Description
SCHRAUBENKÖRPER VON SCHRAtJBENVERDICHTERNSCREW BODIES OF SCREW COMPRESSORS
.Die Erfindung betrifft ein Verfahren zur Herstellung der Schraubenkörper von Schraubenverdichtern, und die Ausgestaltung von danach hergestellten Schraubenkörpern. The invention relates to a method for producing the Screw bodies of screw compressors, and the design of screw bodies manufactured accordingly.
Es ist bekannt, die längs ihres Durchdrxnigungsbereiches ineinandergreifenden sogenannten männlichen und weiblichen Schraubenkörper eines solchen Verdichters aus einem Zylinder auf einer Formfräsmaschine zu erzeugen, wobei aber ein beträchtlicher Volumenanteil des zylindrischen Rohlings abgetragen werden muß. Wegen des dadurch entstehenden Materialverlustes und der umfangreichen spanabhebenden Bearbeitung ist dieses Herstellungsverfahren sehr aufwendig, besonders wenn hartes Material verarbeitet werden muß.It is known that along its range of penetration interlocking so-called male and female Screw body of such a compressor from a cylinder to produce on a form milling machine, but a considerable amount Volume fraction of the cylindrical blank must be removed. Because of the resulting loss of material and the extensive machining, this manufacturing process is very expensive, especially when hard material has to be processed.

Erfindungsgemäß soll der Herstellungsaufwand vermindert werden. Dies geschieht dadurch, daß zur Herstellung der Schraubenkörper von Schraubenverdichtern mehrere identische Lamellen, entsprechend dem Schraubenprofilmit einer Zentralbohrung, ausgestanzt und dann nacheinander^ in Umfangsrichtung entsprechend der Schraubendrehung versetzt, auf eine die Zentralbohrungen ausfüllende Welle geschoben und sodann zwischen beiderseits auf die Welle geschobenen Büchsen oder Stellringen zusammengepreßt werden, wonach die Schraubenfläche durch Profilschleifen erzeugt wird.According to the invention, the manufacturing cost is to be reduced. This is done by making the screw body several identical lamellas are punched out by screw compressors, corresponding to the screw profile with a central hole and then one after the other ^ offset in the circumferential direction according to the rotation of the screw, onto one of the central bores Filling shaft pushed and then pressed together between sleeves or collars pushed onto the shaft on both sides after which the screw surface by profile grinding is produced.
Dabei kann das Versetzungsmaß der jeweils benachbarten aufgeschobenen Lamellen durch Anlegen einer Lehre vor dem Zusammenpressen eingestellt werden, was den Vorteil hat, daß auch ein längs der Achse veränderliches Steigungsmaß durch eine entsprechend gestaltete Lehre bequem realisiert werden kann.The offset dimension of the respectively adjacent postponed Slats can be adjusted by applying a gauge before pressing together, which has the advantage that a along the axis variable pitch can be easily realized by an appropriately designed gauge.
Vor allem bei über die Länge gleichbleibender Steigung wird die Schraubenkörpermontage dadurch, vereinfacht, daß in die ¥ellenoberfläche vor dem Aufschieben der Lamellen eine spiralige Führungsnut geschnitten wird, und eine entsprechende Führungsnase in der Lamellenbohrung am Stanzen ausgespart wird. Das Anlegen einer Lehre erübrigt sich dadurch.The screw body assembly is simplified by the fact that in the On the surface of the lamella, a spiral guide groove is cut before the slats are slid on, and a corresponding guide nose is cut out in the slat hole on the punch. That There is no need to create a teaching.
Gegenstand der Erfindung ist auch ein so hergestellter Schraubenkörper, gekennzeichnet durch eine Welle, worauf ein Stapel von identischen Lamellen entsprechend dem Schraubenproiil gelagert ist, die gegeneinander in Umfangsrichtung entsprechend der Schraubensteigung versetzt und axial zusammengepreßt sind durch beiderseits auf die Welle geschobene Büchsen oder Klenunringe, wobei wenigstens eine spiralige Führungsnut in die Wel— lenoberfläche geschnitten sein kann, in welche Nut die Lamellen mit je wenigstens einer ihrer Bohrung anwachsenden Führungsnase fassen. The invention also relates to a screw body produced in this way, characterized by a shaft, on which a stack of identical lamellas is mounted corresponding to the screw profile which are offset from one another in the circumferential direction according to the screw pitch and axially compressed through bushings or Klenun rings pushed onto the shaft on both sides, wherein at least one spiral guide groove can be cut into the shaft surface, in which groove the lamellas grasp with at least one of their bore growing guide nose.
Die Erfindung möge anhand der in den Figuren schematisch dargestellten Ausführungsbeispiele weiter erläutert werden.The invention should be explained further with reference to the exemplary embodiments shown schematically in the figures.

Die Schraubenkörper bestehen aus Lamellen 1 bzw. la entsprechend dem männlichen, und Lamellen 2a entsprechend dem weiblichen Schraubenprofil, jeweils gestapelt auf einer Welle 2 bzw. 2a, und gegeneinander in UmfangsrJUchtung versetzt entsprechend dem Steigungsmaß des Schraubenkörpers,der vervollständigt ist durch der Welle beiderseits aufeschobene, aufgeschrumpfte Büchsen 3» (Fig. 5)»Vwelche den Stapel aus Lamellen axial zusammenpressen.The screw body consists of lamellae 1 or la corresponding to the male, and lamellae 2a corresponding to the female Screw profile, each stacked on a shaft 2 or 2a, and offset against each other in the circumferential direction accordingly the pitch of the screw body, which is completed by the shrunk-on bushings 3 (Fig. 5) which are pushed on on both sides of the shaft, which is the stack of lamellas compress axially.

Die Schraubenoberfläche kann in der gewünschten Toleranz durch Profilschleifen mit geringer Materialabtragung erzeugt werden, oder auch durch entsprechend dünne und viele Lamellen im dem Schraubenkörper bildenden Stapel.In the exemplary embodiment according to FIGS. 3 and 4, the offset of adjacent lamellae is fixed by a spiral Guide groove 4 on the shaft 2a, in each of which a guide nose 5 in the bore of each lamella 2a or la summarizes, as from, Fig. 4 can be seen. The screw surface can be machined to the desired tolerance by profile grinding with little material removal are generated, or by correspondingly thin and many lamellae in the stack forming the screw body.
