The invention provides a spiral groove gas 
dynamic pressure bearing test device, and belongs to the technical field of 
spiral groove bearing detection. The spiral groove gas 
dynamic pressure bearing testing device comprises a spiral groove gas 
dynamic pressure bearing to be tested, the spiral groove gas dynamic pressure bearing comprises a 
stator and a rotor which are arranged in a matched mode, and a driving shaft is coaxially arranged on the side, away from the 
stator, of the rotor; the device further comprises a 
rack unit, a positioning unit, a driving unit and a control analysis unit, the 
rack unit comprises a supporting base, a rotating support and a bearing support, the positioning unit is used for controlling the inclination angle of the rotating support, and the driving unit is used for driving the rotor to rotate. The control analysis unit comprises a control mechanism, a 
torque sensor and a 
vibration sensor. The friction performance and the stability performance of the spiral groove gas dynamic pressure bearing can be tested and displayed, the 
gas lubrication characteristic, the dynamic stability and other characteristics of the bearing can be visually displayed to students, and a 
simulation verification test can also be carried out.
