Description

Man hat bei Elektromotoren für Sprechmaschinen, welche mit sehr engem Lagerspiel laufen müssen, große Schwierigkeiten, mit einem aus Blech bestehenden Gehäuse: einen sicheren, ruhigen und klernrnungsfreien Lauf der. Welle zu erhalten. Erfahrungsgemäß ist der völlig unveränderliche Sitz der Wellenlager für den geräuschlosen Lauf von Sprechmaschinenmoto>ren die wichtigste Bedingung. One has great difficulties with electric motors for speaking machines, which have to run with very tight bearing clearance, with a housing made of sheet metal: a safe, quiet and clear-cut run of the. Wave to get. Experience has shown that the completely unchangeable seat is the Shaft bearings are the most important condition for the silent running of speaking machine motors.

Verwendet man ein bekanntes, aus zwei Schalen bestehendes, in der Horizontalebene geteiltes Blechgehäuse, so ist eine leichte Montage des Motorblechpaketes gewähr leistet, und der feststehende Teil des Motors besitzt eine gute Steifigkeit. Jedoch macht die gute Befestigung sowie das genaue und leichte "Anbringen der Lager und gegebenenfalls auch der Bürstenhalter bei diesen Mo- If you use a well-known, consisting of two shells, in the horizontal plane Split sheet metal housing, so easy assembly of the motor laminated core is guaranteed, and the fixed part of the motor has good rigidity. However does the good fastening as well as the precise and easy "attachment of the bearings and possibly also the brush holder with these mo-

ao toren noch erhebliche Schwierigkeiten.there are still considerable difficulties.

Bei dem Gehäuseaufbau für Sprechmaschinenmotoren nach der Erfindung ergibt sich die Vermeidung dieser Nachteile durch eine Ausbildung der beiden Schalen in der Weise, daß diese breite Flansche aufweisen, welche Aushöhlungen oder Ausprägungen -zwecks Einspannung der Motorlager und gegebenenfalls der Bürstenbrücke besitzen. Durch Jdas klemmende Einspannen dieser Teile mit Hilfe der breiten Flansche ist deren Sitz in völlig einwandfreier Weise gewährleistet, wobei die Genauigkeitsanforderungen ohne weiteren Arbeitsaufwand erfüllt werden. Das Gehäuse erhält überdies dank der breiten Flansche eine hohe Steifigkeit und Verdrehuingsfestigkeit. In the case of the housing structure for speech machine motors according to the invention, these disadvantages are avoided by designing the two shells in such a way that they have wide flanges which have cavities or formations for the purpose of clamping the motor bearings and possibly the brush bridge. J the clamping of these parts with the help of the wide flanges ensures that they are seated in a completely flawless manner, with the accuracy requirements being met without any additional work. In addition, thanks to the wide flanges, the housing has a high degree of rigidity and torsional strength.

In der Zeichnung ist der Aufbau eines Sprechmaschinenmotors mit der Gehäuseausbildung, gemäß der Erfindung perspektivisch dargestellt. Alle Aushöhlungen und Ausprägungen des Flansches F der beiden Schalen S1 und S2 sind ersichtlich; sie spannen beim Zusammenschrauben die Lager L und die Bürstenbrücke '>B ein und sichern deren gewünschte Lage. Die beiden Schalen halten auch das Ständerblechpaket M fest; dies ist jedoch bei der bekannten Bauart (siehe oben) auch bereits der Fall. Der Zusammenbau erfolgt rasch und sicher mit geringen Kosten des gesamten Aufbaues.In the drawing, the structure of a speaking machine motor with the housing design according to the invention is shown in perspective. All cavities and features of the flange F of the two shells S 1 and S 2 can be seen; they clamp the bearings L and the brush bridge '> B when screwing together and secure their desired position. The two shells also hold the stator core M firmly; however, this is already the case with the known design (see above). The assembly takes place quickly and safely with low costs for the entire structure.
