rexroth力士樂(lè)柚向柱塞泵rexroth力士樂(lè)柚向柱塞泵斜盤軸線與缸體軸線傾斜一角度,柱塞靠機(jī)械裝置或在低壓油作用下壓緊在斜盤上（圖中為彈簧）,配油盤2和斜盤4固定不轉(zhuǎn),當(dāng)原動(dòng)機(jī)通過(guò)傳動(dòng)軸使缸體轉(zhuǎn)動(dòng)時(shí),由于斜盤的作用,迫使柱塞在缸體內(nèi)作往復(fù)運(yùn)動(dòng),并通過(guò)配油盤的配油窗口進(jìn)行吸油和壓油。如圖3-23中所示回轉(zhuǎn)方向,當(dāng)缸體轉(zhuǎn)角在π～2π范圍內(nèi),柱塞向外伸出,柱塞底部缸孔的密封工作容積增大,通過(guò)配油盤的吸油窗口吸油;在0～π范圍內(nèi),柱塞被斜盤推入缸體,使缸孔容積減小,通過(guò)配油盤的壓油窗口壓油。缸體每轉(zhuǎn)一周,每個(gè)柱塞各完成吸、壓油一次,如改變斜盤傾角,就能改變柱塞行程的長(zhǎng)度,即改變液壓泵的排量,改變斜盤傾角方向,就能改變吸油和壓油的方向,即成為雙向變量泵。
rexroth力士樂(lè)軸向柱塞泵的優(yōu)缺點(diǎn)簡(jiǎn)介力士樂(lè)Rexroth柱塞泵的優(yōu)點(diǎn)
1. 參數(shù)高：額定壓力高，轉(zhuǎn)速高，力士樂(lè)油泵的驅(qū)動(dòng)功率大
2. 效率高，容積效率為95%左右，總效率為90%左右
3. 壽命長(zhǎng)
4. 變量方便，形式多
5. 單位功率的重量輕
6. 力士樂(lè)柱塞泵主要零件均受壓應(yīng)力，材料強(qiáng)度性能可得以充分利用力士樂(lè)rexroth柱塞泵的缺點(diǎn)適用于開(kāi)式回路液壓驅(qū)動(dòng)
