FIELD: aviation.
SUBSTANCE: invention relates to designs of helicopter rotor drive reduction gearboxes. Helicopter rotor reduction gear (1) has central cavity in which support shaft (13) passes, spatially and rotationally fixed, which is retained by reduction gear passing through casing (10) at least partially in direction of central axis (Z). Ring gear (12) with internal engagement of rotary shaft (14) of rotor can rotate around central axis (Z) with fixed rotation of satellites (11) relative to their axes (P), so that rotor shaft (14) can be rotated by means of driving element (140) of the ring gear attached to ring gear (12).
EFFECT: ensuring maintenance of normal lubrication for a longer period of time, wider service interval.
