Rexroth徑向柱塞馬達(dá)軸與缸體相連接一起旋轉(zhuǎn)。當(dāng)壓力油經(jīng)配油盤的窗口進(jìn)入缸體的柱塞孔時(shí),柱塞在壓力油作用下外伸,緊貼斜盤斜盤對(duì)柱塞產(chǎn)生一個(gè)法向反力p,此力可分解為軸向分力及和垂直分力Q。Q與柱塞上液壓力相平衡,而Q則使柱塞對(duì)缸體中心產(chǎn)生一個(gè)轉(zhuǎn)矩,帶動(dòng)馬達(dá)軸逆時(shí)針方向旋轉(zhuǎn)。軸向柱塞馬達(dá)產(chǎn)生的瞬時(shí)轉(zhuǎn)矩是脈動(dòng)的。若改變馬達(dá)壓力油輸入方向,則馬達(dá)軸按順時(shí)針方向旋轉(zhuǎn)。斜盤傾角a的改變、即排量的變化,不僅影響馬達(dá)的轉(zhuǎn)矩,而且影響它的轉(zhuǎn)速和轉(zhuǎn)向。斜盤傾角越大,產(chǎn)生轉(zhuǎn)矩越大,轉(zhuǎn)速越低。
Rexroth徑向柱塞馬達(dá)的工作原理圖。壓縮空氣由A孔輸入時(shí)分為兩路:一路經(jīng)定子兩端密封蓋的槽進(jìn)人葉片底部(圖中未表示),將葉片推出,葉片就是靠此氣壓推力及轉(zhuǎn)子轉(zhuǎn)動(dòng)后離心力的綜合作用而緊密地貼緊在定子內(nèi)壁上。壓縮空氣另一路經(jīng)且孔進(jìn)入相應(yīng)的密封工作空間而作用在兩個(gè)葉片上,由于兩葉片伸出長(zhǎng)度不等,就產(chǎn)生了轉(zhuǎn)矩差,使葉片與轉(zhuǎn)子按逆時(shí)針方向旋轉(zhuǎn);作功后的氣體由定子上的孔C排出,剩余殘氣經(jīng)孔占排出。若改變壓縮空氣輸入方向(即壓縮空氣自B孔進(jìn)入,A孔和C孔排出),則可改變轉(zhuǎn)子的轉(zhuǎn)向。 圖b是徑向活塞式氣動(dòng)馬達(dá)的工作原理圖。壓縮空氣經(jīng)進(jìn)氣口進(jìn)入分配閥(又稱配氣閥)后再進(jìn)入氣缸,推動(dòng)活塞及連桿組件運(yùn)動(dòng),再使曲軸旋轉(zhuǎn)。在曲軸旋轉(zhuǎn)的同時(shí),帶動(dòng)固定在曲軸上的分配閥同步轉(zhuǎn)動(dòng),使壓縮空氣隨著分配閥角度位置的改變而進(jìn)入不同的缸內(nèi),依次推動(dòng)各個(gè)活塞運(yùn)動(dòng),并由各活塞及連桿帶動(dòng)曲軸連續(xù)運(yùn)轉(zhuǎn),與此同時(shí),與進(jìn)氣缸相對(duì)應(yīng)的氣缸則處于排氣狀態(tài)。
