Demonstration Gear System Model
Product Code : JA-PLE-4238
The Demonstration Gear System Model (SKU JA-PLE-4238) belongs to a series of models that demonstrate different gearing systems; this one is a simple three-speed and reverse gear system using spur gears. Transparent slide plates let the class see every gear, and indexes on the primary and secondary shafts show the change in direction and relative speed of rotation. This demonstration gear box model is used in physics, automobile and mechanical engineering teaching.
Specifications
The model is a three-speed and reverse spur-gear system behind transparent slide plates, with reverse obtained by a small lay-shaft pinion between the two main shafts, gear selection by a short ball-ended lever and indexes on the primary and secondary shafts.

Applications of the demonstration gear box model
Turning the primary shaft in each gear and reading the shaft indexes lets students measure gear ratios directly, and engaging reverse shows how an idler pinion changes the direction of rotation.
- Finding gear ratios from the relative speed of the primary and secondary shafts
- Showing how an idler pinion on a lay shaft gives reverse rotation
- Explaining how a vehicle gear box gives three forward speeds and reverse
- Physics lessons on simple machines, torque and speed ratio
- Automobile and mechanical engineering classes in polytechnics and TVET institutes
