連桿機(jī)構(gòu)

1、- 1 - 連桿機(jī)構(gòu) 連桿存在于車庫門裝置，汽車擦裝置，齒輪移動裝置中。它是一給予很少關(guān)注的機(jī)械工程學(xué)的組成部分。 聯(lián)桿是具有兩個或更多運(yùn)動副元件的剛性機(jī)構(gòu)，用它的連接是為了傳遞力或運(yùn)動 。在每個機(jī)器中， 在運(yùn)動期間，聯(lián)桿或者占據(jù)一相對于地面的固定位置或者作為一個整體來承載機(jī)床 。這些連桿是機(jī)器主體被稱為固定連桿。 基于由循環(huán)的或滑動的分界面的元件連接的布局被稱作連接 。 這類旋轉(zhuǎn)的和菱形的連接機(jī)構(gòu)被稱作低副 。 高副基于接觸點(diǎn)或彎曲分界面的 。低 副的例子包括鉸鏈循環(huán)的軸承和滑道以及萬向接頭 。高 副的例子包括通。
