Abstract
A kind of tubular disk of conical profile marine propeller is related to a kind of marine propeller, including main shaft, bracket, disk of conical profile and tubular shell.Main shaft is rack-mount by bearing.Disk of conical profile includes preceding end disc, rear end annulus and several identical blades being evenly distributed.The section of blade is aerofoil profile.Before the vaned root of institute is all mounted on end disc, the vaned tip of institute is all mounted on the annulus of rear end.The angle of the extended line backward in the length direction and main shaft of blade is acute angle.The preceding end disc of disk of conical profile is connected with main shaft.Main shaft is in the front of disk of conical profile, and power is inputted from main shaft.Disk of conical profile is completely in tubular interior of shell.Power drives disk of conical profile rotation by main shaft, then will squeeze out from the rear of tubular shell in the water inspiration tubular shell in front.Propeller efficiency of the present invention is higher, and compared with traditional screw propeller, outer diameter is much smaller when thrust is identical, and resistance is smaller.
Description
Technical field
A kind of tubular disk of conical profile marine propeller is related to a kind of marine propeller more particularly to a kind of tubular ship
Ship propeller.
Background technique
Traditional marine propeller is propeller, blade substantially in the rotation in surface vertical with shaft, outer diameter compared with
Greatly, resistance is larger, and especially pressure drag and form drag is larger, and because sectional area is larger, install required horizontal space compared with
Greatly.
Summary of the invention
It is an object of the invention to overcome above-mentioned the deficiencies in the prior art, a kind of lesser tubular taper leaf of resistance is provided
Take turns marine propeller.
The technical scheme is that：A kind of tubular disk of conical profile marine propeller, including main shaft, bracket, taper leaf
Wheel and tubular shell.Main shaft is rack-mount by bearing, and bracket is connected with tubular shell.Main shaft is in tubular shell
Diametrical direction be centrally arranged.Main shaft is consistent with the opening direction of tubular shell.Disk of conical profile includes preceding end disc, rear end circle
Ring and several identical blades being evenly distributed.The section of blade is aerofoil profile.The vaned root of institute is all mounted on front end circle
On disk, the vaned tip of institute is all mounted on the annulus of rear end.The angle of the extended line backward in the length direction and main shaft of blade
For acute angle.The preceding end disc of disk of conical profile is connected with main shaft.Main shaft is in the front of disk of conical profile, and power is inputted from main shaft.Cone
Shape impeller is completely in tubular interior of shell.
To improve efficiency, the internal diameter of tubular shell is slightly larger than the outer diameter of the rear end annulus of disk of conical profile.Tubular shell
Internal diameter and disk of conical profile rear end annulus outer diameter difference between 1 ~ 5mm.The length direction of blade and prolonging backward for main shaft
The angle of long line is not more than 60 °.Bracket uses tripod.
A kind of tubular disk of conical profile marine propeller of the present invention works in this way, and power drives taper leaf by main shaft
Then wheel rotation, blade will squeeze out in the water inspiration tubular shell in front from the rear of tubular shell.Since main shaft is in
Front, water flow not will receive the resistance of power device by the process that disk of conical profile acceleration is flowed backward, and due to tubular shell
Presence, therefore the propeller efficiency is higher.
A kind of the advantages of tubular disk of conical profile marine propeller of the invention is：Compared with traditional screw propeller,
The outer diameter of propeller of the present invention is much smaller when thrust is identical, and efficiency is similar with traditional propeller；Propeller of the present invention is most
Resistance is smaller when prominent advantage is high speed.
Detailed description of the invention
Fig. 1 is a kind of schematic diagram of tubular disk of conical profile marine propeller of the present invention, and Fig. 2 is the top view of Fig. 1.Figure
In：1 is main shaft, and 2 be bracket, and 3 be disk of conical profile, and 31 be preceding end disc, and 32 be blade, and 33 be rear end annulus, and 4 is outside tubulars
Shell, 5 indicate streamline, and the hollow arrow on right side indicates the direction of advance of propeller of the present invention in Fig. 1.
Specific embodiment
The present invention is illustrated with reference to the accompanying drawing：Referring to attached drawing, a kind of tubular disk of conical profile marine propeller, packet
Include main shaft 1, bracket 2, disk of conical profile 3 and tubular shell 4.Main shaft 1 is mounted on bracket 2 by bearing, bracket 2 and tubular
Shell 4 is connected.Main shaft 1 is centrally arranged in the diametrical direction of tubular shell 4.The opening direction one of main shaft 1 and tubular shell 4
It causes.Disk of conical profile 3 includes preceding end disc 31, rear end annulus 33 and several identical blades 32 being evenly distributed.Blade 32 breaks
Face is aerofoil profile.Before the root of all blades 32 is all mounted on end disc 31, the tip of all blades 32 is all mounted on rear end
On annulus 33.The angle of the extended line backward in the length direction and main shaft 1 of blade 32 is 50 °.The preceding end disc 31 of disk of conical profile 3
It is connected with main shaft 1.Main shaft 1 is in the front of disk of conical profile 3, and power is inputted from main shaft 1.Disk of conical profile 3 is completely in tubular
Inside shell 4.The difference of the outer diameter of the rear end annulus 33 of the internal diameter and disk of conical profile 3 of tubular shell 4 is 2mm.Bracket 2 uses three
Foot prop.
The propeller works in this way：Power drives disk of conical profile 3 to rotate by main shaft 1, and blade 32 is by the water in front
It is then squeezed out from the rear of tubular shell 4 in inspiration tubular shell 4.Since main shaft 1 is in front, water flow is by disk of conical profile
The process that 3 acceleration are flowed backward not will receive the resistance of power device, and due to the presence of tubular shell, therefore the propeller is imitated
Rate is higher.
