    • A timing belt having an outer section defined by cogged ribs defining a preselected controlled coefficient of friction obtained by providing controlled size grooves extending transversely through the ribs. The ratio of the effective side area of the grooves to the side area of the cogs defined in the ribs by the grooves, in the illustrated embodiment, is in the range of approximately 1/2 to 21/2 where the coefficient of the rib material is approximately 0.35. The cogs are raw edged and provided with a cover fabric. The provision of the cogged ribs permits the belt to be used as a double timing belt as well as providing improved functioning with backside rib pulleys. The effective coefficient of friction obtained by reducing the side area of the ribs as a result of the provision of the grooves is preferably in the range of 0.15 to approximately 0.90. The total area of all of the side faces of the cogs and effective side areas of the grooves is approximately equal to the height of the outer section defined by the cogs and grooves multiplied by the length of the belt.
    • 一个同步皮带,具有由齿槽肋限定的外部部分,所述外部部分限定了通过横向延伸穿过所述肋部延伸的受控尺寸的凹槽而获得的预选的受控摩擦系数。 在所示实施例中,通过槽限定在肋中的槽的有效侧面积与齿的侧面积的比率在大约1/2至21/2的范围内,其中肋材料的系数 约0.35。 这些齿是原始边缘,并提供有一个覆盖织物。 齿槽肋的设置允许带被用作双重同步带,并且提供改进的功能与后侧肋皮带轮。 通过减少作为槽的结果的肋的侧面面积获得的有效摩擦系数优选在0.15至约0.90的范围内。 齿槽的所有侧面和凹槽的有效侧面的总面积大致等于由齿槽和凹槽限定的外部部分的高度乘以皮带的长度。

    • An antistatic driving belt having a durable destaticizing function and long surface life. A cushion rubber layer is disposed between a tension rubber layer and a compression rubber layer, and tension members are buried in the cushion rubber layer. A layer of conductive rubber blended with conductive material and having a high abrasion resistance is arranged on the underside of the cushion rubber layer. The ends of the layer of conductive rubber are exposed on both sides of the belt. Preferably, the conductive rubber layer is formed of rubber containing 5 to 50 parts by weight of conductive material to 100 parts by weight of rubber. The conductive rubber layer should be 0.1 mm or thicker, and should have a thickness less than half the total thickness of the compression layer.
    • 一种抗静电驱动带,具有持久的去电功能和较长的表面寿命。 缓冲橡胶层设置在拉伸橡胶层和压缩橡胶层之间,拉伸构件埋设在缓冲橡胶层中。 在缓冲橡胶层的下侧设置有与导电材料混合并具有高耐磨性的导电橡胶层。 导电橡胶层的端部暴露在带的两侧。 优选地,导电橡胶层由含有5至50重量份导电材料的橡胶至100重量份的橡胶形成。 导电橡胶层应为0.1mm或更厚,并且应具有小于压缩层总厚度的一半的厚度。
