Title:
ARMATURE ROTOR FOR ELECTROMAGNETIC RETARDER
Document Type and Number:
Japanese Patent JPS61244258
Kind Code:
A
Abstract:
1. An electromagnetic retarder armature rotor comprising at least one disk (2) arranged to move opposite of the inductor stator from which it is separated by an air gap (E), said disk being connected to a fixing ring (7) by a crown of arms (9, 91 ) forming ventilation fins, the largest diameter portions of these arms projecting axially from the face, of the disk, which is the farthest from the air gap and their peaks being joined together by an annular flange (10), the external face of which is exposed to the free air in the completed retarder, the assembly formed by the disk, the ring, the arms and the flange being formed as a single molded block, characterized in that some at least of the arm portions (9) which connect the flange (10) to the disk (2) are split into two parallel walls (12) defining a narrow elongate pocket (13) whose bottom is formed by the disk and which emerges axially in the free face of the flange through a slit (14) formed in this flange.
