Abstract
A bearing arrangement for guiding a motor shaft for supporting axial and/or radial forces of a vertical turbine pump. The bearing arrangement includes a bearing comprising an inner ring which can be non-rotatably connected to the motor shaft and an outer ring, an oil sump filled with an oil, within which the bearing is arranged at least partially immersed in the oil, and an inner oil deflector which is non-rotatably connected to the inner ring and deflects oil conveyed between the inner ring and the outer ring back into the oil sump as a result of rotation of the bearing.
Claims12
A bearing arrangement for guiding a motor shaft and/or for supporting axial and/or radial forces of a vertical turbine pump, the bearing arrangement comprising:
- a bearing comprising an inner ring which can be non-rotatably connected to the motor shaft, and an outer ring;
- an oil sump filled with an oil, within which the bearing is arranged at least partially immersed in the oil;
- and
- an inner oil deflector which is non-rotatably connected to the inner ring and deflects oil conveyed between the inner ring and the outer ring as a result of a rotation of the bearing back into the oil sump;
- and
- an outer wall which radially delimits the oil sump and at which the outer ring is provided;
- wherein a collecting pan for collecting the oil deflected by the inner oil deflector which, in an axial plan view, extends around the outer ring, is provided between the outer wall and the outer ring;
- and
- wherein a plurality of spaced apart axially extending connecting openings for draining oil collected in the collecting pan into the oil sump are provided between the collecting pan and the oil sump.
