MAGNETIC TORQUE ADJUSTABLE TRANSMISSION SHAFT PERMANENT-MAGNET COUPLING TRANSMISSION AND SPEED REGULATION DEVICE

摘要

A magnetic torque adjustable transmission shaft permanent-magnet coupling transmission and speed regulation device is of a rotating disc type structure, a revolving barrel type structure or a composite type structure of a rotating disc and a revolving barrel. It is composed of at least one group of axial magnetic field permanent-magnet coupling modules (401, 402) or/and radial magnetic field permanent-magnet coupling modules (441, 442), at least one pack of a driving permanent-magnet coupling rotating disc coupling mechanism and a corresponding driving shaft coupling joint (310) which are suitable for a driving rotating disc in the permanent-magnet coupling modules, at least one pack of a driven permanent-magnet coupling rotating disc coupling mechanism and a corresponding driven shaft coupling joint (311) which are suitable for a driven permanent-magnet coupling rotating disc in the permanent-magnet coupling modules, a pack of air gap interval and coupling area regulating mechanisms of the permanent-magnet coupling rotating disc and a pack of integrated assembly mechanisms (315、317) which integrates the system into an integrated structure convenient for package, transportation and installation. The device is suitable for technical fields of transmission shaft coupling driving, load speed regulation and power dragging.
