Description
(1) technical field
What the present invention relates to is a kind of propelling unit or steering gear of boats and ships.The driving device that specifically a kind of watercraft rudder/wing rudder jointly controls.
(2) background technology
The wing of two identical aspect ratios, equal chord length, under identical angle of attack condition, the crooked wing comparison with camber claims the section wing to have bigger lift coefficient, this is because the effect of camber is equivalent to increase the angle of attack.Rudder/wing rudder is that rudder is divided into main rudder and two parts of wing rudder by a certain percentage, makes by driving device to produce an angle between main rudder and the wing rudder, is actually a general streamline redder is become a rudder with certain camber.From broadly, wing rudder is equivalent to the wing of variable camber, before incoming flow separates, can provide bigger lift when identical main rudder angle, has improved the maneuvering performance and the seakeeping performance on naval vessel greatly.Simultaneously, when being in zero position, whole fin (rudder) presents the symmetry machine wing section again, reduces resistance, the navigation stability when guaranteeing the naval vessel direct route, so the research of the hydrodynamic performance of wing rudder and control, shaped design more and more causes the attention of shipbuilding circles.
Driving device between main rudder and the wing rudder has various ways such as guide rod type, chute-type, hinge type and oscillating rod type usually.The popular feature of these drivings device is to have fixing corner ratio between main rudder and the wing rudder, and promptly the rotational angle of wing rudder becomes fixed proportion with the rotational angle of main rudder, and wing rudder can't break away from the restriction of main rudder and freely rotate.Compare with common symmetric section rudder, have fixedly that the rudder/wing rudder of corner ratio has improved the power control performance, but because corner ratio fixing, wing rudder can't break away from main rudder and freely rotate, and makes the raising of boats and ships controller performance receive restriction.
(3) summary of the invention
The object of the present invention is to provide a kind of boat helm that can make generation any rotation angle ratio between rudder and the wing rudder, improve the boats and ships controller performance.
The object of the present invention is achieved like this:
It comprises by support 44, rack-mount outer frame 17, be installed in the base 19 on the outer frame, be installed in the support section that intermediate support plate 23 on the base and top base 24 and loam cake 29 are formed, last covering spindle motor 34 is installed, harmonic speed reducer 26 is installed between intermediate support plate and the loam cake, the output of spindle motor links to each other with harmonic speed reducer, main shaft driving gear 21 is installed on the output shaft of harmonic speed reducer, the main shaft driving gear is meshed with main shaft ring gear 42 on being fixed on main helm axis 2, the main shaft ring gear is installed on the main helm axis 2, the outer supporting neck bearing 13 that has of main helm axis, outer bearing 15, scroll bar electric machine assembly 16 and turbine sleeve 14, main rudder leaf 1 is installed on the main helm axis, harmonic speed reducer drives the scroll bar electric machine assembly that is fixed together with the turbine sleeve, the scroll bar electric machine assembly links to each other with wing rudder driven gear 10 by the turbine sleeve, wing rudder driven gear 10 be meshed with wing rudder driven gear 8 that wing rudderpost 7 is fixed together, wing rudder blade 5 is installed on the wing rudderpost, the top of main helm axis connects photoelectric code disk 39, and the below of wing rudderpost connects photoelectric code disk 3.
The present invention can also comprise some architectural features like this:
1, wing rudderpost 7 passes main rudder leaf 1 and is fixed together with wing rudder driven gear 8.
2, described photoelectric code disk 39 is fixed on by on the screw 40 top fixed code-disc supporting covers 35, and is linked to each other with main helm axis 2 by code-disc shaft coupling 37.
3, connection photoelectric code disk 3 in the below of described wing rudderpost is that wing rudderpost 7 links to each other with the photoelectric code disk 3 that is fixed on the main rudder leaf 1 with screw 4.
Principle of work of the present invention is:
During spindle motor 34 clickwises, it rotates by behind harmonic speed reducer 26, main shaft driving gear 21 and the main shaft ring gear 42, and main shaft 2 is rotated counterclockwise, and promptly main rudder leaf 1 rotates counterclockwise at this moment; Do not rotate if connect the motor of scroll bar in the scroll bar electric machine assembly 16 this moment, be that turbine sleeve 14 does not rotate, because wing rudderpost 7 passes main rudder leaf 1 and is fixed together with wing rudder driven gear 8, so wing rudder blade will clockwise rotate this moment, the angle of rotation and main rudder leaf 1 rotational angle are proportional; If when main shaft 2 rotates counterclockwise, make the motor rotation that connects scroll bar in the scroll bar electric machine assembly 16, be that turbine sleeve 14 drives 8 rotations of wing rudder driven gear to a certain direction, because wing rudderpost 7 passes main rudder leaf 1 and is fixed together with wing rudder driven gear 8, then can continue on wing rudder blade 5 original rotational angles increases or reduces rotational angle, makes the rotation of wing rudder blade 5 break away from the restriction of main rudder leaf 1.
When spindle motor 34 does not rotate, if make the motor rotation that connects scroll bar in the scroll bar electric machine assembly 16, be that turbine sleeve 14 drives 8 rotations of wing rudder driven gear to a certain direction, because wing rudderpost 7 passes main rudder leaf 1 and is fixed together with wing rudder driven gear 8, then wing rudder blade 5 can rotate under the static situation of main rudder leaf 1, also makes the rotation of wing rudder blade 5 break away from the restriction of main rudder leaf 1.
Main course of action of the present invention is as follows:
1, spindle motor 34 drives harmonic speed reducer 26 and main shaft driving gear 21, and main shaft driving gear 21 drives the main shaft ring gear U42 that is fixed on the main helm axis U2, the rotation of the main rudder leaf of Shi Xianing like this.
2, the scroll bar electric machine assembly 16 that is fixed together of driven by motor and turbine sleeve 14, scroll bar electric machine assembly 16 drives the wing rudder driven gear 8 that is fixed together with wing rudderpost U7, the rotation of the wing rudder blade of Shi Xianing like this.
3, the rotation of main helm axis 2 is isolated mutually with the rotation of scroll bar electric machine assembly 16 by neck bearing 13 and outer bearing 15 and is independent of each other, by having realized main helm axis 2 and scroll bar electric machine assembly 16 rotation directions and cooperating of rotational angle any rotation angle ratio of main rudder with wing rudder.
Major advantage of the present invention is embodied in: the rudder/wing rudder driving device with any rotation angle ratio makes the rotation of wing rudder can break away from the restriction of main rudder, the little control surface that is equivalent to a relatively independent motion of increase on rudder obviously improves the rudder hydrodynamic performance, thereby improves rudder system course controller performance.Use this driving device, under the design sea condition, the control of boats and ships can mainly be finished by the motion of wing rudder, owing to reduce the main rudder motion amplitude, makes energy consumption reduce, and reliability improves; When ship's navigation is being higher than design during sea condition, but the control main rudder of boats and ships and the Union Movement of wing rudder finish, thereby improved the navigability of boats and ships.
