CHAIN BEARING, CHAIN PIN, AND CHAIN |
| 摘要 |
At least one member composing a chain bearing, e.g., a pin, includes a surface layer composed of vanadium carbonitride (VCN) coating on a surface of a base material of the one member. An oxide (VO) film having a predetermined thickness is also formed on a surface of the surface layer such that the oxide film is interposed between the surface layer and another member, e.g., a pin hole, composing the bearing. The VO film is suppressed from being formed excessively by the VCN coating even under a severe environment. |

1. A chain bearing comprising: two members slidably fitting with each other and flexibly connecting links, at least one member composing the chain bearing including:
a surface layer composed of a vanadium carbonitride coating formed on a surface of a base material of the one member and containing vanadium, carbon and nitrogen; and an oxide film formed on a surface of the surface layer such that the oxide film is interposed between the surface layer and another member among the two members, the oxide film being formed at a predetermined thickness and being softer than the vanadium carbonitride coating. |
