The invention relates to a high-lift air flotation high-precision gravitational unloading device, which belongs to the aeronautic and astronautic technical field of ground microgravity simulation experiment platforms. The invention is intended to solve the problem that defects exist in conventional microgravity and low-gravity simulation equipment. A code disc type low-power electromotor, a code disc type high-power electromotor, a unilateral air flotation normally-closed clutch, a third pulley, a speed reducer and a brake of the high-lift air flotation high-precision gravitational unloading device are mounted on a base, and the output rotary shaft of the code disc type low-power electromotor is in coaxiality and transmission connection with the left shaft of a large-diameter winding drum through a narrow-range torque sensor; the output rotary shaft of the code disc type high-power electromotor is in transmission connection with the right shaft of a small-diameter winding drum through the speed reducer, a wide-range torque sensor and the unilateral air flotation normally-closed clutch; after getting out of the groove of the large-diameter winding drum at a tangent, a first sling enters the groove of a first pulley. The high-lift air flotation high-precision gravitational unloading device is structurally compact; since a variety of air flotation devices are adopted, the motion damp of the device parts is reduced, the influence of part vibration is eliminated, the precision is high, and the reliability is high.
