20150048701 | Rotor Including Segmented Yoke - Rotor for motor or generator, which rotor ( | 02-19-2015 |
20140021421 | TENSIONING DEVICE - A tensioning device ( | 01-23-2014 |
20130068713 | LIFTING FRAME DEVICE - A lifting device for handling and/or moving loads, including two vertical booms which via one of their ends are pivotally connected to a base and via their opposite ends are pivotally connected to a horizontal beam, forming a frame for the lifting device wherein at least one cylinder is connected to at least one of the vertical booms so as to be able to turn the lifting device around the pivot point. The horizontal beam is further pivotally connected to at least one tension rod. The vertical booms, the tension rods and the horizontal beam will then be pivotal in relation to each other. By means of the present invention, a less torque-critical lifting device is provided, as the vertical booms, when handling and/or moving a load, will take up compressive forces, while the tension rods will take up tensile forces. | 03-21-2013 |
20130040514 | THRUSTER UNIT AND METHOD FOR INSTALLATION OF A THRUSTER UNIT - In a thruster for a vessel including a hull, the thruster comprises at least one tunnel element and at least one thruster unit. The tunnel element includes at least a part of a through tunnel in the hull when arranged in the hull. The at least one thruster unit and the at least one tunnel element include cooperating fastening devices for detachably fixing the at least one thruster unit in the at least one tunnel element such that the at least one thruster unit is configured to be passed through the tunnel and mounted to the at least one tunnel element, or demounted from the at least one tunnel element and passed out of the tunnel. A method for mounting and demounting a thruster in a tunnel element includes a tunnel element arranged in the vessel of a hull. | 02-14-2013 |
20120309242 | HYBRID PROPULSION SYSTEM FOR A VESSEL - Hybrid propulsion system for a vessel including main engines connected to propulsion to propulsion means via transmission devices and connection devices for connection and disconnection, where the system includes one or more electrical machines arranged to the transmission device(s) via connection device for connection and disconnection of the from the transmission device, and one or more hybrid shaft generators, which is/are arranged between the electrical machine and one or more switchboards for the vessel. | 12-06-2012 |
20120122356 | Support of propeller unit for a vessel - The present invention relates to a rim driven propeller unit for a vessel, where a number of permanent magnets ( | 05-17-2012 |
20110241453 | ELECTRICAL MACHINE AND METHOD FOR THE MANUFACTURE OF STATOR SECTIONS THEREFOR - Electrical machine with a rotor with magnets carried by an annular carrier, in which a magnetic field is created over an air gap between two rotor parts, at which an ironless stator with windings is arranged. A space saving machine is achieved with a stator which is assembled of sections with channels for circulation of coolant, and which has windings with an annular, compact central part providing the active part of the stator. A method for manufacturing stator sections for such electrical machines is described, where a winding is embedded in an electrically insulating casting material for providing a rigid element. A coil is arranged in one part of a bisected shell housing or a bisected casting mold, and the shell housing or mould is closed, casting material is introduced through an opening and the inner part of the housing or mould is subject to underpressure and possibly vibration. | 10-06-2011 |
20100288176 | Method and Apparatus for Attaching a Ship Rudder for Rudder Shaft, a Rudder Shaft, and a Shiprudder - The present invention concerns an apparatus and method for attaching a ship rudder to a rudder shaft. The rudder shaft includes a cylindrical portion and an expanded flange part with a cylindrical portion, followed by a conical portion. The rudder includes a rudder element and a flange element for attachment to the rudder element. The flange element includes an internally cylindrical portion for mating, sliding and sealingly surrounding the cylindrical portion of the rudder shaft and an internally cylindrical portion for sliding, mating arrangement around the cylindrical portion of the flange part of the rudder shaft. The rudder element also includes a conical opening for mating attachment to the conical portion of the conical portion of the rudder shaft. It is provided channels for applying hydraulic pressure between the expanded flange part of the flange element, and means for tightening the flange element to the rudder element. Furthermore the invention comprises a rudder shaft for a ship rudder, a ship rudder with a conical opening, and a method for disassembly of a ship rudder from a rudder shaft. | 11-18-2010 |
