Description
Technical field
The present invention relates to ship ' s equipment apparatus field, be specifically related to a kind of flexible wing flap rudder transmission device and flap type rudder thereof.
Background technology
Ship flap rudder, compared with general common streamline redder, when equal rudder area and oad, greatly can improve steerage (more than 40%), obtains the accreditation of more and more shipowner and adopt.Flap type rudder is made up of main rudder leaf and wing flap and secondary rudder blade, in the course of the work, secondary rudder blade is while moving along with main rudder leaf, and secondary rudder blade is produced and the autorotation in the same way of main rudder leaf rotation direction by transmission device for flap type rudder, with main rudder leaf become a relative angle, thus improve steerage.The transmission device of current flap type rudder mainly contains: gear type, guide rod type, crank-linkage type, rocker-arm, fork type etc.; and to use maximum be gear type and guide rod type; in recent years crank-linkage type due to the size of protective case little compared with gear type; and can by theoretical rudder blade line style value design; steerage is better, and light structure is easy to manufacture; cost is relatively lower, is accepted more and more and adopt by shipowner.In the past, the driving device of all flap type rudders was all be exposed in water, and burn into wearing and tearing are very fast, and great majority all change in the protective case of the sealing being arranged in rudder blade top now.Even so; due to the structural reason of transmission device; the protective case oad of gear type, fork type and crank-linkage type is all large than main rudder leaf moulded form value; particularly gear type; because oad is large; its offset can not design according to theoretical offset, causes the resistance of rudder blade to increase, and steerage reduces.The flap type rudder of current various band sealing protective; except seal protection is covered with sealing arrangement; other friction of motion parts are all still exposed in water; particularly secondary rudder stock and bearing, wearing and tearing are very fast, and the waters weighed in inland river and silt is particularly serious; within general 2 to three years, must bearing be changed and repair or change secondary rudder stock; this is the deficiency of current all flap type rudders, both there is potential safety hazard, turn increases the maintenance and repair cost of shipowner.
Summary of the invention
The present invention is directed to the deficiencies in the prior art; propose that a kind of size is little, transmission device is simple; stable working failure-free flexible wing flap rudder transmission device; and the oad of sealing protective can be reduced; main rudder leaf upper body can be directly utilized to establish sealing protective; thus reduce rudder blade resistance, improve the flap type rudder of steerage.Concrete technical scheme is as follows:
A kind of flexible wing flap rudder transmission device, comprise sun wheel (1) and satellite gear (2), described sun wheel (1) is fixed on lower bearing seat of rudder (3), described satellite gear (2) is fixed on secondary rudder stock (4), and the diameter of described sun wheel (1) is greater than satellite gear (2);
At least one driving band group (5) is provided with between described sun wheel (1) and satellite gear (2), this driving band group (5) is made up of the first driving band (51) and the second driving band (52), one end of wherein said first driving band (51) and the second driving band (52) is separately fixed in described sun wheel (1), the other end is separately fixed on described satellite gear (2), and described first driving band (51) and the second driving band (52) are parallel up and down and space crossed between described sun wheel (1) and satellite gear (2).
Principle of work of the present invention: in actual use, lower bearing seat of rudder is fixed on hull, secondary rudder blade is hinged on main rudder leaf by secondary rudder stock (4), main rudder leaf is connected with ship steering engine by rudder main stock, because the first driving band (51) and the second driving band (52) space level crossing between sun wheel (1) and satellite gear (2) is arranged, secondary rudder stock (4) with main rudder leaf while the running of sun wheel (1) center, because sun wheel (1) maintains static, satellite gear (2) generation one and identical the relatively rotating of main rudder leaf rotation direction will be made, thus drive secondary rudder stock and secondary rudder blade to rotate, make between secondary rudder blade and main rudder leaf, to form a relative angle, reach the transmission requirement of flap type rudder thus.Satellite gear (2) can not do 360 ° of rotations around the center of sun wheel (1), and the work of flap type rudder only need do ± 35 ° of rotations around the center of sun wheel (1), so satellite gear (2) can be that the operating angle enough meeting flap type rudder requires around the work anglec of rotation of sun wheel (1).
For realizing the present invention better, may further be:
Described sun wheel (1) and satellite gear (2) are even rows sprocket wheel, described driving band group (5) is made up of driving chain, one end wound clockwise of described first driving band (51) is fixed on the upper skate tooth of described satellite gear (2), and the other end wrapped anti-clockwise of this first driving band (51) is fixed on the upper skate tooth of described sun wheel (1); One end wrapped anti-clockwise of described second driving band (52) to be fixed under described satellite gear (2) on skate tooth, the other end wound clockwise of this second driving band (52) is fixed on the lower skate tooth of described sun wheel (1), and even rows sprocket wheel and semiclosed intersection chain form one group of complete intersection Chain conveyer.Adopt chain gear, structure is simple, and easy to maintenance, chain and sprocket wheel are connected firmly.
Flap type rudder in the present invention, comprise main rudder leaf (7), rudder main stock (6) and secondary rudder blade (8) and above-mentioned flexible wing flap rudder transmission device, described rudder main stock (6) is fixedly connected on the top of described main rudder leaf (7), described secondary rudder stock (4) is arranged on the upper rear of described main rudder leaf (7), the rudder pintle axle (9) corresponding with described secondary rudder stock (4) is provided with in the below of this main rudder leaf (7) afterbody, described secondary rudder blade (8) is hinged on the afterbody of described main rudder leaf (7) by secondary rudder stock (4) and rudder pintle axle (9), described sun wheel (1) and satellite gear (2) are arranged in the top of described main rudder leaf (7).In use, rudder main stock (6) rotates and main rudder leaf (7) and secondary rudder blade 8 will be driven around sun wheel center rotating, under the effect of flexible wing flap rudder transmission device, secondary rudder blade (8) is being followed while main rudder leaf (7) operates, produce relative rotation with identical rotation direction and main rudder leaf (7), make to produce a relative angle between secondary rudder blade (8) and main rudder leaf (7), meet the transmission requirement of flap type rudder thus.
May further be:
At described main rudder leaf (7) body upper part, protective case (10) is set; described flexible wing flap rudder transmission device is arranged in protective case (10); can flexible wing flap rudder transmission device be in the oil lubrication environment of sealing; effectively can prevent the erosion of silt, improve service life of transmission device and reliability and safety.
Beneficial effect of the present invention is: adopt driving band transmission to be Flexible Transmission, relative to other type of belt drive, its manufacture is easier, cost is lower, and installation, maintaining are simpler, especially adopts chain as driving band, be connected firmly, stable drive, easy to maintenance.Flexible wing flap rudder transmission device is hermetically sealed, all bearings and transmission device are all arranged in the oil lubrication environment of sealing, particularly secondary rudder stock rudder pintle axle and bearing, so not only can reduce the friction drag of motion, also greatly can reduce the wearing and tearing of bearing and movement parts, improve reliability and the service life of rudder gear.Chain conveyer required size is little, greatly can reduce the oad of sealing protective, thus lowers flap type rudder resistance, improves steerage.
