|20110130243||PLANETARY GEAR UNIT - A planetary gear unit includes a planet carrier having a backplate and being provided with planet shafts distributed uniformly around the planet carrier's axis and extending through bores in the backplate, each planet shaft rotatably supporting a pair of planet gears by planet bearings, the planet gears being mounted between a ring gear and a sun gear for mutual interaction. The planetary gear unit further includes a key provided in a keyway of the planet shaft and extending to the backplate for preventing the at least one planet shaft from rotating around its own axis. The key and keyway are provided at a location positioned between 45° and 270° in a clockwise direction around the circumference of the planet shaft, with 0° being defined as a point at the planet shaft circumference corresponding with the largest distance from the centre of the bogie plate seen from the rotor side onwards.||06-02-2011|

|20100329868||PLANETARY GEAR TRANSMISSION UNIT WITH PLANET SHAFT LOCKING MECHANISM - A planetary gear transmission unit includes a planet carrier which supports and locates circumferentially spaced pairs of planet gears, and at least one planet shaft. The planetary gear transmission unit further includes a planet shaft locking mechanism between the at least one planet shaft and the planet carrier for preventing the at least one planet shaft from rotating around its own axis, the planet shaft locking mechanism being provided between an axial end face of the planet shaft and the planet carrier in a direction substantially parallel to the planet shaft. An advantage of the planetary gear transmission unit is that rotation of the planet shaft relative to its axis in the planet carrier is prevented. The unit results in a free of wear contact between planet shaft and planet carrier, thereby allowing all degrees of freedom of the planet shaft without disturbing the load distribution between the planet gears of a pair on one planet shaft.||12-30-2010|

|20100210407||PLANET CARRIER OF THE CAGE TYPE - Planet carrier of an epicyclic gear system with planetary shafts which are connected fixedly to the planet carrier onto which planet wheels are mounted rotatably using planetary bearings, the teeth of the planetary wheels being helical or chevron teeth, the planet carrier being of a cage type, and where at least two separate planetary wheels are placed on each planetary shaft, each wheel of which being supported by at least one double-row cylindrical bearing, where the outer bearing ring of each double-row cylindrical bearing is integrated into the planetary wheel concerned.||08-19-2010|
|20100002977||SUPPORTING RING FOR MOUNTING A BEARING OR BEARING PARTS IN A GEAR UNIT - A supporting ring for mounting a bearing or bearing parts in a gear unit, characterized in that it is relatively stiff in a radial direction, but relatively flexible in the axial direction.||01-07-2010|
|20090186740||GEAR UNIT FOR A WIND TURBINE - A gear unit for a wind turbine having an input shaft connected to the rotor hub of the wind turbine and an output shaft for connection to an electrical power generator, characterized in that the gear unit is provided with a hollow tube which is concentric with the main rotation axis and which extends through the gear unit from the input shaft to the output shaft, whereby this hollow tube provides a sealing for the gear unit in storage and transport.||07-23-2009|
|20090170655||PLANET CARRIER OF A PLANETARY STAGE WITH A BOGIE PLATE - A planet carrier of a planetary stage, the planet carrier having a bogie plate, both sides of which planet wheels can be mounted, characterized in that the planet carrier with its bogie plate is made as one monolithic piece.||07-02-2009|
|20090163316||PLANETARY TYPE GEAR UNIT COMPRISING A PLANET CARRIER WITH A PLANET BOGIE PLATE - A planetary type gear unit comprising a planet carrier with a planet bogie plate and at least one planet shaft, whereby on both sides of the bogie plate a planet wheel is mounted on the planet shaft by taper roller bearings, whereby the planet shaft is provided with an axially displaceable piece on each of its extremities forming an abutment which provides an axial support for the inner bearing rings of the taper roller bearings and with a tensioning elements by which the axially displaceable pieces can be displaced to one another for controlling the pre-tensioning on the taper roller bearings.||06-25-2009|
|20090149293||WIND TURBINE DRIVE - Wind turbine drive which is formed of a rotor with a rotor shaft and of a transmission box with a planetary gear unit which is connected to the rotor shaft, which drive is of the type whereby the transmission box is supported by the far end of the rotor shaft and is provided with a reaction arm, whereby the rotor shaft is bearing-mounted with at least one bearing which is directly fixed to the nacelle and a second bearing which is either fixed to the nacelle or which is part of the transmission box, whereby the planet carrier of the planetary gear unit is bearing-mounted in the gearbox via one bearing at the most.||06-11-2009|
