【発明の名称】無励磁作動型電磁ブレーキ
Document Type and Number:
Japanese Patent JP3384230
Kind Code:
B2
Abstract:
This invention provides with a type of non-exciting solenoid brake device which can prevent unstable condition as releasing the brake. The problem is attributable to a slight turn of armature in the gap between armature and the armature assembly creating vibration. An arch-shaped ring and thrust nut assembly is installed on the outside of shaft opposing the armature gap, exerting predetermined pressure on the armature in the direction of the solenoid assembly, and, if required, an elastic hollow rubber cone forming a parallelogram can be inserted in between the external shell surface and the inner surface of armature to make them fit with an angle.
