Description
Die Erfindung bezieht sich auf ein Verfahren zum Herstellen eines Pumpenläufers, insbesondere für Seitenkanalpumpen. The invention relates to a method for producing a pump rotor, in particular for side channel pumps.
Um den unterschiedlichen Anforderungen bezüglich der Förderleistung und der Förderhöhe bei Seitenkanalpumpen zu entsprechen, ist es erforderlich, eine Vielzahl von Läufern zur Verfugung zu haben, die sich bezüglich ihres Durchmessers und ihrer Wandstärke unterscheiden, so daß es möglich ist, entsprechend verschiedene 'Pumpenmodelle herzustellen. Beim Konstruieren von Pumpen unterschiedlicher Art ist es ferner aus mechanischen Gründen erforderlich, den Läufernaben unterschiedliche Abmessungen zu geben, obwohl die eigentlichen Läuferteile oder Läuferscheiben gleichartige Abmessungen haben. Bei den gegenwärtig gebräuchlichen Verfahren zum Herstellen solcher Pumpenläufer läßt es sich nicht vermeiden, daß Läufer der verschiedensten Größe in großen Stückzahlen maschinell bearbeitet und auf Lager gehalten werden. Der Erfindung liegt die Aufgabe zugrunde, die Notwendigkeit einer solchen umfangreichen Lagerhaltung zu vermeiden. Ihr liegt das Prinzip zugrunde, daß scheibenförmige Läufer von unter-In order to meet the different requirements in terms of delivery rate and delivery head for side channel pumps it is necessary to have a large number of sliders available, which differ in terms of their diameter and their wall thickness, so that it is possible to manufacture different 'pump models. At the Constructing pumps of different types, it is also necessary for mechanical reasons to give the rotor hubs different dimensions, although the actual Rotor parts or rotor disks have similar dimensions. In the methods of manufacture currently in use Such pump rotors can not be avoided that rotors of various sizes in large numbers machined and kept in stock. The invention The underlying task is to avoid the need for such extensive storage. Her lies is based on the principle that disc-shaped rotors are

Gemäß'dem Verfahren nach der: Erf indung wird vor dem Montieren der Läuferscheibe auf der Habe eine geradlinige grobe Riffelung in einen einen kleineren Durchmesser aufweisenden Abschnitt der Habe eingeschnitten, und beide Enden der kreisrunden zentralen Bohrung der Läuferscheibe werden maschinell abgeschrägt. Um die Lauferscheibe auf der Habe zu montieren, . wird der geriffelte Teil des dünneren Abschnitts der Habe in' " die zentrale Bohrung der Läuferscheibe hineingepreßt, und dann wird der' äußere ringförmige Hand des dünneren Habenabschnitts gegen"die benachbarte' Abschrägung der Läuferscheibe umgebördelt:, um die Läuferscheibe in fester Anlage an der Schulter zwischen ..den beiden Abschnitten der Habe zu halten.According to the method according to the invention, a straight, coarse corrugation is cut into a smaller diameter section of the hub before the carrier is mounted on the carrier, and both ends of the circular central bore of the carrier are beveled by machine. To mount the bearing washer on the property,. the corrugated part of the thinner section of the hub is pressed into the central bore of the carrier, and then the outer ring-shaped hand of the thinner section is flanged against the adjacent bevel of the carrier : around the carrier in firm contact with the shoulder to hold between ... the two sections of the property.

In Pig* 1 erkennt man eine lauferscheine 10, die an ihrem Umfang mit mehreren taschenähnlichen Turbinenschaufelh 12 versehen ist, sowie eine Habe 14 mit einem Abschnitt 16 von kleinerem Durchmesser. Die Ücheibe 10 weist eine zentrale Öffnung 18 auf, die auf beiden Seiten der Scheibe an ihren Enden, mit je einer Abschrägung 20 versehen ist.In Pig * 1 one recognizes a running license 10, which its scope with several pocket-like turbine blades 12 is provided, as well as a hat 14 with a portion 16 of smaller diameter. The Ücheibe 10 has a central opening 18, which on both sides of the disk at its ends, is provided with a bevel 20 each.
