Description
Technical field
The present invention relates to pump and use accessory field, particularly a kind of efficient light impeller shaft.
Background technique
The runner of institute's use water pump great majority adopt impeller at present, in use, promoting water by the blade on impeller flows out by water, the blade of impeller is gentlier affected by gravity just fewer, but because the mobile amplitude of current self is just larger, therefore the impact of the impeller to impeller is often large therefore high to the requirement of strength of blade, and blade do thin rear intensity will be significantly lower, therefore the very large contradiction of both existence, along with the continuous progress of science and technology, the continuous maturation of 3D printing technique, 3D printing technique has more and more applied in manufacturing industry, can use 3D printing technique preparation process to make blade and will in blade, make bar-shaped trough, to reduce leaf quality, but because blade and rotating shaft are that one-body molded such fabricating cost is very high.
Summary of the invention
For above problem, the present invention is a kind of efficient light impeller shaft, this efficient light impeller shaft main body is still used integral molding, but on each blade, be welded with by the reinforced blade that has bar-shaped trough structure in the moulding of 3D printing technique, so not only can ensure blade strength, and can greatly reduce leaf quality, and only having reinforced blade is to use 3D printing technique to make, therefore cost is also relatively cheap, for reaching this object, the invention provides a kind of efficient light impeller shaft, comprise fixed end, coupling shaft, main shaft, be connected and fixed portion, stator blade and reinforced blade, described main shaft two ends are connected and fixed portion, the described portion that is connected and fixed is connected with fixed end by coupling shaft, described stator blade tilts to be fixed on the cylndrical surface of main shaft, connecting place one side of the cylndrical surface of described stator blade and main shaft has a mounting groove, the reinforced blade main body of described reinforced blade is fixed end, described reinforced blade main body one side has bar-shaped trough, one end of described reinforced blade main body is fixed end, the fixed end of described reinforced blade main body is inserted in the bar-shaped trough of reinforced blade main body, described reinforced blade has a side of bar-shaped trough to be connected by welding manner with stator blade.
As a further improvement on the present invention, described reinforced blade is the reinforced blade of 3D printing technique moulding, and owing to being subject to the restriction such as width and shape, reinforced blade of the present invention is not there is no can only to use 3D printing technique to carry out moulding before better production method.
As a further improvement on the present invention, the bar-shaped trough of described reinforced blade main body one side has at least 2, forming V-shape discharge, one of the main purpose that the present invention arranges reinforced blade is to gain in strength, second is exactly to alleviate quality, consider discharged by the best forming V-shape of force intensity bar-shaped trough of the present invention, can keep so enough mechanical strengths.
As a further improvement on the present invention, the angle of described stator blade and alignment of shafts face is 30 °-60 °, and because blade too tilts, occupation of land is large and intensity is low.The little effect of blade lean is low, therefore should ensure that angle is 30 °-60 °.
As a further improvement on the present invention, the thick 0.5-1.5cm of described stator blade, due to the present invention, second half is stator blade, therefore vane thickness can only be 0.5-1.5cm.
As a further improvement on the present invention, the thick 0.4-0.8cm of described reinforced blade, realizes because reinforced blade of the present invention can use with 3D printing technique, and therefore thickness can be 0.4-0.8cm.
As a further improvement on the present invention, described bar shaped groove width 2-3cm, described bar shaped groove depth 0.2-0.3cm, is subject to width of blade and thickness is spacing, and it can only be above scope that the width of bar-shaped trough of the present invention enters with the degree of depth.
The present invention is a kind of efficient light impeller shaft, this efficient light impeller shaft, formed by main shaft and reinforced blade, on main shaft, there is blade to adopt integral molding foundry engieering to make, in reinforced blade, there is bar-shaped trough structure, be made by the moulding of 3D printing technique, weldering is attached on the blade of main shaft, like this under the blade of condition of equivalent thickness intensity, reinforced blade has bar-shaped trough structure therefore quality is relatively light due to interior, and the present invention only has reinforced blade to adopt the moulding of 3D printing technique to make therefore to compare cost with 3D global formation also relative cheap.
