Document Type and Number:
WIPO Patent Application WO/2021/192334
Kind Code:
A1
Abstract:
According to the present embodiment, a sliding bearing unit is provided with: a fixed shaft including a radial bearing surface; a rotor; and a liquid metal. The rotor includes a first cylinder and a second cylinder. The second cylinder includes another radial bearing surface, and rotational movement of the second cylinder is restricted so as not to rotate relative to the first cylinder. The liquid metal forms a dynamic pressure type radial sliding bearing along with the radial bearing surface and the other radial bearing surface.
