Abstract
A rotary drive device includes a pair of drive force transmissions, a pair of decelerators, a pair of carriers, and at least one coupler. Driving rollers are included in the pair of drive force transmissions. Driving rollers transmit drive force to a main wheel. The main wheel includes driven rollers. The pair of drive force transmissions are rotatable about a rotation axis. The pair of carriers accommodate at least a portion of the decelerators. The pair of carriers oppose each other in an axial direction along the rotation axis. The pair of carriers include a first carrier and a second carrier that are directly or indirectly coupled by the at least one coupler.
Claims12
A rotary drive device, comprising:
- a pair of drive force transmissions in which a plurality of driving rollers transmitting drive force to a main wheel including a plurality of driven rollers are provided, the drive force transmissions being rotatable about a rotation axis;
- a pair of decelerators to decelerate a rotation speed of an input shaft and rotating the drive force transmission at a decelerated rotation speed;
- a pair of carriers accommodating at least a portion of the decelerator and opposing each other in an axial direction along the rotation axis;
- and
- at least one coupler;
- wherein
- the pair of carriers include a first carrier and a second carrier;
- the first carrier and the second carrier are directly coupled by the at least one coupler;
- the first carrier includes a through hole into which the at least one coupler can be inserted;
- the second carrier includes a screw hole into which the at least one coupler can be threaded;
- the through hole and the screw hole are positioned at positions opposing each other in the axial direction;
- and
- the at least one coupler includes a coupler which penetrates through portions of both the first carrier and the second carrier.
