The utility model discloses a straightener with planetary inclined rollers and a rotating hub, which comprises a rotating hub, a first power driving device which drives the rotating hub to rotate, at least two groups of straightening rollers arranged in the rotating hub, and a second power driving device which drives the straightening rollers to autorotate; wherein the upper and lower straightening rollers of each group of straightening rollers are symmetrically arranged at two sides of the rotation axis; and the straightening rollers incline for certain angle relative to the rotation axis. The straightener adopts the combination of the autorotating straightening rollers and the revolving rotating hub, the original driven straightening rollers in the rotating hub are changed to be driving straightening rollers, and the phenomenon of the co-rotation of the spar to be straightened is eliminated by matching the rotation speed of the rotating hub and the straightening rollers, thus improving the contact and the press bending status of the straightening rollers and the spar to be straightened, which is good for improving the straightness. The straightening rollers driven by a hydraulic motor tightly clamp the spar to be straightened and roll around the spar to ensure the roundness of the spar. The straightener is quite suitable for straightening super-long thin-wall tubes.
