產品詳情




LLA型無骨架輪胎式聯軸器是一種高彈性聯軸器,具有良好的減震緩沖和的軸間偏移補償性能,工作溫度—20~80攝氏度,轉遞轉矩10~20000N.M,適于潮濕、多塵、有沖擊、振動、正反轉多變和起動頻繁的工作條件,并全拆裝方便,不需潤滑、。

LLA型無骨架輪胎式聯軸器由兩個帶軸孔的法蘭和橡膠輪胎體組成,具有優良的軸偏移補嘗性和緩沖減震性能。有較,扭轉剛度小,減振,補償量較大,有良好的阻尼,結構簡單,不用潤滑,裝拆維護方便.噪聲小,徑向尺寸大,承載能力低,過載時產生較大軸向附加載荷,使用壽命取決于橡膠產品質量,適用于起動頻繁,正反轉多變、沖擊振動較大的軸系傳動,可在有粉塵、水份工況環境下工作,不適用于高溫、高速、大轉矩和低速重載工況條件。  

輪胎聯軸器分為凸型和凹型兩大類,凸型又分為帶骨架整體式,無骨整體式和徑向切口式三種。它們的共同特點都是將輪胎環用螺栓來連接兩半聯軸器以實現兩軸的連接.輪胎環內側用硫化方法與鋼質骨架粘接成一體,骨架上的螺栓孔處焊有螺母。裝配時用螺栓與兩半聯軸器的凸緣連接,依靠擰緊螺栓使輪胎與凸緣端面之間產生的摩擦力來傳遞轉矩,輪胎環工作時發生扭轉剪切變形,故輪胎聯軸器具有很高的彈性,補償兩軸相對位移的能力較大,并有良好的阻尼,而且結構簡單、不需潤滑、裝拆和維護都比較方便。
