The invention belongs to the technical field of helicopter rotor structures, and particularly relates to a bearingless paddle connecting structure. Comprising a flexible beam, two supporting bearings, a supporting bearing support, a support fixing bolt, a cover plate, a cover plate connecting bolt, a wear-resisting plate, a tail shaft, blades and a tail rotor flange, the two ends of the flexible beam are each provided with one blade, the flexible beam and the blades are integrally formed, and the roots of the blades are connected with the tail rotor flange through bolts. The supporting bearing support is fixed to the flexible beam through support fixing bolts and used for supporting the two supporting bearings on the upper side and the lower side of the flexible beam. One end of the support bearing is connected with the tail rotor flange, and the other end is connected with the support bearing bracket; the flexible beam is clamped between the cover plate and the tail shaft, and a wear-resisting plate is arranged on the clamping interface of the cover plate and the flexible beam and is fixed through a cover plate connecting bolt.
