?柱塞式液壓缸定義:在缸體內(nèi)做相對往復(fù)運(yùn)動(dòng)的組件是柱塞的液壓缸 柱塞式液壓缸結(jié)構(gòu):缸體、柱塞、導(dǎo)向套、鋼絲卡圈等 只能單向運(yùn)動(dòng),回程需靠外力、自重、彈簧力,需雙向運(yùn)動(dòng)時(shí),常成對使用 柱塞式液壓缸速度、推力計(jì)算 v=q/A=4q/πd F=pA=πd2?p/4 柱塞式液壓缸特點(diǎn) ∵柱塞工作時(shí)總是受壓,一般較粗 ∴水平放置易下垂,產(chǎn)生單邊磨損 故常垂直放置,有時(shí)可做成空心 又∵缸體內(nèi)壁與柱塞不接觸 ∴可不加工或只粗加工,工藝性好 故?常用于長行程機(jī)床,如?導(dǎo)軌磨床、龍門刨床、大型拉床 擺動(dòng)液壓馬達(dá)(擺動(dòng)液壓缸) 擺動(dòng)液壓缸分類:單葉片式*、雙葉片 擺動(dòng)液壓缸組成:缸體、定子塊、葉片、傳動(dòng)軸等 擺動(dòng)液壓缸工作原理:當(dāng)缸的一個(gè)油口進(jìn)壓力油,另一油口回油時(shí),葉片在壓力油作用下往一個(gè)方向擺動(dòng),帶動(dòng)軸偏轉(zhuǎn)一定角度小于3600)當(dāng)進(jìn)回油口互換時(shí),馬達(dá)反轉(zhuǎn)。
擺動(dòng)液壓缸參數(shù)計(jì)算:T=zb/8·(D-d)(p1-p2)ηm ω=8qηcv/zb(D-d) T雙=2T單·ω ω雙=1/2單 擺動(dòng)式液壓缸的特點(diǎn):結(jié)構(gòu)緊湊,輸出扭矩大,但密封困難,一般只用于中低壓系統(tǒng)。
其它形式的常用缸:增壓缸(增壓器)、多級缸(伸縮缸) 齒條活塞缸(無桿液壓缸) 增壓缸(增壓器) 增壓缸作用:得到高于泵壓的輸出壓力 增壓缸結(jié)構(gòu):單作用、雙作用 增壓缸增壓原理:A1?p1=A2?p2 p1πD/4=p2πd/4 p2=A1/A2p1=p1 D/d=Kp1K—增壓比 增壓缸特點(diǎn):在不pp的前提下,靠A來p單作用斷續(xù)增壓、雙作用連續(xù)增壓 多級缸(伸縮缸)結(jié)構(gòu):由兩個(gè)或多個(gè)活塞缸或柱塞缸套裝而成,有單作用和雙作用之分。
多級缸工作原理:活塞或柱塞伸出時(shí),從大到小,速度逐漸增大,推力逐漸減小活塞或柱塞縮回時(shí),從小到大 多級缸特點(diǎn)應(yīng)用: ∵工作時(shí)可伸很長,不工作時(shí)縮短 ∴占地面積小,且推力隨行程增加而減小 故起重機(jī)伸縮臂、自動(dòng)傾卸卡車、火箭發(fā)?射臺(tái)等皆用 齒條活塞缸(無桿液壓缸)結(jié)構(gòu):缸體、活塞、齒條、齒輪、端蓋等 無桿液壓缸工作原理:左腔進(jìn)油,右腔回油時(shí),齒條右移,齒輪帶動(dòng)工作臺(tái)逆轉(zhuǎn)。
右腔進(jìn)油,左腔回油時(shí),齒條左移,齒?輪帶動(dòng)工作臺(tái)順轉(zhuǎn)如:自動(dòng)線、磨床 90-L-075-KA-5-NN-80-L-3-C7-D-09-GBA-35-35-24 90L075KA5NN80L3C7D09GBA353524 90L075-KA-5-NN-80-L-3-S1-D-00-GBA-32-32-24
