FIELD: mechanical engineering. SUBSTANCE: transmission has planetary speed regulator, regulating link and rotary levers. Regulating link has static members for loading rotary levers and causing them to rotate in direction reducing transmission ratio from high rotational speed shaft to low rotational speed shaft. Profiled surfaces of regulating link may be disposed on rotary levers or on member connected with low rotational speed shaft. Profiled surfaces are made spiral, with direction of spirals providing angular displacement of rotary levers in direction causing increase in transmission ratio of speed regulator, when carrier is ahead of planetary speed regulator. Profiled surfaces may be also provided with profile variable in axial direction and may be positioned for axial displacement relative to pushers. EFFECT: increased efficiency by improved precision and enhanced reliability in operation. 10 cl, 1 dwg |
