Abstract
Vakuumpumpe (1) mit einem Montagemittel (6), welches eine der Schwerkraftrichtung entsprechenden Senkrechte (100; 200) festlegt, welche die Flächennormale einer Montageebene bildet, einer Welle (30; 28; 230; 330; 328) mit einer Wellenachse (112; 212), einem Raum (20, 22; 220), welcher zur Aufnahme einer Schmiermittelfüllmenge (72; 74) dient, einer auf der Welle angeordneten Schleuderstruktur (60, 70; 260) zur Verteilung von Schmiermittel im Raum, einem Ölrücklauf (54; 254; 354; 356), welcher den Rücklauf von Schmiermittel in den Raum erlaubt und eine in diesen geöffneten Auslauf (58; 258; 258'; 358) aufweist, wobei eine in Bezug zur Schwerkraftrichtung unterhalb der Welle angeordnete Auslaufebene (108; 208) den Auslauf beinhaltet und parallel zur Montageebene ist, eine Schnittpunktebene (106; 206) den in Bezug zur Schwerkraftrichtung tiefsten im Betrieb der Schleuderstruktur erreichten Punkt (104) beinhaltet und parallel zur Montageebene ist und der Abstand (110; 210) zwischen Auslaufebene und Schnittpunktebene groß ist. A vacuum pump (1) having a mounting means (6) defining a vertical direction of gravity (100; 200) which constitutes the surface normal of a mounting plane, a shaft (30; 28; 230; 330; 328) having a shaft axis (112; 212), a space (20,22; 220) serving to receive a lubricant charge (72; 74), a centrifugal structure (60,70; 260) disposed on the shaft for distributing lubricant in the space, an oil return (54; 254; 354; 356), which permits the return of lubricant into the space and has an outlet (58; 258; 258 '; 358) opened in the space, wherein an outlet plane (108; 208) arranged in relation to the direction of gravity below the shaft. includes the exit and parallel to the mounting plane, an intersection plane (106; 206) includes the lowest point (104) reached in the operation of the spin structure with respect to the direction of gravity and parallel to the mounting plane and the distance (110; 210) between Au slaufebene and intersection level is large.
