Funny Gears lets you play with spur gears in 2D and explore the basic requirement of gearing. You can form and construct your own gears and explore what a mating gear would look like. As the Gears are described by spline curves with a B-Spline basis, the program may also be intereseting for someone who wants to explore the B-Spline representation.

• Create and manipulate spline curves
• Create your own tooth of a gear and construct a gear of it
• The program can construct a mating gear to your given one on basis of the basic requirement of a gear tooth system
• The used construction can be visualized and different colores make it easy to understand the relationship
• Set the gears in action and let them rotate to analyse the contact region
• Find out how the two gears interact:
  • detect problematic points (which do not fulfill the basic requirement of a gear tooth system)
  • analyse the path of contact
  • understand the contact ratio by the visualized coverage of the contact
• Try to improve the gearing by
  • changing the form of a tooth of your driving gear
  • changing the number of teeth of your driving gear
  • changing the number of teeth of the driven gear
• and investigate how the mating gear reacts on these changes
