How to Calculate 2 Stage Planetary Gear Ratio and How to Choose the Best Planetary Gears

How to Calculate 2 Stage Planetary Gear Ratio

The calculation of a two-stage planetary gear ratio involves a two-step process. Firstly, the gear ratio for each stage is calculated separately. Then, these individual ratios are multiplied together to get the total gear ratio. This process involves the following formula: Gear Ratio = (Sun Gear Teeth + Ring Gear Teeth) / Sun Gear Teeth.
