  • Bearingless planetary gearbox
    Patent number: 10941838
    Abstract: A planetary gearbox including a first sun gear; a first ring gear; a first set of planet gears meshing with the first sun gear and the first ring gear; a second sun gear; a second ring gear; a second plurality of planet gears meshing with the second ring gear and the second sun gear, wherein the ith gear in the first set of planet gears is fixed to the ith gear in the second set of planet gears so that the gears in the first set and the second set rotate together coaxially. The resulting planetary gearbox can be readily integrated into compact robotic joints. Its few lightweight components can be manufactured with high accuracy with standard machining techniques.
