Detailed description of the invention

The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.

With reference to Fig. 2,3, yacht fin stabilizer fin assembly of the present utility model is made up of fin axle 10, fin 12, flange body 13, key 14 and connecting bolt 15.During connection with by fin moulding process requirement is pre-, the lower flange 11 of fin axle 10 end is embedded in that fin 12 is internal and upper flange 31 near root surface Board position is along straight end-face key 14 to mutually tightly fitting, this key is arranged along fin chord length direction, it is internal that laminating rear flange sinks to fin 12 completely, now tightens connecting bolt 15.For ease of installing, key 14 is respectively adopted proper engagement and excessive fit form 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, it is ensured that fin 12 is with fin axle 10 synchronous axial system.The Flange joint technology of this miniaturization, only needs bolt to connect, it is achieved that the simple purpose installed, and keeps the line style that fin 12 primary light is suitable, beautifies profile and improve fluid property to a certain extent.Additionally it has breakthrough on fin axle 10 material selects, use precipitation-hardening thing stainless steel material, it has the features such as corrosion resistance and good, intensity height and good welding performance, natural corrosion resistance is effectively prevented fin axle and is corroded because being immersed directly in sea water, yield strength is about 2 times of tradition fin shaft material, reducing the physical dimension of fin axle or even actuator to a certain extent, good welding performance improves the processing technique 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 cloth angle settingα.Due to this bolt group mainly by the moment M of 0yz plane, i.e. along the thickness direction of fin 12, therefore in the case of installing space allows, bolt should be arranged in the thickness of fin 12 or on thickness direction, bolt cloth angle setting α is the least, and force-bearing situation is the best；Diameter of bolt d and bolt circle D also directly affects its force-bearing situation, and diameter d and D is all proportional with force-bearing situation.

With reference to Fig. 5, nonmetallic composite type fin 12 is made up of the glass fibre fin wing 21, the flange body 13 of steel, glass fibre skeleton 22 and polyurethane filler 23 etc., wherein the fin wing 21 is divided into upper half fin leaf shell and lower half fin leaf shell, every half structure includes structure sheaf, anticorrosive coat and gel coating resin the most successively, its thickness is than about 6:1:1, structure sheaf is main stress layer, anticorrosive coat ensures good corrosion resistance, gel coating resin provides the appearance that fairing is attractive in appearance, the molding the most in a mold of each Rotating fields, wouldn't the demoulding.Glass fibre skeleton 22 comprises some horizontal strokes, vertical skeleton, for the main support component of fin.Flange body 13 is made up of upper flange 31 and long axle sleeve 32, and long axle sleeve 32 makes flange body 13 be deeply inserted fin to ending, but is first not inserted into.By upper half fin leaf and skeleton, lower half fin leaf and skeleton and upper and lower fin leaf junction high-strength structure glue bond, now fin intralobar part forms a cavity.Upper half fin leaf shell is opened the fabrication hole of a 20mm, now requires to insert cavity by flange body 13 opsition dependent, inject density by placingJi Shu toward intracavity and be only 80kg/m³And there is the polyurethane filler 23 of rapid expanding and curing characteristics.The demoulding again after solidifying in fin phyllocyst etc. implant, at circular hole, fiberglass strengthens.Solid polyurethane is securely by upper and lower fin leaf shell, skeleton and Flange joint together.Comparing with tradition fin, this utility model has 2 obvious advantages, and one is only 1.8X103kg/m because of nonmetallic composite average density³(about the 25% of steel density), can alleviate weight effectively, and its two moulding process each fin leaf layer passing through uniqueness is strictly controlled by mould, improves fin line type precision, is prone to mass simultaneously, and manufacturing cost reduces, and glass fibre has natural corrosion resistance in addition.

With reference to Fig. 6, it it is the traditional fin lightweight packages comparison diagram under this utility model and equal fin area.Owing in this utility model, fin uses (except steel flange) low-density nonmetallic composite to make, which dictates that it is much smaller than traditional form at fin and fin lightweight packages, it is about the 46% of traditional form, this checking this utility model effect in terms of loss of weight is notable, and the fin assembly of lightness can better adapt to the feature of yacht stabilizer.
