Offenbarung der ErfindungDisclosure of the invention
Vorteile der ErfindungAdvantages of the invention
Die erfindungsgemäße Vorrichtung mit den Merkmalen gemäß Anspruch 1 hat den Vorteil, dass sich die benötigten Lager bei ähnlicher Dauerhaltbarkeit kostengünstiger erzeugen lassen.The inventive device with the features according to claim 1 has the advantage that the required bearings with similar durability produce less expensive.
In den abhängigen Ansprüchen sind vorteilhafte Ausgestaltungen und Weiterbildungen der erfindungsgemäßen Vorrichtung angegeben.In the dependent claims are advantageous embodiments and further developments of the device according to the invention specified.
Durch die Ausgestaltung nach Anspruch 2 wird der Vorteil erzielt, dass sich die Montage eines separat hergestellten Gleitlagers erübrigt.By the embodiment according to claim 2, the advantage is achieved that the installation of a separately manufactured plain bearing is unnecessary.
Die Ausgestaltung nach Anspruch 3 hat den Vorteil, dass sich die Gleitlager nach eingetretenem Verschleiß als komplette Baueinheit in einer Werkstatt leicht erneuern lassen.The Embodiment according to claim 3 has the advantage that the plain bearings after wear occurred as a complete unit Have it replaced in a workshop.
Die Ausgestaltung nach Anspruch 4 hat den Vorteil, dass sich die Zerklüftung besonders leicht und schnell erzeugen lässt, ohne die feste Anbindung der Gleitschicht zu gefährden.The Embodiment according to claim 4 has the advantage that the fracture very easy and fast to produce, without the fixed Connection of the sliding layer to endanger.
Die Ausgestaltung nach Anspruch 5 hat den Vorteil, dass sich die Zerklüftung leicht und schnell erzeugen lässt, in dem die sie bildenden Eintiefungen nur in den besonders gefährdeten Bereiche tiefer als in den übrigen Bereichen eingearbeitet werden.The Embodiment according to claim 5 has the advantage that the fracture produce easily and quickly, in which they are forming Indentations only in the most vulnerable areas be incorporated deeper than in the other areas.
Die Ausgestaltung nach Anspruch 6 hat den Vorteil, dass sich die Haftfestigkeit der Gleitschicht in der Zerklüftung weiter verbessert.The Embodiment according to claim 6 has the advantage that the adhesive strength the sliding layer in the fracture further improved.
Die Ausgestaltung nach Anspruch 7 hat den ebenfalls den Vorteil einer schnellen Herstellbarkeit. Durch die Verfügbarkeit von Eintiefungen, die in gegenseitigen Abständen angeordnet sind, gelingt es einen hinreichende Haftung der Gleitschicht in der Zerklüftung zu erzeugen, die normalen Ansprüchen genügt.The Embodiment according to claim 7 also has the advantage of a fast manufacturability. Due to the availability of Depressions arranged at mutual intervals are successful, sufficient adhesion of the sliding layer in To produce the fracture that meets normal requirements.
Die Ausgestaltung nach Anspruch 8 hat den Vorteil, dass sich der Herstellung der Zerklüftung noch mehr beschleunigt ohne die Haftung der Gleitschicht direkt zu gefährden.The Embodiment according to claim 8 has the advantage that the production the fracture accelerates even more without the adhesion directly endanger the sliding layer.
Die Ausgestaltung nach Anspruch 9 hat den Vorteil einer besonders einfachen dass die Gleitschicht auf ihrer dem relativ bewegten Teil zugewandten Oberfläche die wünschenswerte Maßhaltigkeit bereits im Anschluss an die Anformung weitestgehend aufweist.The Embodiment according to claim 9 has the advantage of a particularly simple that the sliding layer facing on its the relatively moving part Surface the desirable dimensional stability already has following the Anformung as far as possible.
Die Ausgestaltung nach Anspruch 10 hat den Vorteil, dass sich die Maßhaltigkeit weiter verbessert, was für die Verbesserung der Dauerhaltbarkeit von großem Vorteil ist.The Embodiment according to claim 10 has the advantage that the dimensional accuracy further improved, indicating the improvement of durability is of great advantage.

Reparaturfähigkeit wird erleichtert, wenn die Gleitschicht
PTFE und PEEK lassen sich nur schwierig mit ebenen Oberflächen verkleben. Die in der gegenseitigen Berührungszone angeordnete Zerklüftung unterstützt die gegenseitige Verklebung überraschender Weise derart gut, dass in der vorliegenden Anwendung auf einen Primer und ähnlich aggressive, gesundheitsgefährdende und teure Vorbehandlungen verzichtet werden und dennoch die erwünschte Haftfestigkeit erzielt werden kann. Die Zerklüftung umfasst zu diesem Zweck vorteilhaft zumindest einander durchschneidende Rillen. Sie stellt eine zusätzlich eine formschlüssige Verbindung der Fügepartner sicher.PTFE and PEEK are difficult to achieve with even surfaces stick together. The arranged in the mutual contact zone Cracking supports the mutual bonding more surprising Way so well that in the present application to a primer and similarly aggressive, harmful to health and expensive pretreatments are dispensed with and yet the desired Adhesive strength can be achieved. The fracture includes for this purpose advantageous at least intersecting each other Grooves. It also provides a positive fit Connection of joining partners sure.
Die Haftfestigkeit der Gleitschicht lässt sich verbessern, wenn die Zerklüftung Eintiefungen umfasst, die in den verschiedenen Teilbereichen eine voneinander abweichende Tiefe und/oder Breite haben.The Adhesive strength of the sliding layer can be improved, if the fracture includes recesses formed in the various Subareas a different depth and / or width to have.
Um die notwendige Haftfestigkeit zu erzielen, ist es nicht unbedingt erforderlich, dass die Zerklüftung in allen Teilbereichen der Gleitschicht übereinstimmend ausgebildet ist. Sie kann vielmehr in weniger belasteten Bereichen Eintiefungen umfassen, die in gegenseitigen Abständen voneinander über die Oberfläche verteilt sind und die im mittleren Bereich der Oberfläche größere Abstände voneinander haben als im Randbereich.Around it's not necessarily to achieve the necessary adhesive strength required that the fracture in all sections the sliding layer is designed to match. she can rather include depressions in less polluted areas, which are at mutual distances from each other the surface are distributed and those in the middle area the surface larger distances have each other as in the border area.
