2.由驅(qū)動機械（如電機）動力 [KW,HP] 及聯(lián)軸器使用回轉(zhuǎn)數(shù) [N] 求得聯(lián)軸器承受的轉(zhuǎn)矩 [TA] TA(Kg.m)=973.5×KW/N(rpm)=716.2×HP/N(rpm)或 TA(N·m)=9550×KW/N(r/min) 3.由被正系數(shù)表中查得負(fù)載條件系數(shù) K1 ，運轉(zhuǎn)時間系數(shù) K2 ，起動停止頻度系數(shù) K3 ，周圍環(huán)境溫度系數(shù)K4 ，求得補正扭力 [TD] 。 TD=TA · K1 · K2 · K3 · K4 4.選用聯(lián)軸器的常用轉(zhuǎn)矩必須大于被正轉(zhuǎn)矩。 5.聯(lián)軸器所能承受的較大扭力必須大于原動側(cè)及被動側(cè)雙方所產(chǎn)生的較大扭力。 6.確定孔徑范圍是否適用。 7.除了以上的選定步驟外，對于振動頻率亦須檢討。即轉(zhuǎn)矩變動的頻率與軸的固有振動數(shù)避免造成共振的現(xiàn)象產(chǎn)生。流體</p></p><br /><p>文章來源地址:
