Abstract
A gear unit includes an inner shaft and an outer shaft concentrically arranged to make up two concentric output shafts; and a first and a second input shaft extending in a direction orthogonal to the output shafts and operatively connected to the inner shaft and the outer shaft, respectively. The inner shaft includes an inner gear attached thereto and the outer shaft includes an outer gear attached thereto. The inner gear and the outer gear are arranged in a mutually-opposing relationship. The first input shaft and the second input shaft are spaced apart from each other by a specified distance along an axial direction of the output shafts. The first input shaft includes a first input gear meshing with the inner gear and the second input shaft includes a second input gear meshing with the outer gear.
