滚子链是一种用于传送机械动力链条,广泛应用于家庭、工业和农业机械,其中包括输送机、绘图机、印刷机、汽车、摩托车、以及自行车。它由一系列短圆柱滚子链接在一起,由一个称为链轮的齿轮驱动。这是一个简单,可靠,高效的动力传递装置。 [1]
虽然汉斯·瑞诺德被认为于1880年发明了滚子链,16世纪达芬奇的草图显示一个链条以及滚子轴承。[2]

- ^ In the 16th century, Leonardo da Vinci made sketches of what appears to be the first steel chain. These chains were probably designed to transmit pulling, not wrapping, power because they consist only of plates and pins and have metal fittings. However, da Vinci's sketch does show a roller bearing.Tsubakimoto Chain Co. (编). The Complete Guide to Chain. Kogyo Chosaki Publishing Co., Ltd. 1997: 240 [2006-05-17]. ISBN 0-9658932-0-0. p. 211.
