  • 液压(ya)传动的优点

    液(ye)压(ya)传(chuan)(chuan)动(dong)可(ke)以(yi)输出大(da)的推力(li)或大(da)的转矩(ju),可(ke)实现低速大(da)T位运动(dong),在(zai)是其它传(chuan)(chuan)动(dong)方(fang)式所(suo)不能比的突出优(you)点。液(ye)压(ya)传(chuan)(chuan)动(dong)能很方(fang)便地实现调速,调速范围(wei)大(da),且可(ke)在(zai)系统运行过程中调速。在(zai)相同功率条件下(xia),液(ye)压(ya)传(chuan)(chuan)动(dong)装置体积小,重(zhong)量轻,结构紧凑。

  • 千(qian)斤(jin)顶的(de)工作原理

    机械(xie)千斤顶(ding)(ding)和液压(ya)千斤顶(ding)(ding)等,原(yuan)(yuan)理各有不同(tong)(tong)。从原(yuan)(yuan)理上来说,液压(ya)传(chuan)动所(suo)基于的(de)基本的(de)原(yuan)(yuan)理就(jiu)(jiu)是(shi)帕斯卡(ka)定律,也就(jiu)(jiu)是(shi)说,液体各处的(de)压(ya)强是(shi)一(yi)致的(de)。这(zhei)(zhei)样(yang),在平衡的(de)系(xi)统(tong)中,比较(jiao)(jiao)小的(de)活(huo)塞上面施(shi)加(jia)的(de)压(ya)力(li)比较(jiao)(jiao)小,而(er)(er)大(da)(da)的(de)活(huo)塞上施(shi)加(jia)的(de)压(ya)力(li)也比较(jiao)(jiao)大(da)(da),这(zhei)(zhei)样(yang)能(neng)够保持液体的(de)静止。所(suo)以通(tong)过液体的(de)传(chuan)递(di),可(ke)以得(de).到不同(tong)(tong)端(duan)上不同(tong)(tong)的(de)压(ya)力(li),就(jiu)(jiu)可(ke)以达到一(yi)个变换的(de)目(mu)的(de)。人们所(suo)常见到的(de)液压(ya)千斤顶(ding)(ding)就(jiu)(jiu)是(shi)利用了这(zhei)(zhei)个原(yuan)(yuan)理来达到力(li)的(de)传(chuan)递(di)。螺旋千斤顶(ding)(ding)以往复扳(ban)动手柄,拔爪即推动棘轮间隙回转,小伞齿(chi)轮带动大(da)(da)伞齿(chi)轮,使举重(zhong)螺杆旋转,从而(er)(er)使升(sheng)(sheng)降套筒获得(de)起升(sheng)(sheng)或下降,而(er)(er)达到起重(zhong)拉(la)力(li)的(de)功能(neng),但不如液压(ya)千斤顶(ding)(ding)简(jian)易(yi)。
