Title (DE) GELENKKETTE MIT NITRIERTER LAGERFLÄCHE MIT OXIDATIONSSCHICHT
(EN) LINK CHAIN HAVING NITRIDED BEARING FACE WITH OXIDATION COATING
(FR) CHAÎNE ARTICULÉE À SURFACE D'APPUI NITRURÉE COMPORTANT UNE COUCHE D'OXYDATION
Abstract:
(DE) Die Erfindung bezieht sich auf eine Gelenkkette (1) mit jeweils über ein Kettengelenk (2) miteinander verbundenen Kettengliedern, wobei sich jeweils ein Gelenkbolzen ( 3 ) zum Bilden eines Kettengelenks durch mindestens eine Gelenköffnung erstreckt und eine Lagerfläche der Gelenköffnung und/oder des Gelenkbolzens eine nitrierte Oberflächenschicht aufweist , wobei die nitrierte Oberflächenschicht der Lagerfläche eine äußere Oxidationsschicht zum Verbessern der Verschleißbeständigkeit des Kettengelenks aufweist .
(EN) The invention relates to a link chain (1) having chain members which are in each case connected to one another by means of a chain link (2), with in each case one link pin (3) extending through at least one link opening in order to form a chain link, and with a bearing face of the link opening and/or of the link pin having a nitrided surface coating, wherein the nitrided surface coating has an outer oxidation coating in order to improve the wear-resistance of the chain link.
(FR) L'invention concerne une chaîne articulée (1) dont les éléments sont reliés par des articulations (2). Une articulation est formée par un axe (3) traversant au moins une ouverture d'articulation. Une surface d'appui de l'ouverture d'articulation et/ou de l'axe d'articulation est pourvue d'une couche superficielle nitrurée, laquelle comporte une couche d'oxydation externe pour augmenter la résistance à l'usure de l'articulation de la chaîne.
