Abstract

In den letzten Jahren hat der Einsatz von wartungsfreien Lagern enorm zugenommen. Allerdings ist der erfolgreiche Einsatz nur durch fachliche Beratung zu erreichen.PTFE zeichnet sich besonders, bei niederen Gleitgeschwindigkeiten und hohen, bis sehr hohen Drücken, aufgrund seines niederen Reibungskoeffizienten aus.Auf Grund der antiadhäsiven Eigenschaften von PTFE sind schwierige und kostenaufwendige Herstellungsmethoden notwendig. Diese Nachteile werden durch die vorzüglichen Eigenschaften , die bis zum verschleißfreien Einsatz führen können, aufgefangen.Um diese Nachteile zu umgehen wird eine mechanische Befestigung in Form einer Verspannung vorgeschlagen. Die Verspannung kann durch Schrumpfung, durch Druckstücke oder auch durch Federringe erfolgen.In recent years, the use of maintenance-free bearings has increased enormously. However, successful use can only be achieved with expert advice.PTFE is particularly notable for low sliding speeds and high to very high pressures, due to its low coefficient of friction. Due to the anti-adhesive properties of PTFE, difficult and costly production methods are necessary. These disadvantages are offset by the excellent properties that can lead to wear-free use. To avoid these disadvantages, a mechanical fastening in the form of a bracing is proposed. The clamping can be done by shrinkage, by pressure pieces or by spring washers.

Description

Die Erfindung bezieht sich auf die Herstellung von wartungs- und schmierungsfreien Gleitlager, für rotierende Bewegungen, wobei die Polymerisierte Tetra Fluorierte Ethhylen Gewebegleitfläche PTFE nur durch eine mechanische Befestigung erfolgt.The invention relates to the production of maintenance-free and lubrication-free plain bearings, for rotary movements, wherein the polymerized Tetra Fluorinated ethylene fabric sliding surface PTFE only by a mechanical attachment.

Die selbstschmierende PTFE Gewebefläche befindet sich nicht auf dem stationären Teil, Bohrung sondern auf dem bewegten Teil, Welle bzw. Achse.The self-lubricating PTFE fabric surface is not located on the stationary part, bore but on the moving part, shaft or axle.

Bei den bisher bekannt gemachten schmierungslosen Lager, ins besonders schmierungslosen PTFE-Gewebegleitlager, kommt nur eine geringe Fläche als tragendes schmierungsloses Gleitelement zur Geltung. Der Herstellungsaufwand ist hoch, darum teuer, kompliziert. und damit Fehler behaftet.In the previously made lubrication-free bearings, the particularly lubrication-free PTFE fabric sliding bearing, only a small area comes as a bearing lubrication-free sliding advantage. The production cost is high, therefore expensive, complicated. and thus flawed.

Diese Nachteile werden durch die angezeigte Erfindung der mechanischen Befestigung , sowie durch die vollgenutzte schmierungslose PTFE Gleitfläche vermieden.These disadvantages are avoided by the indicated invention of the mechanical attachment, as well as by the fully used lubrication PTFE sliding surface.

Eine Lagerung hat die Aufgabe ein bewegliches Maschinenelement mit einem ruhenden Maschinenelement zu verbinden. Die Verbindungstelle soll. dabei reibungsarm, idealerweise reibungsfrei sein.A bearing has the task of connecting a movable machine element with a stationary machine element. The connection point should. while friction, ideally frictionless.

Um die Reibung zwischen den Elementen zu vermindern bedarf es einer Gleitschicht. Diese Gleitschicht kann z.B in flüssiger Form, Schmierfilm„ aber auch in fester Form als selbstschmierendes PTFE Gewebe sein.In order to reduce the friction between the elements, a sliding layer is required. This sliding layer can be, for example, in liquid form, lubricating film "but also in solid form as a self-lubricating PTFE fabric.

