The invention discloses a reinforcing shaft for the ship driving system; the shaft comprises a shaft body, a spline is connected to the upper portion of the shaft body in a sleeving mode, one or more threaded holes are sequentially formed in the outer wall of the shaft body in the length direction of the shaft body at intervals, and first through holes aligned with the threaded holes are formed in the spline; a locking screw is inserted into the first through hole and is in threaded connection with one threaded hole; more than one fixing hole is annularly formed in the upper portion of the spline, and the shaft body comprises an inner shaft sleeve and an outer shaft sleeve; and a reinforced steel wire mesh is arranged between the inner shaft sleeve and the outer shaft sleeve; More than one first reinforcing rib is annularly embedded in the outer shaft sleeve, more than one second reinforcing rib is annularly arranged outside the inner shaft sleeve, one second reinforcing rib is arranged between every two adjacent first reinforcing ribs, and the second reinforcing ribs abut against the two adjacent first reinforcing ribs. And the first reinforcing ribs and the second reinforcing ribs extend along the length direction of the shaft body. The structure improves the strength of the shaft body.
