Altering speed with Reuleaux polygon 1b

It is built based on the fact that while the n-sided Reuleax polygon makes 1 rev. in an ambient polygon, its center traces a loop n times. See: http://www.youtube.com/watch?v=BnvT45CjD-E Transformation ratio is 3 (= n, number of Reuleax polygon sides). Two shafts are coaxial and rotate in different directions. Velocity of the output shaft is inconstant. Theoretically, by increasing number of sides of a Reuleax polygon (7, 9, 11 …) it is possible to get large transformation ratio and make the output v
