Description

Wellenlager Wellenlager aus Metall, auch wenn sie zum leichten Beheben von Abnutzungsschäden an der Lauffläche mit austauschbaren Metallbändern ausgekleidet sind, besitzen noch verschiedene Nachteile. So unterliegen sie im allgemeinen einem nicht unbeträchtlichen Abrieb, sie sind korrosionsempfindlich, sie bedürfen laufend einer Schmierung mit Ölen oder Fetten, und der Lauf der Wellen ist oftmals verhältnismäßig laut. Man hat deshalb auf mannigfache Weise versucht, diese Nachteile durch den Einsatz von Kunststoffen zu mindern oder auszuschalten. Da die Kunststoffe schlechte Wärmeleiter sind, kommt es jedoch bei massiven Kunststofflagern leicht zu Überhitzungen an den Laufflächen. Man ist deshalb' auch schon dazu übergegangen, die Lagerschalen aus Kunststoffen mit Metalleinlagerungen oder aus porösen Metallen mit Kunststoffeinlagerungen herzustellen. Derartige Wellenlager vermögen aber noch nicht, alle Nachteile zu überwinden. Ferner hat man Wellenlager aus Metallen mit dünnen Kunststoffauskleidungen, z. B. mit Filmen, an der Lauffläche versehen.Shaft bearings Shaft bearings made of metal, even if they are for easy repair from wear damage to the tread lined with replaceable metal strips still have various disadvantages. So they are generally subject to one not inconsiderable abrasion, they are sensitive to corrosion, they require constant lubrication with oils or greases, and the movement of the shafts is often proportionate according to. Attempts have therefore been made in many ways to overcome these disadvantages Reduce or eliminate the use of plastics. Because the plastics are bad Are heat conductors, but massive plastic bearings can easily overheat on the treads. That’s why they’ve already gone over to the bearing shells Made of plastics with metal inclusions or of porous metals with plastic inclusions to manufacture. Such shaft bearings are not yet capable of all of the disadvantages overcome. There are also shaft bearings made of metals with thin plastic linings, z. B. with films, provided on the tread.

Es wurde nun gefunden, daß man Lager aus Metall mit einer Kunststoffauskleidung mit besonders geringer Reibung und, infolge außerordentlich geringen Abriebs, mit überraschend hoher Lebensdauer dadurch erhält, daß man zur Auskleidung gereckte bzw. gewalzte Kunststoffbänder oder -filme verwendet.It has now been found that one can use metal bearings with a plastic lining with particularly low friction and, as a result of extremely low abrasion, with A surprisingly long service life is obtained by stretching them for the lining or rolled plastic tapes or films are used.

Es ist zwar bekannt, daß gereckte bzw. gewalzte Kunststofffolien oder -bänder eine höhere Reißfestigkeit als nicht gereckte besitzen. Es war jedoch nicht zu erwarten, daß die Reibung und der Abrieb bei gereckten Filmen oder Bändern erheblich geringer sind als bei nicht gereckten.It is known that stretched or rolled plastic films or -Tapes have a higher tear resistance than non-stretched ones. However, it wasn't the friction and abrasion of stretched films or tapes can be expected to be significant are lower than with non-stretched.

Die Filme oder Bänder können in an sich bekannter Weise eine Dicke bis hinunter zu 0,1 mm und weniger besitzen. Für viele Zwecke liegen geeignete Dicken z. B. etwa zwischen 0,5 und 2 mm.The films or tapes can have a thickness in a manner known per se down to 0.1 mm and less. Suitable thicknesses are suitable for many purposes z. B. approximately between 0.5 and 2 mm.

Als Kunststoffe kommen beispielsweise in Frage Polykondensationsprodukte, wie Polyamide und Polyurethane, ferner Polymerisationsprodukte, wie das als Gleitmittel an sich bekannte Polytetrafluoräthylen, sowie Polymonochlortrifluoräthylen. Der benutzte Werkstoff selbst ist nicht Gegenstand des Schutzes.Polycondensation products can be used as plastics, for example, such as polyamides and polyurethanes, and also polymerization products such as lubricants known polytetrafluoroethylene and polymonochlorotrifluoroethylene. Of the The material used itself is not subject to protection.

Das Recken oder Walzen der Filme oder Bänder kann bei Temperaturen unterhalb des Erweichungspunktes des Kunststoffes, z. B. zwischen Raumtemperatur und etwa 250°, vorzugsweise zwischen etwa 50 und etwa 200°, z. B. mit Hilfe eines Kalanders, erfolgen.The stretching or rolling of the films or tapes can take place at temperatures below the softening point of the plastic, e.g. B. between room temperature and about 250 °, preferably between about 50 and about 200 °, e.g. B. with the help of a Calender.

Bei der Auskleidung von Lagerschalen ist es besonders vorteilhaft, ein erfindungsgemäßes Kunststoffband in an sich bekannter Weise lose in die Lauffläche der Welle einzulegen und den Streifen z. B. an der der Drehrichtung der Welle zugewandten Seite festzuklemmen (s. Zeichnung). Auf diese Weise läßt sich das Kunststoffband leicht austauschen.When lining bearing shells, it is particularly advantageous to a plastic tape according to the invention loosely in the tread in a manner known per se insert the shaft and z. B. facing the direction of rotation of the shaft Clamp the side (see drawing). In this way, the plastic tape easily exchange.
