Description

  

  Lager aus     Kunststoff    und Verfahren zur Herstellung desselben.    Es ist bekannt, Maschinenlager     insbeson-           < lere    von Walzwerken und dergleichen aus       Kunststoff,    Kunstharzen und dergleichen her  zustellen, die gegenüber Lagern aus Metall       vielfache    Vorteile bieten. Die Gleitfähigkeit  der Lager aus Kunststoff wird durch übliche       Schmiermittel    oder     beispielsweise    bei     Walz-          inasehinen    durch Wasser erzielt.  



  Die Erfindung betrifft eine     Verbesserung     derartiger Lager aus     Kunststoff    und besteht  darin, dass das Lager mindestens ein     Gleit-          inittelzusatz    enthält. Das Verfahren zur Her  stellung des     Kunststofflagers    zeichnet sieh  dadurch aus, dass dem     Kunststoff        mindestens     ein     ("leitmittel        zugesetzt    wird. Vorzugsweise  wird dem Kunststoff Graphit     zugesetzt.     



  Es hat. sieh herausgestellt,     da.ss    nach einem       derartigen    Verfahren hergestellte     Kunststoff-          laz;er#    eine besonders grosse Gleitfähigkeit und       i        Abriebfähigkeit    besitzen und die     Reibungs-          verluste    und der Kraftbedarf stark     herabge-          set7t    werden. Ausser der hierdurch erzielten  Ersparnis ergibt sieh der weitere Vorteil, dass  besondere     Gleitmittel    wie Öl oder     Wasser        ent-          hehrlieh    werden.

    



  Dieser Umstand ist namentlich bei solchen  Maschinen und     Vorrichtungen    von grossem  Vorteil, bei denen die Lagerstellen     schwer            zugänglich    sind oder infolge unsachgemässer  Behandlung das Schmieren in der Regel un  terlassen wird, was vielfach für     lanJwirt-          sehaftliche    oder     hausw'irtsehaftliehe    Maschi  nen und Geräte zutrifft, bei denen infolge  ungenügender     Schmierung    ein besonders  grosser Verschleiss an den     Lagerstellen    ent  steht.  



  Der     Zusatz    von Gleitmitteln wie Graphit  zu dem     Kunststoff        erfolgt    in geeigneten Men  gen. Die Zeichnung     stellt    als eine     Ausfüh-          rungsform    der     Erfindung    eine Schale eines  Maschinenlagers dar.



  Plastic bearings and method of making the same. It is known to manufacture machine bearings, in particular of rolling mills and the like, made of plastic, synthetic resins and the like, which offer many advantages over bearings made of metal. The sliding ability of the bearings made of plastic is achieved by means of conventional lubricants or, for example, in the case of roller bearings, by water.



  The invention relates to an improvement of such bearings made of plastic and consists in the bearing containing at least one lubricant additive. The method for manufacturing the plastic bearing is characterized in that at least one ("conductive agent" is added to the plastic. Graphite is preferably added to the plastic.



  It has. It has been shown that plastic sheets produced by such a process have particularly good sliding properties and abrasion properties, and the friction losses and the power requirement are greatly reduced. In addition to the savings achieved in this way, there is the further advantage that special lubricants such as oil or water are not required.

    



  This circumstance is particularly of great advantage in those machines and devices in which the bearing points are difficult to access or in which lubrication is generally neglected due to improper handling, which is often the case for agricultural or domestic machines and devices which, due to insufficient lubrication, cause particularly high wear at the bearing points.



  Lubricants such as graphite are added to the plastic in suitable quantities. The drawing represents a shell of a machine bearing as an embodiment of the invention.
