KIDWIND GEAR SET WITH SPOOL
Experiment with gear ratios on your wind turbine or other small projects. Adding gears to your turbine can greatly increase the generator RPM giving you higher power output. The small 8-tooth gear will fit on 2mm driveshafts that are found on lots of DC generators. The gears have a keying feature that allows them to be changed quickly and easily using the included hex locks. The hex lock secures to the 9/64 inch hex-driveshaft.

Gear sizes: 64 teeth, 32 teeth, 16 teeth, 8 teeth.

With this kit you can:
• Increase generator RPM through the mechanical advantage of gear ratio.
• Increase the power output of student wind turbines.

Concepts:
• Exploring energy transformations
• Understanding ratios
• Learning about mechanical advantage
• Understanding simple machines
• Exploring the relationship between energy and forces
• Understanding forces and motion
• Developing and using physical models
• Optimising designs
