FIELD: mechanical engineering; helicopter reduction gearboxes.
SUBSTANCE: proposed reduction gearbox for coaxial helicopter includes drive shaft, two coaxial driven shafts (inner and outer), gear train and planetary mechanisms which are kinematically interconnected; each mechanism includes sun gear wheel fitted on drive shaft and epicycle fitted on outer driven shaft. Gear train mechanism has idler units placed in carrier which is rigidly secured on inner driven shaft; number of satellites exceeds number of idler units by one; number of teeth of sun gear wheel and epicycle of gear train mechanism is multiple of number of idler units; total number of teeth of these members in planetary mechanism is multiple of number of satellites.
EFFECT: simplified construction of reduction gearbox; facilitated assembly; equality of opposite revolutions of coaxial shafts.
