Verfahrensgemäß wird zur Herstellung der Verbindung zwischen den zwei Körpern, zuerst mindestens ein Körper im Bereich der herzustellenden Verbindung mit einer die Tribokorrosion einschränkenden bzw. verhindernden und einen Kraftschluss und Mikroformschluss gewährleistenden Schicht versehen und anschießend eine Pressverbindung zwischen beiden Körpern erzeugt.According to the method is for Making the connection between the two bodies, at least one first body in the area of the compound to be produced with a tribo-corrosion restrictive or preventing and ensuring a frictional connection and microforming Provided layer and anschießend creates a press connection between the two bodies.
Zur Herstellung einer Welle-Nabe-Verbindung, ist dabei zwischen Außendurchmesser der Welle und Innendurchmesser der Nabe ein Übermaß vorhanden, und die Nabe wird an ihrem Innendurchmesser an mindestens einer ersten Kontaktfläche zur Welle und/oder die Welle an ihrem Außendurchmesser an mindestens einer zweiten Kontaktfläche zur Nabe mit der Schicht versehen und anschließend zwischen Welle und Nabe eine Pressverbindung hergestellt. Das Fügen erfolgt in Form einer Querpressverbindung als Schrumpf-, Dehn-, Schrumpf-Dehnverbindung oder in Form einer Längspressverbindung, wobei die Nabe in Längsrichtung der Welle auf den Außendurchmesser der Welle unter Bestehen eines Übermaßes geschoben wird).to Production of a shaft-hub connection, is between outer diameter The shaft and inner diameter of the hub are oversized, and the hub becomes at its inner diameter at least a first contact surface to the shaft and / or the shaft at its outer diameter at least a second contact surface to the hub with the layer provided and then between Shaft and hub made a press connection. The joining takes place in the form of a transverse press connection as a shrinkage, expansion, shrinkage-expansion connection or in the form of a longitudinal press connection, with the hub in the longitudinal direction the shaft on the outside diameter pushed the shaft under the existence of an excess becomes).
Die mit der Schicht zu versehenden Flächen der Körper werden vor dem Aufbringen der Schicht durch Vorspülen mit Wachstumskeimen versehen, die die Bildung einer feinkristallinen Schicht begünstigen.The With the layer to be provided surfaces of the body are before applying the layer by pre-rinsing provided with growth germs, which is the formation of a finely crystalline Favor layer.
Weiterhin wird die Schicht vor dem Herstellen der Verbindung dehydratisiert. Das Übermaß zwischen Welle und Nabe beträgt vor dem Aufbringen der Beschichtung in der Regel 20 μm bis 80 μm bezogen auf einen Pressfugendurchmesser von 30 mm. Alternativ zur Längspressverbindung ist die Verbindung auch durch Schrumpfen oder Dehnen herstellbar.Furthermore, the layer before the manufacture dehydrated the compound. The excess between the shaft and hub before application of the coating is usually 20 microns to 80 microns based on a press joint diameter of 30 mm. As an alternative to the longitudinal press connection, the connection can also be produced by shrinking or stretching.
Es hat sich überraschenderweise gezeigt, dass durch die Verwendung einer Beschichtung in Form einer Manganphosphatierung, die Huréaulith enthält, eine hohe Sicherheit gegen ein Verschieben beider Bauteile gewährleistet ist.It has surprisingly shown by the use of a coating in the form of a Manganese phosphating containing huréaulith, one high security against shifting of both components guaranteed is.

die Manganphosphatschicht S sind die Rauhigkeitsspitzen der Bauteile
Es wurde durch zahlreiche Versuchsreihen überraschender Weise nachgewiesen, dass eine Manganphosphatschicht erstmalig als „Übertragungselement" einer Pressung/Pressverbindung zwischen den angrenzenden metallischen Bauteilen eingesetzt werden kann und insbesondere bei Wellen-Naben-Verbindungen dazu geeignet ist, hohe Drehmomente zu übertragen und Tribokorrosion/Passungsrost zu verhindern. Es ist weiterhin erstmalig möglich, die erfindungsgemäße Verbindung bei Flächenpressungen einzusetzen, wobei dann eine hohe Verschiebesicherheit gewährleistet wird und ebenfalls Tribokorrosion/Passungsrost vermieden werden kann.It was surprisingly proven by numerous series of experiments, that a manganese phosphate layer for the first time as a "transfer element" of a pressing / press connection between the adjacent metallic components can be used and especially suitable for shaft-hub connections to high torques transferred to and to prevent tribocorrosion / fretting corrosion. It is still possible for the first time the compound of the invention at surface pressure use, in which case ensures a high displacement safety and also tribocorrosion / fretting corrosion is avoided can.
