A chain conveyor assembly having the combination of a polymeric material and a hard diamond-like coating at the frictional interface of the chain links. The conveyor chain preferably includes male and female links connected to one another by connector pins (20). The shaft of each connector pin (20) is coated with a diamond-like coating having high hardness, low friction and low wear characteristics. Opposite ends of the connector pins (20) are connected to the female link while the shaft (52) of the connector pin (20) passes through the male link. A polymeric bushing (18) is fitted to the male link in engagement with the shaft (52) of the connector pin (20). Accordingly, relative movement between the links occurs at the interface of the DLC connector pin (20) and the polymeric bushing (18).

L'invention concerne un ensemble convoyeur à chaînes présentant une combinaison d'un matériau polymère et d'un revêtement dur de type diamant sur l'interface de frottement des maillons des chaînes. Le convoyeur à chaînes comprend, de préférence, des maillons mâles et femelles connectés les uns aux autres par des broches (20). La tige de chaque broche (20) est recouverte d'un revêtement de type diamant présentant une grande dureté et des caractéristiques de frottement et d'usure faibles. Les extrémités opposées des broches (20) sont reliées au maillon femelle alors que la tige (52) de la broche (20) traverse le maillon mâle. Une douille polymère (18) est ajustée sur le maillon mâle engrené dans le tige (52) de la broche (20). Ainsi, le mouvement relatif entre les maillons s'effectue à l'interface de la broche (20) à revêtement de type diamant et de la douille polymère (18).
