FIELD: mechanics.
SUBSTANCE: four-power takeoff multiengine gear system incorporates the first and second input and output shafts (10, 12), respectively, third shaft (42) linked to the first variable-speed gear (44, 46) and fourth shat (48) linked to the second variable-speed gear (50, 52). Four shafts (10, 12, 42, 48) are linked together by a twin planetary set of cone gears. The first aforesaid set does not reverse the gear running and incorporates the first and second sun gears (40, 28) in mesh with respective set of the first and second satellite gears (21, 26). The first (21) and second (26) satellite gears are fitted onto a common satellite shaft (24) linked to a common spider (22). The second planetary set of gears reverses the sense of rotation and incorporates the first sun gear (40) and third sun gear (38) in mesh with the set of third satellites (39). Different-diameter first and second satellites (21, 39) are linked to make a stepped multi-toothing satellite.
EFFECT: differential gear with four power takeoffs.
