The invention relates to a device for simulating space weightless rotation, in particular to a friction-free air floating space weightless rotation simulation device. The two ends of an air floating main shaft are connected with a left shaft end plate shaft and a right shaft end plate shaft respectively; the left shaft end plate shaft and the right shaft end plate shaft are mounted on a base body by shaft supports respectively; a shaft sleeve of an air floating shaft sleeves the air floating main shaft; a gap is formed between the shaft sleeve of the air floating shaft and the air floating main shaft; an air pipe which is used for introducing air into the gap is arranged on the left shaft end plate shaft; when a torque motor is powered off, a friction-free state is formed between the air floating main shaft and the shaft sleeve of the air floating shaft; a torque motor rotor rotational connection sleeve is connected with one side of the shaft sleeve of the air floating shaft; a torque motor rotor sleeves the right shaft end plate shaft and is connected with the torque motor rotor rotational connection sleeve; a torque motor stator is mounted on the right shaft end plate shaft by a stator pressing ring; a rotor sleeve is located between the torque motor rotor and the torque motor stator. By the aid of the friction-free air floating space weightless rotation simulation device, the friction force is reduced to the greatest extent; the rotation precision is guaranteed, the structure is simple, the installation is convenient and the maintenance is convenient.
