Abstract

The invention discloses a two-stage propeller for a ship, and relates to the technical field of ship propellers. The two-stage propeller comprises a front driving device and a rear driving device, wherein the front driving device and the rear driving device are in transmission connection through a telescopic universal coupling; the front driving device comprises a power main shaft; two impellers are fixed in the middle of the power main shaft; a first transmission gear is fixed to the peripheral side face of the power main shaft and located between the two impellers. The first transmission gear is in meshing transmission fit with a second transmission gear; a coaxially arranged transmission main shaft is fixed at one end of the second transmission gear; a first flange plate connected withthe universal coupling is fixed at the end part of the transmission main shaft; and a first retainer is arranged on the transmission main shaft. Through combination of two power parts of the front driving device and the rear driving device, the pushing force is increased, power connection is conducted through the universal coupling, the overall structure is reasonable and simple, and operation isconvenient.

Description

technical field [0001] The invention belongs to the technical field of marine propellers, and in particular relates to a two-stage propeller for ships. Background technique [0002] Existing marine propulsion includes paddle wheel, propeller, straight wing, water jet, half-rotating blade and bionic propulsion. The paddle wheel propeller originated from the early steam-powered ships. It is a kind of propeller installed on the sides or stern of the ship and only the lower half enters the water; it is usually distinguished according to whether the web plate mounted on the paddle wheel rotates or not. It is a paddle wheel with fixed fins and paddle wheels with dynamic fins; the reaction force generated by its paddling pushes the ship forward. Some water recreation tools, such as water bikes, also use a simple and effective propulsion method similar to the paddle wheel. Because the paddle wheels of paddle steamers are mostly installed on the side and most of them need to be exp...
