Learn MoreLet's say your largest acceptable ring gear has 100 teeth, and your largest acceptable planet has 45 teeth, your largest possible reduction (assuming all your gears are of the same module - using different modules in the two stages, one can attain higher gear ratios ) will be 1/[1-(44*100)/(45*99)] = 81 to 1.

Learn MoreDivide the number of teeth on each "driven" gear by the number of teeth on the "drive" gear for each interlocking set of gears to calculate the intermediate gear ratios . In our example, the intermediate gear ratios are 20/7 = 2.9 and 30/20 = 1.5. Note that neither of these are equal to the gear > ratio for the entire train, 4.3.

Learn More6/13 · We can calculate ratio transmission by formula: i = -A/C -> reduce speed system. If ring gear is input power -> Output is sun gear. : i = -C/A -> increase speed system. + We will fix sun gear, planet gear can rotate around their axis. If carrier is input power -> Output is ring gear. i
