Description

Transportrolle mit außen hartem Mantel Transportrollen unterliegen oft einem starken Verschleiß an der Mantelfläche. So werden z. B. die im Bergbau zum Antrieb von Förderbändern und Schleuderbändern benutzten Rollen oft durch die schmirgelnde Wirkung des Fördergutes stark abgenutzt. Es ist deshalb vorgeschlagen worden, die Rollen aus naturhartem Stähl herzustellen, aber das hat den Nachteil, daß die Bearbeitung der Rollen zu schwierig und zu teuer ist. Oft genügt außerdem die Verschleißfestigkeit dieses Stahls nicht. Das Außenhärten der Rollen durch Einsatzhärtung ergibt keinen den entstehenden Kosten entsprechenden Erfolg.Transport rollers with a hard outer shell are subject to transport rollers often heavy wear on the outer surface. So z. B. those in mining rollers often used to drive conveyor belts and centrifugal belts through the abrasive effect of the conveyed material heavily worn. It is therefore suggested to manufacture the rollers from naturally hard steel, but this has the disadvantage that the processing of the roles is too difficult and too expensive. Often enough, too the wear resistance of this steel is not. External hardening of the rollers through case hardening does not result in a success corresponding to the costs involved.

Erfindungsgemäß wird für den Rollenmantel als Ausgangsmaterial eine Verbundblechplatte benutzt, welche eine die Außenfläche des Mantels bildende härtbare Schicht und eine die Innenfläche desselben bildende nicht härtbare Schicht aufweist, und es wird der Rollenmantel erst nach seiner Herstellung, also insbesondere nach der Herstellung der Bohrungen bzw. i`Tuten für die Befestigungsmittel derart gehärtet, daß eine glasharte Außenschicht entsteht, während die Innenschicht weich und zäh bleibt. Nur eine derart hochgehärtete Laufschicht kann der schmirgelnden Wirkung des Fördergutes widerstehen. Daß eine solche Schicht sehr spröde ist und gegebenenfalls springt, ist bei der Verwendung einer Verbundplatte ohne Bedeutung, da auch nach dem Springen der gehärteten Schicht deren einzelne Teile in ihrer Stellung verharren, weil sie mit der zähen Unterschicht verschweißt sind. Die Herstellung ist einfach und verhältnismäßig billig, da das Verbundblech in bekannter Weise durch Zusammenwalzen verschiedenartiger Bleche erzeugt werden kann und sich aus ihm die Rollenmäntel in der gleichen Weise bilden lassen wie aus anderem Blech.According to the invention for the roll shell as a starting material Composite sheet metal used, which forms the outer surface of the shell curable Layer and a non-hardenable layer forming the inner surface thereof, and it becomes the roll shell only after its manufacture, so in particular after the production of the bores or i`tuts for the fasteners hardened in such a way that a glass-hard outer layer is created, while the inner layer is soft and tough remain. Only such a highly hardened overlay can have the abrasive effect resist the conveyed material. That such a layer is very brittle and possibly jumps is irrelevant when using a composite panel, as after the cracking of the hardened layer, the individual parts of which remain in their position, because they are welded to the tough underlayer. It's easy to manufacture and relatively cheap, since the composite sheet is rolled together in a known manner different types of sheet metal can be produced and from it the roller shells let it form in the same way as from other sheet metal.

PATENTANSPRUCH: Transportrolle mit außen hartem Mantel, dadurch gekennzeichnet, daß der Mantel aus einer Verbundblechplatte mit einer die Außenfläche des Mantels bildenden härtbaren Schicht und einer die Innenfläche des Mantels bildenden nicht härtbaren Schicht als Ausgangsmaterial für die Herstellung besteht und erst nach seiner Herstellung gehärtet ist.PATENT CLAIM: Transport roller with outer hard shell, characterized by that the jacket consists of a composite sheet metal plate with the outer surface of the jacket forming hardenable layer and one not forming the inner surface of the jacket curable layer as the starting material for the production and only after its manufacture is hardened.
