Abstract
The utility model discloses a wear-resistant propeller which comprises a propeller body, a shaft sleeve, a plurality of blades, a cooling fin, a plurality of through holes, a sleeve cover and a support rod, wherein the shaft sleeve is arranged in the middle of the propeller body; the sleeve cover is arranged at the top of the shaft sleeve; the through holes are formed in the surface of the sleeve cover; the cooling fin is mounted between the sleeve cover and the shaft sleeve; three blades are arranged on the edge of the propeller body; and the support rod used for installation is connected to the bottom of the propeller body. According to the manner, the wear-resistant propeller is simple in structure, high in hardness, not prone to be broken and long in service life.
Description
Technical field
The utility model relates to the component of machine field, particularly relates 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 backward one side 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, such as aircraft, steamer etc.General screw propeller hardness is low, fractures easily, and service life is short.
The utility model content
The technical matters that the utility model mainly solves provides a kind of anti abrasive screw propeller, and is simple in structure, and hardness is high, is not easy fracture, long service life.
For solving the problems of the technologies described above, the technical scheme that the utility model 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 for the pole of installing.
In preferred embodiment of the utility model, described screw propeller main body and blade are made by high-carbon steel.
In preferred embodiment of the utility model, described blade surface is sprayed with protective paint.
In preferred embodiment of the utility model, be bolted between described screw propeller main body and the axle sleeve.
The beneficial effects of the utility model are: a kind of anti abrasive screw propeller of the utility model, simple in structure, hardness is high, 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 utility model;
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 utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
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 for the pole 7 of installing.
In addition, described screw propeller main body 5 and blade 6 are made by high-carbon steel, and hardness is high, 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, be bolted between described screw propeller main body 5 and the axle sleeve 3, screw propeller main body and axle sleeve are connected, drive unitary rotation after pole is installed.
Be different from prior art, a kind of anti abrasive screw propeller of the utility model, simple in structure, hardness is high, is not easy fracture, long service life.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification sheets and accompanying drawing content to do; 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 utility model.
