Abstract
A rotor bearing assembly for an underwater generator of a fluid flow power plant includes a hollow cylindrical bearing carrier configured to be inserted into an interior of a rotor and releasably connected to the rotor such that they rotate together and an axle journal extending into an interior of the bearing carrier and rotatably supporting the bearing carrier. The bearing the axle journal and the bearing carrier are configured as an installation unit such that a portion of the bearing carrier is insertable into the rotor interior and removable from the rotor interior while attached to the axle journal. Also a generator including the rotor bearing assembly.

A rotor bearing assembly for an underwater generator of a fluid flow power plant, the bearing assembly comprising:
- a hollow cylindrical bearing carrier configured to be inserted into an interior of a rotor and releasably connected to the rotor such that they rotate together, and
- an axle journal extending into an interior of the bearing carrier and rotatably supporting the bearing carrier,
- wherein the axle journal and the bearing carrier are configured as a watertight installation unit configured to be at least partially inserted into the rotor interior and removable from the rotor interior while attached to the axle journal.
A rotor bearing assembly for an underwater generator of a fluid flow power plant, the bearing assembly comprising:
- a hollow cylindrical bearing carrier configured to be inserted into an interior of a rotor and releasably connected to the rotor such that they rotate together, and
- an axle journal extending into an interior of the bearing carrier and rotatably supporting the bearing carrier,
- wherein the bearing the axle journal and the bearing carrier are configured as an installation unit such that a portion of the bearing carrier is insertable into the rotor interior and removable from the rotor interior while attached to the axle journal,
- wherein the bearing carrier is rotatably supported on the axle journal by a rolling-element bearing,
- wherein the rolling-element bearing includes an inner ring attached to the axle journal to rotate with the axle journal and an outer ring attached to the bearing carrier to rotate with the bearing carrier,
- wherein the bearing carrier includes a radially extending first flange having a plurality of first through openings by which the bearing carrier is connectable to the rotor,
- wherein the axle journal includes a radially extending second flange configured to be connected to a stationary generator housing, and
- wherein the second flange includes a plurality of second through-openings.
