窄V带传动具有传递功率大、工作寿命长、运转速度高及占用体积小等优点,因此在机械工业中的应用已日趋广泛。GB/T13575.2带传动—窄V带传动国家标准(以下简称国标),推荐了一整套诸如工况系数表、选型图、基本额定功率和传动比功率增量表,长度修正系数表,包角修正系数表等设计资料,为工程技术人员设计窄V带传动提供了可靠的设计依据。随着电脑应用的飞速发展,带传动CAD也很自然地进入机械设计领域。如由CAD来确定单根窄V带传递的额定功率P,则首先要将3种型号(9N、15N、25N)单根窄V带基本额定功率PI值、传动比功率增量否PI值、长度修正系数K_1值、包角修正系数K_α值共计4169个数据,存入计算机内,再用二元三点插值法来查取
Narrow V-belt transmission has the advantages of large transmission power, long working life, high running speed and small occupying volume. Therefore, it has been widely used in the machinery industry. GB / T13575.2 with transmission - Narrow V-belt drive the national standard (hereinafter referred to as the national standard), recommended a set of such as working condition coefficient table, selection diagram, the basic power rating and transmission power increment table, length correction coefficient table, Wrap angle correction coefficient table and other design information for engineering and technical personnel to design a narrow V-belt drive provides a reliable design basis. With the rapid development of computer applications, belt drive CAD is also naturally into the field of mechanical design. For example, if the rated power P delivered by a single narrow V-belt is determined by CAD, the basic power ratings of the single narrow V-belt of three models (9N, 15N, 25N), the PI power increment, Length correction coefficient K_1 value, angle correction coefficient K_α value a total of 4169 data, stored in the computer, and then use the binary three-point interpolation to access
