FIELD: machine building.
SUBSTANCE: invention relates to the machine building. Planetary worm-spiroid reducer comprises coaxial input and output shafts, consists of input stage, which is a non-orthogonal worm gear, and an output stage, which is a non-orthogonal spheroid gear with a first worm-satellite, fixed and movable spheroid wheels, wherein the latter is rigidly connected to the output shaft of the reduction gear. In the reduction gear there introduced is the second satellite worm coaxial to the first worm-satellite rigidly connected to it and located relative to it on the other side from the interaxle line of the reduction gear, at that the fixed wheel is in engagement with the second worm-satellite.
EFFECT: higher efficiency factor of reduction gear.
