Abstract
The invention discloses a high speed propeller comprising blades and a hub; the blades and the hub are arranged in a split mode, and are fixedly connected through bolts; the center of the hub is provided with a shaft hole; the surface of the blade is provided with speedup patterns employing fish scale patterns; the speedup patterns are formed by casting technology. The high speed propeller is provided, reasonable in structure design, proper in making cost, stable in performance, and the speedup patterns arranged on the surface of the blades can improve blade thrashing capability, thus improving driving performance of the propeller in certain level.
Description
Technical field
The present invention relates to a kind of screw propeller, particularly relate to a kind of high performance airscrew that effectively can improve screw propeller propulsive effort, 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 axis hole is offered at the middle part of propeller hub, and process keyway arrangements, axis hole is connected with transmission shaft, to realize the high speed rotating of screw propeller.Existing blade surface is smooth side, strikes and driveability all depends on the moment of torsion that the arcwall face of blade and transmission shaft transmit.The output torque of transmission shaft is subject to the restriction of motor and whole propeller performance, improves comparatively difficulty; Therefore, the structure of propeller blade is improved not for being a kind of good approach improving screw propeller power-handling capability.
Summary of the invention
For the demand, the invention provides a kind of high performance airscrew, this propeller arrangement is reasonable in design, and the speedup pattern structure of its blade surface processing effectively can improve the ability of striking of blade, improves the driveability of screw propeller to a certain extent.
The present invention is a kind of high performance airscrew, this screw propeller comprises blade and propeller hub, both adopt split manufacture, and use bolt to achieve a fixed connection, the middle part of described propeller hub processes axial aperture structure, the surface working of described blade goes out speedup pattern structure, and described speedup decorative pattern adopts fish scale design, and described speedup decorative pattern is shaping by foundry technique.
In a preferred embodiment of the present invention, the upper and lower surface of described blade is equipped with speedup decorative pattern.
In a preferred embodiment of the present invention, in described speedup decorative pattern, the specification of each unit pattern is identical, and spacing is identical.
In a preferred embodiment of the present invention, described speedup decorative pattern is arranged according to the profile of blade, and is covered with blade surface.
In a preferred embodiment of the present invention, the gross area of described speedup decorative pattern is about the 70%-75% of the blade gross area.
In a preferred embodiment of the present invention, described speedup decorative pattern is about 18-20 in the quantity on single paddle surface.
The invention provides a kind of high performance airscrew, this propeller arrangement is reasonable in design, and preparation cost is moderate, stable performance, and the speedup pattern structure that its blade surface is arranged has and promotes blade and to strike the function of ability, improves the driveability of screw propeller to a certain extent.
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 airscrew;
In accompanying drawing, the mark of each parts is as follows: 1, blade, and 2, propeller hub, 3, axis hole, 4, speedup decorative pattern.
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 airscrew; This screw propeller comprises blade 1 and propeller hub 2, both adopt split manufacture, and use bolt to achieve a fixed connection, the middle part of described propeller hub 2 processes axis hole 3 structure, the surface working of described blade 1 goes out speedup decorative pattern 4 structure, described speedup decorative pattern 4 adopts fish scale design, and described speedup decorative pattern 4 is shaping by foundry technique.
In the high performance airscrew that the present invention mentions, the upper and lower surface of blade 1 is equipped with speedup decorative pattern 4; In speedup decorative pattern 4, the specification of each unit pattern is identical, and spacing is identical; The lines of speedup decorative pattern 4 is vertical with the rotation direction of blade 1 in theory, and meanwhile, speedup decorative pattern 4 is evagination structure design, and maximum hill height is about 2mm, farthest adds effective working area of speedup decorative pattern 4.
Above-mentioned speedup decorative pattern 4 is arranged according to the profile of blade, and is covered with blade 1 surface, and this rational deployment effectively can reduce the undesirable stress that speedup decorative pattern 4 structure produces, and guarantees the service life that blade 1 is good; The gross area of speedup decorative pattern 4 is about the 70%-75% of the blade gross area; Speedup decorative pattern 4 is about 18-20 in the quantity on single paddle 1 surface.
Present invention is disclosed a kind of high performance airscrew, be characterized in: this propeller arrangement is reasonable in design, and preparation cost is moderate, stable performance, the speedup pattern structure that its blade surface is arranged has and promotes blade and to strike the function of ability, improves the driveability of screw propeller to a certain extent.
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.
