ードをつくることができる。First, in the case of high-speed drive, only the high-speed motor 21& rotates. At this time, the low speed motor 21b is stopped. Furthermore, the low-speed worm 23 and the sun gear 26 are in a self-locking relationship (the worm cannot be rotated from the gear side), and the sun gear 26 does not rotate. High speed motor 21
The internal gear 24 rotates as the gear 1L rotates, and the rotational motion around the gear 28 meshed with it is extracted as an output by the output pulley 27 engaged with the shaft 28. In addition, in the case of low-speed drive, the operation is completely opposite to the above, and the low-speed morph 21b
211L and stop the high-speed motor 211L. At this time, the relationship between the high speed worm 22 and the internal gear 24 is also a self-locking relationship as described above. When the low speed motor 21b rotates, the sun gear 26 rotates, the planetary gear 26 meshing therewith rotates, and the output pulley 27 rotates. A wire rope 31 is wound around this output pulley 27, and the driven body is driven at variable speeds by the wire rope. Of course, the output pulley, which is the output medium, may be a gear that directly drives a rack attached to the driven body. Switching between high speed and low speed is done by turning the motor 0N-OFF.
Do it with Further, by rotating the high speed motor 211L and the low speed motor 21b at the same time, it is possible to create a super high speed mode that is even faster than the high speed mode.
