  Verfahren zur Herstellung von Radiallagern 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 sichtlich, in jedem Quadranten der verlangte keilförmige Spielraum 11 zwischen Welle und Lagerschale, in dem das Schmieröl entsprechend komprimiert wird, so dass die Welle dann ohne metallische Berührung mit den Lagerteilen im Schmieröl schwimmt in diesem Beispiel ist nur im linken oberen Quadranten das Lagermetall 13 eingezeichnet, das nur über den engeren Teil des Lagerspieles ausgelegt ist. 



   Fig. 2 zeigt nun ein Radiallager mit vier symmetrisch angeordneten Lagerteilen 6,7, 8 und 9, welche jedoch gemäss dem zweiten oben beschriebenen Herstellungsverfahren bei ihrer Vorbearbeitung mit zwischen ihren Flanschen 10 eingelegten Distanzstreifen zusammengesetzt und zylindrisch ausgedreht wurden bei diesen Lagerteilen bildet also der Querschnitt der Laufflächen keinen vollen Viertelkreis mehr, sondern er ist nach Weglassung der Distanzstreifen um einige Winkelgrade verkürzt, so dass der Spielraum nunmehr in jedem Quadranten für sich in der Mitte am engsten und gegen beide Flanschen zu keilförmig erweitert ist ; hier sind alle vier Lagerteile auf einem peripheren Abschnitt mit Lagermetall 13 ausgekleidet.

   Es ist ohne weiteres ersichtlich, dass diese in Fig. 2 dargestellte Ausführungsform von Radiallagern ohne weiteres für beide Drehrichtungen der Welle A verwendet werden kann. 



   Das erfindungsgemässe Verfahren kann selbstverständlich ausser zur Herstellung der beispielsweise dargestellten vierteiligen Radiallager in gleicher Weise und mit dem gleichen Effekt auch für solche mit anderer Teilung der Lagerschalen verwendet werden. 



    PATENTANSPRÜCHE :    
1. Verfahren zur Herstellung von Radiallagern mit hydrodynamischer Schmierung-vorzugsweise für vertikale Wellen-, welche aus mehreren Lagerteilen mit kreiszylindrischen Laufflächen je exzentrisch zur Lagerachse zusammengesetzt sind, dadurch gekennzeichnet, dass ein mehrteiliges - vorzugsweise   vierteiliges - Lager   vorerst in zusammengesetztem Zustande zylindrisch auf einen gemeinsamen Innendurchmesser seiner Teile ausgedreht wird, der etwas grösser ist als der grösste zulässige Durchmesser der einzusetzenden Welle (A), wonach das Lager wieder zerlegt wird und schliesslich die untereinander gleichen Lagerteile mit ihren Laufflächen exzentrisch zusammengebaut werden.

  Process for the production of radial bearings
 EMI1.1
 

 <Desc / Clms Page number 2>

 Obviously, in each quadrant the required wedge-shaped clearance 11 between the shaft and bearing shell, in which the lubricating oil is compressed accordingly, so that the shaft then floats in the lubricating oil without metallic contact with the bearing parts.In this example, the bearing metal 13 is only shown in the upper left quadrant , which is designed only over the narrower part of the bearing play.



   Fig. 2 now shows a radial bearing with four symmetrically arranged bearing parts 6, 7, 8 and 9, which, however, according to the second manufacturing process described above, were assembled during their pre-machining with spacer strips inserted between their flanges 10 and turned out cylindrically. The cross-section of these bearing parts thus forms the tread is no longer a full quarter circle, but it is shortened by a few degrees of angle after the spacer strips have been omitted, so that the clearance is now narrowest in each quadrant in the middle and widened too wedge-shaped against both flanges; here all four bearing parts are lined with bearing metal 13 on a peripheral section.

   It is readily apparent that this embodiment of radial bearings shown in FIG. 2 can easily be used for both directions of rotation of the shaft A.



   The method according to the invention can of course be used in the same way and with the same effect for those with a different division of the bearing shells, in addition to producing the four-part radial bearings shown for example.



    PATENT CLAIMS:
1. A method for the production of radial bearings with hydrodynamic lubrication - preferably for vertical shafts - which are composed of several bearing parts with circular cylindrical running surfaces each eccentrically to the bearing axis, characterized in that a multi-part - preferably four-part - bearing initially in the assembled state cylindrical on a common The inner diameter of its parts is turned out, which is slightly larger than the largest permissible diameter of the shaft to be used (A), after which the bearing is dismantled again and finally the identical bearing parts are assembled eccentrically with their running surfaces.
