在滿足便用性能的前提下，應(yīng)選用裝拆方便、維護(hù)簡(jiǎn)單、成本低的聯(lián)軸器。例如剛性聯(lián)軸器不但結(jié)構(gòu)簡(jiǎn)單，而且裝拆方便，可用于低速、剛性大的傳動(dòng)軸。一般的非金屬?gòu)椥栽?lián)軸器（例如彈性套柱銷聯(lián)軸器、彈性柱銷聯(lián)軸器、梅花形彈性聯(lián)軸器等），由于具有良好的綜合能力，普遍適用于一般的中、小功率傳動(dòng)。聯(lián)軸器的可靠性和工作環(huán)境: 通常由金屬元件制成的不需潤(rùn)滑的聯(lián)軸器比較可靠；需要潤(rùn)滑的聯(lián)軸器，其性能易受潤(rùn)滑完善程度的影響，且可能污染環(huán)境。含有橡膠等非金屬元件的聯(lián)軸器對(duì)溫度，軟管流體設(shè)備，軟管流體設(shè)備、腐蝕性介質(zhì)及強(qiáng)光等比較敏感，而且容易老化，軟管流體設(shè)備。一定體積***體分子數(shù)目少，分子間作用力小，分子的無(wú)規(guī)則熱運(yùn)動(dòng)強(qiáng)烈，故易流動(dòng)。軟管流體設(shè)備</p><div
