Description

Mit Faserstoff verstärktes Kunststoffzahnrad Die Erfindung bezieht sich auf ein Kunststoffzahnrad, das mit Faserstoff verstärkt ist.Plastic gear reinforced with fiber material The invention relates to on a plastic gear that is reinforced with fiber.

Es ist bekannt, Hartgewebematerial, d. h. mit Imprägnierharz getränkte und verpreßte Textilfasern oder -gewebe für die Herstellung von Zahnrädern zu verwenden. Ferner hat man auch schon Zahnräder aus reinem thermoplastischem nicht faserförmigem Material, z. B. aus Polyamid, hergestellt, wobei die Fertigung im wesentlichen im Spritzgußverfahren oder spanabhebend erfolgte. Kunststoffräder aus thermoplastischem Material können durch Füllstoffe mechanisch verstärkt werden, jedoch entstehen dabei für die Verarbeitung erhebliche Schwierigkeiten.It is known to use hard tissue material, i.e. H. impregnated with impregnating resin and to use compressed textile fibers or fabrics for the manufacture of gears. Furthermore, one already has gears made of pure thermoplastic, non-fibrous Material, e.g. B. made of polyamide, the production being essentially Injection molding or machining took place. Plastic wheels made of thermoplastic Material can be mechanically reinforced by fillers, but this is the result significant difficulties for processing.

Die gestellte Aufgabe besteht darin, durch Fasern aus abgewandelten Naturstoffen mechanisch verstärkte Kunststoffzahnräder zu schaffen, die in einem einfachen Preßvorgang ohne Vorbehandlung der Faserstoffe und somit denkbar billig und rationell hergestellt werden können.The task at hand is to use fibers made from modified Natural materials to create mechanically reinforced plastic gears in one simple pressing process without pretreatment of the fibrous materials and therefore extremely cheap and can be produced efficiently.

Durch Anwendung ausreichend hoher Temperatur beim Verpressen erweicht das thermoplastische Fadenmaterial und dient als Bindemittel für den Verbund des Faser- und Fadenmaterials im Preßkörper. Dabei wird das Fasermaterial aus abgewandelten Naturstoffen, das meist hygroskopisch und besonders anfällig gegen chemische Einflüsse ist, weitgehend vom erweichten thermoplastischen Material umhüllt und geschützt.Softened by applying a sufficiently high temperature during pressing the thermoplastic thread material and serves as a binder for the composite of the Fiber and thread material in the pressed body. The fiber material is made from modified Natural substances that are mostly hygroscopic and particularly susceptible to chemical influences is largely enveloped and protected by the softened thermoplastic material.

Bei der Mitverwendung von synthetischem thermoplastischem Fadenmaterial können durch diesem zugesetzte Füllmittel die mechanischen Eigenschaften des Fadenmaterials verbessert werden. Zusätze an Gleitmitteln lassen sich besonders vorteilhaft homogen im synthetischen Fadenmaterial, insbesondere auf Polyamidbasis, verteilen.When using synthetic thermoplastic thread material This added filler can improve the mechanical properties of the thread material be improved. Additions of lubricants can be particularly advantageously homogeneous Distribute in the synthetic thread material, especially based on polyamide.

Durch Mitverwendung dieses Materials zum Aufbau mindestens eines Zahnradkranzes kann durch Auswahl und Herstellungsweise weitgehend den Erfordernissen beispielsweise bezüglich der mechanischen Festigkeit, der Widerstandsfähigkeit gegen chemisch bedingte Einflüsse und anderen Wünschen Rechnung getragen werden.By using this material to build at least one ring gear can largely meet the requirements, for example, by selection and production method in terms of mechanical strength, resistance to chemical factors Influences and other wishes are taken into account.

Als besonders geeignet hat sich ein Gewebe aus synthetischem Fadenmaterial auf der Basis von Polyamid erwiesen. Selbstverständlich kann auch anderes synthetisches Fadenmaterial, das auf Grund seiner physikalischen Eigenschaften als geeignet erscheinen kann, zum Aufbau solcher Kunststoffzahnräder Verwendung finden.A fabric made of synthetic thread material has proven to be particularly suitable based on polyamide. Of course, other synthetic materials can also be used Thread material that appears suitable due to its physical properties can be used to build such plastic gears.

Für bestimmte Zwecke ist es ausreichend, ein Mischgewebe aus synthetischem Fadenmaterial und abgewandelten Naturstoffen zu verwenden.For certain purposes it is sufficient to use a synthetic blend To use thread material and modified natural substances.
