BARREL TYPE TRANSMISSION SHAFT PERMANENT-MAGNET COUPLER WITH ADJUSTABLE MAGNETIC FIELD R-GAP SEPARATION AND COUPLING AREA

摘要

A barrel type transmission shaft permanent-magnet coupler with adjustable magnetic field air-gap separation and coupling area has a barrel type or barrel-turntable complex type configuration. Said coupler comprises at least a set of axial magnetic field armature winding permanent-magnet coupling assembly (510, 511, 535, 536) and/or radial magnetic field armature winding permanent-magnet coupling assembly (850, 851, 855, 856), at least a driving permanent-magnet coupling turntable coupling mechanism and corresponding driving shaft coupler (310) adapting for a driving turntable of the permanent-magnet coupling assembly, at least a driven permanent-magnet coupling turntable coupling mechanism and corresponding driven shaft coupler (311) adapting for a driven permanent-magnet coupling turntable of the permanent-magnet coupling assembly, a permanent-magnet coupling turntable air-gap separation and coupling area adjusting mechanism, and an integration assembling mechanism (315, 317) that makes the system into an integration structure so as to be convenient for packing, transporting and installing. Said coupler can be applied to a transmission shaft coupling drive technical field, a loading speed adjusting technical field and a power dragging technical field.
