Description

In Flüssigkeitsrührwerken, bei denen der Antrieb mittels Kurbelwelle erfolgt, treten infolge der plötzlichen Umkehr der Kurbel Stöße auf, da die beschleunigten Flüssigkeitsmassen der schnellen Umkehr der Rühreinrichtung erhöhten Widerstand entgegensetzen. Diese Stöße haben starke Erschütterungen und 'einen schnellen, einseitigen Verschleiß des k Getriebes zur Folge.In liquid agitators, which are driven by a crankshaft, shocks occur as a result of the sudden reversal of the crank, since the accelerated liquid masses oppose increased resistance to the rapid reversal of the agitator. These shocks have severe vibrations or 'a quick, one-sided wear of the k transmission result.

Um diesen Übelstand zu beseitigen, sieht die vorliegende Erfindung die Verwendung von elliptischen Zahnrädern vor, welche mit ihren periodisch wechselnden Winkelgeschwindigkeiten zur Verlangsamung der Geschwüidigkeit der Kurbelwellendrehung bei der Umkehr der Kurbel dienen sollen. Da aber bei einer Umdrehung der Kurbelwelle zweimal eine Umkehr der Kurbel bzw. der Rühreinrichtung· stattfindet' so muß auch zweimal eine Verlangsamung der Geschwindigkeit erfolgen·.To overcome this drawback, the present invention contemplates use of elliptical gears, which with their periodically changing angular speeds to slow down the speed of the crankshaft rotation when reversing the crank should serve. But since with one revolution of the crankshaft twice one If the crank or the stirring device is reversed, then there must also be two slowdowns the speed.

Dieses bedingt eine zweimalige Umdrehung des elliptischen Zahnräderpaares, da bei einer Umdrehung die Geschwindigkeit der angetriebenen Welle nur einmal von schnell auf langsam wechselt. Durch ein Zahn- oder Kettenräderpaar im Verhältnis 2:1 zwischen angetriebener Welle des elliptischen Zahnrades und der Kurbelwelle werden dann die beiden langsamen Bewegungen auf die Kurbelwelle übertragen, und zwar auf die Kurbelumkehrstellen. This requires a double rotation of the elliptical pair of gears, since one Rotation increases the speed of the driven shaft only once from fast slowly changes. With a pair of gears or sprockets in a ratio of 2: 1 between The driven shaft of the elliptical gear and the crankshaft then become the Transferred both slow movements to the crankshaft, namely to the crank reversing points.

In der beiliegenden Zeichnung ist in Fig. 1 eine Draufsicht, in Fig. 2 und 3 eine Seitenansicht des Rührwerksantriebes mit dem im Rührbehälter 1 hin und her gehenden Rührer dargestellt. 7 ist die antreibende Welle, 2 die getriebene Kurbelwelle mit wechselnden Geschwindigkeiten, 5 und 6 sind die -elliptischen Zahnräder. 4 und 3 sind zwei Kettenräder mit einer Untersetzung von 2:1, welche die zweimalige Umdrehung der Welle 8 auf eine einmalige der Kurbelwelle verringern.In the accompanying drawing, FIG. 1 shows a plan view, FIGS. 2 and 3 show a side view of the agitator drive with the agitator moving back and forth in the agitator tank 1 shown. 7 is the driving shaft, 2 the driven crankshaft with changing speeds, 5 and 6 are the elliptical gears. 4 and 3 are two sprockets with a reduction of 2: 1, which means that the shaft 8 rotates twice to one one-time decrease of the crankshaft.
