  • Mechanical paradox planetary gear mechanism
    Patent number: 11187301
    Abstract: There is provided a mechanical paradox planetary gear mechanism, including: a sun gear configured to be rotatable together with rotation of an input shaft; a plurality of first planetary gears arranged around the sun gear at equal intervals, and configured to rotate about their own axes while revolving around the sun gear in a state in which the first planetary gears mesh with the sun gear; a first internal gear arranged around the plurality of first planetary gears, and configured to mesh with the plurality of first planetary gears; a second internal gear arranged in the same axis as the first internal gear; and a plurality of second planetary gears respectively arranged on the same axes as the plurality of first planetary gears, and configured to mesh with the second internal gear.
