FIELD: mechanical engineering.
SUBSTANCE: precision planetary gear comprises a gear wheel, a movable annular gear, a fixed annular gear and one or more planetary gears. Each planetary gear is capable of being simultaneously connected to a toothed wheel, a fixed annular gear and a movable annular gear. The toothed wheel comprises a gear with a conical toothed crown, wherein each planetary gear comprises a gear with a conical gear ring, and the conical gear ring has a correction (x) linearly changing along the longitudinal direction of the tooth (Z), wherein each tooth (Z) of conical gear ring has a thickness (s) and a height (h) which vary when moved from the vertex (V) of said conical gear along the longitudinal direction of the tooth (Z).
EFFECT: ensured is improved performance.
