Abstract: A method of assembling or disassembling a gear assembly (20) of a wind turbine (10), the gear assembly (20) comprising a first helical gear (28) and a second helical gear (24) configured for rotatable engagement with the first helical gear (28), the method comprising transmitting a control signal to cause: axial movement of the first helical gear (28) at an axial speed relative to the second helical gear (24) along a rotational axis of the first helical gear (28): and, rotational movement of the first helical gear (28) at a first rotation speed relative to the second helical gear (24) about the rotational axis of the first helical gear (28), wherein one of the axial speed and the first rotation speed is a predetermined speed, and the other of the axial speed and first rotation speed is determined in dependence on the predetermined speed, and wherein the control signal causes the axial and rotational movement of the first helical gear (28) to occur simultaneously to engage or disengage the first and second helical gears (28, 24).

Abstract: 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).
