BUSHINGS
7.2.1 Bushing Basics
A bushing is the piece of equipment that
anchors the Superwind yaw shaft to the
mast, allowing it to freely rotate 360º on
its vertical axis. The bushing slides over
the yaw shaft of the turbine, where it is
then fastened in place utilizing three
screws. Once attached to the yaw shaft,
the bushing is then inserted into the mast
tube and screwed in place for support,
stability and safety (Fig. No. 7.2.1).
The original bushing used with the
Superwind 350 turbine was designed to
help with noise reduction when installed
aboard sailing yachts. The concept and
design of these bushings has evolved
considerably since then.
7.2.2 Bushings Types
There are currently three types of bushings available for use with the Superwind
350/48V allowing installations that can accommodate a wide variety of mast
configurations These are the American Delrin® (White), the American Stainless Steel,
and the American Delrin® (Black) bushings (Fig. 7.2.2a, 7.2.2b and 7.2.2c). Bushing
selection depends on the type of location the turbine will be deployed in.
American Delrin® bushings are used for integration on ships and other salt water
applications. The optional American Stainless Steel bushing is used on tall towers and
in locations subject to higher wind speeds, as well as mobile platforms (such as
trailers).
