容積效率,，對(duì)液壓泵是指其實(shí)際流量與理論流量的比值,。對(duì)液壓馬達(dá)是指其理論流量與實(shí)際流量的比值。
機(jī)械效率,，對(duì)液壓泵是指其理論轉(zhuǎn)矩與實(shí)際輸入轉(zhuǎn)矩的比值,。對(duì)液壓馬達(dá)其實(shí)際輸出的轉(zhuǎn)矩為理論轉(zhuǎn)矩克服摩擦力后的轉(zhuǎn)矩，因此其機(jī)械效率為實(shí)際輸出轉(zhuǎn)矩與理論轉(zhuǎn)矩的比值,。
總效率是指泵（或馬達(dá)）的輸出功率與輸入功率的比值,。總效率等于容積效率與機(jī)械效率的乘積,。卸荷片和密封環(huán)必須裝進(jìn)油腔,，兩軸套才能保持平衡。導(dǎo)向鋼絲彈力應(yīng)能同時(shí)將上,、下軸套朝從動(dòng)齒輪旋轉(zhuǎn)方向扭轉(zhuǎn)一微小角度,，使主、從動(dòng)齒輪兩個(gè)軸套加工平面緊密貼合
