Abstract
A rotary bearing with a damper having an inner bearing element configured for rotation around an axis of rotation, an outer bearing element coaxial with the inner bearing element, an inner damper element with an outer surface surrounding the outer bearing element, an outer damper element with an inner surface surrounding the inner damper element, at least one sealing element provided between the outer surface and the inner surface, the sealing element confining a damper space having a circumferential film space defined by a clearance between the outer surface and the inner surface. The damper space contains fluid and is a closed, isolated damper space.
Claims23
A rotary bearing, comprising:
- an inner bearing element;
- an outer bearing element coaxial with the inner bearing element, the inner bearing element configured for rotation around an axis of rotation of the rotary bearing and relative to the outer bearing element;
- an inner damper element surrounding the outer bearing element;
- an outer damper element surrounding the inner damper element;
- and
- at least one sealing element provided between an outer surface of the inner damper element and an inner surface of the outer damper element, the sealing element confining a damper space comprising at least a film space provided by a clearance between the outer surface and the inner surface, the damper space being at least partially filled with fluid,
- wherein in an operating condition the damper space is a closed, isolated damper space,
- wherein the damper space is provided with a closable filling port, and
- wherein the damper space is partially filled with liquid and partially filled with gas.
A motor comprising a rotary bearing, the rotary bearing comprising:
- an inner bearing element;
- an outer bearing element coaxial with the inner bearing element, the inner bearing element configured for rotation around an axis of rotation of the rotary bearing and relative to the outer bearing element;
- an inner damper element surrounding the outer bearing element;
- an outer damper element surrounding the inner damper element;
- and
- at least one sealing element provided between an outer surface of the inner damper element and an inner surface of the outer damper element, the sealing element confining a damper space comprising at least a film space provided by a clearance between the outer surface and the inner surface, the damper space being at least partially filled with fluid,
- wherein in an operating condition the damper space is a closed, isolated damper space,
- wherein the damper space is provided with a closable filling port, and
- wherein the damper space is partially filled with liquid and partially filled with gas.
A rotary atomizer comprising at least one rotary bearing, the at least one rotary bearing comprising:
- an inner bearing element;
- an outer bearing element coaxial with the inner bearing element, the inner bearing element configured for rotation around an axis of rotation of the at least one rotary bearing and relative to the outer bearing element;
- an inner damper element surrounding the outer bearing element;
- an outer damper element surrounding the inner damper element;
- and
- at least one sealing element provided between an outer surface of the inner damper element and an inner surface of the outer damper element, the sealing element confining a damper space comprising at least a film space provided by a clearance between the outer surface and the inner surface, the damper space being at least partially filled with fluid,
- wherein in an operating condition the damper space is a closed, isolated damper space, and
- wherein the damper space is provided with a closable filling port, and
- wherein the damper space is partially filled with liquid and partially filled with gas.
