Abstract
Herstellverfahren für ein Maschinengehäuse oder dgl., dessen Gehäusewand (1) einen im wesentlichen wendelförmig verlaufenden Kühlmittelkanal (4) enthält, dadurch gekennzeichnet, dass die Gehäusewand (1) durch wendelförmiges Wickeln eines verformbaren Hohlprofiles (6), welches den Kühlmittelkanal (4) bildet und durch nachfolgendes stoffschlüssiges Verbinden der nebeneinander liegenden Hohlprofil-Abschnitte (6a, 6b) gebildet wird, wobei als Hohlprofil (6) ein rechteckiges Strangpressprofil verwendet wird.manufacturing for a machine housing or the like., The housing wall (1) a substantially helical coolant channel (4) contains characterized in that the housing wall (1) by helical winding a deformable hollow profile (6), which the coolant channel (4) forms and by subsequent cohesive bonding of the side by side lying hollow profile sections (6a, 6b) is formed, wherein as a hollow profile (6) is a rectangular Extruded profile is used.
Description
Die Erfindung betrifft ein Herstellverfahren für ein Maschinengehäuse mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1.The The invention relates to a manufacturing method for a machine housing with the features of the preamble of claim 1.
Aus
der
Nachteilig an dem bekannten Maschinengehäuse für eine elektrische Maschine ist insbesondere das hohe Gewicht.adversely on the known machine housing for one Electric machine is especially the heavy weight.
Weiter
ist aus der
Nachteilig bei der beschriebenen Ausführung ist, dass die Profilträger auf einen Grundträger geschweißt werden müssen, wobei die innen liegenden Schweißnähte, zumindest die letzte innen liegende Schweißnaht, nicht mehr zugänglich ist. Hierdurch kann Kühlluft von einem Kühlkanal in den anderen Kanal übertreten. Eine absolute Dichtheit ist mit der Konstruktion nicht möglich. Ferner ist die Fertigung sehr aufwendig und teuer.adversely in the described embodiment is that the profile beam be welded to a base support have to, with the inside welds, at least the last inside lying weld, no longer accessible is. This allows cooling air from a cooling channel into the other channel. An absolute tightness is not possible with the construction. Further the production is very complicated and expensive.
Aufgabe der vorliegenden Erfindung ist es, ein sehr leichtes, vollständig dichtes und kostengünstig zu fertigendes Maschinengehäuse darzustellen.task The present invention is a very light, completely dense one and cost-effective to be manufactured machine housing display.
Diese Aufgabe wird durch die Merkmale im kennzeichnenden Teil des Patentanspruchs 1 dadurch gelöst, dass die Gehäusewand durch wendelförmiges Wickeln eines verformbaren Hohlprofiles, welches den Kühlmittelkanal bildet und durch nachfolgendes stoffschlüssiges Verbinden der nebeneinander liegenden Hohlprofil-Abschnitte gebildet wird, wobei als Hohlprofil ein rechteckiges Strangpressprofil verwendet wird.These The object is achieved by the features in the characterizing part of the claim 1 solved by that the housing wall by helical Winding a deformable hollow profile, which the coolant channel forms and by subsequent material connection of the side by side lying hollow profile sections is formed, wherein as a hollow profile a rectangular extruded profile is used.
Besonders bevorzugt ist der Werkstoff für das Hohlprofil Aluminium.Especially preferred is the material for the Hollow profile aluminum.
Näher erläutert wird die Erfindung anhand eines bevorzugten Ausführungsbeispieles, wobei die beigefügte Figur ein erfindungsgemäß hergestelltes Maschinengehäuse in einem Prinzip-Teilschnitt zeigt.It will be explained in more detail the invention with reference to a preferred embodiment, wherein the accompanying figure an inventively manufactured machine housing in one Principle partial section shows.
