Attaching the Blades and Hub to Generator:
Figure 7: Diagram for attaching blades and hub to generator:
Step1: With the blades already attached, slide the hub onto the threaded portion of the
generator’s shaft as shown in Step 1 of Figure 7.
Step 2: Slide on the flat washer, followed by the lock washer, followed by the nut. Tighten the
nut to 180 lb-ft (245 N·m). Take special care not to grab or push on the blades while tightening
the nut as this could damage the blades.
Step 3: It may be difficult to get the nut to “catch” and tighten because the generator shaft
spins freely. If this is the case, a vise grip can be used to immobilize the shaft of the generator.
Cardboard can be wrapped around the generator shaft to protect it from being dented or
scratched from the vise grips as shown in Step 3 of Figure 7.
Final Assembly of the Windtura 750 Wind Turbine
The Windtura 750 Wind Turbine is now completely assembled and mounted on the
tower. Before continuing, look over the entire wind turbine to be sure everything is attached
correctly and securely. In particular, pay special attention to all fastener connections and
attachments.
