"Wabenmuater - fflanschverrippun^" Beschreibung;!"Wabenmuater - fflanschverrippun ^" Description;!

Zum Aufspulen von £upferdrahten für die Slektro-Industrie werden Spulen benötigt,die früher meistens in Holz,heute in Kunststoff ausgeführt werden·Solche Spulen in Kunststoff sind bereits zu Millionen am Markt«Da der Seltendruck auf die Flansche bei diesen Spulen ziemlich groß ist »sind fast alle am Markt befindlichen Kunststoffspulen wie folgt konstruiert! Bin verhältnismäßig dünner Seitenflansch(a)wird an seinem Außenrand durch einen senkrecht auf ihm stehenden Hand(b)verstärkt. Eine weiter· und zwar die wesentliche Verstärkung sollen ebenfalle senkrecht zum Flansch(a) stehende Hippen bringen, die den Eand(b)mit dem Spulenk8rper(o)verbinden· Diese ,im Folgenden lure Flanschrippen genannten Verstärkungen sind bisher so ausgebildet, daß sie radial oder fast radial verlaufen·Wird daher der Flansch beansprucht,so läuft die sogenanate"BruchlinieM(d),nachdem sie den Außenrand gebrochen hat,einfach an einer Flanschrippe entlang bis zum Spul ankern,bricht hier also nur den dünnen Flansch(a) und trifft erst am Spulenkern auf die Hippenverstärkungen* Da an dieser Stelle aber das Biegungsmoment,nach dem Gesetz "Kraft mal Hebelarm11 am größten ist ,brechen hier die Bippen verhältnismäßig leicht.
Die !Teuerung besteht nunmehr darin,daß die Hippen nicht mehrFor winding up wire for the slektro industry, reels are required, which in the past are mostly made of wood, today they are made of plastic. Almost all plastic reels on the market are constructed as follows! A relatively thin side flange (a) is reinforced on its outer edge by a hand (b) standing vertically on it. Another reinforcement, namely the essential reinforcement, should also be provided by ribs that are perpendicular to the flange (a) and that connect the end (b) to the coil body (o) or run almost radially · If the flange is therefore stressed, the so-called "break line M (d), after it has broken the outer edge, simply anchors along a flange rib to the spool, so only breaks the thin flange (a) and here only meets the rib reinforcements at the coil core * Since the bending moment, according to the law "force times lever arm 11, is greatest at this point, the ribs break relatively easily here.
The price increase now consists in the fact that the hip no longer
