Title: エラストマー補強用の単撚り鋼コード
IPC: D07B1/06
Filed: 2007-11-30
Abstract: いくつかの特定の問題を解消しつつ、高い費用対効果で簡単に製造可能な、タイミングベルトなどのエラストマーベルトの補強用の鋼コード（２００）が記載されている。コード（２００）は、コアフィラメント（２０２）の周りに第１層および第２層のフィラメント（２０４，２１０，２１２）が撚り合わされ、全てのフィラメントが同一の撚り長さおよび同一の撚り方向で撚られた、単撚り鋼コードである。撚り長さ、コアフィラメント直径、および第１層のフィラメント直径（後者は、前者よりも大きいかまたは等しい）の適切な選択によって、第２層のフィラメント（２１０′）を断続的に捕捉する集合間隙が形成されている。この集合間隙は、コアフィラメント（２０２）を他のフィラメント（２０４，２１０，２１２）と同一の撚り長さおよび同一の撚り方向で変形させる望ましい効果を得るために、コアフィラメント直径の４０％〜７０％である。変形したコアフィラメント（２０２）は、その移動が抑制されることになる。加えて、コード（２００）の著しく粗い表面によって、エラストマー内での良好な機械的固定が生じ、コード（２００）に加えられた荷重は、全てのフィラメントに良好に分散される。このコードは、タイミングベルトの利用に限定されるものではなく、タイヤ、ホース、引上げベルト、駆動ベルト、補強帯片等への有効な利用が見込まれている。
