Figure P9-4a shows a reverted clock train. Design it using 25° nominal pressure angle gears of 24 Pd having between 12 and 150 teeth. Determine the tooth numbers and nominal center distance. If the center distance has a manufacturing tolerance of ± 0.006 in, what will the pressure angle and backlash at the minute hand be at each extreme of the tolerance?
