The utility model discloses a dual-input expanded-form two-stage parallel-shaft hard tooth surface speed reducer, and adopts the scheme that two input gear shafts (1) are symmetrically arranged at two ends of the same side surface of a body (6), and two parallel shafts are staggered and are simultaneously input to be engaged with split-type transition helical gears (4) installed on two transition gears (3); the rotating direction of the two input gear shafts is reverse to that of the engaged split-type transition helical gears; then transition gear shafts used for installing the split-type transition helical gears come together with an output shaft (5) arranged in the center of the body, to enable helical gears arranged on the transition gear shafts to simultaneously engaged with split-type output helical gears (4) installed on the output shafts, to form power confluence centralized output; and the rotating direction of the two transition gear shafts is reverse to that of the engaged split-type output helical
