Description

Thanks to rosch8 for the really great original wind turbine.

After the original wind turbine had been running without any problems for some time, I wanted to make it bigger. Increased the hub, rotor blade and spinner to 150% and changed the bearing seats and screw mount. The rotor diameter is now about 620 mm. A stainless steel threaded rod is attached to the fuselage with two nuts, I secured the nuts with two-component glue. The rotor is mounted with two ball bearings 608 ZZ. rosch8 has created the rotor blade geometry very well, which allows the rotor to reach impressive speeds. The rotor blades are available in four versions, No-Normal, Wl-Winglet, Br-Braking Wing, 225x225 fits on print bed 225x225 mm. Seven different tail units can be mounted.

The outer rings of the bearings rest against the hexagonal surfaces of the rotor blades, smooth these surfaces and measure the dimension. Scale Distance23 in the cutting program to the same length or slightly larger. The bearings must still be able to be moved by hand in the hub and in the spinner. Glue the three nuts into the hub before assembly. When assembling, I recommend countering with two nuts instead of the M8 self-locking nut shown.

The vertical axis is inserted into the bottom of the fuselage, the 8 mm inner diameter must be able to rotate easily on the 8 mm rod. To do this, adjust the vertical axis with a test print with "Horizontal expansion" and "Horizontal hole expansion", or work with an 8.2 mm drill. Glue the round rod tip in the vertical axis with a drop of glue for easy swiveling as shown in the picture. The 8 mm rod must sit tight in the vertical holder, the VertikalHalter16x8 fits on a 16 mm rod / tube and VertikalHalter0Z5x8 fits a 1/2" water pipe.

Are needed:

2x ball bearings 608 ZZ for the rotor

3x cylinder screw M5x30 with nut for rotor

1x threaded rod M8x120 for rotor

4x nut M8 for threaded rod

1x cylinder screw M4x20 with nut for the rear

2x cylinder screw M4x12 with nut for tail unit

1x stainless steel or brass rod 8x100 for vertical axis

1x stainless steel or brass rod 8x12 with tip for vertical axis

I printed all the wind turbines with PLA. I recommend brighter PLA up to 35°C air temperature. If it is warmer or if darker filament should be used, then use PETG or better ASA.

I would be happy about a make or remix.
