The invention relates to a bearingless thrust vectoring nozzle driving device which comprises a fixed base and a rotating ring, the fixed base and the rotating ring are combined to form a closed annular cavity, a check block is arranged on the rotating ring and divides the annular cavity into two parts, and an inlet and an outlet of a fluid medium are formed in the fixed base. A fluid medium is injected into the annular cavity on one side through the inlet and then pushes the check block and the rotating ring to move, and then the thrust vectoring nozzle installed on the rotating ring is driven to rotate. Compared with the prior art, the bearingless thrust vectoring nozzle driving device provided by the invention has the advantages that a connecting bearing is omitted, the device structure is simplified, the weight and the size of the device are reduced, and corrosion of a marine environment is avoided. 本发明涉及一种无轴承矢量喷管驱动装置，包括固定底座、旋转环，所述固定底座与旋转环组合形成闭合环形腔体，所述旋转环上设置挡块，将环形腔体分为2部分，所述固定底座上设置有流体介质的入口及出口。所述流体介质通过入口注入一
