GL 100 Gear Trains Apparatus Show data sheet (pdf file) Print page
Technical Description

This apparatus is used to demonstrate belt drives, wheel and disk drives, and gear trains. Basic terminology and relationships, e.g. the transmission ratio, direction of rotation reversal, reference circle and modulus, the function of intermediate gears, and so on can be clearly demonstrated. A solid frame made of anodised aluminium section forms the base for the unit. The bearings for the pulleys and gears are attached to the T-slots in the profile using clamping levers. These are easy to release and can be slid horizontally making a wide range of different set-ups possible. All experiments are carried out using manual power. The size of the unit ensures that the experiment is clearly visible even for larger groups of students.


Learning Objectives / Experiments

- Function and differences between belt drives, wheel and disc drives,

  and gear trains
- Explanation and demonstration of
  + transmission
  + reference circle
  + modulus
  + function of intermediate gears



* Sturdy benchtop unit, ideally suited to

  demonstrations due to its size
