Abstract (en)
[origin: JP2015165135A] PROBLEM TO BE SOLVED: To provide a vacuum pump, particularly a turbo molecular pump, and a method for which a stator disc has feasibly high geometrical flexibility and can be manufactured at a low cost as easily and appropriately as possible.SOLUTION: A stator disc 86 in a vacuum pump, particularly a turbo molecular pump 84, comprises at least two stator disc parts 92, preferably two stator disc half parts including a plurality of thin plate blade parts continuous in a peripheral direction and having a partial ring shape, each of the stator disc parts 92 of the partial ring shape including a plurality of thin plate partial segments 94, the thin plate partial segments 94 of the stator disc parts 92 of the partial ring shape being connected to one another via a common injection molded member 100 in an inner circumference 96 and/or an outer circumference 98.
Abstract (de)
Eine Statorscheibe (86) einer Turbomolekularpumpe (10, 84) umfasst wenigstens zwei teilringförmige Statorscheibenabschnitte (92), vorzugsweise zwei Statorscheibenhälften, mit jeweils mehreren in Umfangsrichtung aufeinanderfolgenden Blechschaufeln. Dabei sind die teilringförmigen Statorscheibenabschnitte (92) jeweils aus mehreren einzelnen Blechteilsegmenten (94) gebildet und die einzelnen Blechteilsegmente (94) eines jeweiligen teilringförmigen Statorscheibenabschnitts (92) im Bereich deren Innen- und/oder Außenumfangs (96 bzw. 98) über ein gemeinsames Spritzgussformteil (100) miteinander verbunden. Es werden auch eine Turbomolekularpumpe (10, 84) mit zumindest einer solchen Statorscheibe (86) sowie ein Verfahren zur Herstellung einer solchen Statorscheibe (86) angegeben.
