Abstract:
A planet gear consisting essentially of a central, rotatable input axle (1a); at least three planet wheels (6); stays (7); a centrally-disposed sun axle (2); anda flexible outer ring (4) which under elastic deformation surrounds and presses the at least three planet wheels (6) in the form of rollers radially up against a centrally-disposed sun axle (2) which extends axially in line with the input axle (1a), said planet wheels (6) having central holes and being rotatably mounted on the stays (7), diameters of the stays being smaller than the holes in the planet wheels, center lines of the stays being parallel with the sun axle, center lines of the stays disposed closer to the sun axle than axes of the planet wheels when the planet wheels lie up against the sun axle, the input axle (1a) including a firmly connected disk-shaped driver (1), a side of which is provided with circular-cylindrical holes (3) for the engagement of circular-cylindrical studs of the flexible outer ring (4), the circular-cylindrical holes disposed on a pitch circle diameter which is smaller than a pitch circle diameter for the studs of the outer ring when the outer ring is in an unloaded state.
