[[_TOC_]] # Overview In this chapter we will focus on how to put all parts together. We also call it the wedding - a polyamouros one you can say. Nacelle, Alternator, Rotor and the Wind Vane are mounted together. Ét voila, the _windkit_ is ready to produce energy. We'll start with the Nacelle and the Alternator Stator. # Assembly ## 1. Nacelle - Alt.Stator ### Place the Alternator Stator front facing down ![MainAssembly.windkit_1](img/MainAssembly/MainAssembly.windkit_1.png) ### Place Bolts underneath 4x M12x60-Screw without washers ![MainAssembly.windkit_2](img/MainAssembly/MainAssembly.windkit_2.png) ### Place first Housing Bearing Mounting side up 1x UCF205 ![MainAssembly.windkit_3](img/MainAssembly/MainAssembly.windkit_3.png) ### Take care of the grease nipple ![MainAssembly.windkit_4](img/MainAssembly/MainAssembly.windkit_4.png) ### Place Nacelle ![MainAssembly.windkit_5](img/MainAssembly/MainAssembly.windkit_5.png) ### Place second Housing Bearing 1xUCF205 Mounting side down ![MainAssembly.windkit_6](img/MainAssembly/MainAssembly.windkit_6.png) ### Tighten slightly the Nuts 4x M12-Washer 4x M12-Nut ![MainAssembly.windkit_7](img/MainAssembly/MainAssembly.windkit_7.png) ![MainAssembly.windkit_8](img/MainAssembly/MainAssembly.windkit_8.png) ## 2. Shaft Place the Nacelle on a piece of 2" pipe for the next steps. ### Place the Shaft ![MainAssembly.windkit_9](img/MainAssembly/MainAssembly.windkit_9.png) ### Tigthen the nuts ![MainAssembly.windkit_11](img/MainAssembly/MainAssembly.windkit_11.png) ### Tigthen the setscews of bearing There are 2 setscrews per bearing, tighten them one after the other. ![MainAssembly.windkit_10](img/MainAssembly/MainAssembly.windkit_10_marked.png) ## 3. Alternator Rotor We start by preparing and mounting the painted Upwind Magnet Disk. ### Place the Taper Bush Hub ![SubAssembly.AlternatorRotor_16](/img/AlternatorRotor/SubAssembly.AlternatorRotor_16.png) ### Mount on the Taper Bush Hub 6 x M6x25-Screw 6 x M6x25-Washer 6 x M6x25-Nut ![SubAssembly.AlternatorRotor_18](/img/AlternatorRotor/SubAssembly.AlternatorRotor_18.png) ### Place the Taper Bush ![SubAssembly.AlternatorRotor_21](/img/AlternatorRotor/SubAssembly.AlternatorRotor_21.png) ### Loosly tighten the Taper Bush Set Screw ![SubAssembly.AlternatorRotor_22](/img/AlternatorRotor/SubAssembly.AlternatorRotor_22.png) ### Place the Upwind Magnet Disk onto the Shaft ![MainAssembly.windkit_12](img/MainAssembly/MainAssembly.windkit_12.png) ### Tighten the Taper Bush Setscrews ![MainAssembly.windkit_13](img/MainAssembly/MainAssembly.windkit_13.png) ### Add the Disk Fasteners To do this, turn the assembly upside down and insert the screws from underneath. 9x M6x85-Screw Stainless Steel Place a few pieces of wood underneath to hold the screws in place. ![MainAssembly.windkit_14](img/MainAssembly/MainAssembly.windkit_14.png) ### Add the Spacer Sleeves 9x Stainless steel sleeves 8x6x1 mm (up to M6), 50mm Length ![MainAssembly.windkit_16](img/MainAssembly/MainAssembly.windkit_16.png) ### Add Downwind Magnet Disk Important: Place some wood pices between the stator and the rotor to prevent damage due to the strong magnetic forces! ![MainAssembly.windkit_17](img/MainAssembly/MainAssembly.windkit_17.png) ### Tighten the Alternator Stator 9x M6-Washer 9x M6-Nut ![MainAssembly.windkit_18](img/MainAssembly/MainAssembly.windkit_18.png) ![MainAssembly.windkit_19](img/MainAssembly/MainAssembly.windkit_19.png) ### Measure the airgap Measure the airgap -> if too large, disassemble and take out washers, add shim washers (DIN 988) to adjust -> iterate ![MainAssembly.windkit_21](img/MainAssembly/MainAssembly.windkit_21.png) ### Alternator is ready to be used ![MainAssembly.windkit_20](img/MainAssembly/MainAssembly.windkit_20.png) ## 4. Rotor ### Place the first Rotor Blade Also place the Rotor Front Mounting Plate ![MainAssembly.windkit_22](img/MainAssembly/MainAssembly.windkit_22.png) ![MainAssembly.windkit_23](img/MainAssembly/MainAssembly.windkit_23.png) ### Attach the Rotor Blade with the Rotor Blade Fasteners ![MainAssembly.windkit_24](img/MainAssembly/MainAssembly.windkit_24.png) ![MainAssembly.windkit_25](img/MainAssembly/MainAssembly.windkit_25.png) ![MainAssembly.windkit_26](img/MainAssembly/MainAssembly.windkit_26.png) The inner screw will have a special nut, the Rotor Blade Fastener Slot Nut. The slot nut is placed in the rectangular hole. ![MainAssembly.windkit_27](img/MainAssembly/MainAssembly.windkit_27.png) ![MainAssembly.windkit_28](img/MainAssembly/MainAssembly.windkit_28.png) ### All Rotor Blades assembled Repeat the last steps with the two other blades ![MainAssembly.windkit_29](img/MainAssembly/MainAssembly.windkit_29.png) ### Measure and center the blades Measure and write down the distance of one tip of the blade to another. After the first measurement, adjust the blades by unscrewing the outer blade fasteners, move the blade and re-tighten the fasteners. Repeat this process until you have a satisfying result of all three blade tips beeing at a distance of plus minus 2 mm to each other. ![MainAssembly.windkit_30](img/MainAssembly/MainAssembly.windkit_30.png) ## 5. Windvane ### Place the Vane Pipe ![MainAssembly.windkit_31](img/MainAssembly/MainAssembly.windkit_31.png) ### Attach the Vane Pipe with the U Bolt Clamp ![MainAssembly.windkit_32](img/MainAssembly/MainAssembly.windkit_32.png) ![MainAssembly.windkit_33](img/MainAssembly/MainAssembly.windkit_33.png) ![MainAssembly.windkit_34](img/MainAssembly/MainAssembly.windkit_34.png) ### Attach Vane Mounting Place the Vane Mounting upright and attach it to the U Bolt Clamps ![MainAssembly.windkit_35](img/MainAssembly/MainAssembly.windkit_35.png) ![MainAssembly.windkit_36](img/MainAssembly/MainAssembly.windkit_36.png) ### Place and Mount the Vane Use the Vane Fastener to attach the Vane ![MainAssembly.windkit_37](img/MainAssembly/MainAssembly.windkit_37.png) ![MainAssembly.windkit_38](img/MainAssembly/MainAssembly.windkit_38.png) ## Cable ### Attach the Cable Gland ![MainAssembly.windkit_39](img/MainAssembly/MainAssembly.windkit_39.png) ### Install the Cable Install the cable with the generator plug trough the tower and the cable gland. Connect the plug to the generator. Tighten the cable gland.
