style="text-indent:25px">氣彈簧（gasspring）是一種可以起支撐、緩沖、制動、高度調(diào)節(jié)及角度調(diào)節(jié)等功能的工業(yè)配件。它由以下幾部分構(gòu)成：壓力缸、活塞桿、活塞、密封導向套、填充物（惰性氣體或者油氣混合物），缸內(nèi)控制元件與缸外控制元件（指可控氣彈簧）和接頭等。原理是在密閉的壓力缸內(nèi)充入惰性氣體或者油氣混合物，使腔體內(nèi)的壓力高于大氣壓的幾倍或者幾十倍，利用活塞桿的橫截面積小于活塞的橫截面積從而產(chǎn)生的壓力差來實現(xiàn)活塞桿的運動。由于原理上的根本不同，氣彈簧比普通彈簧有著很明顯的優(yōu)點：速度相對緩慢、動態(tài)力變化不大（一般在1：1.2以內(nèi)）、容易控制；缺點是相對體積沒有螺旋彈簧小，成本高、壽命相對短。</p><p style="text-indent:25px">大彈簧又名熱卷彈簧，生產(chǎn)過程采用熱卷工藝。用彈性材料制成的零件在外力作用下發(fā)生形變，除去外力后又恢復原狀。一般用彈簧鋼制成。大彈簧一般線徑很大，在加熱后容易扭曲成形，回彈性較小，成型后需淬火后回火處理。大彈簧能夠在載荷作用下發(fā)生較大的彈性變形，在各類機械中運用非常普遍。彈簧是機械和電子行業(yè)中普遍使用的一種彈性元件，彈簧在受載時能產(chǎn)生較大的彈性變形，把機械功或動能轉(zhuǎn)化為變形能，而卸載后彈簧的變形消失并回復原狀，將變形能轉(zhuǎn)化為機械功或動能。膜片彈簧:
