传动链条的种类 △滚子链（套筒滚子链）--结构较简单、重量轻、价格较便宜，已标准化，应用最广 △套筒链--结构与滚子链相同，只是没有滚子结构简单，重量轻，价格比滚子链低，但寿命较短，常用于低速 △齿形链--与滚子链相比，工作平稳、噪音较小、承受冲击载荷能力较高，但结构复杂、较重、价格较贵常用于高速或运动精度要求较高的传动4) 链传动用短节精密滚子链和套筒链链轮公差（GB1244-85）A系列滚子链的基本参数及主要尺寸（GB 1243.1-83）基本参数 其它有关基本参数 链号节距p排距Pt滚子外径d1max内链节内宽b1min销轴直径d2max套内径d3min内链板外宽b2max外链板内宽b3max销轴长度单排b4max双排b5max三排b6maxmm08A10A12A16A20A24A28A32A40A48A12.715.87519.0525.431.7538.144.4550.863.576.214.3818.1122.7829.2935.7645.4448.8758.5571.5587.837.9510.1611.9115.8819.0522.2325.428.5839.6847.637.859.412.5715.7518.925.2225.2231.5537.8547.353.965.085.947.929.5311.112.714.2719.8423.84.015.135.997.979.5811.1512.7514.3219.8923.8511.1813.8417.7522.6127.6435.4637.1945.2154.8967.8911.2313.8917.8122.6627.5135.5137.2445.2654.9467.8717.821.826.933.541.150.854.965.580.395.532.339.949.862.77796.3103.6124.2151.9183.446.757.972.691.7113141.7152.4182.9223.5271.3注：标记示例：A系列、节距25.4mm、双排、64节的滚子链，标记为：16A--2×64（GB1243-83）。