Bei Trockenlauflager ist ab der ersten Umdrehung ein Abrieb (Verschleiß) vorhanden. Dabei unterscheidet man Einlauf- und Dauerverschleiß. Bei PTFE Lager ist der Einlaufabrieb eine wesentliche Voraussetzung um einen niederen Reibungskoeffizientenwert zu erreichen . Die PTFE-Teilchen müssen Haftmöglichkeiten auf der Gegenseite der Lauffläche finden um dort einen Schmierfilm aufbauen zu können,. Der niedere Reibungskoeffizient entsteht erst dann, wenn PTFE auf PTFE läuft.For dry-running bearings, abrasion (wear) is present from the first revolution. A distinction is made between running-in and long-term wear. In the case of PTFE bearings, run-in abrasion is an essential prerequisite for achieving a low friction coefficient value. The PTFE particles must find adhesion possibilities on the opposite side of the tread in order to be able to build up a lubricating film there. The low coefficient of friction occurs only when PTFE is running on PTFE.

Man kann einen Einlaufverschleiß durch Erstschmierung verzögern und auch dadurch einen Dichtungseffekt erreichen.One can delay an inlet wear by first lubrication and thereby also achieve a sealing effect.

Bei bestimmten Voraussetzungen ist es sogar möglich einen Abrieblosenzustand zu erreichen Anlage 2 Seite 4 Anlage3 Seite 3, Seite 9,
PTFE als Trockenschmiermittel, PTFE-Gewebe ist eine Herstellungsabart, weist den niedersten Reibungskoeffizienten aller Feststoffe auf. Bei hohen Drücken und geringer Gleitgeschwindigkeit ist ein Reibungskoeffizient wie bei üblicher hydro-dynamischer Schmierung (µ = 0,04 bis 0,08)zu erreichen. Es kommt zu keinem stick-slip Effekt.(Ruckgleiten) Bei unverhältnismäßig hohen Drücken tritt kein festfressen auf. Bei statischen Drücken von p < 4200 kp/cm2 tritt bei PTFE-Geweben kein Kaltfluss auf.Under certain conditions, it is even possible to achieve an abrasion-free condition. Appendix 2 Page 4 Appendix 3 Page 3, page 9,
PTFE as a dry lubricant, PTFE fabric is a Herstellabart, has the lowest coefficient of friction of all solids. At high pressures and low sliding speed, a coefficient of friction can be achieved as with conventional hydro-dynamic lubrication (μ = 0.04 to 0.08). There is no stick-slip effect. (Stick-slip) At disproportionately high pressures no seizure occurs. At static pressures of p <4200 kp / cm 2 , no cold flow occurs with PTFE fabrics.

Bei Brückenlager werden virginale PTFE-Platten * mit 420kg/cm2 ohne Kaltfluss, belastet.For bridge bearings, virgin PTFE plates * are loaded with 420kg / cm 2 without cold flow.

Bei einem p.v-Wert von 10 kp/cm2/mm/s ist kein messbarer Verschleiß vorhanden. Anlage3 Seite 9At a pv value of 10 kp / cm 2 / mm / s no measurable wear is present. Annex3 page 9

Diese exzellenten Eigenschaften kann man nur durch eine werkstoffgerechte Verarbeitung erreichen. Hartverchromung. und polierte Flächen wirken kontraproduktiv..
* Ungefültes PTFE = Virginales PTFE
Gefülltes PTFE = PTFE mit Zusatzstoffen (Füllung) z.B. Glas, Graphit, Kohle usw.These excellent properties can only be achieved by material-appropriate processing. Hard chrome plating. and polished surfaces are counterproductive ..
* Unfilled PTFE = virgin PTFE
Filled PTFE = PTFE with additives (filling) eg glass, graphite, carbon etc.

Mit der vorliegenden Erfindung sollen die bisherigen Herstellschwierigkeiten„ von PTFE-Gleitschichten vermieden werden. Die bisher üblichen Ausführungen von Gewebegleitlager hatten den Nachteil einer schwierigen und aufwendigen Herstellmethode.With the present invention, the existing manufacturing difficulties "of PTFE sliding layers are to be avoided. The hitherto usual designs of fabric slide bearings had the disadvantage of a difficult and expensive production method.

