Abstract
Disclosed is a rotatable-and-swingable type of rotary joint device according to the present invention comprises at least an input shaft rotatably fixed to the casing of the device, a precession spherical body responsive to the rotation of the input shaft for rotating and swinging, and an output shaft operatively connected to the precession spherical body for rotating. This arrangement permits the crossing of the input and output shafts to change freely within certain angular limits, thereby substantially increasing the versatility of designing, and contributing to the down-sizing of the drive transmission.

A rotatable-and-swingable type of rotary joint device comprising at least
- a casing of the device,
- an input shaft rotatably fixed to the casing of the device,
- a precession spherical body responsive to the rotation of the input shaft for rotating and swinging, and
- an output shaft operatively connected to the precession spherical body for rotating.
A rotatable-and-swingable type of speed-reduction device comprising:
- a casing of the device,
- an input shaft rotatably fixed to the casing of the device,
- a precession spherical body operatively connected to the input shaft via an associated input swing axle to be responsive to the rotation of the input shaft for rotating and swinging,
- a stationary input guide block operatively connected to and supporting the precession spherical body,
- a precession output intervenient member operatively connected to the precession spherical body,
- a stationary output guide block fixed to the casing of the device, operatively connected to and rotatably and swingably supporting the output intervenient member, and
- an output shaft rotatably supported by the stationary output guide block, and operatively connected to the precession output intervenient member for rotation.
