JCZ制动器装置形式概述1.JCZ系列交流制动器,是通过摩擦时,使回转机构停止运动的一种机械制动装置,此种制动力矩产生是由电磁忒操纵制动来实现,制动力矩的大小可用弹簧进行调节。
2.制动器主要由底座、支柱、闸瓦、调整杆、弹簧组成、闸瓦与支柱、支柱与底座都是轴销连接,可在一定范围倾斜或转动,主弹簧安装在支柱的上部。
3.电磁铁安装在调整杆的一端,当其通电动作时,带动调整杆使主弹簧压缩,这时两片闸瓦即张开,回转机构可以正常运行。当电磁铁通电时带动调整杆向反方向移动.这时主弹簧之弹性压力将闸瓦紧压向回转的制动轮上,而使机构停止运动。
4.制动闸瓦工作表面采用石棉刹车材料制成。
5.本制动器出厂不包括电磁铁部分,用户选用时需按型号另行定购。
