Document Type and Number:
WIPO Patent Application WO/2007/108489
Kind Code:
A1
Abstract:
A deenergization type electromagnetic brake that is reduced in size and weight
while increasing or maintaining a brake torque without increasing the outer
diameter of the brake. The deenergization type electromagnetic brake (20) has
a flat plate-like disk (22) that is positioned vertical to a rotating shaft (1)
to be braked and is fixed to the rotating shaft (1) so as to be integrally rotatable
with a hub (21) disposed in between them, a yoke (23) that is disposed on one side
of the disk (22), an armature (24) that is axially movably and non-rotatably disposed
between the disk (22) and the yoke (23), and a cup-like shell (25) that is disposed
and fitted to the outer periphery of the yoke (23) while covering both the disk
(22) and the armature (24). The yoke (23) has an exciting coil (23c) and a coiled
spring (23e). The shell (25) is secured to the yoke by pins (26) such that their
head end faces do not project from the outer peripheral surface of the yoke.
