Abstract:
1. A dual-shaft synchronous movement device comprising: a first shaft and a second shaft each having a fixed end and a pivoted end; a first rotor and a third rotor disposed on the first shaft; and a second rotor and a fourth rotor disposed on the second shaft, a first drive section disposed between the first and second rotors and a second drive section disposed between the third and fourth rotors for synchronously rotating the first and second shafts; wherein the first, second, third, and fourth rotors are in the form of rollers; the first and third rotors non-rotatably engage the pivoted end of the first shaft; the second and fourth rotors non-rotatably engage the pivoted end of the second shaft; and wherein the first and second drive sections are wound about and frictionally assembled on respective pairs of the first, second, third, and fourth rotors to minimize torque change or slippage.
