ボン摺動材料である。(Means to solve the problem) The technical measures taken to solve the above technical problem are:
In order to prevent wear of the sliding material itself, the sliding material is filled with carbon fiber, which has the same function as silica and has high self-lubricating properties.The weight ratio is 30 to 60% carbon and 10 to 10% carbon fiber. It is a carbon sliding material consisting of 40% resin binder and 20 to 40% resin binder made of thermosetting resin such as polyimide, phenol, epoxy, furan, etc.
またカーボンファイバーは、ピッチ系、ＰＡＮ系があり

した摺動材料が効果的である。Carbon fibers include pitch-based and PAN-based types, as well as graphitic and carbonaceous types due to differences in firing temperature, and long fibers and short fibers due to differences in fiber length. It is effective, but especially for pitch-based graphite with a thickness of 1
A sliding material containing short fibers of 0 to 30 μm and length of 0.1 to 0.5 *1 is effective.

ーにより結合される。(Operation) The above technical means operates as follows. That is, in order to use carbon fiber instead of amorphous silica, carbon and carbon fiber are bonded with a resin binder.
この結果摺動面においてはカーボンファイバーが荷重を
支える作用を行い、又カーボンファイバー自体が潤滑性
を有するものである。As a result, the carbon fibers act to support the load on the sliding surfaces, and the carbon fibers themselves have lubricating properties.
アモルファスシリカなどのシリカを使用しないために摺
動面に傷が発生することはまったく無いものである。Since silica such as amorphous silica is not used, there are no scratches on the sliding surface.
