The invention relates to a transmission (4, 40, 50, 50') of a wind power plant having an auxiliary drive (6) for the rotation of a rotor shaft (3) of the wind power plant, at least one reduction stage having at least two rotary transmission bodies (12, 12', 41; 51, 52, 52', 55, 56; 86) as well as a coupling device (20, 60, 70) which is designed for coupling and for uncoupling a rotary drive body (14, 14') which can be driven by the auxiliary drive (6) to or from a rotary drive body (12, 12', 41; 51, 52, 52', 55, 56; 86), which is connected directly or via one or more reduction stages or rotary drive bodies (12, 12', 41; 51, 52, 52', 55, 56; 86) to the rotor shaft (3), wherein the coupling device (20, 60, 70) is designed to move the rotary drive body (14, 14') for coupling and for uncoupling relative to the rotary drive body (12, 12', 41; 51, 52, 52', 55, 56; 86). The invention further relates to a wind power plant and to a method for the rotation of a rotor shaft (3) of a wind power plant. The transmission (4, 40, 50, 50') according to the invention is characterized in that the movement of the rotary drive body (14, 14') relative to the rotary drive body (12, 12', 41; 51, 52, 52', 55, 56; 86) has a radial movement component transverse to the rotation axis (26 - 26"') of the rotary drive body (14, 14') and/or to the rotation axis of the rotary drive body (12, 12', 41; 51, 52, 52', 55, 56; 86). |
