PLANETARY GEAR Russian patent published in 2015 - IPC F16H1/28 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to mechanisms providing the orbital movement of disks (wheel) of a reducer and can be used as the mechanism converting the rotary motion into the reciprocating one. The planetary gear contains an input pinion (1), an external ring (2) and satellites (4, 5) with different diameters fitted with rims. The external ring (2) is fitted with the mechanism preventing its free rotation around its own axis, for this purpose it is pivotally connected to a crosshead (7) in a longitudinal cut (8). All the satellites (4 and 5) are seated on one free spider (6) in such a manner that the satellite of the greater size (4) is in simultaneous linkage with the pinion (1) and the external ring (2) and is made with the size ensuring an eccentric offset of the external ring (2) with reference to the central axis. The satellites of the smaller size (5) are engaged only with the external ring (2).

EFFECT: invention allows eliminating the influence of assembly conditions on the gear operation, expands the range of possible sizes of the eccentricity and increase the load capability of the planetary gear.
