GEAR MODELS - RACK AND PINION MODEL | |
V. Ryan © 2003 | |
Rack and pinion gear systems involve the use of a round gear called a pinion and a flat gear called a rack. A simple model of this type of gear system is shown below. Using the same or similar gear modelling kit, set up the arrangement of gears shown in the photographs. |
|
|
1. Put the back
board and base in position. |
|
|
|
3. Add the ‘gauge’ above the pinion. This will be used later to measure how far the gear moves. Check the pinion can still rotate. |
|
4. Add the ‘rack’
(flat gear) so that it meshes with the pinion. Check the pinion can
still rotate. |
|
|
5. Explain one use of a rack and pinion gear system. Draw a diagram to help explain your answer. (click here for example) |
