Title:
PERMANENT MAGNET COUPLING DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/148990
Kind Code:
A1
Abstract:
A permanent magnet coupling device comprises an armature winding rotor disk (10, 110, 111, 410), an armature winding disk coupling mechanism (6-9, 43, 106-109, 143), a permanent magnet rotor disk (20, 120, 420), a permanent magnet disk coupling mechanism (39, 40, 147-152), an input coupling (34, 35, 134, 135) and an output coupling (31, 32, 132, 153). The armature winding rotor disk is composed of an armature winding (2, 102, 202, 402) and an armature winding installation disk (1, 101, 201, 211, 260, 301, 311, 401, 411), and the permanent magnet rotor disk is composed of a set of permanent magnets (5, 205, 405) and a permanent magnet installation disk (4, 104, 204, 304, 404). The permanent magnets are disposed on the circumference of the permanent magnet installation disk in the manner of polarities staggered. The armature winding rotor disk and the permanent magnet rotor disk between which an air gap (12, 112) is provided are coaxially disposed face to face. The armature winding rotor disk and the permanent magnet rotor disk are connected to the corresponding input coupling and output coupling by suitable coupling mechanisms respectively. The invention has high transmission efficiency, a simple structure and convenient installation.
