摘要： A wind turbine has a bearing housing, a rolling element bearing within the bearing housing and a space within the bearing housing for containing grease for lubricating the rolling element bearing. A shaft is rotatably supported by the rolling element bearing. A pressure sensor in fluid communication with the space measures the pressure of grease in the space within the bearing housing.

摘要： The present invention relates to a coupling assembly (1) for fixedly connecting a rotational member (2) to an end section (3) of a hollow shaft (4). It may e.g. be used for connecting the main shaft (4) of a wind turbine (28) to a planet carrier (2) of a coaxial planetary gear system. The coupling assembly (1) comprises a shrink ring (6) and a coupling element (7). The shrink ring (6) has an outer diameter corresponding to the inner shaft diameter (d) and a conical surface (14) for connecting the shrink ring (6) and the coupling element (7). The coupling element (7) comprises an annular groove (18) with a groove diameter corresponding to the outer shaft diameter (D) and a conical surface (20) matching the shrink ring (6). When in use, the hollow shaft (4) is arranged in the groove (18) and connected to the coupling element (7) by axially extending bolts (9). Hereby a torque can be transferred by both the shrink connection and the bolts fastened into the hollow shaft. The coupling element (7) preferably comprises an outer flange (26) to which the rotational member (2) can be fastened.

摘要： The present invention relates to an insulated shaft joint (1) for electrically insulating a rotational member (2) from an end section of a shaft (3) to which the rotational member (2) is connected. The insulated shaft joint (1) comprises a plurality of first grooves (4) arranged in an outer surface of the end section of the shaft (3) and extending in an axial direction of the shaft (3), one or more rows of electrically insulating members (5), and an annular electrically insulating cage (6) arranged circumferentially around the plurality of first grooves (4). The insulating cage (6) comprises one or more rows of through-going openings (7), arranged circumferentially. The through-going openings (7) is being shaped and dimensioned so that they are adapted to surround and guide the insulating members (5). The rotational member (2) is arranged circumferentially around the annular electrically insulating cage (6). The rotational member (2) comprises a plurality of second grooves (8) arranged in an inner surface of the rotational member (2) and extending in an axial direction of shaft (3). The through-going openings (7) in the insulating cage (6) are arranged aligned with the plurality of first grooves (4) and the plurality of second grooves (8). The insulating members (5) are arranged in the through-going openings (7) of the insulating cage (6) and in the first and second grooves, so as to be adapted to transfer torque from the shaft to the rotational member (2) via the insulating members (5).
