Introduction
- Collaborates with OSE Clubs - the Open Hardware Enterprise Club.
- Introduces the concept of open source product development
- This module teaches you how to design and make geardowns for various applications using 3D printing and design software.
- Outcomes:
- Learning about mechanical advantage, force, torque, speed, efficiency, and power
- Hands-on understanding of torque via Torque Measurement], rotational speed measurement (Arduino Tachometer), and Rotational Power Calculation.
- Gaining hands on experience with collaborative product development
Planetary Gears
- Why gears? Give me a lever long enough, and I shall move the world.
- Why planetary gears - compact and easily stackable form lends itself to many applications. See Curriculum - Grinder
- 3D Printer - for parts printing
- Lesson 1 - Using Wiki and Google Docs for documentation and collaboration.
- Exercise 1 - Create a Template
- Lesson 2 - theory of Planetary gears. Force, torque, speed calculations. 1 hour
- Lesson 2 Group or Individual Exercise in Google Docs - Find the torque and speed on a sample gear with 1" sun, 4" planets when driven with the Open Source Cordless Drill. Document on Google Doc Gear Calculation Spreadsheet.
- Lesson 3 - Open source planetary geardown generation in OpenSCAD
- Lesson 3 Exercise -
Guidelines
- Planetary Geardown Wiki Page - has all templates
- Exercises can be done singly or as a team.
- Singly - students can take one page each of the Template
- As a team, group of students can work on the same document - up to as many students as needed
- For teamwork, role allocation happens on first page of document with a graphical icon
- Upload pictures to your social media site for embedding
