Abstract
A coupling apparatus (4) for connecting two rotatable shafts (2a, 3a) of a turbocompressor (1) includes a first and a second coupling part (4a, 4b) which form part of the shaft (2a, 3a) or are designed for firm connection to one end section of the shafts (2a, 3a) each. A third coupling part (4c) is designed in disc-shape and is arranged between the first and the second coupling part (4a, 4b). The first, second and third coupling part (4a, 4b, 4c) are firmly connectable to one another. The third coupling part (4c) has a section (41) which projects beyond the first or second coupling part (4a, 4b) in the radial direction and is designed as a bearing disc of an axial bearing (7).
Claims20
A coupling apparatus for connecting two rotatable shafts of a turbocompressor, the coupling apparatus comprising:
- a first coupling part connected to one of the two rotatable shafts or forming a part of said one of the two rotatable shafts;
- a second coupling part connected to the other of the two rotatable shafts or forming a part of said other of the two rotatable shafts;
- a third coupling part having a disc-shape and arranged between said first and said second coupling part with said first, said second and said third coupling part being firmly connectable to one another, and with said third coupling part having a section which projects beyond the first or second coupling part in a radial direction to form a bearing disc of an axial bearing, said third coupling part being designed as a disc without a bore at its center.
A turbocompressor comprising:
- a first rotatable turbocompressor shaft;
- a second rotatable turbocompressor shaft;
- and
- a coupling apparatus including a first coupling part connected to said first rotatable shaft or forming a part of said first rotatable shaft, a second coupling part connected to said second rotatable shaft or forming apart of said second rotatable shaft and a third coupling part having a disc-shape and arranged between said first and said second coupling part with said first, said second and said third coupling part being firmly connectable to one another, and with said third coupling part having a section which projects beyond the first or second coupling part in a radial direction, said third coupling part being designed as a disc without a bore at its center.
A turbocompressor according to claim 10, wherein:
- said axial bearing is an electromagnetic axial bearing and includes an electromagnet forming a part of said axial beating, said electromagnet being arranged adjacent to said third coupling part.
A turbocompressor comprising:
- a first rotatable turbocompressor shaft;
- a second rotatable turbocompressor shaft with at least one radial turbocompressor;
- a coupling apparatus including a first coupling part one of connected to said first rotatable turbocompressor shaft or forming a part of said first rotatable turbocompressor shaft, a second coupling part one of connected to said second rotatable turbocompressor shaft or forming a part of said second rotatable turbocompressor shaft and a third coupling part slaving a disc-shape and arranged between said first and said second coupling part with said first, said second and said third coupling part being firmly connectable to one another, and with said third coupling part having a section which projects beyond the first or second coupling part in a radial direction;
- and
- an axial bearing formed with said section which projects beyond the first or second coupling part in a radial direction forming a bearing disc of said axial bearing.
