    Post Gearing Ratio Question

    How to find out the maximum gearing ratio that can be connected to a PMA 12 volt generator with dimensions. The mechanism connected to the shaft produces 111.404N of force with a time interval of 2 to 4 seconds. The displaced distance of the mechanism connected to the shaft is 0.8605meters, therefore the power produced varies from 47.93 Watts to 19.174 Watts. The gearing box needs to have a maximum diameter of 3.8cm. Could someone tell me how to find out the maximum gear ratio or guide me with how to do it, or other information I need to consider. I do not have a specific number of teeth, distance of depth I want to have between the gears. As long as I am able to maximize the gearing ratio it will be the best.

    Any guidance, answers, or anything in general will be highly appreciated.

    Thank you,

    Gear ratio will change one rpm to another or torque to another.

    You need to determine your require torque and rpm requirements.