Die'Nabe 14 wird' als Massenteil auf einem Schraubenauto-'maten hergestellt-· In den dünneren Abschnitt 16 der Nabe werden nahe der Schulter 24 mehrere Längsnuten 22 eingeschnitten, um die Nabe mit einem Abschnitt 26 zu versehen, der eine gerade Eiffeiung von grober Teilung aufweist. Das ringförmige äußere Ende 28 des dünneren Nabenabschnitts 16 wird so bear-" beitet, daß sein Durchmesser der Tiefe der Nuten 22 entsprichtThe 'hub 14 is' as a mass part on a screw car' mat - In the thinner section 16 of the hub near the shoulder 24 several longitudinal grooves 22 are cut, to provide the hub with a portion 26 which has a straight Eiffeiung of coarse pitch. The ring-shaped outer end 28 of the thinner hub portion 16 is machined works so that its diameter corresponds to the depth of the grooves 22
Um die Läuferscheibe 10 auf der Nabe 14 zu montieren, wird der geriffelte Nabenabschnitt 26 in die zentrale Öffnung 18 der Lauferscheibe eingepreßt, so daß in die Wand der Öffnung 18 entsprechende Nuten 30 eingeschnitten werden, wie es in I1Ig. 3 gezeigt ist, bis die innere Seite der Scheibe 10 zur Anlage an der Schulter 24 der Nabe kommt. Dieser Preßvorgang führt zum Entstehen einer guten Antriebsver/bindung zwischen der Läuferscheibe 10 und der Nabe 14, die ebenso wirksam ist wie ein We_llenkeil oder eine Keilverzahnung, ohne daß sich eine zu große Maßübersehneidung ergibt, die zu einem Verziehen der Läuferscheibe führen könnte.In order to mount the carrier disk 10 on the hub 14, the corrugated hub section 26 is pressed into the central opening 18 of the carrier disk, so that corresponding grooves 30 are cut into the wall of the opening 18, as shown in I 1 Ig. 3 until the inner side of the disc 10 abuts the shoulder 24 of the hub. This pressing process leads to the creation of a good drive connection between the carrier disc 10 and the hub 14, which is just as effective as a shaft wedge or a spline, without causing too great a dimensional overlap which could lead to warping of the carrier disc.
Die in Pig., 2 dargestellte ,Baugruppe wird dann in, eine Presse eingelegt, mittels welcher gemäß Fig. 4 der ringförmige äußere Rand 28 des dünneren Nabenabschnitts 16 gegen die benachbarte ■ Abschrägung 20 der Läuferscheibe umgebördelt wird, um die Läuferscheibe in fester Anlage an der Schulter 24 der Nabe 14 zu halten. Bei dem zu diesem Bördelvorgang benutzten Werkzeug handelt es sich um eiäen auf besondere Weise konstruierten konzentrischen Ring,5 "der bewirkt, daß der umgebördelte, Abschnitt 34 eine pit der ,Nabe': 14 konzentrische Porm erhält. Der Innendurchmesser des:ringf8rmigßn¥WerkzeugsThe assembly shown in Pig., 2, is then placed in a press, by means of which, according to FIG the shoulder 24 of the hub 14 to hold. The tool used for this crimping process is a specially constructed concentric ring 5 "which causes the crimped section 34 to have a concentric shape of the" hub "14. The inner diameter of the ring-shaped tool
Matrize ist so gewählt, daß sich, der gesamte verlagerte Werkstoff in Richtung auf die Läuferscheibe 10 und nicht etwa in Richtung auf die Bohrung der Habe bewegt, wie es geschehen · würde, wenn das freie Ende 28 der Nabe 14 über seine ganze Stirnfläche mit Hilfe eines flachen Werkzeugs umgebördelt würde.Die is chosen so that the entire displaced material moved in the direction of the carrier plate 10 and not in the direction of the bore of the property, as happened would if the free end 28 of the hub 14 crimped over its entire end face with the aid of a flat tool would.
Nach dem Umbördeln wird der so hergestellte zusammengesetzte Läufer in der üblichen Weise einer Fertigbearbeitung unterzogen, damit er genau die gewünschten Abmessungen erhält} Fig. 5 zeigt den fertigen zusammengesetzten Läufer, der auf einer Welle 40 angeordnet und mit der Welle durch einen Keil 42 verbunden ist.After the flanging, the composite is produced in this way The rotor is finished in the usual way so that it has exactly the desired dimensions} Fig. 5 shows the finished assembled rotor positioned on a shaft 40 and connected to the shaft by a key 42 is connected.
Aus der vorstehenden Beschreibung ist ersichtlich, daß das Herstellen eines Läufers durch Montieren einer Läuferscheibe auf einer Nabe unter Anwendung des erfindungsgemäßen Verfahrens mehrere Torteile bietet, die darin bestehen, daß sich die Lagerhaltung vereinfacht, daß einfachere maschinelle Arbeitsschritte durchgeführt werden können, und daß die benötigten Bauteile im Wege der Massenfertigung auf Schraubenautomaten hergestellt werden könne, während sie bis jetzt in kleineren Stückzahlen und auf kostspieligere Weise unter Benutzung von Maschinen mit Spannfuttern hergestellt werden.From the above description it can be seen that the manufacture of a rotor by mounting a rotor disc on a hub using the invention Method offers several parts of the gate, which consist in the fact that storage is simplified that simpler machine Work steps can be carried out, and that the required Components can be mass-produced on screw machines, while they have so far been in can be manufactured in smaller numbers and in a more costly manner using machines with chucks.
