Title:
BARREL TYPE TRANSMISSION SHAFT PERMANENT-MAGNET COUPLER FOR ADJUSTING ELECTROMAGNETIC TORQUE
Document Type and Number:
WIPO Patent Application WO/2011/018010
Kind Code:
A1
Abstract:
A barrel type transmission shaft permanent-magnet coupler for adjusting electromagnetic torque is a rotary barrel type or turntable and rotary barrel compound structure. The coupler consists of at least one group of axial magnetic field boiler-grate armature permanent-magnet coupling components (401, 402) and/or radial magnetic field squirrel-cage armature permanent-magnet coupling components (441, 442), at least one coupling mechanism of a driving permanent-magnet coupling turntable matched with a driving turntable of the permanent-magnet coupling components and corresponding driving shaft coupling joint (310), at least one coupling mechanism of a driven permanent-magnet coupling turntable matched with a driven permanent-magnet coupling turntable of the permanent-magnet coupling components and corresponding driven shaft coupling joint (311), an adjusting mechanism for adjusting air-gap spacing and coupling area of the permanent-magnet coupling turntable, and an integrated assembly mechanism making the system become an integrated structure in favor of packing, transportation and installation. The permanent-magnet coupler is suitable for technical fields of transmission shaft coupling driving, load speed regulation and power dragging.
