Abstract
A shafting arrangement for a ship comprises a tailshaft supported in bearings in a stern tube which is rigidly mounted in the ship's hull. The tailshaft has a flange which is located in a self-aligning thrust bearing secured to the stern tube. The forward end of the tailshaft is coupled to one end of a tubular intermediate shaft by a first flexible diaphragm coupling which is secured at its periphery to the intermediate shaft and coupled by its hub to the tailshaft. A second flexible diaphragm coupling is secured at its periphery to the other end of the intermediate shaft and coupled by its hub to the output shaft of the propulsion unit or main gearing.
Claims6
In a ship with a hull, a shafting arrangement comprising:
- a stern tube rigidly mounted in the ship's hull;
- bearings in the stern tube;
- a tailshaft supported in said bearings;
- a flange on said tailshaft;
- a self-aligning thrust bearing secured to the stern tube, said flange engaging said self-aligning thrust bearing for transmitting thrust from said tailshaft to said stern tube through said thrust bearing;
- first and second flexible diaphragm couplings, each coupling having a hub and a periphery;
- a tubular intermediate shaft;
- and a drive output shaft, the forward end of the tailshaft being coupled to the stern end of the tubular intermediate shaft by the first flexible diaphragm coupling and the other end of the intermediate shaft being coupled to said drive shaft by said second flexible diaphragm coupling.
