<p>The invention relates to a brake having noise elimination function and the execution mode of the invention relates to the brake of an elevator winch. The brake allows the brake switch to have more accurate detecting precision with low motion noise and have noise elimination function. The brake comprises an armature able to leave or contact with the rotary cylinder, a spring which exerts force upon the rotary cylinder from armature direction, thus to press the brake sheets upon the rotary cylinder, an electromagnet which overcomes the application of force of the spring, attracts the armature to the direction off the rotary cylinder, and magnetically fixes the armature, and a noise elimination member which reduces the collision noise resulting from the magnetic fixation of the armature and reduces the noises when the brake sheet contacts with the rotary cylinder.</p> |
