    摘要： A drive for a harmonic gear assembly, comprising an input shaft having a shaft axis (A) and an epicyclic carrier unit removably mounted around, and coaxial with the input shaft, the epicyclic carrier unit comprising a carrier (40) having an interior circumference designed to match the outer circumference of the shaft and further comprising a first roller assembly (42a, 50a) mounted at a first location around the circumference of the carrier unit and comprising a first roller shaft (42a) extending substantially parallel to the shaft axis and a first roller (50a) rotatably mounted around the first rotor shaft, and a second roller assembly mounted at a second location around the circumference of the carrier unit and comprising a second roller shaft (42b) extending substantially parallel to the shaft axis and a second roller (50b) rotatably mounted around the second rotor shaft, the first and second rollers extending radially outwards from the carrier to define a major axis between the radially outer surfaces of the first and second rollers, and wherein the outer surface of the carrier unit at locations other than the first and second locations defines a minor axis:
