Repeat Problem 8.68 for a planet ring of 200 mm inside diameter.

Problem 8.68

In Figure 8.40b (a planetary cone transmission), let the ring gear have 45 teeth and the planets 15 teeth. If the reaction ring has an inside diameter of 5 in, what would the required cone diameters be for output speeds ranging from 450 rev/min clockwise to 180 rev/min counterclockwise, with 1800 rev/min input clockwise. Give cone diameters at points of contact for extreme positions of the reaction ring. (Note: The data for this problem do not represent actual dimensions of any commercially available transmission.)
