PLANETARY REDUCTION GEAR Russian patent published in 2007 - IPC F16H3/74 

FIELD: mechanical engineering.

SUBSTANCE: invention can be used in power drive of processing machines with large gear ratio at higher speed of rotation of input shaft, for instance, automatic trucks, piler drives. Proposed planetary reduction gear has input shaft 1 with gear 2, three peripheral shafts 3, 4, 5 with cylindrical gears 10, 11, 12, toothed coupling 13, bevel differential 14 arranged inside toothed coupling 13. Rim 20 of toothed coupling forms internal engagement with cylindrical gears 10, 11, 12 which are in meshing with cylindrical gear wheel 21 having hub with bevel gear 15 of differential. Rim 22 of toothed coupling forms toothed connection with cylindrical gear 23 having common hub with bevel gear 16 of differential. Axes of peripheral shafts are parallel to axis of central output shaft 6, being arranged at equal distance from said axis.

EFFECT: prevention of centrifugal forces, provision of any gear ratio of reduction gear, reduced overall dimensions of reduction gear.
