According to Fig. 5, the cross-sectional profiles 22 that described rudder blade section 20 down has a mirror-inverted.This cross-sectional profiles 22 from one by anterior hook-type convex shoulder 21 up to terminal convex shoulder 30, and begin to extend up to the area of profile thickness 23 conical expansion of a maximum.Connect an area 25 that extends towards terminal convex shoulder 30 on this frontal area 24, this area shrinks gradually towards terminal convex shoulder 30.Described frontal area 24 is divided into two area section 24a, 24b by one at rudder blade 100 vertical upwardly extending line of centers M2, and they are of different sizes.Bigger area section 24b be positioned at starboard side and less area section 24a towards port side.Rear portion area 25 is divided into two area section 25a, 25b by line of centers M2 equally.Here two area section 25a, 25b is equally big and be of similar shape.
Described two area section 24a, 24b in the screw propeller side that go up the cross-sectional profiles 22 of rudder blade section 20 have marginarium 26,26a, they have the beaming curve 26 ＇ a of smooth beaming curve 26 ＇ and a protuberance, wherein, two of the cross-sectional profiles 22 of following rudder blade section 20 are deviated from the area 25a of screw propeller 220, marginarium 27, the 27a that 25b has tangential extension.
The area section 24b of marginarium 26a with beaming curve 26 ＇ a of bigger protuberance is positioned at port side.
The structure and the layout of two rudder blade sections 10,20, make the outfit of going up rudder blade section 10 be positioned at port side with respect to line of centers M1 for the hook-type convex shoulder 11 of screw propeller 220, and the hook-type convex shoulder 21 of rudder blade section 20 is positioned at starboard side with respect to line of centers M2 down, and wherein two rudder blade section 10,20 Background Regions at rudder blade 100 are combined into a terminal convex shoulder 30.
According to Fig. 2 A, 2B, 3,4 and 5, two rudder blade sections 10,20 of described rudder blade 100 are by its cross-sectional profiles 12,22 so mutual settings, side and port side are positioned at the beaming curve 16 ＇ a of radian greatly of area section 14b and 24b and the rudder blade side wall sections in 26 ＇ a zones astarboard, the area section 14b of cross-sectional profiles 12 towards starboard side and the area section 24b of cross-sectional profiles 22 towards port side, therefore make the hook-type convex shoulder 11,21 of two rudder blade sections 10,20 be positioned at port side and starboard side.
But the present invention also comprises a kind of rudder for ship structure, according to this structure, two rudder blade sections 10,20 of described rudder blade 100 are by its cross-sectional profiles 12,22 so mutual settings, promptly in the zone of the beaming curve 16 ＇ a of the big radian of area section 14b and 24b and 26 ＇ a, be positioned at the side wall sections of the rudder blade of port side and starboard side, wherein, the area section 14b of cross-sectional profiles 12 towards port side and the area section 24b of cross-sectional profiles 22 towards starboard side, make the hook-type convex shoulder 11,21 of two rudder blade sections 10,20 be positioned at starboard side and port side.
In the rudder for ship structure shown in Fig. 6 to 8, represent a hull with 110, represent a rudder port bearing with 120, represent a rudder blade with 100, and represent a rudder stock with 140.A hinged fin keel 135 on rudder blade 100.Described rudder blade 100 has a best columniform hole 155, is used to hold the free end 120b of rudder port bearing 120.
Described rudder port bearing 120 is furnished with the inside slotted hole 125 at a center as cantilever beam, is used to hold the rudder stock 140 of rudder blade 100.Described in addition rudder port bearing 120 extend into rudder stock end bonded assembly rudder blade 100 in.Rudder port bearing 120 described in the hole 125 has a bearing 150 and is used to support rudder stock 140 within it, and wherein this bearing 150 is preferably disposed on the lower end region 120b of rudder port bearing 120.Described rudder stock 140 is outstanding from rudder port bearing 120 by an intercept 145 by its free end 140b.The free bottom that this of described rudder stock 140 prolongs intercept 145 reliably is connected at 170 places with rudder blade 100, but also stipulates a connection here, and in the time will changing prop shaft, it can make rudder blade 100 remove from rudder stock 140.At this rudder stock 140 170 places are positioned at prop shaft center 200 with being connected of rudder blade 100 above, therefore when the dismounting prop shaft, only need rudder blade 100 is taken off from rudder stock 140, and need not from rudder port bearing 120, to pull out rudder stock 140, because not only the free bottom of the free bottom 120b of rudder port bearing 120 but also rudder stock 140 all is positioned at top, prop shaft center.In the embodiment shown in Fig. 1 to 3, only be used at rudder port bearing 120 supporting rudder stocks 140 by a unique neck bearing 150; Saving another is used to make rudder blade 100 to be bearing in bearing on rudder port bearing 120 outer walls.In order to hold the free bottom 120b of rudder port bearing 120, described rudder blade 100 is furnished with a hole or a space with 160 expressions.
In rudder for ship, described rudder port bearing 120 is furnished with intracardiac slotted hole 125 in as cantilever beam, is used to hold the rudder stock 140 of rudder blade 100.Described in addition rudder port bearing 120 extend in the rudder blade 100 that is connected in the rudder stock end and has a bearing 150 in the hole 125 within it, is used for making rudder stock 140 to be bearing in rudder port bearing 120.Described rudder port bearing 120 extend in the space or hole 160 in the rudder blade 100 by its free end 120b, and wherein rudder stock 140 is outstanding from rudder port bearing 120 by an intercept 145 at its free end zone 140b.By this free end that prolongs intercept 145, described rudder stock 140 is connected with rudder blade 100, wherein rudder stock 140 be positioned at the prop shaft center being connected of rudder blade 100 above.In the 120b of the end of rudder port bearing 120, preferably has neck bearing 150.
The present invention is not limited to above-mentioned and embodiment illustrated in the accompanying drawings.The different schemes of the layout of bearing in rudder port bearing 120 and rudder stock 140 zones is the same with other structure of the cylindrical hole 160 in rudder blade 100, is located within the scope of the present invention equally.The rudder for ship structure that constitutes according to the present invention not only is used for boats and ships but also can be used for floating platform or allied equipment.
