Title:
ELECTROMAGNETIC BRAKE DEVICE
Document Type and Number:
WIPO Patent Application WO/2006/103727
Kind Code:
A1
Abstract:
A deenergization operation type electromagnetic brake device (1), comprising a plurality of conical springs (8) for pressing an armature disk (5) against a fixed disk (7) through a friction disk (6) held therebetween. The conical springs (8) are inserted into the spring insertion recessed parts (15) of the yoke (11) of an electromagnet (4), and held between the bottom faces of the recessed parts and the armature disk (5) in a compressed state. Since the conical springs (8) are shorter than cylindrically coiled springs in a compressed state, the spring insertion recessed parts (15) can be made shallower and the thickness of the yoke (11) determined by the recessed parts can be reduced. As a result, the electromagnetic brake device (1) can be advantageously formed flat.
