Abstract
This rotating shaft structure comprises a first link, a second link connected to the first link, and a plurality of speed reducers positioned between the first link and the second link. At least one of a speed-reducer-side attachment hole and a first-link-side attachment hole, which are for joining the speed reducers to the first link, is larger or longer than the other.
Claims10
A rotating shaft structure comprising:
- a first link;
- a second link connected to the first link;
- and
- a plurality of speed reducers positioned between the first link and the second link,
- wherein one of a speed reducer side attachment hole and a first link side attachment hole configured to connect the speed reducer to the first link is larger than the other attachment hole or an elongate hole.
A manufacturing method of a rotating shaft structure comprising a first link, a second link connected to the first link, and a plurality of speed reducers positioned between the first link and the second link, the method comprising the steps of
- forming one of a speed reducer side attachment hole and a first link side attachment hole configured to connect the speed reducer to the first link so that the one attachment hole is larger than the other attachment hole or an elongate hole;
- previously adjusting the positional relationship between the speed reducer side attachment hole and the first link side attachment hole by attaching the plurality of speed reducers to the second link;
- attaching one of the speed reducers attached to the second link to the first link;
- inserting a drive shaft configured to drive the speed reducer into the speed reducer while rotating the drive shaft;
- and
- attaching the remaining speed reducer to the first link while a position of the speed reducer side attachment hole is displaced due to the insertion of the drive shaft.
