    JCZ制動器裝置形式概述1.JCZ系列交流制動器,是通過摩擦時,使回轉機構停止運動的一種機械制動裝置,此種制動力矩產(chǎn)生是由電磁忒操縱制動來實現(xiàn),制動力矩的大小可用彈簧進行調(diào)節(jié)。
    2.制動器主要由底座、支柱、閘瓦、調(diào)整桿、彈簧組成、閘瓦與支柱、支柱與底座都是軸銷連接,可在一定范圍傾斜或轉動,主彈簧安裝在支柱的上部。
    3.電磁鐵安裝在調(diào)整桿的一端,當其通電動作時,帶動調(diào)整桿使主彈簧壓縮,這時兩片閘瓦即張開,回轉機構可以正常運行。當電磁鐵通電時帶動調(diào)整桿向反方向移動.這時主彈簧之彈性壓力將閘瓦緊壓向回轉的制動輪上,而使機構停止運動。
    4.制動閘瓦工作表面采用石棉剎車材料制成。
    5.本制動器出廠不包括電磁鐵部分,用戶選用時需按型號另行定購。
