10. The figure below illustrates the gears in a speed-change gearbox used in machine tool applications. By sliding the cluster gears on shafts B and C, nine speed changes can be obtained. The problem of the machine tool designer is to select tooth numbers for the various gears so as to produce a reasonable distribution of speeds for the output shaft. The smallest and largest gears are gears 2 and 9, respectively. Using 20 teeth and 45teeth for these gears, determine a set of suitable tooth numbers for the remaining gears. What are the corresponding speeds of the output shaft? 450 rev/min Input 7 8
