Description
Der Erfindung liegt die Aufgabe zugrunde, eine möglichst preiswerte elektrische geschlossene Maschine mit Rippengehäuse zu schaffen, die für normale Betriebsbedingungen, wie sie beispielsweise im Gewerbe und in der Landwirtschaft gegeben sind, geeignet ist. Sie macht dabei Gebrauch von der bekannten Ausführung mit einem um das Ständerblechpaket herumgespritzen Rippengehäuse aus Leichtmetall. Bei den bisher bekannten derartigen Maschinen ist das Ständergehäuse für Aufstellung auf ein Fundament oder eine Grundplatte mit Füßen versehen.The invention is based on the object of providing as inexpensive as possible electric closed machine with ribbed casing to create that for normal Operating conditions, such as those in trade and agriculture given is suitable. It makes use of the known design with a ribbed housing made of light metal sprayed around the stator core. In the previously known machines of this type, the stator housing is for installation provided with feet on a foundation or a base plate.
Derartige Maschinen in Lagerschildausführung mit um das Ständerblechpaket herumgespritztem Rippengehäuse können erheblich verbilligt werden, wenn erfindungsgemäß die beiden Lagerschilde der Maschine auf einer gemeinsamen Fußplatte aufsitzen, die zur Befestigung des Motors am Fundament oder an der Grundplatte dient. Vorzugsweise ist diese Fußplatte muldenförmig gestaltet und an vier konzentrisch zur Maschinenachse zylinderförmig gedrehten Flächen mit den Lagerschilden verschraubt.Such machines in the end shield design with around the stator core Ribbed casing sprayed around can be considerably cheaper if according to the invention the two end shields of the machine sit on a common base plate, which is used to attach the motor to the foundation or to the base plate. Preferably this base plate is trough-shaped and on four concentric to the machine axis Cylindrical turned surfaces screwed to the end shields.
Die Lagerung der Maschine mittels der Lagerschilde auf einer gemeinsamen Fußplatte hat den Vorteil, daß das Ständergehäuse weitgehend von mechanischen Beanspruchungen entlastet ist, so daß die Wandstärke des Gehäuses sehr dünn gehalten und an Spritzmaterial gespart werden kann. Es sind zwar schon elektrische Maschinen bekannt, bei denen nicht das Ständergehäuse, sondern die beiden Lagerschilde mit Füßen versehen sind. Bei diesen bestehen jedoch die Lagerschilde und die Füße aus je einem Stück. Es ist also keine zusammenhängende Fußplatte vorhanden. Bei diesen Maschinen macht die genaue Ausrichtung erhebliche Schwierigkeiten. Meist handelt es sich hierbei nur um Klein- bzw. Kleinstmäschinen, bei denen es auf eine genaue Ausrichtung nicht sehr ankommt.The storage of the machine by means of the end shields on a common The base plate has the advantage that the stator housing is largely protected from mechanical stress is relieved, so that the wall thickness of the housing is kept very thin and of spray material can be saved. It is true that electrical machines are already known in which not the stator housing, but the two end shields are provided with feet. In these, however, the end shields and the feet each consist of one piece. It there is no coherent base plate. With these machines the exact alignment considerable difficulties. Usually this is the case only about small or very small machines, which do not require precise alignment is very well received.
Die Erfindung soll an Hand des in den Fig. i und 2 dargestellten Ausführungsbeispiels näher erläutert werden.The invention is based on the embodiment shown in FIGS are explained in more detail.
Das Gehäuse der dargestellten elektrischen Maschine besteht aus dem fußlosen, mit Kühlrippen versehenen Ständergehäuse i und den beiden Lagerschilden 2 und 3. Das aus Leichtmetall bestehende Ständergehäuse ist um das Ständerblechpaket 4 mit sehr dünner Wandstärke herumgespritzt und zwischen den beiden Lagerschilden 2 und 3 aus Gußeisen mittels Zugbolzen 5 eingespannt. Die Lagerschilde haben auf der Flanschseite Außenringe 6 und 7, die mittels Stegen 8 und 9 mit den flanschseitigen Lagerschildwänden verbunden und auf den Außenflächen bearbeitet sind. Mit diesen bearbeiteten Außenflächen sitzen die Lagerschildringe und damit die Lagerschilde auf vier entsprechend geformten Flächen Io einer für die beiden Lagerschilde gemeinsamen muldenförmigen Fußplatte II auf. Die Auflage der Maschine ist dadurch statisch eindeutig bestimmt. Die Kühlrippen 12 des Ständergehäuses, die über den ganzen Umfang des Ständergehäuses gleichmäßig verteilt werden können, da das Gehäuse keine Füße hat, sind in vier Gruppen aufgeteilt. Die Rippen jeder Gruppe sind parallel gerichtet. Sie sind wie die Wandstärke des Rippengehäuses ebenfalls sehr dünn gehalten. Ein runder Ansatz 13 für die Durchführung der Ständerleitungen ist mit angespritzt. Das Rippengehäuse ist durch einen Blechmantel 14 und der Außenlüfter 15 durch eine Blechhaube 16 abgedeckt. Der Blechmantel 14 ist an den beiden Lagerschildringen 6 und 7 und die Blechhaube 16 an dem einen Lagerschildring 7 befestigt.The housing of the electrical machine shown consists of the footless stator housing i provided with cooling fins and the two end shields 2 and 3. The stator housing made of light metal is around the stator core 4 sprayed around with a very thin wall thickness and between the two end shields 2 and 3 made of cast iron clamped by means of tension bolts 5. The end shields have on the flange side outer rings 6 and 7, which by means of webs 8 and 9 with the flange side End shield walls are connected and machined on the outer surfaces. With these machined outer surfaces sit the end shield rings and thus the end shields on four correspondingly shaped surfaces Io one common to the two end shields trough-shaped footplate II. The support of the machine is statically unambiguous certainly. The cooling fins 12 of the stator housing, which extend over the entire circumference of the Stand housing can be evenly distributed, since the housing has no feet, are divided into four groups. The ribs of each group are directed parallel. Like the wall thickness of the rib housing, they are also kept very thin. A round approach 13 for the implementation of the stator cables is molded on. The rib housing is through a sheet metal jacket 14 and the external fan 15 by a Sheet metal hood 16 covered. The sheet metal jacket 14 is on the two end shield rings 6 and 7 and the sheet metal hood 16 attached to one end shield ring 7.
