Abstract
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. The shaft of each connector pin is coated with a diamond-like coating having high hardness, low friction and low wear characteristics. Opposite ends of the connector pins are connected to the female link while the shaft of the connector pin passes through the male link. A polymeric bushing is fitted to the male link in engagement with the shaft of the connector pin. Accordingly, relative movement between the links occurs at the interface of the DLC connector pin and the polymeric bushing.
Claims16
A chain for a roller chain conveyor comprising:
- a male link;
- a female link mounted to said male link by a connector member, said connector member including a shaft, said shaft being coated with a diamond-like coating;
- a roller rotatably mounted to said connector member with said male link and said female link;
- and
- a polymeric bushing fitted within said roller, said bushing surrounding said shaft, such that said coating directly interfaces with said bushing.
A roller chain for a roller chain conveyor comprising:
- a male link having a surface defining at least one connector opening, said surface being coated with a diamond-like coating;
- a female link interconnected with said male link by a connector member;
- a polymeric bushing fitted about said connector member and extending into said connector opening, such that said coating directly interfaces with said bushing;
- and
- a roller rotatably mounted to said connector member.
A roller chain for a roller chain conveyor comprising:
- a male link having a pair of spaced apart plates;
- a female link having a pair of spaced apart plates;
- a connector member interconnecting said female link and said male link, at least a portion of said connector member having a diamond-like coating;
- a roller rotatably mounted over said connector member;
- and
- a polymeric bushing mounted over said connector member within said roller, such that said roller directly interfaces with said bushing.
