164 Friction bonding structure and pump device EP12182780.2 2012-09-03 EP2567772A2 2013-03-13 Toyama, Yuichi

An annular groove (21) is formed at an open end of a motor case (5), and a sliding contact projection (22), which is in an annular plate-shape and corresponding to the annular groove (21), is formed on a cover (8). A bottom of the annular groove (21) and the sliding contact projection (22) rotate relative to each other while being in sliding contact with each other to form an annular friction bonded portion (25) therebetween. Wall portions (26, 27) of the annular groove (21) are arranged at such positions as to be concentric with the friction bonded portion (25). Thus, a storage portion (28) that stores burrs (30) produced at the friction bonded portion (25) is formed. A plurality of protrusions (29) that protrude radially outward is formed on the sliding contact projection (22) over all around. The storage portion (28, 28a) is partitioned in the circumferential direction by using the protrusions (29) as partitioning elements.

Offenbart wird eine Vakuumpumpe vorzugsweise mit einem Saugvermögen unter 50 m3/h, mit einem Schraubenpumpenaggregat mit zwei schraubenförmigen, in gegenseitigem Eingriff stehenden Rotoren in einem geeignet geformten Schöpfraum eines Schraubenpumpenstators, der eine Saugseite mit einem Einlass und eine Druckseite mit einem Auslass aufweist, und mit einem Zwei-Wellen-Synchronantrieb mit zwei magnetisierten, sich nicht berührenden Zylindern, die auf die Rotoren tragenden Rotorwellen befestigt sind und diese infolge ihrer gegenseitigen magnetischen Wechselwirkung gegenläufig synchronisieren, und einer oder mehreren, die beiden magnetisierten Zylinder umgebenden Wicklungen eines Motorstators, die durch geeignete Bestromung wandernde Magnetfelder erzeugen dergestalt, dass sich die beiden magnetisierten Zylinder und damit die Rotorwellen gegenläufig synchron drehen, wobei die Lagerung der beiden Rotorwellen nur am Antrieb vorgesehen ist, insbesondere also keine Lagerung auf der vom Antrieb fernen Seite des Schöpfraum vorhanden ist. Diese kann besonders kompakt und präzise gebaut werden, da die Druckseite des Schraubenpumpenaggregates auf der dem Antrieb zugewandten Seite des Schöpfraums liegt und die Lagerung der Rotorwellen und der Antrieb unter Atmosphärendruck stehen.
