Abstract

一种多肋动力传送带，在其压缩部分上有横向凹 槽，这些凹槽与传送带的纵向不相垂直，因而在紧邻 的纵向肋上的横向凹槽在纵向上相互偏离了一个距 离，其值为这些槽的纵向间距的10％到50％。

Description

本发明涉及使操作噪声减至最小的多肋动力传送带。
已知有很多具有各种凹槽结构的动力传送带。美国专利4，011，766号公开了一种由多个带元件组成的传送带，这些带元件用一个系紧带相连，每个带元件都有垂直于带侧面的多个横向凹槽。相邻带元件上的凹槽交错设置，并可选择有不同的间隔，以消除铰链点，使噪声无规则化，这并不是企图使各个带元件所产生的噪声减至最小。对于由组装前先形成凹槽的各个带元件构成的传送带，这种想法是可行的，但对于要作成单个部件和装到机器上的多肋传送带，这种想法尚不可行，而将多肋传送带作成单个部件和装到机器上是现在制造大多数汽车用和工业用多肋传送带的现行方法。
美国专利4，034，651号公开了一种具有很多斜凹槽的单一V形传送带。虽然这种传送带减少了每个槽所产生的噪声，但它并不能使噪声消除，这种噪声可通过使相同频率的多个声源互相异相操作而消除。此外，此专利未公开多肋传送带。
美国专利5，055，090号公开了一种有槽的多肋传送带，这种带有无规则的槽间隔和（或）深度。虽然这可以使噪声散布在较宽的频率范围，但这并不能明显地减小总的噪声。此外，这种方法的缺点还在于螺旋形凹槽的设计，因为有些凹槽比为获得最大的挠曲寿命所需的最佳凹槽的尺寸长或浅。长或浅的凹槽有较高的应力集中，是首先产生破裂的区域。最后，这些槽垂直于弯曲方向，产生很多铰链点。由此易使单个肋的裂纹扩展到整个带宽。
美国专利5，209，705号公开了单件的同步驱动传送带，此种带上有至少两排相邻的齿，这两排齿与带的纵向构成互相对称的斜角。此外，相邻排上的齿的中心线相互偏离一个距离，此距离可大到这些齿间距的10%到90%。
美国专利5，211，608号公开了一种强制驱动牙轮传送带，在其齿内切有多个螺旋形凹槽，以便允许空气从各个方向逃逸出去。
这里公开的本发明对现有技术作了改进，通过控制各个肋的噪声源之间的相位角和设置不垂直于带的纵向但与其成一个角度的多个横向凹槽而减少每个肋所产生的噪声，使噪声消除达到最佳化。本发明还采用恒定的横向凹槽深度使每个凹槽上的应力平均，消除了任何铰链点。
按照本发明的实践，提供一种多肋动力传送带，它包括一个拉伸部分，一个负载部分和一个压缩部分。压缩部分有多个纵向肋和很多平行的横向凹槽，这些凹槽的纵向间距为P。这些横向凹槽的设置方向与带的纵向不相垂直，其夹角为α，从而在相邻纵向肋上的任何横向凹槽彼此在纵向偏离了一个距离，其值为槽间距P的10%到50%。
图1是本发明传送带的一部分的底面图。
图2是沿图1中2-2线取的带的放大断面图。
图3是沿图1中线3-3线的带的放大断面图。
标记为10的多肋动力传送带有一拉伸部分12，一负载部分14和一压缩部分16。所述的压缩部分有多个纵向肋18和很多平行的横向凹槽20，这些凹槽在纵向的间隔为P。这些横向凹槽20定位于不与纵向L垂直，而是与其成α夹角，因而在相邻纵向肋18上的横向凹槽20相互间具有纵向位移X，其值为槽间距P的10%到50%。
横向凹槽20的斜角α为20°-85°，主要取决于间距P，槽的位移X和纵向沟槽之间的间距d及肋的数目。附图所示的肋数为6，但应理解一条多肋动力传送带可以包括3到30或更多的肋。附图3所示凹槽为U形，然而应理解它们也可呈V形或圆底的V形或任何其它适宜的形状。槽向凹槽的深度C和纵向沟槽的深度r可以相同也可不同。纵向沟槽的深度r一般大于横向凹槽的深度C，但不能深到切入纵向加强绳22。
在附图中示明的本发明的带为弹性体。这些弹性体可以是那些已知适于用作这种带子的任何一种材料，例如氯丁橡胶，聚氨基甲酸乙酯，NBR，IIR，IR，SBR，CSM，EPDM，其它的热固性材料，热塑性弹性体和其它聚合物合金。
这种带的负载部分14可由任何适宜的材料，用在本技术领域中任何适宜的技术制作。负载部分14最好由螺旋形缠绕的承载绳22组成，所缠绕的分开的各圈以大体相同的间隔垮过带体。制作这些绳的材料可以是玻璃纤维，碳纤维，钢丝，聚酯丝，高弹性人造丝或芳族聚酰胺丝。
制造本发明传送带的优选的方法是反向放置在适宜直径的刚性型芯上制作。首先将一层拉伸料放置在型芯上，接着螺旋形缠绕强化绳22。然后将一层弹性料置于强化绳22上。通过一种挠性的膜板在产品固化时模制出斜的凹槽20，此膜板上有与所述凹槽相对的螺旋形图案，将此膜板放在弹性料上，而后用蒸汽压力，空气压力或其它方法将膜板压在制品上。在固化工艺之后，再通过机加工，研磨等常规方法在产品上形成纵向沟槽。
