The invention discloses a non-concentric elastic compensation sealing assembly. The non-concentric elastic compensation sealing assembly is characterized by comprising a rotary motion assembly and anaxial motion assembly, wherein the rotary motion assembly and the axial motion assembly sleeve a shaft, the axial motion assembly comprises a static sleeve fixedly installed with the shaft, the staticsleeve is provided with a movable sleeve capable of axially moving, and the movable sleeve is fixedly provided with a wear-resistant static ring; and the rotary motion assembly comprises an outer cover rotationally mounted on the shaft, a wear-resistant movable ring is fixedly arranged on the outer cover, and the wear-resistant static ring and the wear-resistant movable ring are matched and sealed. The static sleeve is provided with elastic teeth, and the static sleeve I penetrates through elastic tooth holes of the movable sleeve to be limited through the elastic teeth. The movable sleeve isinternally provided with an anti-rotation groove with a concave-convex structure, the wear-resistant static ring is provided with a wear-resistant static ring groove matched with the anti-rotation groove, the wear-resistant movable ring I is provided with a wear-resistant movable ring groove with a concave-convex structure, and the wear-resistant movable ring groove and an outer cover groove of the outer cover which has the corresponding convex-concave structure are matched and fixed.
