Description

Auf Zug beanspruchte Isolatoren hat man bereits stabförmig ausgebildet und aus einem Stoff hergestellt, der einem Brennprozeß unterworfen war. Derartige Isolatoren haben den Vorteil, daß sie wetterbeständig sind. Es kommt jedoch häufig vor, daß sie sich beim Brennen an den Enden oder auf die ganze Länge verziehen. Auch kann infolge der Formänderung eines Endes die FassungInsulators subject to tensile stress have already been made rod-shaped and made from one Manufactured fabric that was subjected to a burning process. Have such isolators the advantage that they are weatherproof. However, it often happens that they are warped at the ends or along the entire length when burning. Also as a result the change in shape of one end

Infolgedessen werden bei der Zugbeanspruchung in den Isolatoren Biegungsspannungen auftreten, die zu Bruchbeschädigungen führen können.to get an inclined position to the axis. As a result, the tensile stress Bending stresses occur in the insulators, which can lead to breakage damage.

Derartige ungünstige Beanspruchungen werden erfindungsgemäß dadurch vermieden, daß die Oberfläche der Isolatoren zum mindesten an den Befestigungsstellen geschliffen wird. Es verteilt sich dann der zu übertra-Such unfavorable stresses are avoided according to the invention by that the surface of the insulators is ground at least at the fastening points will. It is then distributed among the

In der Zeichnung ist ein derartiger Isolator beispielsweise dargestellt.Such an isolator is shown, for example, in the drawing.

α ist cfer Isolierkörper, auf dessen keilförmigen Enden die Fassungen & aufgesetzt sind. Sie umgeben die keilförmigen Enden je mit einem keilförmigen Mantel. Daransitzende gegenüberliegende Lappen c mit BoI-zenlöchern d dienen zum Anschluß an die den Zug übertragenden Teile. α is a cfer insulating body, on whose wedge-shaped ends the sockets & are placed. They each surround the wedge-shaped ends with a wedge-shaped jacket. Opposite tabs c with pin holes d are used to connect to the parts transmitting the train.

LTm sicher zu gehen, daß in dem Isolierkörper α keine Biegungsbeanspruchungen, gegen die keramische Stoffe besonders empfindlich sind, auftreten, empfiehlt es sich, die Oberfläche abzuchleifen. Etwaige beim Brennprozeß aufgetretene Formänderungen werden auf diese Weise beseitigt, und jeder Isolator ist unbedingt in der Lage, den durch Rechnung ermittelten Zug mit Sicherheit zu übertragen, da Beanspruchungen auf Biegung ausgeschlossen sind.L T m to ensure that no bending stresses, to which ceramic materials are particularly sensitive, occur in the insulating body α, it is advisable to grind the surface. Any changes in shape that may have occurred during the firing process are eliminated in this way, and every insulator is absolutely capable of reliably transferring the tension determined by calculation, since bending stresses are excluded.
