Creating a Gear Box
Inventor® and Inventor® Professional mechanical design and 3D CAD software includes: freeform, direct, and parametric modeling options; design automation tools; and advanced simulation and visualization tools.
During this activity, students will review the Inventor Software and the basic modeling functions and extrusions to create a holiday ornament that represents a gear box mechanism we have learned about.
AutoDesk allows students to download the software for free from the site below.
STEM-EC 7 - Summarize and apply engineering solutions through the audience appropriate application of engineering graphics and technical writing.

Saving your files:
- Create a holiday ornament, key chain, or bag tag using AutoDesk Inventor.
- Gear Box Criteria:
- Your object should be no larger than 1.5x1.5x1.5 inches cubed - for the mechanism gear box part.
- You gear box should be 1/8" thick (.125).
- You should only have 2 sides and a top for the gear box.
- Axle width - my suggestion is .125" - don't make the hole for the axle the exact same size.
- You must have at least 1 mechanical part that moves using one of ideas from the mechanism boxes we have been creating.
- Think about how your pieces will print and assemble to make sure you won't have assembly directions.
- For example - how will the axle with cam pieces go into your gear box?
- You may need to use super glue on a couple of pieces.
Saving your files:
- Each piece of your mechanism should be drawn as a separate part file in inventor.
- Once you have all of your inventor parts, you should complete an assembly drawing to ensure they fit together correctly.
- Save all the parts in your X drive as .stl files.
- This will be a completion grade based on how well you met the criteria.
- Does the gear box function?
- How well do the mechanisms fit together?
