PLANETARY GEAR Russian patent published in 2014 - IPC F16H1/32 

FIELD: machine building.

SUBSTANCE: planetary gear comprises an eccentric planet carrier (1), two planet pinions (2) with outer teeth, a stationary central gear wheel (3) with inner teeth, a driven shaft (4) and a mechanism to take over the motion from the pinions consisting of two unsupported disks (6) with holes where rubber bushes (7, 8) are set with tension, of pins (5) of the driven shaft and pins (9) of the pinions. Half of the rubber bushes (7) is set with tension on the pinions pins (9), the other half (8) - on the pins (5) of the driven shaft (4). Radial shift of every pinion (2) for the value of gear interaxle distance is provided by the summation of the deformation of the rubber bushes (7) set on the pinion pins (9) and of the radial movement of the unsupported disks (6) due to the deformation of rubber bushes (8) set on the driven shaft pins (5).

EFFECT: in the process of force and movement transfer the rubber bushes set in the holes of unsupported disks and on the pins provide for damping of impact loads reducing noise level.
