意大利UNIVER氣缸編碼OV1000320350

無桿氣缸和普通氣缸的的工作原理一樣只是外部連接、密封形式不同
缸兩邊都是空心的活塞杄內的永磁鐵帶動活塞桿外的另一個磁體(運動部件)我想說的是
它對清潔度要求蠻高的我們公司的磁偶的無桿氣缸經常要拆下來汽油清洗可能與它的工作環
境有關吧。
桿氣缸里有活塞,而沒有活塞桿的,活塞裝置在導軌里,外部負載給活塞相連,作動靠
磁偶式的運動是利用空心活塞杄內的永磁鐵帶動活塞杄外的另一個磁鐵運動來實現的,因其在
速度快,負載高時內外磁環易脫開,故現在比較少用了。其負載質量的大小需查找其質量與速
度的特性曲線。現在機械式的用的比較多。
無桿氣缸的分類
無桿氣缸分為磁偶無桿氣缸和機械接觸式無桿氣缸。無桿氣缸是指利用活塞直接或方式連接外
界執行的機械,并使其跟隨活塞實現往復運動的氣缸,這種氣缸的zui大優點是節省安裝空間
(1)磁偶無桿氣缸
活塞通過磁力帶動缸體外部的移動體做同步移動。它的工作原理:在活塞上安裝一組高強
磁性的永久磁環,磁力緯通過薄壁缸筒與套在外面的另一組磁環作用,由于兩組磁環磁性相
反,具有很強的吸力。當活塞在缸筒內被氣壓推動時,則在磁力作用下,帶動缸筒外的磁環套
起移動。氣缸活塞的推力必須與磁環的吸力相適應。
(2)機械接觸式無桿氣缸
在氣缸缸管軸向開有一條槽,活塞與尚志在槽上部移動。為了防止泄漏及防塵需要,在開
口部采用不銹鋼封帶和防塵不銹鋼帶固定在兩端缸蓋上,活塞架穿過槽地,把活塞與尚志連成
體。活塞與尚志連接在一起,帶動固定在尚志上的執行機構實現往復運動,
桿氣缸特點
1、與普通氣缸相比,在同樣行程下可縮小1/2安裝裝置
不需設置防轉機械
適用于缸徑10-80mm,zui大行程可達415
速度10m/s
桿氣缸缺點
1、密封性能差,容易產生外漏。在使用三位閥時必須選用中壓式
受負載力小,為了增加負載能力,必須增加導向機械。無桿氣缸實例無桿氣缸的品牌
現在市場上流通的無桿氣缸主要有ORGA無桿氣缸、諾冠無桿氣缸、 FESTO無桿氣缸、SMC
無桿氣缸、小金井等,這幾個品牌還是不錯的。其中 ORIGA的產品線比較少,是專業做無桿
氣缸,也是無桿氣缸的發明者,擁有金屬密封的專利技術,但整體上的知名度有時比不上其他
幾個。
