.STL File / 3D model: WIND CAR - DEFY THE WIND

Defy the wind with this small wind powered auto! Take an opposing force and use it is energy to go against it. This miniature auto demo you could pick the winds energy and transform it into movement right against that very wind. :)

  • Challenge Goals
    Use the power of the wind
    Engineering connections
    Energy transport
    Movable assemblies

  • Force Break Down

    1. The wind cups use cone shape and their substantial relative surface area to reap the wind as a force preventing counterclockwise rotation, creating clockwise rotation and performing into the cup.
    2. The wind cup shafts transfer the force to the top fitting. Their long relative duration translates to higher torque and creates a bigger second.
    3. The top fitting right transfers this torque to the very first vertical shaft and "little gear".
    4. The "little gear" and "big equipment" work jointly reversing the direction of spinning and they gear down which raises torque farther.
    5. The "big gear" rotating shaft brings the torque to the transport gears which rotate the axis of rotation 90 degrees to the axle.
    6. Eventually the axle sends the torque to the wheels bringing the winds energy to the ground causing motion.
  • Revisions & Challenges
    All of the tools were examined and revised (3) or more times to make sure solid and smooth connections. The wind cups were revised to cone shaped and grown in diameter for better wind operation from annular.

  • Theory Introduction
    This version is an excellent example for engineering connections and energy transport. One potential duty could include requiring students to estimate how many times the wind cups will rotate when a given space goes. This is computed after measuring the gear and wheel diameters.

Directions

I'll be constantly revising the design and uploading revised STL models to make this model run and simpler to build. Atm I Had say it needs a reasonable degree of model construction ability to build.

  • Parts Needed
    (4) Wind Cups
    (4) Top Rotating Shafts
    (1) Top Fitting
    (2) Perpendicular Gear Shafts
    (1) Little Gear
    (1) Big Gear
    (2) Transport Gears
    (2) Axles
    (2) Sides
    (1) Top
    (1) Underside
    (4) Spacer Bands
    (#) Little Spacer Bands
    (#) Wheel Spacer Bands
    as needed = #
    Adhesive - I.E. - Epoxy, superglue, ect
    Sandpaper/Rotary Tool (urged)

  • Printing
    All of the parts are made to print without supports. The rotating shafts have a small level advantage along the span so they may be readily printed on such an side. This manner the rotating shafts print very fast and are extremely powerful.

  • Building
    There's no mandatory order of building and also the components places are shown in the images so I'll leave that touch of liberty up to you, but I do have some ideas and certainly will share my expertise. Since almost all of them fit, I just needed to use adhesive on several sections. I am certain super glue would work also and be a lot faster, although I favor two component epoxy. I used adhesive on the top, bottom, and sides to assemble the automobile body. Additionally, I used adhesive to attach the top spacer bands to the top fitting and to the perpendicular gear shafts. You may need to ensure all the rotating parts go easily as you advance if they don't sand down the component until it rotates easily with all the construct. Eventually the transport gear spacing held and might be fixed utilizing the tiny spacer bands to stop them from binding. To restrict the axle or axle motion wheel spacer bands might be utilized itself can be shortened for a tighter allowance.
