Description
の歯部、及び、心線が埋設された背部を含む、ゴムを基材としたベルト本体と、前記複数
の歯部の表面を被覆する歯布とを有する歯付ベルトであって、
前記歯布が、経糸と少なくとも2種類の緯糸とが織成された多重織構造を有し、前記経
糸がナイロン繊維であり、前記2種類の緯糸のうちの前記歯布の表面側に位置する緯糸が
フッ素系繊維であり、前記フッ素系繊維の周囲に、前記ベルト本体の加硫温度で軟化又は
融解する、低融点繊維が配され、前記低融点繊維が、前記歯布を構成する繊維間に介在していることを特徴とするものである。
次に、2軸高負荷走行試験を用いた耐久試験を行って、本発明の歯付ベルトの技術的効果を検証した。
試験機:2軸高負荷走行試験機
評価ベルトサイズ:130H14M20(ベルト歯数:130歯、歯型:H14M、ベルト幅:20mm)
駆動プーリ歯数:33歯
従動プーリ歯数:61歯
設定張力:550N
回転数:1200rpm
負荷:従動プーリに対して626Nm(走行条件1)、554Nm(走行条件2)、480Nm(走行条件3)の何れか
ベルト1mm幅当たりの心線断面積(mm2/ベルト1mm)
=(ベルト幅(mm)/心線ピッチ(mm))×1本当たりの心線断面積(mm2/本)÷ベルト幅(mm)
=1本当たりの心線断面積(mm2/本)/心線ピッチ(mm2)
心線占有率(%)
=心線の有効本数n(本)×心線径Dc(mm)÷ベルト幅B(mm)×100
尚、心線の有効本数nとは、ベルトの幅方向に並ぶ心線の数であるが、表7、表8では、ベルト幅Bを心線ピッチで除して、小数点以下を切り捨てた値としている。
表7、表8に示されているように、ベルト1mm当たりの心線断面積が小さい(<1.10)、比較例のベルトTG−1は、最も負荷の低い走行条件3でも、30時間程度でベルト故障が生じ、耐久性がかなり低い。一方、ベルトTG−1よりも心線断面積が大きく、また、心線の撚係数が1.5≦K≦2.5(表2参照)の範囲内にあるベルトTG−2〜5では、ベルトTG−1と比べて、同じ走行条件3で4倍以上の寿命が得られており、耐久性が向上していることがわかる。

Claims (2)
- ベルト長手方向に沿って所定間隔で配置された複数の歯部、及び、心線が埋設された背部を含む、ゴムを基材としたベルト本体と、前記複数の歯部の表面を被覆する歯布とを有する歯付ベルトであって、
前記歯布が、経糸と少なくとも2種類の緯糸とが織成された多重織構造を有し、
前記経糸がナイロン繊維であり、前記2種類の緯糸のうちの前記歯布の表面側に位置する緯糸がフッ素系繊維であり、
前記フッ素系繊維の周囲に、前記ベルト本体の加硫温度で軟化又は融解する、低融点繊維が配され、前記低融点繊維が、前記歯布を構成する繊維間に介在していることを特徴とするゴム製歯付ベルト。 - 前記低融点繊維が、少なくともポリアミド系繊維、ポリエステル系繊維、又は、オレフィン系繊維から選ばれたものであることを特徴とする請求項1に記載のゴム製歯付ベルト。
