力士樂柱塞泵特征:柱塞軸線平行或傾斜于缸體的軸線1. REXROTH柱塞泵軸向柱塞泵的工作原理
1) 力士樂斜盤式軸向柱塞泵 組成:配油盤、柱塞、缸體、傾斜盤等 工作原理:V密形成——柱塞和缸體配合而成 右半周,V密增大,吸油 V密變化,缸體逆轉(zhuǎn)< 左半周,V密減小,壓油 吸壓油口隔開—配油盤上的封油區(qū)及缸體底部的通油孔2) 力士樂斜軸式軸向柱塞泵 特點(diǎn):傳動(dòng)軸軸線與缸體軸線傾斜一γ角。 組成: 工作原理:V密形成——同上 右半周,吸油 V密變化——傳動(dòng)軸逆轉(zhuǎn)< 左半周,壓油 吸壓油口隔開——同上2.REXROTH柱塞泵軸向柱塞泵的排量和流量
1) 排量 若柱塞數(shù)為z,柱塞直徑為d,柱塞孔的分布圓直徑為D, 斜盤傾角為γ, 則柱塞的行程為:h=Dtanγ,故缸體轉(zhuǎn)一轉(zhuǎn), 泵的排量為: V=Zhπd /4= π d2 ZD(tanγ)/4 2) 流量 理論流量: qT = Vn = πd2D(tanγ)z/4 實(shí)際流量: q = qTηpv =πd2D(tanγ)zηpv/4 結(jié)論:
(1) qT = f(幾何參數(shù)、 n、γ)
(2) n = c 大小變化,流量大小變化 γ< 方向變化,輸油方向變化 變量原理: ∵ γ= 0 q = 0 大小變化,流量大小變化 γ< 方向變化,輸油方向變化 ∴ 軸向柱塞泵可作為雙向變量泵 瞬時(shí)流量: 柱塞的軸向位移: s = a’b’=oa’-ob’ = Dtanγ/2 – Dcosωttanγ/2 = D(1-cosωt)tanγ/2 力士樂柱塞泵的瞬時(shí)移動(dòng)速度: u = ds/dt = Dωtanγsinωt/2 單個(gè)力士樂柱塞泵的瞬時(shí)流量為: q‘=πd2u/4=πd2Dωtanγsinωt/8 ∵ 單個(gè)柱塞的瞬時(shí)流量按正弓玄規(guī)律變化 ∴ 整個(gè)泵的瞬時(shí)流量也按正弓玄規(guī)律變化 故 瞬時(shí)流量是脈動(dòng)的,其脈動(dòng)情況用脈動(dòng)率δ來表示, 一般: z = 奇數(shù),δ小 z = 偶數(shù),δ大 常取z = 7 或z = 93. REXROTH柱塞泵軸向柱塞泵的結(jié)構(gòu)
(1) 斜盤式軸向柱塞泵
1) 非通軸式力士樂軸向柱塞泵 CY14——1力士樂軸向柱塞泵主體部分: 使泵具有自吸性能 中心彈簧< 提高容積效率 中心彈簧 缸體端面間隙的自動(dòng)補(bǔ)償< 缸體底部通油孔p 除中心彈簧使缸體緊壓配流盤外,柱塞孔底部的液壓力也使缸體緊貼配 流盤,補(bǔ)償端面間隙,提高了容積效率 A 滑靴和斜盤 球形頭部——和斜盤接觸為點(diǎn)接觸,接觸應(yīng)力大,易磨損。 柱塞頭部結(jié)構(gòu)< 滑靴結(jié)構(gòu)——和斜盤接觸為面接觸,大大降低了磨損。 B 柱塞和缸體② CY14——1力士樂軸向柱塞泵變量機(jī)構(gòu) 手動(dòng)*—轉(zhuǎn)動(dòng)手輪控制斜盤,改變傾角即可 變量機(jī)構(gòu)< 自動(dòng) 2) 通軸式軸向柱塞泵 非通軸結(jié)構(gòu)(半軸):受力狀態(tài)不佳,壽命短,噪聲大,成本高。 區(qū)別< 通軸結(jié)構(gòu):主軸采用兩端支承,受力情況變好;在泵的外端安裝 一小型輔助泵,簡化油路。
