Abstract

The fan blades (7) are attached by the bolts (6) to the links of the chain (1). The chain (1) is then fitted around the shaft (2) and the end links (3) and (4) are bolted together with the bolt (5). The bolt (5) passes through the space between the rollers with the axis of the bolt perpendicular to the axis of the rollers so that when the bolt is tightened the chain (1) is under tension and exerts a firm grip on the shaft (2). The idea can be used to assemble any form of attachments to a shaft and by choosing a suitable number of links can be adapted to any size of shaft.

Description

Sie kann wahlweise an Stelle von Flügeln Mitnehmer, Schaufeln od. dgl. erhalten. Sie kann auch an anderen Wellendurchmessern durch Verlängern oder Verkürzen zur Anwendung gelangen.You can alternatively instead of wings drivers, shovels or. like received. It can also be used on other shaft diameters by lengthening or Shorten to apply.

Patentanspruch: An Wellen anbringbare nabenartige Haltevorrichtung, die zum Befestigen von Flügeln, Schaufeln, Armen, Mitnehmern u. dgl. dient und aus einer Rollenkettegebildetist, dadurch gekennzeichn e t, daß die als Meterware zur Verfügung stehende Rollenkette (1) endlich ist und ihre Endglieder (3 und 4) durch ein Spannmittel (5) am Wellenumfang fest miteinander verbunden sind, an deren Gelenkzapfen (6) die Flügel (7) usw. befestigt sind. Claim: Hub-like holding device that can be attached to shafts, which is used to attach wings, shovels, arms, drivers and the like a roller chain, characterized in that it is sold by the meter for Available roller chain (1) is finite and its end links (3 and 4) through a clamping device (5) are firmly connected to one another on the circumference of the shaft, on their pivot pins (6) the wings (7) etc. are attached. Die Erfindung bezieht sich auf eine an Wellen anbringbare nabenartige Haltevorrichtung, die zum Befestigen von Flügeln, Schaufeln, Armen, Mitnehmern u. dgl. dient und aus einer Rollenkette gebildet ist. The invention relates to a shaft mountable hub type Holding device that is used to attach wings, blades, arms, drivers and. Like. Serves and is formed from a roller chain. Naben für Wellen sind in vielen Ausführungsformen bekannt. Sie dienen als Grundkörper zur Befestigung oder Anbringung von Elementen aller Art, die dann mit einer Welle oder um eine Welle rotieren können. Solche Naben ein- und mehrteiliger Art müssen im Durchmesser der Welle angepaßt werden und Befestigungsmöglichkeiten erhalten, die aus Löchern, Gewinden und Schweißstellen bestehen können. Es entstehen dadurch Bearbeitungskosten, und die Nabe kann meistens nicht wieder für andere Wellengrößen verwendet werden. Hubs for shafts are known in many embodiments. You serve as a base body for attaching or attaching elements of all kinds, which then can rotate with or around a shaft. Such hubs are one-piece and multi-piece Kind must be adapted in diameter of the shaft and mounting options obtained, which can consist of holes, threads and welds. It arise This means processing costs, and the hub can usually not be used for other shaft sizes be used. Solche Naben können aus einer zylindrischen geschlitzten und radial gespannten Büchse bestehen (DT-OS 1450 122). Such hubs can be slotted cylindrical and radial cocked rifle (DT-OS 1450 122). Die DT-OS 1625502 beschreibt eine Antriebseinrichtung für einen drehbaren zylindrischen Behälter, bei dem eine endlose Kette verwendet werden muß, weil in die Kettenglieder ein Ritzel zwecks Antriebs eingreifen soll. Die Teilung der Kette muß hierbei genau dem Wellen- bzw. Flanschdurchmesser des Zylinders, an dem sie angebracht werden soll, angepaßt sein. Da eine Spannvorrichtung für die offenbarte Kette des drehbaren zylindrischen Behälters in der bekannten Ausführung nicht behandelt worden ist, müssen die Kettenglieder somit ein solches Maß erhalten, daß alle insgesamt dem Durchmesser des Zylinders entsprechen, da sonst eine Mitnahme des Zylinders über die Kette nicht erfolgt. Eine solche Anpassung dürfte sehr schwierig sein. Aus diesem Grund ist auch vorgesehen, daß die endlose Kette mit ihren Gliedern an der Umfangsfläche des Zylinders befestigt ist. Dieser Hinweis dürfte erst die Lösung der bei diesem Stand der Technik gestellten Aufgabe darstellen. The DT-OS 1625502 describes a drive device for a rotatable cylindrical container in which an endless chain must be used because in the chain links engage a pinion for the purpose of drive target. The division of the chain must match exactly the shaft or flange diameter of the cylinder on which it should be attached, adapted. As a jig for the disclosed Chain of the rotatable cylindrical container in the known embodiment not dealt with has been, the chain links must be given such a measure that all together correspond to the diameter of the cylinder, otherwise the cylinder will be entrained not done via the chain. Such an adjustment is likely to be very difficult. For this reason it is also provided that the endless chain with its links is attached to the peripheral surface of the cylinder. This hint should only be the solution represent the task set in this prior art. Aufgabe der Erfindung ist es, die Rollenkette unabhängig vom Wellendurchmesser und ohne mechanische Bearbeitung zu verwenden, schnell zu montieren und zu demontieren. The object of the invention is to make the roller chain independent of the shaft diameter and to use without mechanical processing, to be assembled and disassembled quickly. Die Lösung dieser Aufgabe liegt darin, daß die als Meterware zur Verfügung stehende Rollenkette endlich ist und ihre Endglieder durch ein Spannmittel am Wellenumfang fest miteinander verbunden sind, an deren Gelenkzapfen die Flügel usw. befestigt sind. The solution to this problem is that the yard goods for Available roller chain is finite and its end links through a tensioning device are firmly connected to each other on the circumference of the shaft, on the pivot pin of which the wings etc. are attached. In der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel in der Anbringung an einer Welle dargestellt. In the drawing, the subject matter of the invention is in one embodiment shown attached to a shaft. Die Rollenkette 1 wird um eine Welle 2 gelegt, und die Endglieder 3 und 4 werden miteinander durch Haltemittel 5 verbunden. An den Gelenkzapfen 6 bzw. The roller chain 1 is put around a shaft 2, and the end links 3 and 4 are connected to one another by holding means 5. On the pivot pin 6 respectively. Hohlzapfen werden Flügel 7 od. dgl. angesetzt, so daß z. B. ein Lüfterrad geschaffen werden kann. Die Rollenkette 1 kann leicht montiert und demontiert werden.Hollow pins are wings 7 or the like. Attached, so that, for. B. a fan wheel can be created. The roller chain 1 can be easily assembled and disassembled.
