Variable speed ship propeller

Abstract

The invention provides a variable speed ship propeller. The variable speed ship propeller comprises a first conical gear, a speed changer, a second conical gear, a third conical gear, a transmission shaft, a protective net, a conical guide pipe, a cylindrical jetting guide pipe, a propeller, a fourth conical gear, a coupling and an alternating current variable frequency asynchronous motor; the protective net is arranged on the right side of the third conical gear; the conical guide pipe is mounted at the right end of the protective net; the cylindrical jetting guide pipe is assembled at the right end of the conical guide pipe; the third conical gear is connected with the propeller through the transmission shaft; the third conical gear is engaged with the second conical gear; the alternating current variable frequency asynchronous motor is mounted at the right end of the coupling; the fourth conical gear is connected with the coupling through a connecting shaft; the fourth conical gear is engaged with the first conical gear. The variable speed ship propeller is convenient to use and convenient to operate, and can change speed at a plurality of levels; the propelling efficiency of the propeller is improved; the stability is good; the reliability is high.

Description

technical field [0001] The invention relates to a variable-speed ship propeller propeller, which belongs to the technical field of ship propulsion. Background technique [0002] In current motor ships, the propellers are all equipped with external propellers at the tail. The limitation of the engine power on the existing propellers makes it less efficient, resulting in a lack of good balance and stability of the hull. In addition, since the propeller is external, it is very easy to entangle water plants and other sundries, which will affect the normal running of the ship. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a variable-speed ship propeller propeller to solve the problems raised in the above-mentioned background technology. The present invention is easy to use, easy to operate, multi-stage variable speed, and improves the propulsion efficiency of the propeller , good stability and ...
