Problems solved by technology
During the underwater rotation of the propeller, according to the needs of the ship's working conditions, the lock nut 101 will always rotate with the forward and reverse rotation of the propeller, and it is easy to loosen. If the tightening nut is loose, it will affect the propulsion efficiency of the propeller. When the locking nut falls off, the propeller blade 103 will fall off, which will affect the navigation safety of the ship.
[0005] In addition, if the lock nut is soaked in water for a long time, the threaded parts will be corroded, resulting in that the lock nut cannot be disassembled, and the propeller shaft needs to be damaged during maintenance, which will increase the maintenance cost and increase the difficulty of maintenance

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 and fixing device for a ship propeller, comprising a locking cap with a spherical limit block, and a propeller shaft with an internal cavity at one end; the locking cap is sleeved on the end of the propeller shaft, and the spherical The limit block is embedded in the inner cavity of the propeller shaft; a groove is formed on the outer wall of the inner cavity, and a rotary locking mechanism is arranged in the groove; the rotary locking mechanism locks the The cap is locked to the propeller shaft. The self-locking and fixing device of the shaft end of the ship propeller of the present invention, when the blade rotates, the rotation locking mechanism arranged in the propeller shaft cooperates with the spherical limit block of the locking cap to complete the fixing of the shaft end of the propeller, without using Threaded connection, reliable connection effect, not loose, easy to disassemble.
Description
technical field [0001] The invention belongs to the technical field of marine propellers, and in particular relates to a shaft end fixing device of a propeller. Background technique [0002] International shipping links all countries and regions in the world, and shipping realizes the communication and exchange of technology, economy and trade with each other. Universally linked, shipping thus transforms production and consumption into a worldwide, global activity. [0003] As the main means of transport in international shipping, compared with other means of transport, ships have the advantages of large carrying capacity and low operating costs. With the development of the world economy, modern transport ships have formed a huge fleet of various types, complex technologies and high specialization. Considering the factors of energy saving and economy, the main propulsion method of modern transport ships is the propeller. [0004] For equipment with high-speed operation of...
