Abstract

The shaft (10) has axial ducts in (13,14) and a pipe (2) sitting tightly on it so that it is sealed. The cross-sectional surfaces (23,24) of the ducts (13,14) are hollowed out from the cross-sectional surface (25) of the shaft (1). The ducts (13,14) lead into windows (5-8) in the pipe (2). The windows (5-8) are long in a peripheral direction, and narrow in an axial direction. USE/ADVANTAGE - The shaft withstands high loads and has ducts in which are easily produced.

Description

Die Erfindung betrifft eine Welle mit axialen Kanälen. Eine Welle dieser Art wird verwendet, wenn über die Welle ein Verbraucher oder mehrere Verbraucher mit getrennten Fluidströmen versorgt werden müssen. Die axialen Kanäle sind meist gleichmäßig über den Querschnitt der Welle verteilt. Sie müssen oft durch Tieflochbohren, manchmal sogar von beiden Enden her, gefertigt, an mindestens einem Ende wieder verschlossen und durch Querbohrungen ergänzt werden. Tieflochbohren ist aufwendig, weil mehrere Bohrhübe nötig sind, der Bohrer kann aus der Richtung laufen oder brechen, weil Bohrspäne das Bohrloch verstopfen. Die Querbohrungen mit ihrer Kerbwirkung bedeuten Bruchgefahr für eine hoch beanspruchte Welle.The invention relates to a shaft with axial channels. A wave of this type is used when over the wave one consumer or multiple consumers with separate Fluid flows must be supplied. The axial channels are mostly evenly distributed over the cross-section of the shaft. They often have to go through deep hole drilling, sometimes even from both ends, manufactured, at least one end again closed and supplemented by cross holes. Deep hole drilling is complex because several drilling strokes are necessary the drill can run or break from the direction because drilling chips clog the borehole. The cross holes with their notch effect mean risk of breakage for a high stressed wave.

Bei einer bekannten Welle dieser Art (Bild 12, Seite G70, in Dubbel-Taschenbuch für den Maschinenbau, 16. Auflage, Springer-Verlag Berlin 1987) versorgt ein erster axialer Kanal das Lamellenpaket einer auf der Welle angeordneten Kupplung mit Kühl- und Schmieröl, und ein zweiter axialer Kanal versorgt einen Ringkolben in einem mit der Welle drehenden Ringzylinder mit Drucköl zum Schließen der Kupplung.With a known shaft of this type (Figure 12, page G70, in Dubbel paperback for mechanical engineering, 16. Edition, Springer-Verlag Berlin 1987) supplies a first axial channel the plate pack one on the shaft arranged clutch with cooling and lubricating oil, and a second axial channel supplies an annular piston in one the shaft rotating ring cylinder with pressure oil to close the clutch.

Der Erfindung liegt die Aufgabe zugrunde, eine Welle der eingangs beschriebenen Art zu schaffen, die hohen Belastungen standhält, und bei der die Fertigung der Kanäle wenig Aufwand fordert.The invention has for its object a shaft to create the high described Withstands loads, and in the manufacture of the channels requires little effort.

Diese Aufgabe wird mit den Merkmalen nach Anspruch 1 gelöst, weil die Querschnittflächen der axialen Kanäle außen aus der Querschnittfläche der Welle ausgespart und durch ein auf der Welle angeordnetes Rohr nach außen begrenzt werden. This object is achieved with the features of claim 1 solved because the cross-sectional areas of the axial channels outside recessed from the cross-sectional area of the shaft and by a pipe arranged on the shaft are limited to the outside.  

Fenster in dem Rohr ergänzen die axialen Kanäle derart, daß jeder Verbraucher mit einer Fluidquelle verbunden werden kann.Windows in the tube complement the axial channels in such a way that each consumer can be connected to a fluid source can.

Wenn das Rohr fest und dicht auf der Welle sitzt, bleiben Leckverluste und gegenseitige Störungen besonders gering (Anspruch 2) .If the tube is tight and tight on the shaft, leakage and mutual interference remain special low (claim 2).

Ein Fenster nach Anspruch 3 mit geringer Breite in Achsrichtung und großer Länge in Umfangsrichtung bietet größeren Durchflußquerschnitt als eine einfache Bohrung mit gleichem axialen Platzbedarf.A window according to claim 3 with a small width in Axis direction and great length in the circumferential direction offers larger flow cross section than a simple bore with same axial space requirement.

Fig. 1 to 5: A shaft 1 has two opposite first longitudinal grooves 3 and two mutually opposing second longitudinal grooves. 4 A tube 2 sits tightly and tightly on the shaft 1 and forms two first and second axial channels 13 , 14 together with the longitudinal grooves 3 , 4 . A first consumer (not shown) can be connected to a first fluid source (not shown) via first windows 5 , 6 in the tube 2 and the first axial channels 13 . A second consumer (not shown) can be connected to a second fluid source (not shown) via second windows 7 , 8 in the tube 2 and the second axial channels 14 . Cross-sectional areas 23 , 24 of the channels 13 , 14 are delimited by circular arcs 9 , 10 , 11 , 12 .

Fig. 6 bis 8: die Querschnittflächen 23, 24 der Kanäle 13, 14 werden anders begrenzt: Figures 6 to 8. The cross-sectional surfaces 23, 24 of the channels 13, 14 are otherwise limited:

Fig. 6 die Längsnuten 3, 4 sind Rechtecknuten; Fig. 6, the longitudinal grooves 3 , 4 are rectangular grooves;

Fig. 7 die Welle 1 hat Planflächen 15, 16; Fig. 7 the shaft 1 has flat surfaces 15 , 16 ;

Fig. 8 die Welle 1 hat ein unrundes Gleichdickprofil, ein sogenanntes Polygon-Profil. Fig. 8 the shaft 1 has a non-circular constant thickness profile, a so-called polygon profile.

Die Welle 1 und das Rohr 2 können beispielsweise durch Schrumpfen, Schweißen, Löten oder Kleben fest und dicht miteinander verbunden sein. Die Fenster 5, 6, 7, 8 können rund oder in Umfangsrichtung länglich und beispielsweise durch Bohren, Fräsen, Schleifen oder Stanzen hergestellt sein.The shaft 1 and the tube 2 can, for example, be firmly and tightly connected to one another by shrinking, welding, soldering or gluing. The windows 5 , 6 , 7 , 8 can be round or elongated in the circumferential direction and produced, for example, by drilling, milling, grinding or punching.
