Claim 0:
1. A turner gear arrangement for turning a rotor of a wind turbine via a drivetrain thereof;
said turner gear arrangement comprising a motor, a torque transmission assembly, and a mounting assembly;
said torque transmission assembly comprising one or more rotational elements and including a turner output drive rotatable about an axis, said turner output drive being operably coupled to and driven by said motor and configured to transmit rotational motion to a gearbox output shaft of said drivetrain, said turner output drive further including an output guide portion;
said mounting assembly being configured to mount said motor and said transmission assembly in a fixed relation with respect to said wind turbine drivetrain;
and
wherein said mounting assembly further includes a radial support interface which operably engages with said output guide portion, to constrain movement of said turner output drive in a direction transverse to a rotational axis of said turner drive;
wherein said turner gear arrangement includes a mounting bracket fixable to a drivetrain housing; and
wherein said mounting bracket fastens said motor that is operatively coupled to the turner output drive.
