PLANETARY GEAR WITH CONTROLLED GEAR RATIO Russian patent published in 2020 - IPC F16H35/02 F16H3/44 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, particularly, to mechanisms intended for transfer of rotation with controlled gear ratio, and can be used in transmissions of various machines for both transport and process purposes. Planetary gear includes housing 1, hinge 2 with two degrees of freedom, output shaft 3 connected to driven link of hinge 2, input shaft 4 connected with carrier 5, which, in its turn, is connected with satellite gear 6. Satellite 6 is rigidly connected to the driving link of hinge 2, and output shaft 3 is connected to the driven link of same hinge 2. Center of mass of satellite 6 is fixed and formed by coinciding with center of hinge 2, geometrical axis 7 of satellite 6 is inclined relative to axis of output shaft 3 by alternating nutation angle θ, carrier 5 with satellite 6 are installed with possibility of performing regular precession movement relative to fixed center of hinge 2. Axis of precession is axis of output shaft 3, and kinematic connection of pinion 6 with housing 1 is configured to eliminate rotation of satellite 6 relative to its geometric axis of rotation 7, for example, in the form of a gear bevel gear using, in particular, a forging engagement or in the form of a friction gear.

EFFECT: provides increased load transfer capacity.
