Description

Bandage aus schrumpffähigem Material für Anker elektrischer Maschinen und Geräte Es ist üblich, bei elektrischen Maschinen die Wicklung auf dem Anker festzuhalten und gegen Fliehkräfte zu schützen, indem man halboffene Nuten mit Keilen aus, Isoliermaterial verschließt. Es werden auch Kappen aus festen Stoffen, z. B. Metall, übergestülpt, wobei auch vorgeschlagen worden ist, solche Bandagen warm aufzuziehen. Bei Wicklungen, die auf dem Anker aufgelegt wurden, war es auch üblich, eine Bandage aus Schnur- oder Bandmaterial anzubringen und eventuell mit Klebematerial eine weitere Befestigung herbeizuführen. Derartige Bandagen wurden speziell für Wickelköpfe von- Maschinen vorgesehen. Diese Wickelköpfe wurden zudem noch durch. metallische ringförmige Körper oder Drahtwicklungen gegen Zentrifugalkräfte gesichert. Es ist auch bekannt, die Wicklungen elektrischer Maschinen dadurch zu haltern, daß man Bandagen aus thermoplastischem Kunststoff, z. B. auf Polyvinylchloridbasis, verwendet. Derartige Bandagen werden warm aufgezogen und schrumpfen bei Abkühlung, so daß fester Sitz eintritt. Bandagen aus solchem Material haben den Nachteil, daß bei Erwärmung der Maschine auch die Bandage warm wird, wodurch infolge Chlorabspaltung und Wanderung des Weichmachers eine Schädigung der Isolationsmaterialien eintritt.Bandage made of shrinkable material for armature of electrical machines and devices It is common in electrical machines to have the winding on the armature to hold and protect against centrifugal forces by making half-open grooves with wedges off, insulation material closes. There are also caps made of solid materials, such. B. Metal, slipped over, it has also been suggested to keep such bandages warm wind up. In the case of windings that were placed on the armature, it was also common to to attach a bandage made of string or tape material and possibly with adhesive material to bring about a further fastening. Such bandages were specially designed for Winding heads provided by machines. These winding heads were also still through. metallic ring-shaped bodies or wire windings secured against centrifugal forces. It is also known to support the windings of electrical machines in that one bandages made of thermoplastic material, z. B. based on polyvinyl chloride, used. Such bandages are put on warm and shrink when they cool down, so that a firm fit occurs. Bandages made of such a material have the disadvantage that When the machine heats up, the bandage also becomes warm, causing chlorine to be split off and migration of the plasticizer, damage to the insulation materials occurs.

Demgegenüber wird vorgeschlagen, für Bandagen bei elektrischen Maschinen und Geräten Viskose oder Acetylcellulose zu verwenden, welche schrumpft, wenn sie nach erstmaliger Anfeuchtung trocknet. Schrumpfkörper aus derartigem Material sind an sich für Flaschenkapseln bekannt. Ferner ist es bereits bekannt, bei Ständerwicklungen von Unterwassermotoren die Wickelköpfe umhüllenden Kappen aus Acetatfolie zu verwenden, um den Wicklungsraum von Pumpen gegen Eindringen des Wassers zu schützen, wobei diese Kappen jedoch nicht zur Befestigung der Wicklung dienen.In contrast, it is proposed for bandages in electrical machines and devices to use viscose or acetyl cellulose, which shrinks when they are dries after being moistened for the first time. Shrink bodies made of such a material are known per se for bottle caps. Furthermore, it is already known in the case of stator windings to use acetate foil caps enveloping the winding heads of underwater motors, to protect the winding space of pumps against ingress of water, whereby however, these caps are not used to secure the winding.

Erfindungsgemäß wird also die Bandage, die röhrenförmige, ringförmige oder kapselförmige Gestalt hat, eingeweicht und in feuchtem Zustand aufgeschoben. Sie schrumpft dann beim Trocknen, legt sich fest und fixiert. Die erfindungsgemäßen Bandagen können ein- oder mehrstöckig sein. Sie können sowohl über die Gesamtwicklung wie über Teile der Wicklung oder nur über die Wickelköpfe gezogen werden.According to the invention, the bandage, the tubular, ring-shaped or capsule-shaped, soaked and pushed on when moist. It then shrinks as it dries, sets and fixes. The invention Bandages can be single-tier or multi-tier. You can do both about the overall development how to pull over parts of the winding or only over the winding heads.

Bandagen gemäß der Erfindung haben gegenüber den bekannten Bandagen beachtliche Vorteile. Beim Aufbringen solcher Bandagen werden Verletzungen der Wicklung vermieden. Durch den anschließenden langsamen Schrumpfvorgang wird die Wicklung schonend nachgeformt. Diese Formung geschieht auf dem Gesamtumfang gleichmäßig. Ein wesentlicher Vorteil besteht darin, daß solche Bandagen im Gegensatz zu Materialien, die auf Wärme reagieren, beim Betrieb des Motors nicht infolge der dabei auftretenden Erwärmung locker werden.Bandages according to the invention have compared to the known bandages considerable advantages. When applying such bandages, the winding will be injured avoided. The subsequent slow shrinking process results in the winding gently reshaped. This shaping takes place evenly over the entire circumference. A major advantage is that such bandages, in contrast to materials which react to heat, when the engine is running, not as a result of the occurring Warming become loose.
