The invention relates to the technical field of ship propellers, in particular to a gear-driven shaftless paddle propeller which comprises multiple paddle blades and a paddle blade driving gear, wherein the paddle blades are fixed to the inner surface of the paddle blade driving gear, and teeth are arranged on the outer surface of the paddle blade driving gear; a shell which is provided with an axial hollow cavity and a circumferential paddle blade mounting cavity, wherein water flow passes through the hollow cavity, and the paddle blade mounting cavity provides mounting space for the paddle blades and the paddle blade driving gear; a gearbox which is fixed on the shell, wherein a driving shaft and a transmission assembly matched with the driving shaft are arranged in the gearbox; the driving shaft stretches out of the gearbox to be connected with an external power system. The gear-driven shaftless paddle propeller is ingenious in design and novel in structure, not only has the advantages of cavitation inhibition and high efficiency, but also has the characteristics of high reliability and low cost of mechanical transmission, and has remarkable popularization and application significance.
