Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
With reference to Fig. 2,3, yacht fin stabilizer fin assembly of the present invention is made up of fin axle 10, fin 12, flange body 13, key 14 and tie bolt 15.During connection by the lower flange 11 of fin axle 10 end be embedded in fin 12 in advance by the requirement of fin forming process inner and near the upper flange 31 of root surface Board position along straight end-face key 14 to mutually tightly fitting, this key is arranged along fin chord length direction, it is inner that laminating rear flange sinks to fin 12 completely, now tightens tie bolt 15.For ease of installing, key 14 adopts proper engagement and excessive fit form respectively with the side keyway of lower flange 11 and upper flange 31, and key is pre-installed on upper flange 31.During work, turn fin moment of torsion by key 14 transmission, ensure that fin 12 is with fin axle 10 synchronous axial system.The Flange joint technology of this miniaturization, only needs bolt to connect, achieves the object of simple and easy installation, keeps the line style that fin 12 primary light is suitable, beautifies profile and improve fluid property to a certain extent.Have breakthrough on fin axle 10 Material selec-tion in addition, adopt precipitation hardening thing stainless steel material, it has the features such as the high and good welding performance of corrosion resistance and good, intensity, natural corrosion stability prevents fin axle to be corroded because directly soaking in the seawater effectively, yield strength is about 2 times of traditional fin shaft material, reduce the scantling of structure of fin axle and even actuating unit to a certain extent, good welding performance improves the processing technology of fin axle upper flange.
With reference to Fig. 4, Flange joint mainly considers following geometric parameter: diameter of bolt d, bolt circle D and bolt arrangement angle
α.Because this bolt group is mainly subject to the moment M of 0yz plane, namely along the thickness direction of fin 12, therefore when installing space allows, bolt should be arranged in the thickness of fin 12 or on thickness direction, α is less at bolt arrangement angle, and force-bearing situation is better; Diameter of bolt d and bolt circle D also directly affects its force-bearing situation, and diameter d and D are all proportional with force-bearing situation.
With reference to Fig. 5, nonmetallic composite type fin 12 is made up of the flange body 13 of the glass fibre fin wing 21, steel, glass fibre skeleton 22 and polyurethane filler 23 etc., wherein the fin wing 21 is divided into first fin leaf shell and second fin leaf shell, every half structure comprises Structural layer, preservative coat and gel coating resin from inside to outside successively, its Thickness Ratio is about 6:1:1, Structural layer is main stress layer, preservative coat ensures good corrosion stability, the appearance that gel coating resin provides fairing attractive in appearance, each Rotating fields is shaping all in a mold, wouldn't the demoulding.Glass fibre skeleton 22 comprises some horizontal strokes, vertical skeleton, is the main support component of fin.Flange body 13 overlaps 32 by upper flange 31 and major axis and forms, and major axis cover 32 makes flange body 13 embed fin dearly to ending, but does not first insert.By first fin leaf and skeleton, second fin leaf and skeleton and upper and lower fin leaf junction high-strength structure glue bond, now fin interlobar part forms a cavity.First fin leaf shell is opened the auxiliary hole of a 20mm, now flange body 13 opsition dependent is required to insert cavity, in chamber, inject density by placingJi Shu and be only 80kg/m
3and there is the polyurethane filler 23 of rapid expanding and curing characteristics.The demoulding again after solidifying in fin phyllocyst Deng weighting material, strengthens at circular hole place glass-felt plastic.Solid polyurethane securely by upper and lower fin leaf shell, skeleton and Flange joint together.Compare with traditional fin, the present invention has 2 obvious advantages, and one is only 1.8X103kg/m because of nonmetallic composite average density
3(being about 25% of steel density), can expendable weight effectively, it two is strictly controlled by mould by unique forming process each fin leaf layer, and improve fin line type precision, be easy to mass simultaneously, manufacturing cost reduces, and glass fibre has natural corrosion stability in addition.
With reference to Fig. 6, it is the traditional fin lightweight packages comparison diagram under the present invention and equal fin area.Because fin in the present invention adopts (except steel flange) low-density nonmetallic composite to make, which dictates that it at fin and fin lightweight packages much smaller than traditional form, be about 46% of traditional form, this checking the present invention Be very effective in loss of weight, the fin assembly of lightness can adapt to the feature of yacht stabilizer better.
