本文所介绍的三角皮带傅动的计算方法,是以苏联“机器制迭百科全书”(第二卷)和“机器制造者手册”(卷4,第2版)所推荐的计算方法作为基礎的;同时,为了简化设计与计算,一些主要的和辅助的数据均可直接由图表中查得,这样可减少设计者1/2～2/3的劳动量。三角皮带傅动所能傅遞的功率按下列公式计算:N=N_0·C·z式中:N_0——每根一定型号截面的皮带,在一定工作条件下所能傅遞的功率(马力);C——考虑到包角α和傅动工作情况对牵引能力影响的系数;z——皮带权数。N_0的数植,与小皮带输的直径及皮带的速度有关,它
The method for computing the triangular belt movement described in this paper is based on the calculation methods recommended by the Soviet Union’s “Encyclopedia of Machine Making” (Volume 2) and the “Machine Builder’s Manual” (Volume 4, Second Edition). At the same time, in order to simplify the design and calculation, some major and auxiliary data can be directly checked from the chart, which can reduce the designer’s 1/2 to 2/3 labor. The power delivered by the triangular belt can be calculated according to the following formula: N=N_0·C·z where: N_0—The power of each certain model cross-section belt, which can be delivered under certain working conditions (horsepower) ;C—The factor that takes into account the influence of the wrap angle α and the turbulent working condition on the traction ability; z—the belt weight. The number of N_0 plants depends on the diameter of the small belt and the speed of the belt.
