GEAR MODELS - SIMPLE GEAR TRAIN | |
V. Ryan © 2003 | |
Gear model kits are very useful when learning about gears. The photographs below show a useful kit made from a soft but rigid plastic material. The parts can be put together without the use of tools and various components are supplied including a range of gear wheels. If you have the same or similar kit, set up the simple gear train shown below and attempt the exercise. |
|
|
1. Put the back
board and base in position. 2. Add the first small gear wheel and rotate it by hand. |
|
|
|
3. Add a larger
second gear wheel that meshes with the first and spin both gears to
check that they rotate. |
|
4. Add a third
gear wheel and spin all three gears to check that they mesh properly
together. |
5. Try setting up another gear train using two gears. What is the gear ratio? What direction do the gears rotate? |
