Title:
MAGNET COUPLING TYPE DRIVE DEVICE, AND VENTILATION DEVICE AND MIST GENERATING DEVICE USING THE SAME
Document Type and Number:
Japanese Patent JP2023083012
Kind Code:
A
Abstract:
To provide a mist generating device using a magnet coupling type drive device reducing vibrations or noise of a rotary shaft.SOLUTION: One end on a partition wall 2a side of a rotary shaft 13 has a projection, and the partition wall 2a opposing to the projection has a curved recess abutting on the projection. Therefore, even if rotation centers of a motor shaft 32 and the rotary shaft 13 are deviated, when rotated by magnet-coupling, the rotary shaft 13 is moved to the lowermost part of the recess by attraction force of magnetism to match the rotation center with that of the motor shaft 32, so that the deviation of the rotation center axis is suppressed to stable rotations, and vibrations or noise due to axial deviation can be reduced.SELECTED DRAWING: Figure 5
