Altering speed with Reuleaux polygon 2

The mechanism is built based on the fact that while the n-sided Reuleaux polygon makes 1 rev in an ambient polygon, its center traces a loop n times. See: http://www.youtube.com/watch?v=oe8e-N3VusI Transformation ratio is 5 (= n, number of Reuleaux polygon sides) Velocity of the output shaft is very inconstant. Theoretically, by increasing number of sides of a Reuleaux polygon (7, 9, 11 ...) it is possible to get large transformation ratio and make the velocity less inconstant.