Aufgrund der anti-adhäsiven Eigenschaften von PTFE ist für die Verklebung eine Vorbehandlung (ätzen) notwendig. Eine einwandfreie Verklebung ist. aber schwierig durchzuführen. Die meisten Lagerschäden treten durch Verarbeitungsfehler auf.Due to the anti-adhesive properties of PTFE, pre-treatment (etching) is necessary for the bonding. A perfect bond is. but difficult to perform. Most bearing damage occurs due to processing errors.

Für die Gestaltung der Gewebegleitflächen werden Hilfsstoffe (Harze) benötigt.Auxiliaries (resins) are required for the design of the fabric sliding surfaces.

Das PTFE-Gewebe stellt eine Wärmeisolation, der Nachteil aller Kunststofflager, dar. Durch das Stützgewebe und den Kleber entstehen zusätzliche Wärmeisolationsschichten. Wenn auch nicht mit der höchstmöglichen Lagertemparatur gefahren wird, so kann durch einen Wärmestau schnell die Harzgrenztemparatur erreicht werden die dann zur Zerstörung des Lagers führen würde Durch die Kunstharzschicht wird auch die Temparatureinsatzgrenze herab gesetzt. Durch Schwingungsbelastungen könnte eine weitere Beschädigung der Harzschicht hervorgerufen werden. Der PTFE-Gewebetraganteil ist vermindert.The PTFE fabric is a thermal insulation, the disadvantage of all plastic bearings dar. The support fabric and the adhesive creates additional heat insulation layers. Even if the highest possible storage temperature is not used, a heat build-up can quickly reach the resin boundary temperature that would then destroy the bearing. The synthetic resin layer also lowers the temperature limit. Vibration loads could cause further damage to the resin layer. The PTFE fabric content is reduced.

Man erreicht durch die mechanische Befestigung der TEFLON - Gewebegleitfläche wesentliche Vorteile gegenüber den bisher üblichen Ausführungen von Gewebegleitlager.Due to the mechanical attachment of the TEFLON fabric sliding surface, significant advantages are achieved over the hitherto usual designs of fabric plain bearings.

Es ist keine Verklebung, kein Stützgewebe, keine Kunstharzschicht, kein Mischgarn, keine Baumwoll- oder Glasgewebeunterseite. notwendig. Es entfallen auch schwierige Textilherstellungsmethoden (Velour-Samtgewebe. Filze, Vernadeln udgl.) Durch die vereinfachte Herstellungsmethode, wie aufschrumpfen, PTFE-Gewebe schrumpft um 4% bis 5%, in Verbindung mit rauherOberfläche und event. einen zusätzlichen Preßvorgang oder einen Spanndorn, werden Verarbeitungsfehler vermieden. Es kommt die ganze, reine PTFE-Gleitschicht zum tragen.It is not a bond, no supporting fabric, no synthetic resin layer, no blended yarn, no cotton or glass fabric underside. necessary. It also eliminates difficult textile manufacturing methods (velor velvet fabrics, felts, needling, etc.) Through the simplified manufacturing method, such as shrinking, PTFE fabric shrinks by 4% to 5%, in conjunction with rough surface and event. an additional pressing operation or a mandrel, processing errors are avoided. It comes the whole, pure PTFE sliding layer to wear.

Für die Bohrung ist keine feingeschlichtete oder geschliffene Oberfläche erforderlich. Eine geschlichtete Oberfläche ca. Ra= 16 µ DIN ISO 1302 ist ausreichend, dadurch ist auch ein Herstellungskostenvorteil gegebenNo finely polished or ground surface is required for the hole. A glazed surface approx. R a = 16 μ DIN ISO 1302 is sufficient, thereby also a manufacturing cost advantage is given
