The invention belongs to the technical field of ship propellers, and particularly relates to a shaft end fixing device of a ship propeller. A shaft end self-locking fixing device of a ship propeller comprises a locking cap with a spherical limiting block and a propeller shaft with an inner cavity in one end. The locking cap is arranged at the end of the propeller shaft in a sleeving mode, and the spherical limiting block is embedded into an inner cavity of the propeller shaft. A groove is formed in the outer wall of the inner cavity, and a rotary locking mechanism is arranged in the groove; and the rotary locking mechanism is used for locking the locking cap and the propeller shaft through rotation. According to the shaft end self-locking fixing device of the ship propeller, when the propeller blades rotate, the rotation locking mechanism arranged in the propeller shaft is matched with the spherical limiting block of the locking cap, fixing of the propeller shaft end is completed, threaded connection is not needed, the connecting effect is reliable, loosening is not likely to happen, and dismounting is convenient.

    本发明属于船舶推进器技术领域,具体涉及船舶螺旋桨的轴端固定装置。一种船舶螺旋桨的轴端自锁紧固定装置,包括具有球形限位块的锁紧帽、和一端具有内部空腔的螺旋桨轴;所述锁紧帽套在所述螺旋桨轴的端部,球形限位块嵌入所述螺旋桨轴的内部空腔;在内部空腔的外壁上开设有凹槽,所述凹槽内设有旋转锁紧机构;所述旋转锁紧机构通过旋转将所述锁紧帽与螺旋桨轴锁紧。本发明的船舶螺旋桨的轴端自锁紧固定装置,当桨叶旋转时,通过螺旋桨轴内设置的旋转锁紧机构,与锁紧帽的球形限位块配合,完成螺旋桨轴端的固定,无需使用螺纹连接,连接效果可靠,不宜松动,拆卸方便。
