Claim Text:
1. A torque balancing device applied to synchronous dual-shaft system, comprising: a first rotary shaft; a second rotary shaft; and a torque balancing unit assembled with the first and second rotary shafts, the first and second rotary shafts being defined with an axial direction, each of the first and second rotary shafts having a fixed section, a link section, a drive section and a pivoted section, the torque balancing unit including a reactor and a responder assembled with each other, each of the reactor and the responder having a central section and wing sections protruding from the central section, said central section having an axis of rotation positioned between said first and secondary rotary shafts and said axis of rotation being aligned in said axial direction, the drive section of the first rotary shaft having at least one plane section and an arched section connected with the plane section, the drive section of the second rotary shaft having at least one plane section and an arched section connected with the plane section, the wing sections of the reactor and the responder together releasably engaging the at least one plane section of each of the drive sections of the first and second rotary shafts in a first state, when the first and second rotary shafts rotate, the wing sections being forcedly moved to release the at least one plane section of each of said drive sections by the rotation of said arch section of each of said drive sections and the reactor and the responder being moved in the axial direction relative to each other; wherein the central section of the reactor being formed with at least one raised section and recessed section and the central section of the responder being formed with at least one raised section and recessed section, the raised section and the recessed section of both said reactor and said responder being arranged in adjacency to each other, two sides of the raised section being inclined toward the recessed section to form a slope structure, the wing sections respectively diagonally protruding from each central section, whereby each of the reactor and the responder has two wing sections to form a substantially S-shaped cross section, a cut being formed between the wing sections and the central section, when said first and second rotary shafts rotate, said raised section of said reactor and said raised section of said responder are rotated to a position of contact providing an axial force for moving said reactor and said responder in said axial direction relative to each other.
