    • A power transmission belt having a tension section and a compression section, with at least a portion of one of the tension and compression sections being formed from rubber of a first color. A rubber coated canvas covers at least a part of at least one of the tension and compression sections including the portion of the one of the tension and compression sections having the first color. The rubber in the rubber coated canvas has a second color that is different than the first color. A rubber layer having a third color is interposed between the portion of the one of the tension and compression sections and the rubber coated canvas. The third color is substantially the same as the second color.
    • 一种动力传递带,其具有张紧部和压缩部,所述张力压缩部中的至少一部分由第一颜色的橡胶形成。 橡胶涂覆的帆布覆盖至少一个张力和压缩部分的至少一部分,包括具有第一颜色的张力和压缩部分中的一个的部分。 橡胶涂层帆布中的橡胶具有与第一种颜色不同的第二种颜色。 具有第三颜色的橡胶层插入在一个张力和压缩部分的部分与橡胶涂覆的帆布之间。 第三种颜色基本上与第二种颜色相同。

    • 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。
