Abstract
Description
Die Erfindung betrifft eine Fliehkraftkupplung entsprechend dem Oberbegriff des Anspruchs 1.The The invention relates to a centrifugal clutch according to the preamble of claim 1.
Fliehkraftkupplungen dieser Art sind bekannt, sie werden vorzugsweise dort eingesetzt, wo Antriebsaggregate zur Entwicklung von mitnahmefähigen Drehmomenten Drehzahlen erreichen müssen, mit welchen die Massenwiderstände der anzutreibenden Maschinen, bzw. Geräte, überwunden werden können.centrifugal clutches of this type are known, they are preferably used there, where drive units for the development of takeaway torques To reach speeds, with which the mass resistances the driven machines, or devices can be overcome.
Darüber hinaus sind die Fliehkraftkupplungen, durch Reibschluss, als Überlastsicherung und zur Abfederung von Überlaststößen geeignet. Sie sind ebenfalls als Fliehkraftbremsen einsetzbar.Furthermore are the centrifugal clutches, by friction, as overload protection and suitable for absorbing overload shocks. They can also be used as centrifugal brakes.
Die Produktion der genannten Fliehkraftkupplungen, insbesondere der Naben, ist sehr arbeitsintensiv und erfordert für die mechanische Bearbeitung hohen Zeitaufwand und teure Spezialwerkzeuge, insbesondere Formfräser. Die mit Reibbelägen versehenen Belagträger sind im allgemeinen an ihren Enden untereinander durch Zugfedern, die zur Bestimmung der Einschaltdrehzahl dienen, verbunden. Der von den Zugfedern beanspruchte Raum verringert die Länge der Fliehgewichte und damit ihr Gewicht, was die Leistungsübertragung der Fliehkraftkupplungen mindert. Ein Wegfall der Belagträger, durch Aufbringen der Reibbeläge auf die Fliehgewichte, bringt eine weitere Einsparmöglichkeit.The Production of said centrifugal clutches, in particular the Hubs, is very labor intensive and requires for mechanical processing high expenditure of time and expensive special tools, in particular form cutters. The with friction linings provided lining carrier are generally at their ends with each other by tension springs, which are used to determine the turn-on, connected. Of the Space occupied by the springs reduces the length of the Flyweights and therefore their weight, giving the power transmission reduces the centrifugal force clutches. An omission of the brake pads, through Applying the friction linings on the flyweights, brings another savings.
Die bisherigen Fliehgewichte und Naben sind vorzugsweise aus Metall, überwiegend aus Stahl gefertigt, an den Mitnahmeflächen führen Erschütterungen beim Einsatz, insbesondere an Rüttelmaschinen und ähnlichen Geräten, zu Verschleißerscheinungen und zu Geräuschen.The Previous centrifugal weights and hubs are preferably made of metal, predominantly made of steel, at the driving surfaces cause vibrations during use, in particular on vibrating machines and similar Devices, to signs of wear and to sounds.
Zur möglichst weitgehenden Lösung der vorstehend genannten problematischen Merkmale sieht die Erfindung vor, die mit hohem Aufwand gefertigten Naben durch solche zu ersetzen, die vorzugsweise aus einem einfach herzustellenden Mittelteil aus Stabstahl und einem aus einem in Spritz- oder Druckgusstechnik hergestellten Mitnahmestern, aus Kunststoff oder speziellem Metall, bestehen.to preferably far-reaching solution the problematic features mentioned above, the invention provides to replace the hubs made with high expenditure by such, preferably from a simple to produce middle part of steel bars and one of a manufactured in injection or diecasting Driving star, made of plastic or special metal exist.
Die bekannten Zugfedern werden durch Flachformfedern ersetzt, damit können die Belagträger entfallen. Durch eine aus Verbundmaterial bestehende neue Nabe werden Stöße und Geräusche verringert.The known tension springs are replaced by flat form springs, so can the brake pads omitted. Become by a composite hub existing new hub Reduced shocks and noise.
Die Erfindung wird nachstehend an einem Beispiel beschrieben und in den Zeichnungen dargestellt.The Invention will be described below by way of example and in illustrated the drawings.
