NOTE: The following applies to all mast and support structures:
Before assembling the wind generator, ensure there are no fittings, stays, etc, in the
area from the top of the mast top to a point 650 mm below the mast top. This
clearance is crucial, because as the rotor controller pitches the blades at high wind
velocities, the distance between the blades and the mast will be reduced.
7.3.1 Mounting on a 60.3mm or 60.0mm mast tube
The yaw shaft of your Superwind 350/48V fits multiple sizes of mast tubes:
Mounting on a mast tube 60.0 mm or 60.3 mm
Chart No. 7.3.1.
7.3.1.1 Preparations at the mast head:
Deburr the end of the tube carefully (inside and outside).
File off the welding seam if necessary.
With welded tubes, ensure the welding seam does not prevent insertion of the
yaw shaft. Smooth the seam with a round file or similar tool if necessary.
The included bushing (Delrin
®
White or Black) has to be mounted onto the
yaw shaft of the generator unit. Before installing the plastic bushing onto the
yaw shaft, align the three 16 mm OD holes of the bushing with the respective
threaded M6 holes of the yaw shaft. Then gently push the plastic bushing onto
the yaw shaft (with the collar facing the turbine) until reaching the stop limit
stop at the O-ring seal. In the case of the American Delrin
®
(White) bushing,
take care not to damage the damping rings during installation.
Next, insert the three rubber gasketed M6 x 8 socket cap bolts into each of
the holes and tighten until the heads are tight against the yaw shaft (Fig.
7.3.1.1a). Once installed correctly, the screw heads will be flush with the OD
of the bushing and will not interfere with insertion into the mast tube.
