弹(dan)性(xing)联轴(zhou)器(qi)的(de)原理：主(zhu)要将(jiang)原动(dong)(dong)机(ji)(ji)(ji)产生的(de)转矩传递给(ji)从动(dong)(dong)机(ji)(ji)(ji)的(de)装(zhuang)置。能(neng)补偿原动(dong)(dong)机(ji)(ji)(ji)与(yu)从动(dong)(dong)机(ji)(ji)(ji)之(zhi)间由于制(zhi)造(zao)误差(cha)、安装(zhuang)误差(cha)、承载后的(de)变形以及温度变化(hua)所引起(qi)的(de)轴(zhou)向(xiang)(xiang)、径向(xiang)(xiang)和角向(xiang)(xiang)偏差(cha)。利(li)用(yong)膜片（或(huo)弹(dan)性(xing)体）的(de)弹(dan)性(xing)作用(yong)，承担联结主(zhu)、从动(dong)(dong)机(ji)(ji)(ji)传递扭矩；补偿两轴(zhou)线的(de)三向(xiang)(xiang)位移(yi)以及消(xiao)振(zhen)、隔振(zhen)作用(yong)。其中无(wu)齿隙(xi)弹(dan)性(xing)联轴(zhou)器(qi)为(wei)：具有结构尺寸小、重量(liang)轻(qing)、传递扭矩大、之(zhi)特点。能(neng)地传动(dong)(dong)机(ji)(ji)(ji)械的(de)运动(dong)(dong)质量(liang)和稳定性(xing)。

弹(dan)(dan)性(xing)(xing)活销联(lian)(lian)(lian)轴(zhou)(zhou)器(qi)(qi)(qi)是我由我国研制的(de)新(xin)型(xing)联(lian)(lian)(lian)轴(zhou)(zhou)器(qi)(qi)(qi)，它集中现有(you)标准弹(dan)(dan)性(xing)(xing)联(lian)(lian)(lian)轴(zhou)(zhou)器(qi)(qi)(qi)不同结构的(de)优点，例如句(ju)有(you)梅花形弹(dan)(dan)性(xing)(xing)联(lian)(lian)(lian)轴(zhou)(zhou)器(qi)(qi)(qi)的(de)优点：弹(dan)(dan)性(xing)(xing)元(yuan)件受挤(ji)压，结构简(jian)单，性(xing)(xing)高。克服了梅花形弹(dan)(dan)性(xing)(xing)联(lian)(lian)(lian)轴(zhou)(zhou)器(qi)(qi)(qi)的(de)缺点：换(huan)(huan)弹(dan)(dan)性(xing)(xing)元(yuan)件时移(yi)(yi)动(dong)半联(lian)(lian)(lian)轴(zhou)(zhou)器(qi)(qi)(qi)，双法兰梅花形弹(dan)(dan)性(xing)(xing)联(lian)(lian)(lian)轴(zhou)(zhou)器(qi)(qi)(qi)虽可(ke)不用(yong)移(yi)(yi)动(dong)半联(lian)(lian)(lian)轴(zhou)(zhou)器(qi)(qi)(qi)也能换(huan)(huan)弹(dan)(dan)性(xing)(xing)元(yuan)件，但(dan)结构复杂，成本高，增加了质量和转(zhuan)动(dong)惯量，应用(yong)范围受到限制。传递相同转(zhuan)矩时径向尺寸(cun)比(bi)GB4323弹(dan)(dan)性(xing)(xing)套柱(zhu)销联(lian)(lian)(lian)轴(zhou)(zhou)器(qi)(qi)(qi)小得(de)多，质量轻，转(zhuan)动(dong)惯量小。
