A kind of external tooth meshing double propeller ship propeller with guide wheel

Abstract

The invention provides an external gearing double-paddle ship thruster provided with guide wheels and belongs to the technical field of ships. The external gearing double-paddle ship thruster comprises a main shaft, a drive gear, a driven gear, a driven gar shaft, a right positioning rod, a left positioning rod, a right annular plate paddle with teeth, a left annular plate paddle with teeth, a shell and a rudder. The drive gear is meshed with the driven gear. The axis of the left positioning rod, the axis of the driven gear shaft, the axis of the main shaft and the axis of the right positioning rod are located in the same transverse vertical face. The outer circumference of the left annular plate paddle with teeth and the outer circumference of the right annular plate paddle with teeth are each provided with a circle of teeth capable of being meshed with the driven gear and the drive gear, both the left annular plate paddle with teeth and the right annular plate paddle with teeth are installed in the shell and installed on the left positioning rod and the right positioning rod in a sleeving mode respectively, and the top of a half-arc body of the left annular plate paddle with teeth and the top of a half-arc body of the left annular plate paddle with teeth are provided with the guide wheels. The lower surface of a top plate of the shell is symmetrically provided with a left guide rail and a right guide rail. Power drives the left annular plate paddle with teeth and the right annular plate paddle with teeth to conduct reverse semi-circumference movement at the same time, strong forward thrust can be generated, efficiency is high, and operation is steady.

Description

technical field [0001] The utility model relates to an external tooth meshing double-blade ship propeller with a guide wheel, which belongs to the technical field of ships, and in particular relates to a ship propeller. Background technique [0002] Most traditional ship propellers use propellers. Although they are easy to drive, their efficiency is low. The manufacturing process of the blades is complicated, and wakes will be generated when they are used. After the water enters and before the water exits, the water resistance is large and the thrust generated is very small, the energy loss is large, the efficiency is low, and the noise is large. Authorized notification number is the patent of CN100360378C, discloses a kind of bionic flat ship propeller, although efficiency is higher, structure is more complicated. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the traditional ship propulsion technology, and to i...

AI Technical Summary

Problems solved by technology

[0002] Most traditional ship propellers use propellers. Although the drive is convenient, the efficiency is low, the manufacturing process of the blades is complicated, and wakes will be generated when used; the traditional paddle wheel propellers have water splashing when used, and the water splashes are large, and the blades are stiff. After the water enters and before the water exits, the water resistance is large and the thrust generated is small, the energy loss is large, the efficiency is low, and the noise is large

The patent with authorized notification number CN100360378C discloses a bionic flat ship propeller, although the efficiency is high, but the structure is relatively complicated
