Description

Die. 'llalltelhülse@ti der Druckwalzen der Streck-von spinntnaschinen bestehen in der Regel ,aus beiderseits offenen oder einseitig geschlossenen hohlzylindrischen Rollen, die drehbar auf der fest "e lagerten Achse sitzen und gegen 1, T<.:ren eine unbeabsichtigte axiale Verscliiebung durch eingesprengte Fedei-riitgc gesichert sind, die ein Abstreifen und Wiederaufbringen der Hülsen zutn Zwecke der Reinigung und Erlicuvrung des Belages gestatten. Uci den bisher bekannten Druckwalzen sind diese Federringe in Rillen der Laufflächen der Rollen und Zapfen eingelegt, also unmittelbar an der Lagerstelle angebracht und werden dadurch verh;iitnistn'siLiig rasch abgenutzt; auch macht hierbei infolge des meist ziemlich geringen Durchmessers der kollenbohrung die genaue Fixierung der Rollen nicht selten Schwierigkeiten.The. 'llalltelhülse @ ti, the pressure rollers of the stretching of spinntnaschinen consist as a rule, from both sides open or closed on one side hollow cylindrical rollers which rotatably superimposed on the fixed "e axis sit and against 1, T <.: ren inadvertent axial Verscliiebung by disseminated Spring rings are secured, which allow the sleeves to be stripped off and reapplied for the purpose of cleaning and clearing the covering. In the previously known pressure rollers, these spring rings are inserted into grooves in the running surfaces of the rollers and journals, i.e. they are attached directly to the bearing point and are thereby Worn relatively quickly; here too, due to the usually rather small diameter of the barrel bore, the precise fixation of the rollers often causes difficulties.

Der griillere Ring kann auch einen starken axialen Schuhe aufnehmen, so d.aß die Gefahr eines Herausfallens der Mantelliiilse verringert ,e ird. 'Der Federring wird an dieser Stelle erliehli;li geringer l cansl>rucht als bei seiner lnbringung im der Lagerstelle, -,wodurch die Lebensdauer und Ztivet-has,igkeit der \"erbindung erhöht werden. Schließlich bietet der Federring hier zugleich eine "virksatne Sicherung gegen ein Eindringen von \'ertivt-cinigungen, insbesimdereFaserflug, zti derLauffluche der Mantelhülse, wodurch gleichfalls die H)etriebssicherlieit und die Lebensdauer erhöht und zcitraul>etide Reinigungsarbeiten erspart werden.lki the L) ruckw @ iizc according to the invention sits the II, e <crriitg not inside the roller bearing, should- (Icrn is auflen on your thrust collar the Roller axis attached and engages in this overlapping hollow cylindrical Protrusion of the N'Iantelhülse. 1) a the start-up collar a correspondingly larger one 1) has tirchntesser than the bearing journal, four spring washers also have a larger one Diameter, through which a better and more precise fixation is made possible. Of the The griller ring can also accommodate a strong axial shoe, thus reducing the risk falling out of the mantle fibers is reduced. 'The spring washer is on This place was granted less cansl than when it was placed in the Bearing point, which increases the service life and availability of the connection will. After all, the spring ring also offers a "virksatne security" Against the penetration of \ 'ed-cinemas, in particular fiber flight, for example the curses the jacket sleeve, which also ensures reliability and service life increased and zcitraul> etide cleaning work can be saved.

Ein Ausführungsbeispiel einer Druckwalze nach der Erfindung ,ist in der Zeichnung in schematischer Foren dargestellt. Mit i sind die Mantelhülsen bezeichnet, mit 2 die als Gleitlager für diese dienenden Zäpfen der Druckwalzenachse 3. d sind die Anlaufbunde der Zapfen, 5 die hohlzylindrischen Verlängerungen der Mantelhülsen, mit welchen clicsetiti an sich bekannter Weise die Anlaufbunde übergreifen, uni das Eindringen von Flug ztt den .a-erflächen zu erschweren.An embodiment of a pressure roller according to the invention is shown in FIG the drawing shown in schematic forums. The jacket sleeves are denoted by i, with 2 which serve as plain bearings for these cones of the printing roller axis 3. d the run-up collars of the pins, 5 the hollow cylindrical extensions of the jacket sleeves, with which clicsetiti, in a known manner, the start-up bundles overlap, uni to make the penetration of air into the surface more difficult.

Zwischen der Oberfläche der Bunde 4. und der Innenfläche der Hohlzylinder 5 liegt je ein federnder Sprengring 6, durch avelchen die Mantelhülse gegen axiale Verschiebung geschützt wird. Zutn Zwecke der Reinigung kann sie entgegen der Wirkung dieses Ringes nach außen abgestreift werden.Between the surface of the collar 4. and the inner surface of the hollow cylinder 5 is a resilient snap ring 6, by avelchen the jacket sleeve against the axial Shift is protected. For the purpose of cleaning it can counteract the effect this ring are stripped to the outside.

Zur leichteren Aufbringung des Federringes 6 auf den Bund d ist dieser an seinem Auflaufende 1iei 7 leicht konisch altgerundet.For easier application of the spring ring 6 on the collar d is this at its run-up end 1iei 7 slightly conical old-rounded.
