Abstract
The invention discloses a high performance propeller comprising blades and a hub; the blades and hub are formed through one body moulding by casting technology; the hub is provided with a keyway pore structure; the blades comprise main blades and auxiliary blades arranged at intervals and uniformly arranged in the periphery direction of the hub. The high performance propeller is reasonable in structure design, unique in efficacy, and middle in making cost; the blades comprise main blades and auxiliary blades, wherein the main blades are used for cutting water, and the auxiliary blades are used for current stabilization; the structure design can effectively improve work stability of the propeller, and can ensure the propeller to have excellent driving force.
Description
Technical field
The present invention relates to a kind of screw propeller, particularly relate to a kind of stability and the excellent high performance propeller of driveability, belong to marine propeller technical field.
Background technology
Marine propeller is the mechanism promoting boats and ships advance, and it is energy converter natural force, manpower or mechanical energy being converted to boats and ships thrust.Marine propeller can be divided into active and reaction equation two class by the mode of action, and the fibre relying on manpower or wind-force to drive ship to advance, sail are active propelling unit, and relying on oar, big shield, paddle wheel, screw propeller to drive, ship advances is reaction equation propelling unit.Modern ships that transport adopts reaction equation propelling unit mostly, is wherein most widely used with screw propeller.
Marine propeller forms by propeller hub with along the blade that propeller hub circumferencial direction is uniform usually, and both adopt foundry technique one-body molded, and stability is excellent.The quantity of existing marine propeller blade can according to ship power need be not set to 3-8 not etc., its specification is identical, more moneys on exhibit and lesser moneys on counterfoil; In the working process of screw propeller, all adopt large end-grain cutting water, small end current stabilization, but often there is the phenomenons such as liquid resistance is excessive, liquid stream unstable, propulsive effort is not enough.For this reason, people arrange line barrel structure in the outer ring of screw propeller, with stabilizing solution stream, guarantee propulsive effort, but greatly enhance preparation technology and the cost of screw propeller.
Summary of the invention
For the demand, the invention provides a kind of high performance propeller, the design of this propeller arrangement is unique, its blade is made up of primary blades and back blades, and primary blades cuts water, back blades current stabilization, effectively raise the working stability of screw propeller, guarantee its good propulsive effort.
The present invention is a kind of high performance propeller, this screw propeller comprises blade and propeller hub, both adopt foundry technique one-body molded, described propeller hub is offered dowel hole structure, described blade is made up of primary blades and back blades, described major and minor spacing with blades is arranged, and uniform along the circumferencial direction of propeller hub.
In a preferred embodiment of the present invention, the thickness of described primary blades root is suitable with the thickness of back blades root.
In a preferred embodiment of the present invention, the length of described primary blades is about 2 times of back blades length.
In a preferred embodiment of the present invention, the radian of described back blades working end is about 2 times of primary blades working end radian.
In a preferred embodiment of the present invention, the quantity of described major and minor blade is identical, is generally 6 or 8.
The invention provides a kind of high performance propeller, this propeller arrangement is reasonable in design, effect is unique, preparation cost is moderate, its blade is made up of primary blades and back blades, and primary blades is responsible for cutting water, and back blades is responsible for current stabilization, this structure design effectively can improve the working stability of screw propeller, guarantees its good propulsive effort.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of embodiment of the present invention high performance propeller;
In accompanying drawing, the mark of each parts is as follows: 1, blade, and 2, propeller hub, 3, dowel hole, 4, primary blades, 5, back blades.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Fig. 1 is the structural representation of embodiment of the present invention high performance propeller; This screw propeller comprises blade 1 and propeller hub 2, both adopt foundry technique one-body molded, and described propeller hub 2 is offered dowel hole 3 structure, described blade 1 is made up of primary blades 4 and back blades 5, described major and minor spacing with blades is arranged, and uniform along the circumferencial direction of propeller hub 2.
In the high performance propeller that the present invention mentions, the thickness of primary blades 4 root is suitable with the thickness of back blades 5 root, and this structure design can guarantee that major and minor blade has suitable intensity, guarantees the service life of screw propeller entirety.
The length of primary blades 4 is about 2 times of back blades 5 length; The radian of back blades 5 working end is about 2 times of primary blades 4 working end radian; This structure design makes the effect of back blades 5 wheeled current stabilization, and make the serviceability of screw propeller entirety more stable, propulsive effort is more concentrated and efficient.
The quantity of major and minor blade is identical, is generally 6 or 8, amount can be larger waters in, its quantity prioritizing selection is 6.
Present invention is disclosed a kind of high performance propeller, be characterized in: this propeller arrangement is reasonable in design, effect is unique, preparation cost is moderate, its blade is made up of primary blades and back blades, and primary blades is responsible for cutting water, and back blades is responsible for current stabilization, this structure design effectively can improve the working stability of screw propeller, guarantees its good propulsive effort.
The above; be only the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the present invention; the change can expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
