Title:
PERMANENT MAGNET COUPLING DEVICE FOR CYLINDRICAL TRANSMISSION SHAFT
Document Type and Number:
WIPO Patent Application WO/2010/148991
Kind Code:
A1
Abstract:
A permanent magnet coupling device for a cylindrical transmission shaft includes at least one set of an external rotor cylinder and an inner rotor cylinder, at least one external rotor cylinder coupling mechanism suitable for the external rotor cylinder, at least one inner rotor cylinder coupling mechanism suitable for the inner rotor cylinder, an input coupling (35, 135, 235, 335, 535, 635) and an output coupling (4, 104, 204, 304, 504, 604). The external rotor cylinder and the inner rotor cylinder are coupled to each other through permanent magnet air gap magnetic field (20, 120, 220, 320, 322, 321, 520, 521, 620, 621). The inner rotor cylinder is provided in the cavity inside the external rotor cylinder. A set of permanent magnet coupling components is provided on adjacent corresponding positions respectively on the external rotor cylinder and the inner rotor cylinder. The set of permanent magnet coupling components can be at least one of the followings: a set of radial air gap magnetic field coupling components and a set of axial air gap magnetic field coupling components. The external rotor cylinder and the inner rotor cylinder are connected to the corresponding input coupling (35, 135, 235, 335, 535, 635) and the corresponding output coupling (4, 104, 204, 304, 504, 604) by the suitable coupling mechanisms respectively. The device has high transmission efficiency, a simple structure, convenient installation, harsh environment resistance, shaft eccentricity tolerance, load isolation, reduced vibration and noise and a long service life.
