PLANETARY GEAR Russian patent published in 2016 - IPC F16H1/28 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, namely to planetary gear transmissions. Gear consists of a predetermined number of planetary gears and pinion frame with two walls carrying planetary gears. Gears are supported by support pins, defining the corresponding axis, end sections are fixed to appropriate wall of the carrier of planetary gear. In this wall on end section inside each of the support pin there is an annular groove, size of which along the axis is greater than that of the toothed rim of planet gear along the axis. Ring can be partially inserted into the groove and have a profile, which coincides with the profile part of the groove, in which it is inserted. This ring is used as a mechanical limiter for deformed pin part, that is deformed under action of pre-set load until contacts with ring.

EFFECT: compensation of non-uniformity of planetary gear load is performed.
