2、 1 液壓系統(tǒng) 液壓傳動和氣壓傳動稱為流體傳動，是根據(jù) 17 世紀帕斯卡提出的液體靜壓力傳動原理而發(fā)展起來的一門新興技術(shù)， 1795 年英國約瑟夫布拉曼 (749在倫敦用水作為工作介質(zhì)，以水壓機的形式將其應(yīng)用于工業(yè)上，誕生了世界上第一臺水壓機。 1905 年將工作介質(zhì)水改為油，又進一步得到改善。 第一次世界大戰(zhàn) (1914液壓傳動廣泛應(yīng)用，特別是 1920 年以后，發(fā)展更為迅速。液壓元件大約在 19 世紀末 20 世紀初的 20 年間，才開始進入正規(guī)的工業(yè)生產(chǎn)階段。 1925 年 維克斯 (明了壓力平衡式葉片泵 ,為近代液壓元件工業(yè)或液壓傳動的逐步建立奠。

10、附件 1：外文資料翻譯譯文 1 液壓傳動概述 液壓傳動的發(fā)展概況 壓傳動的定義 一部完整的機器是由原動機部分、傳動機構(gòu)、控制部分及工作機部分組成。原動機有幾種類型，例如電動機、內(nèi)燃機等。工作機即完成該機器的工作任務(wù)的直接工作部分，如剪床的剪刀，車床的刀架、車刀、卡盤等。由于原動機的功率和轉(zhuǎn)速比是被限制的，為了覆蓋工作機較大范圍的工作力和工作速度的變化，以及操作性能的要求，在原動機和工作機之間設(shè)置了傳動機構(gòu)，其作用是把原動機輸出功率經(jīng)過變換后傳遞給工作機。 傳動機構(gòu)通常分為電氣傳動、 機械傳動和流體傳動三類。
