膠带的选择,应根据它能传动多大的马力才作适当的决定。关于马力的计算,一般就将主动机械的额定马力乘上一“使用因数”,该使用因数即表示每当起动或加速时所引起膠带过载之影响。至于被动机械方面,当然在决定采用主动机械时已有适当考虑,故被动机械方面的影响可少加考虑。上述方法已早为一般所采用。随着主动机械种类之不同,及被动机械种类与用途之不同,即有各种各样不同程度之过载情形出现。所示为各种不同过载情形下之“使用 The choice of tape should be based on how much horsepower it can drive for proper decisions. For horsepower calculations, the rated horsepower of the prime mover is generally multiplied by a “use factor” which indicates the effect of the tape overload each time it is started or accelerated. As for passive machinery, of course, proper consideration has been given when deciding to adopt active machinery, so the influence of passive machinery can be considered with little consideration. The above method has long been generally used. With the different types of active machinery and the different types and uses of passive machinery, there are various levels of overloading situations. Shown for a variety of different overload situations "use
