The invention belongs to the technical field of traction machines, and discloses a traction machine brake which comprises a machine base, a magnet yoke, a brake assembly and an elastic piece. The machine base is in clearance fit with the brake assembly, and the brake assembly can reciprocate relative to the machine base. The braking assembly comprises an armature and a braking part matched with the armature, the armature can move to drive the braking part to move to brake the traction machine or release braking of the traction machine, the armature is located between the machine base and the magnet yoke, and an elastic part is arranged between the armature and the magnet yoke; the base extends to the position of the magnet yoke and is connected with the magnet yoke through a fastener. The traction machine brake can effectively avoid the problem that the braking function of the brake fails due to the fact that a fastener breaks and fails, and therefore the safety accident that an elevator cannot be braked is effectively reduced.
本发明属于曳引机技术领域,公开了一种曳引机制动器,包括机座、磁轭、制动组件和弹性件;机座与制动组件间隙配合,且制动组件能够相对机座往复移动;制动组件包括衔铁以及与衔铁配合设置的制动件,衔铁运动能够带动制动件活动至制动曳引机或解除对曳引机的制动,衔铁位于机座和磁轭之间,且衔铁与磁轭之间设置有弹性件;机座延伸至磁轭的位置并通过紧固件与磁轭连接。该曳引机制动器能够有效避免紧固件断裂失效导致的制动器制动功能失效的问题,从而有效降低电梯不能制动的安全事故。
