液力耦合器是一種液力傳動(dòng)裝置，一般由泵輪和渦輪組成，它們統(tǒng)稱工作輪，放在密封殼體中。殼中充入一定量的工作液體，當(dāng)泵輪在原動(dòng)機(jī)帶動(dòng)下旋轉(zhuǎn)時(shí)，處于其中的液體受葉片推動(dòng)而旋轉(zhuǎn)，在離心力作用下沿著泵輪外環(huán)進(jìn)入渦輪時(shí)，就在同一轉(zhuǎn)向上給渦輪葉片以推力，使其帶動(dòng)生產(chǎn)機(jī)械運(yùn)轉(zhuǎn)。液力耦合器的動(dòng)力轉(zhuǎn)輸能力與殼內(nèi)相對(duì)充液量的大小是一致的。在工作過(guò)程中，改變充液率就可以改變耦合器的渦輪轉(zhuǎn)速，做到無(wú)級(jí)調(diào)速。本方法適用于風(fēng)機(jī)、水泵的調(diào)速。
其特點(diǎn)為：1、功率適應(yīng)范圍大，可滿足從幾十千瓦至數(shù)千千瓦不同功率的需要；2、結(jié)構(gòu)簡(jiǎn)單，工作可靠，使用及維修方便，且造價(jià)低；3、尺寸小，能容大；4、控制調(diào)節(jié)方便，容易實(shí)現(xiàn)自動(dòng)控制。
