                                                         FIGURE 6.19 Design of a rotating
                                                         machine for sorting rollers.


           How to make the right choice of ratios? We will demonstrate on the basis of this
        specific example of a five-position machine. We denote:

              o) 3 = angular speed of pinion 3,
               ft = angular speed of lever 4,
               z 3 = number of teeth on pinion 3,
               z 6 = number of teeth on sun gear 6.

        Then we can write

               TEAM LRN                       the mechanism shown in Figure 6.19.
