing and turned around in the working position.



   In order to be able to bring in as many rolls as the bearing can contain according to this invention, the width of the rolls, as can be seen from FIG. 2, may only be so large that all rolls, rotated at right angles to the normal working position and densely packed, do not occupy more than half the circumference of the inner race.
