Abstract
The present invention discloses a spoke blade propeller which relates to a propeller propulsion device. The spoke blade propeller is composed of a propeller blade, spokes and a propeller hub, wherein the propeller blade and the propeller hub are connected and fixed by the spokes. The spoke blade propeller is characterized in that the propeller blade and the spokes form a spoke blade structure. The maximum width of the side projection of the propeller blade is greater than the accumulated width of the side projections of the spokes. The spoke blade propeller has the advantages of high propulsion efficiency, small water power noise, good cavityperformance, etc., and is suitable for being used as a propulsion device for a ship.
Description
The present invention relates to a kind of ship propeller propelling unit.
The lateral projection of Modern Ships propeller blade is that the base is dropped on the propeller hub, and wedge angle is radially-protruding subtriangular.Its lateral projection's width is the width S between blade guide margin and the lagging edge, and maxim is arranged near blade root, reduces gradually to the blade tip direction.(1836) had a kind of screw propeller of fan-shaped blade in history, and its lateral projection is that minor face drops on the propeller hub, the radially-protruding rectangle in long limit.The lateral projection width of traditional propeller blade in little radius of rotation scope is big, and the lateral projection's width in the big radius of rotation scope is little and since blade area at the leaf waist to excessive the causing of blade root scope distribution proportion.This blade profile makes that traditional propeller efficient is lower, the waterpower noise big, the cavity poor performance.
The purpose of this invention is to provide a kind of propulsion coefficient height, the waterpower noise is little, the cavity performance is good a kind of screw propeller that the bar spoke is arranged.
The objective of the invention is by changing lateral projection's area distributions of traditional propeller blade, make the subtriangular lateral projection that stands on the propeller hub axis, turn around to become handstand on the propeller hub axis, lateral projection's figure radially wide at the top and narrow at the bottom, in order to improve maximum blade area distribution proportion to big radius of rotation interval, minimizing leaf waist to the blade area of blade root scope is realized.The present invention is made up of blade, bar spoke and propeller hub, it is characterized in that drawing one or more holes at traditional propeller blade leaf waist to the blade root interval, and remaining blade leaf waist to the part between blade tip is blade of the present invention, and it is distributed in maximum and big radius of rotation interval; Remaining blade leaf waist to the structure between blade root is of the present invention spoke, the bar spoke be blade with propeller hub between be connected and stationary member.It is characterized in that bar spoke and blade constitute unitized construction, blade leaf waist is littler to the maximum width in blade tip interval than leaf waist to the graphic width S of lateral projection in blade root interval, and promptly lateral projection's figure cumulative width of bar spoke is littler than blade lateral projection figure maximum width.The bar spoke can be shaft-like, camber beam shape, palisade or net structure, and has pitch surface.This pitch surface can be consistent with blade, also can be inconsistent with blade.The number of bar spoke with draw number of perforations and the position is relevant.
Draw a real hole to the blade root interval at traditional propeller blade leaf waist, obtain the unitized construction of two bar spokes constituting by guide margin and lagging edge; Draw two real holes, obtain the unitized construction of three bar spokes, its orthographic drawing as shown in Figure 1, the figure of its lateral projection is as shown in Figure 2; If draw a plurality of real holes brokenly, then obtain the unitized construction of netted spoke.
With three bar spoke broad ways accumulations in the unitized construction shown in Figure 2, obtain the equivalent lateral projection scheme drawing of a bar spoke, as shown in Figure 3; This is actual to be to draw two empty holes along guide margin and lagging edge to former blade thickness line direction, obtains the unitized construction of a bar spoke, its orthographic drawing as shown in Figure 4, the figure of its lateral projection is as shown in Figure 5.
The present invention can design and make by technical characterictic of the present invention, also can be formed by the traditional propeller transformation.The present invention can use iron, copper, aluminium and alloy thereof or plastic or other material manufacturing.
The present invention is owing to adopted the bar spoke and the unitized construction of blade formation, make lateral projection's figure cumulative width of bar spoke more much smaller than blade lateral projection figure maximum width, improved the area ratio of blade lateral projection relatively, thereby improved propulsion coefficient, reduced the waterpower noise, improved the cavity performance.Contrast through the preliminary test with Chu Side Type B three leaf on-hook screw propellers, propulsion coefficient is brought up to 0.7-0.75 by 0.5586.
Fig. 1 is the unitized construction orthogonal projection scheme drawing that three bar spokes are arranged;
Fig. 2 is the unitized construction lateral projection scheme drawing that three bar spokes are arranged;
Fig. 3 is the equivalent lateral projection scheme drawing after unitized construction shown in Figure 2 is accumulated three bar spoke width;
Fig. 4 is the unitized construction orthogonal projection scheme drawing that a bar spoke is arranged;
Fig. 5 is the unitized construction lateral projection scheme drawing that a bar spoke is arranged.
Below in conjunction with embodiment and accompanying drawing the present invention is elaborated:

After traditional propeller blade leaf waist 4 was drawn two real holes to blade root 6 intervals, remaining blade leaf waist 4 to the part of 5 of blade tips was blade 1 of the present invention; Remaining blade leaf waist 4 is of the present invention spoke 2 to the rod shaped structure of 6 of blade roots, bar spoke 2 are blades 1 with propeller hub 3 between be connected and stationary member.Bar spoke 2 is formed the unitized construction that three bar spokes are arranged with blade 1, its orthographic drawing as shown in Figure 1, the figure of its lateral projection is as shown in Figure 2.
Embodiment 2
Traditional propeller blade leaf waist 4 to blade root 6 intervals along guide margin and lagging edge after blade thickness line direction is drawn two empty holes, remaining blade leaf waist 4 to the part of 5 of blade tips is blade 1 of the present invention; Remaining blade leaf waist 4 to the rod shaped structure of 6 of blade roots is of the present invention spoke 2, bar spoke 2 are blades 1 with propeller hub 3 between be connected and stationary member, bar spoke 2 is formed the unitized construction that a bar spoke is arranged with blade 1, its orthographic drawing as shown in Figure 4, the figure of its lateral projection is as shown in Figure 5.
