一、绪言使用挠性传动,在我国已有悠久历史。根据刘仙洲教授的研究,远在三千年以前,我们的祖先在纺织机上就已经应用到绳索传动;到十四世纪初页(元朝初年),在棉纺机上已经出现了利用绳带作为交叉传动的增速装置。在西欧,从十六世纪初页才开始将绳索传动用于手钻及其他用马拉的传动装置中。正式的平皮带传动,大约是在十九世纪初页才出现;到1830年,传动所用的皮革带,其宽度已达300毫米。三角皮带则是本世纪20年代才开始出现的。早期的皮带传动,传递的功率很小,允许的速度也很低。
I. INTRODUCTION The use of flexible transmission has a long history in our country. According to Professor Liu Xianzhou’s study, three thousand years ago, our ancestors had been applied to ropes on textile machines. By the beginning of the fourteenth century (in the first year of the Yuan Dynasty), the use of ropes as a cross-transmission had increased Speed device. In Western Europe, rope drives were used in hand drills and other horse-drawn gears from the beginning of the sixteenth century. The official flat belt drive appeared about at the beginning of the nineteenth century; by 1830, the leather belt used for transmission had reached a width of 300 mm. V-belt is only 20 century began to appear. Early belt drive, transmission of power is small, the allowable speed is very low.
