For a planetary gear to create a ratio, one of the parts must be fixed, right? How to calculate the ratio in multistage planets. Is there a ratio in free rotating planets?

[@benargee]

It looks like the outer/top planetary gears rotate the inner/bottom sun gear. It looks like the hydraulic motor is directly attached to the top/outer sun gear you see spinning rapidly. The inner/bottom planetary gears look like they are fixed to the chassis and hydraulic motor body

how to calculate gear ratio? i am confused😌

[@haynillesen]

Number of teeth smallest gear wheel : number of teeth outer gear wheel ( inner teeth) 3 running gear wheels have no part in the equasion

[@haynillesen]

A very common ratio is about 1:6 , with 2 planetary sets of 1:6 you get a gear ratio of 1:36
