Title:
POWER TRANSMISSION DEVICE
Document Type and Number:
Japanese Patent JP2019100452
Kind Code:
A
Abstract:
To provide a power transmission device which suppresses wear when switching an output destination and which is smoothly switchable.SOLUTION: A rotary main shaft 11 has a magnetic flux generating part 12 on a side surface in the central part. A first rotor 41 and a second rotor 51 have a cylindrical shape and the rotary main shaft 11 is inserted inside, and they are provided rotatably around the rotary main shaft 11. The first rotor 41 is provided in a manner slidable along the elongation direction of the rotary main shaft 11 between a first rotation position where rotational power is transmittable with each other with the rotary main shaft 11 by a magnetic action of a magnetic flux generating part 12 by covering the magnetic flux generating part 12, and a first stop position separated from the magnetic flux generating part 12. The second rotor 51 is provided in a manner slidable along the elongation direction of the rotary main shaft 11 between a second rotation position where rotational power is transmittable with each other with the rotary main shaft 11 by a magnetic action of the magnetic flux generation part 12 by covering the magnetic flux generating part 12, and a second stop position separated from the magnetic flux generating part 12.SELECTED DRAWING: Figure 1
