Question

Examine the gear drive system shown below.  All the gears have a DP = 12.  The smallest gear is the primary driver gear and has 15 Teeth, RPM = 3600, and Torque = 2.2 N-m.  That small gear meshes with a 72-tooth gear which is connected to another gear that has 20 teeth.  That 20-tooth gear connects to the final driven gear that has 64 teeth.

    1. What is the TOTAL Gear Ratio for this system?
    2. What is the TOTAL Speed Ratio for this system?
    3. What is the Center to Center spacing of the first gear set?
    4. What is the Center to Center spacing of the second gear set?
    5. What is the final output RPM of the 64-tooth gear?
    6. What is the final output Torque supplied by the 64 tooth gear?
