Abstract
The rudder for water craft comprises a rudder blade with a fin articulated thereto and a propeller associated with the rudder and located on a drivable propeller shaft. The rudder stock for the rudder blade is mounted in a central inner longitudinal bore of the rudder port bearing constructed as a cantilever beam by means of an inner bearing, the rudder port bearing having an outer bearing on its outer wall surface for mounting the rudder blade on the rudder port bearing.
Description
The present invention relates to a kind of rudder, especially for the spade balanced rudder of boats and ships.The fin that it has a rudder blade and connects with rudder blade, the screw propeller that is installed on the drivable oar axle is adjacent with it.
Particularly have in the occasion of spade balanced rudder of fin in use, the supporting member of rudder is passed to very large moment of flexure of hull, this moment of flexure is from suffered the making a concerted effort of rudder, this masterpiece is used on rudder-support socket or the rudder support tube, add the required moment of control vane, this biaxial stress situation has determined near the cross section pattern of the rudder stock of rudder-support socket, the size of support unit, the size of rudder blade and rudder stock junction and rudder blade profile thickness.
As everyone knows, the spade balanced rudder that good flow dynamic characteristic is arranged, particularly be added with the efficient spade balanced rudder of leading fin or tail fin, often be installed in casting and/or be welded in the rudder-support socket on the stern, rudder-support socket generally is positioned on the tuck branch, or be positioned at flat top, or be positioned at the tail fin that is fixed in hull.
In the occasion of hanging under the rudder body portion, moment of flexure is born by the rudder post with the hull connection, but very large rudder uses different support apparatus.
In a kind of rudder of known fixable type, a telescopic rudder-support socket is arranged to hold rudder stock on the hull, rudder stock extend in the rudder blade, rudder blade is made up of the horizontal metal thin plate that studs with the side direction metal sheet that multi-disc has certain intervals, the rudder stock that stretches in the rudder blade connects firmly by welding and rudder blade, so rudder stock can absorb torque and moment of flexure.
Have the moment of flexure that the mode of construction of support unit of the spade balanced rudder of tail fin produces rudder and reach rudder-support socket, and bear by rudder stock, so just must use very thick rudder stock, large scale for rudder stock and support unit thereof requires the widely-used of spade balanced rudder with tail fin placed restrictions on, and this situation occurs on the ship with about 15000 tons of load-carrying abilitys.
The separation of the biaxial stress state of hanging rudder is directed at disadvantageous asymmetrical characteristic on the fluid dynamics under this part, this be since rudder post be fixed on the top and occur in below the result of the interval effect on the balancing plane movably.Because screw propeller is released the current of rotation, the rudder square often is very asymmetric, so control vane need be used the maneuvering device than high-power.
Rudder with " base " supporting has very big shortcoming, and promptly wake flow distributes to the adverse effect that the position produced and the appendage drag increase of screw propeller.
At rudder, the veneer or the compound plate spade balanced rudder that particularly have fin, the problem to be solved in the present invention is: by designing a kind of special rudder-support socket, directly absorb a part in the rudder position and can reach the moment of flexure that rudder-support socket reaches hull again by rudder stock, this absorption has reduced rudder stock stress, can use thinner rudder stock and the simple purpose of connecting of rudder to reach.Another problem that the present invention will solve is: steer to be built in a kind of like this mode-to need not rudder stock is extracted out with regard to detachable prop shaft in rudder-support socket.
According to the present invention, the method for dealing with problems is that aforesaid rudder is built in this mode, i.e. rudder-support socket
A) be constructed to a kind of form of cantilever beam, longitudinal center's endoporus wherein arranged holding the rudder stock that has rudder blade,
B) extend in the rudder blade that connects firmly with the rudder stock end,
C) in the hole rudder stock block bearing is housed within it,
D) the rudder blade block bearing is housed with fixing rudder blade on its outer wall, the height of the block bearing in its height and the endoporus is roughly the same,
And the rudder stock lower end that is arranged in rudder blade is positioned near the propeller axis or above it.
Two of the method for dealing with problems is rudder-support sockets of aforementioned rudder
A) be constructed to a kind of form of cantilever beam, longitudinal center's endoporus wherein arranged holding the rudder stock that has rudder blade,
B) extend in the rudder blade that connects firmly with the rudder stock end,
C) in the hole rudder stock block bearing is housed within it,
D) its free end extend in the groove in the rudder blade,
And the part of rudder stock lower end is stretched out rudder-support socket, and this part of rudder blade and rudder stock connects firmly, and this junction is positioned at the propeller axis top.
First embodiment has provided such possibility, the telescopic bind mode of a kind of rudder and rudder-support socket promptly can be arranged, can also make the adjacent maneuvering device of rudder stock, a rudder stock block bearing is set for this purpose to mount rudder stock in rudder-support socket, also can several such block bearings be installed along rudder stock.
So on the quarter, can build such rudder, rudder-support socket is extend in the rudder blade as much as possible, if half of going into to stretch to meet or exceed the rudder blade height will produce obvious superiority by the technology of existing construction and processing.
Progressive of the present invention is: now the range of use to spade balanced rudder that tail fin is arranged increases greatly, and such tail fin adopts by the size of actual rudder usually and separates or unseparated form.By the separation of biaxial stress state, the rudder-support socket absorption that moment of flexure is extend in the rudder is passed on the hull then, and the staring torque of rudder can transmit by long rudder stock.Under the situation that does not change the rudder physical dimension, can use the thin section aerofoil profile that resistance is reduced.If consider and manufacture price and installation, this combination of rudder and rudder stock is more favourable.This solution has brought the possibility that reduces cost and price is installed also for undersized rudder-support socket.Moment of flexure can make the support unit minification with the result that torque separates, because they no longer stand severe buckling strain and stress.
Further embodiment has provided such preceence: because rudder stock only is that the block bearing that is positioned in the rudder-support socket lower end mounts, the part of its lower end stretches out rudder-support socket and rudder blade is fixed, this junction is positioned at the propeller axis top, and the parts of other supporting rudder blade need be installed on the rudder-support socket outside face.So, if pull down prop shaft,, need not rudder stock is taken out from rudder-support socket, because rudder blade and rudder stock junction are positioned at oar axle top as long as pull down rudder blade earlier.
