一、前言目前在连续动作式运输机械中,生产率最大,效率最高的要算是皮带运输机了,皮带运输机除了具有上述的优点外,还有噪音很小,运转平稳,摩擦损失小等一系列的优点,因此在煤矿工业中无论是在露天还是在地下矿内都获得非常广泛的应用。同时由于采矿工业规模的扩大,采矿机械生产率的提高,各国煤矿工业部门中都在不断出现高生产率的巨大的新型皮带运输机。下面仅就皮带运输机传动理论中的两个问题探讨一下。 I. Preface At present, in the continuous operation type transport machinery, the belt conveyor has the highest productivity and the highest efficiency. Besides the advantages mentioned above, the belt conveyor has a series of advantages such as low noise, stable operation and small friction loss , So it has gained a very wide range of applications in the coal mining industry both in the open air and in underground mines. At the same time, due to the expansion of the scale of the mining industry and the improvement of the mining machinery productivity, huge new belt conveyors with high productivity have been constantly emerging in the coal mining industry in various countries. The following only on the belt conveyor transmission theory of two questions to explore.
