ABSTRACT:
A load distributing planetary gear or epicyclic transmission having a sun gear, an annulus gear and a planet wheel carrier supporting a plurality of planet wheels, all of the gears being helical and the planet wheels being simultaneously meshed with the sun gear and the annulus gear. Each planet wheel is mounted on a distal end of a flexible shaft, which is supported by the planet wheel carrier on an opposite end, by a journal which permits swivelling of the planet wheel. Each planet wheel is held in place by a component which is capable of sliding only in a plane extending substantially perpendicular to a plane passing through the axis of rotation of the planet wheel and the axis of rotation of the sun gear. The sliding component is offset axially along these axes relative to the planet wheel, preferably being located on the side of the planet wheel facing towards the planet wheel carrier. The sliding components constitute a reversal torque compensating device which prevents tipping or swivel movement of the planet wheel caused by the reversing torque due to the engagement of the helical gears.
