WIPO Patent Application WO/2024/084988
Kind Code:
A1
Abstract:
Provided is a rotation transmission device. The rotation transmission device comprises: a shaft body extending in a predetermined direction, a rotor, a housing, a stator, a bearing, and at least one magnetic fluid seal. At least one magnetic fluid seal is configured to close an internal space surrounded by the housing, at a sealing position, by interposing a magnetic fluid between the shaft body and the housing over the entire circumference around an axis. The rotation transmission device is configured to rotate the shaft body together with the rotor by causing a current to flow to the stator in a state in which a rotating object is attached to the shaft body, and thereby transmit the rotation to the rotating object.
