Abstract
The invention discloses a wear-resistant screw propeller comprising a screw propeller main body, a bushing, a plurality of blades, a cooling fin, a plurality of through holes, a sleeve cap, and a supporting rod. The bushing is arranged on the middle of the screw propeller main body. The sleeve cap is arranged on the top of the bushing. The through holes are provided on the surface of the sleeve cap. The cooling fin is arranged between the sleeve cap and the bushing. Three blades are arranged on the edge of the screw propeller main body. The supporting rod used for mounting is connected to the bottom of the screw propeller main body. With the structure, the wear-resistant screw propeller provided by the invention has the advantages of simple structure, high hardness, breakage prevention, and long service life.
Description
Technical field
The present invention relates to the component of machine field, particularly relate to a kind of anti abrasive screw propeller.
Background technology
Screw propeller is to depend on blade to rotate in air and turn of engine power is converted into the device of propulsive force or has two or more leaf to link to each other with hub, and the one side backward of leaf is for helical surface or be similar to a kind of ship propeller of helical surface.Screw propeller is divided into a variety of, use also very extensive, as aircraft, steamer etc.General screw propeller hardness is low, fractures easily, and service life is short.
Summary of the invention
The technical matters that the present invention mainly solves provides a kind of anti abrasive screw propeller, and is simple in structure, and the hardness height is not easy fracture, long service life.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of anti abrasive screw propeller is provided, comprise: screw propeller main body, axle sleeve, a plurality of blade, radiating gill, a plurality of through hole, upper shield and pole, be provided with axle sleeve in the middle of the described screw propeller main body, upper shield is equipped with at described axle sleeve top, described cover cap surface has through hole, radiating gill is housed in the middle of described upper shield and the axle sleeve, described screw propeller body rim is equipped with three blades, and the bottom of described screw propeller main body is connected with the pole that is used to install.
In a preferred embodiment of the present invention, described screw propeller main body and blade are made by high-carbon steel.
In a preferred embodiment of the present invention, described blade surface is sprayed with protective paint.
In a preferred embodiment of the present invention, pass through bolted connection between described screw propeller main body and the axle sleeve.
The invention has the beneficial effects as follows: a kind of anti abrasive screw propeller of the present invention, simple in structure, the hardness height is not easy fracture, long service life.
Description of drawings
Fig. 1 is the structural representation of a kind of anti abrasive screw propeller one preferred embodiment of the present invention;
The mark of each parts is as follows in the accompanying drawing: 1, through hole, 2, upper shield, 3, axle sleeve, 4, radiating gill, 5, the screw propeller main body, 6, blade, 7, pole.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby protection scope of the present invention is made more explicit defining so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that.
See also Fig. 1, a kind of anti abrasive screw propeller, comprise: screw propeller main body 5, axle sleeve 3, a plurality of blade 6, radiating gill 4, a plurality of through hole 1, upper shield 2 and pole 7, be provided with axle sleeve 3 in the middle of the described screw propeller main body 5, upper shield 2 is equipped with at described axle sleeve 3 tops, and described upper shield 2 surfaces have through hole 1, described upper shield 2 and the axle sleeve 3 middle radiating gills 4 that are equipped with, described screw propeller main body 5 edges are equipped with three blades 6, and the bottom of described screw propeller main body 5 is connected with the pole 7 that is used to install.
In addition, described screw propeller main body 5 and blade 6 are made by high-carbon steel, the hardness height, and toughness is strong, is not easy to fracture, and is wear-resistant.
In addition, described blade 6 surfaces are sprayed with protective paint, and protection screw propeller surface is not easy to produce cut, and is antirust anti-wear.
In addition, by bolted connection, screw propeller main body and axle sleeve are connected between described screw propeller main body 5 and the axle sleeve 3, drive unitary rotation after pole is installed.
Be different from prior art, a kind of anti abrasive screw propeller of the present invention, simple in structure, the hardness height is not easy fracture, long service life.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification sheets of the present invention and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
