一、窄V带与普通V带的比较窄V带是在普通V带的基础上发展形成的一种新型胶带,由于它的传动特点大大优于普通V带,故在新设计设备上有取代普通V带的趋势,是V带传动中最有前途的型式之一,且采用窄V带传动是现代设备的重要标志之一.其与普通V带相比.传动性能方面主要有如下特点. 1.传递功率高。在同样的工作条件下,由于窄V带结构合理,它所传递的功率值比普通V带高0.2～1.5倍.如在100转/分时,E型普通V带单根功率容量为51.5马力,8V型窄V带为85.6马力,提高66.2%;以大庆Ⅰ-130型钻机为例.采用E型传动带,传动轴输入功率为768马力,带轮直径为630毫米,传动比为1,转速
First, the narrow V-belt V-belt with a relatively narrow V-belt V-belt is based on the common development of the formation of a new type of tape, because of its transmission features much better than ordinary V-belt, it replaced the new design equipment The trend of ordinary V-belt is one of the most promising V-belt drive models, and the use of narrow V-belt drive is an important symbol of modern equipment, which compared with the normal V-band. Transmission performance mainly has the following characteristics. High transmission power Under the same operating conditions, the narrow V-belt structure has a reasonable power transmission value of 0.2 to 1.5 times higher than that of the ordinary V-belt, for example, at 100 rpm, the E-type ordinary V-belt has a single power capacity of 51.5 hp , 8V narrow V belt is 85.6 horsepower, increased by 66.2%; Take Daqing Ⅰ-130 type drilling machine as an example.Use E-shaped transmission belt, the transmission shaft input power of 768 horsepower, the pulley diameter of 630 mm, the transmission ratio of 1, speed
