90L100KP液壓缸的類型與特點(一)(圖1)

?液壓缸功用:將液壓泵供給的液壓能轉換為機械能而對負載作功,實現(xiàn)直線往復運動或旋轉運動 液壓缸的類型及特點 按結構形式:活塞式,柱塞式,組合式 按作用方式:單作用式:液體或氣體只控制?缸一腔單向運動;雙作用式:液體或氣體控制缸兩腔實現(xiàn)雙向運動 活塞式液壓缸定義:在缸體內作相對往復運動的組件為活塞的液壓缸 分類: 按伸出活塞桿不同:雙桿、單桿、無桿 按固定方式不同:缸體固定、活塞桿固定 雙桿活塞液壓缸特??點: 1)兩腔面積相等; 2)壓力相同時,推力相等,流量相同時,速度相等。

即具有等推力等速度特性 推力、速度計算 v=q/A=4?q/π(D2-d2) F=(p1-p2)A?22 =π(D-d)(p1-p2)/4 工作過程 實心雙桿活塞式液壓缸—缸體固定式 空心雙桿活塞液壓缸—桿固定式 實心雙桿活塞式液壓缸—缸體固定式 進油腔回油腔運動方向占地范圍應用場合 左 右 活塞右移 三倍于L中小型設備 右 左 活塞左移 占地面積大 進油腔位置與活塞運動方向相反 空心雙桿活塞式液壓缸——桿固定式 進油腔??回油腔??運動方向?占地范圍應用場合 左 右 缸體左移 >兩倍于L,占地面積 右 左 缸體右移 小,大中型設備 進油腔位置與活塞運動方向相同 單活塞桿液壓缸 特點:1)兩腔面積不等,A1>A2 2)壓力相同時,推力不等?流量相同時,速度不等????即不具有等推力等速度特性 結論 運動行程無桿腔進油時 v1=q/A1=4q/πD =π[D p1-(D-d)p2/4 有桿腔進油時 v2=q/A2=4q/π(D-d) F2=p1A2-p2A1 =π[(D-d)p1-D?p2]/4 單活塞桿液壓缸簡單連接比較 ∵ A1>A2 ∴ v1F2 故??活塞桿伸出時,推力較大,速度較小 活塞桿縮回時,推力較小,速度較大 因而:活塞桿伸出時,適用于重載慢速 活塞桿縮回時,適用于輕載快速 往復速比:λv=v2/v1=D/D-d d=D√(λv-1)/λv 單活塞桿液壓缸簡單連接結論 活塞桿直徑越小,兩個方向速度差值越小。

固定方式和工作過程皆與雙桿活塞液壓缸相同 活塞或缸體的有效行程是運動行程的兩倍 差動連接式液壓缸 采用兩端面積差的連接形式,單桿活塞液壓缸兩腔同時進入流體 差動連接速度、推力計算 ∵ v3A1=q+v3A2 ∴ v3=q/A1-A2=4?q/πd 故??要使v2=v3,D=√ 2 d F3=p1(A1-A2)=πdp1/4 差動連接特點:在不增加流量的前提下,實現(xiàn)快速運動 單桿活塞液壓缸應用 單桿活塞液壓缸不同連接,可實現(xiàn)如下工作循?環(huán): (差動連接)(無桿腔進油)(有桿腔進油) 快進 → 工進 → 快退 v3、F3 v1、F1 v2、F2 90L075-KA-5-CD-80-R-3-S1-D-03-GBA-17-17-20 90L075KA5CD80R3S1D03GBA171720
