CN201411036Y - Marine propeller with beaming ring - Google Patents

Abstract

The utility model relates to a marine propeller, in particular to a marine propeller with a beaming ring, which is a novel marine propeller with the beaming ring and a propelling blade which are connected together, achieving the effects of beaming, guiding streams and improving propelling efficiency, and avoiding the hazard of friction or collision of the propelling blade and a fixed guiding cover.

Description

The ship propeller of band line circle

Affiliated field

The utility model relates to a kind of ship propeller, particularly a kind of ship propeller with the line circle.

Technical background

Existing propelling unit generally adopts multi-disc vane type propelling unit, because this kind propelling unit can make the current that are pushed disperse along propelling unit rotating shaft normal direction when rotating, has reduced antagonistic force greatly, makes the propulsion coefficient step-down; Also have and install the fixedly pusher mechanism of streamlined reefer housing additional,, occur swing during owing to wheel rotation and can make blade and fixedly streamlined reefer housing friction or collide and cause damage though efficient has improved.

The utility model content

In order to overcome above-mentioned defective, the utility model proposes a kind of with line circle and the New Marine propelling unit that advances blade to link together, promptly reach the effect of line, water conservancy diversion, raising propulsion coefficient, avoided advancing blade and the fixedly harm of streamlined reefer housing friction or collision again.

The technical scheme in the invention for solving the technical problem is: will have the line circle of water conservancy diversion, line effect and advance blade to link together.

The beneficial effects of the utility model are: line circle and advance blade rotations that link together, promptly reached the effect of line, water conservancy diversion, raising propulsion coefficient, and avoided propelling blade and the fixedly harm of streamlined reefer housing friction or collision again.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Reference numeral: line circle (1), propelling blade (2), the blade base of a fruit (3), keyway axis hole (4).

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified:

The blade base of a fruit (3) is provided with keyway axis hole (4), so that link with the ship power axle; The blade base of a fruit (3) is gone up to link propelling blade (2), advance the other end of blade (2) to be attached on the line circle (1), like this, when the ship power axle promotes the blade base of a fruit (3) rotation, advance blade (2) and line circle (1) to rotate together, promptly reached line, guide functions, improved propulsion coefficient, blade and the fixedly harm of streamlined reefer housing friction or collision when having avoided the work of existing propelling unit again.

Claims (1)

1. the ship propeller of band line circle be is characterized in that by line circle (1), propelling blade (2), the blade base of a fruit (3), keyway axis hole formations such as (4): advance an end and the line circle (1) of blade (2) to link together.
