ELECTROMAGNETIC-RELEASED, MULTI-DISC ENCLOSED SAFETY BRAKE

An electromagnetic-released, multi-disc, enclosed safety brake for primary use in offshore marine winch applications. A stationary coil housing encompasses springs that apply pressure to an armature, a pair of separator plates, three friction plates and a stationary endplate. The multi-disc brake is released by means of a DC voltage applied to the brake coil. The excited coil generates an electromagnetic force that attracts the armature across an air-gap thus reducing the spring force applied to the disc pack. The brake is applied when the DC voltage is removed from the brake coil. Various structures and methodologies for reducing vibrations in the brake are also provided. 本申请公开种主要用于近海海洋绞车应用的电磁释放式多盘封闭安全制动器。静止线圈壳包围向电枢施加压力的弹簧、对隔板、三个摩擦板和静止端板。多盘制动器借助施加到制动器线圈的DC电压释放。激励线圈生成吸引电枢跨过空气间隙的电磁力，从而减少施加到盘片组的弹簧力。当从制动器线圈去除DC电压时，应用制动器。还提供了用于减少制动器中的振动的各种结构和方法。
