Description

Es ist bereits bekannt, die Federungsorgane der F ras werkzeuge alsDrehungsfedeni auszubilden und hierzu zwei oder mehrere solcher zu verbinden, indem die Drehung einer Feder auf die andere mittels Ritzel, Lager usw. übertragen wird. Statt dieser -Hintereinanderschaltung der neb'eneinanderliegenden Stabfedern werden letztere errmdungsgemiü.i (.!nie Zwisehenfügung von Übertragungsorganeu in unmittelbarer Parallelschaltung zueinander angeordnet und an den Enden fest miteinander verbunden. Die so zu einem geschlossenen Paket zueinander gefügten und an den Enden miteinander befestigten Federn bilden so, auf Verdrehung beansprucht, eine Federeinheit, die die Charakteristiken eines Verdrehungsstabes aufweist, jedoch mit dem i/nterschiede. dal! diese in einfacher Weise ' nebeneinander angeordneten Federstäbe ähnliche Eigenschaften aufweisen wie mehrere übereinander oder nebeneinander angeordnete Stabfedern runden, vier- oder mehrkantigen oder röhrenförmigen Querschnitts, zu deren gemeinsamem Wirksammachen die hier vermiedenen C'bertragungsorgane, wie Ritzel, Lager usw., erforderlich sind.It is already known the suspension organs the F ras tools as turning springs to form and this two or more such to connect by the rotation of a Spring is transferred to the other by means of pinions, bearings, etc. Instead of this - cascading of the bar springs lying next to one another, the latter are grounded (.! never disproportionate transmission organs arranged in direct parallel connection to one another and firmly to one another at the ends tied together. The springs joined together to form a closed package and fastened to one another at the ends thus, when subjected to torsion, form a spring unit that has the characteristics of a Has torsion bar, but with the differences. dal! this in a simple way ' spring bars arranged next to one another have similar properties as several Bar springs arranged one above the other or next to one another are round, square or polygonal or tubular cross-section, to the common effect of which those avoided here Transmission organs, such as pinions, Bearings, etc., are required.

Durch diese Anordnung der Federstäbe ist es möglich, auch bei kurzer Baulänge des Fefk-relementes, wie es eine Fräswalze zur Bedingung macht, eine beliebig weiche Federung und einen großen Drehungswinkel von beispielsweise50- zu erhalten. Da auch leichte Herstellbarkeit und geringes Gewicht gewährleistet sind, ist in dieser Anordnung ein Fort- ] schritt zu erblicken.This arrangement of the spring bars makes it possible, even with a short length of the Fefk-element, as a milling drum requires, any soft suspension and a large angle of rotation of for example 50- to get. There also light ones Manufacturability and low weight are guaranteed, is a progress in this arrangement] step to behold.

In der Abbildung ist ein Aatsführungsbeispiel dargestellt. Die Qucrsehnittszeiehnung .1-11 läl.H die Anordnung der blattförmigen Federstäbe erkennen. Die Anzahl und J!reite der Blattstähe ist derart bemessen, da!.! sich ein quadratischer Querschnitt des Paketes ergibt. Dieses Blattfederpaket c ist in einer auf der Fräswelle d befindlichen Halterung h fest eingespannt und wird durch die Scheibe a am Herausgleiten gehindert. Am andern Ende ist 4S sie vermittels der Buchse / in einer gleichfalls auf der Fräswelle befestigten Halterung c drehbar gelagert. An dem freien überstehenden Ende ist in bekannter Weise die Fräshaue g aufgesteckt und durch den Stift // gesichert. Wird die Haue g gedreht, so überträgt sich die Drehung auf alle Federstäbe zu gleicher Zeit.An example of implementation is shown in the figure. The cross- sectional drawing .1-11 läl.H recognize the arrangement of the leaf-shaped spring bars. The number and width of the blade thickness is such that!.! a square cross-section of the package results. This leaf spring package c is firmly clamped in a holder h located on the milling shaft d and is prevented from sliding out by the disk a. At the other end it is supported by means of the sleeve / in a likewise mounted on the milling shaft holder rotatably 4S c. At the free protruding end, the milling cutter g is attached in a known manner and secured by the pin //. If the pick rotated g, so the rotation is transferred to all the spring rods at the same time.
