For the information assigned below, design a gear train with the pitch, pressure angle, and reduction indicated. The input and output gears should rotate in the direction indicated. Use the "Commercially available, Stock Gears" sheet to identify gears with appropriate N values. The gear train should be free of undercut gears. Make a sketch (yes, use a ruler) of the gear train at a convenient scale. Put an emphasis on using the fewest gears possible and on using gears with the fewest teeth. This problem will require multiple steps. Attempt to design a 2-stage gear train. If unsuccessful after 2 iterations, proceed to a 3-stage gear train. Pa = 12; p = 20; reduction = 180:1; input/output rotate in the same direction No undercut gears Direct Mesh 1-Stage Gear Train 2-Stage Gear Train 3-Stage Gear Train
