A method for refurbishing a wind turbine 10 includes removing an existing machine head 120 from the wind turbine 10, and providing a new machine head 220 and an adapter 250. The new machine head 220 includes a base frame 222, and further includes a plurality of fastener holes 224 defined in the base frame 222. The adapter 250 includes an outer sidewall 252 and defines a first plurality of fastener holes 254 and a second plurality of fastener holes 256, the first plurality of fastener holes 254 disposed in a first hole pattern 255, the second plurality of fastener holes 256 disposed in a second hole pattern 257 different from the first hole pattern 255. The method further includes connecting the new machine head 220 and the adapter 250 such that the adapter 250 is connected to and between a yaw bearing 134, 234 and one of the base frame 222 or a top flange 112 of a tower 110 of the wind turbine 10.

It is described a bearing system (200) for a wind turbine with a generator with an outer rotor, preferably for a generator with an outer rotor for a rotor housing of a wind turbine, the bearing system (200) comprising: An inner bearing ring (210), an outer bearing ring (230), a first electrical insulation element (220), a second electrical insulation element (240), a plurality of roller elements (250), a first metal element (261) and a second metal element (262). Therein, the roller elements (250) are arranged at an inner volume between the inner bearing ring (210) and outer bearing ring (230). The first electrical insulation element (220) comprises the first metal element (261). The second electrical insulation element (240) comprises the second metal element (262). The first electrical insulation element (220) is arranged at least partially around the inner bearing ring (210) in order to provide an electrical shielding to the inner of the bearing system (200). And the second electrical insulation element (240) is arranged at least partially around the outer bearing ring (230) in order to provide an electrical shielding to the inner of the bearing system (200).

Die Erfindung betrifft eine Sensoreinrichtung (1) mit einem dünnen, bandartigen Trägermaterial (2,20) und mit einem oder mehreren Kraftsensoren (3), die auf das Trägermaterial aufgebracht und/oder in das Trägermaterial integriert sind, wobei das Trägermaterial dazu eingerichtet ist, a) zwischen einer Außenfläche (5,6,21) eines Wälzlagers (4) und einer als Gegenlager wirkenden Aufnahmeeinrichtung (7) für das Wälzlager angeordnet zu werden und mittels der Kraftsensoren eine oder mehrere der zwischen dem Wälzlager und dem Gegenlager wirkenden Kräfte zu erfassen und als elektrische Signale abzugeben, oder b) zwischen einer Außenfläche eines Wälzlagers und einer mittels des Wälzlagers gelagerten drehbaren Welle angeordnet zu werden und mittels der Kraftsensoren eine oder mehrere der zwischen dem Wälzlager und der drehbaren Welle wirkenden Kräfte zu erfassen und als elektrische Signale abzugeben. Die Erfindung betrifft ferner ein Verfahren zur Auswertung von Signalen einer Sensoreinrichtung mit mehreren über den Umfang eines Wälzlagers verteilt angeordneten Kraftsensoren.
摘要:
The invention relates to a bearing assembly (1) for a support roller (2) which is at least sectionally designed in a hollow-cylindrical manner, comprising at least one bearing (3) that supports the support roller (2), wherein a carrier element (5) is directly or indirectly arranged between a ring (4) of the bearing (3) and the support roller (2). In order to enable problem-free support of the support roller by the bearing, even when minor malalignments exist between the bearing and support roller, according to the invention the carrier element (5) comprises two hollow-cylindrical sections (5', 5'') which extend in the axial direction (a) of the support roller (2) or the bearing (3) and are connected to a ring-shaped section (5' '') extending in the radial direction (r).
摘要:
A fan motor is disclosed. The fan motor includes a rotating shaft (150), a motor unit, a bearing (151), a bearing housing (152), a preload applying device (167, 165), and a bush (160). The preload applying device is disposed between one axial end of the bearing (151) and the bearing housing (152), and applies force to the one axial end of the bearing (151) in an axial direction by using elastic force. The bush (160) is coupled to an outer circumferential surface of the bearing (151) and slidably mounted on an inner circumferential surface of the bearing housing (152) in an axial direction. A protrusion (161) is formed on one axial end portion of the bush (160), and a protrusion accommodating groove (162) is formed on an axial inner surface of the bearing housing (152). Accordingly, the preload applying device can continuously apply an appropriate preload to the bearing (151), while the bush (160) can suppress slipping of an outer ring (1511) of the bearing (151).
