Technical field
The present invention relates to marine machinery fields, are a kind of rotary blade type hydraulic steering gears peculiar to vessel integrated with rudder stock specifically.
Background technique
Rotary blade type hydraulic steering gear (hereinafter referred to as rotary-vane steering gear) is a kind of liquid driven by vane type oscillating motor body
Steering gear is pressed, has that small in size, light-weight, space occupied is small, easy to maintain, mechanical efficiency is high and consuming little energy etc. is excellent
Point, it is deep to be favored by shipowner and shipyard.Traditional rotary vane type steering gear generally includes the components such as stator, rotor, wherein rotor will be with
Rudder stock, which is formed, to be cooperatively connected, and transmits torque to rudder stock.This mode not only wastes material and process time, increases processing and dress
With difficulty, coaxiality error can be also formed between rotor inner hole and rudder stock, reduces the performance of rotary-vane steering gear.
The Chinese invention patent application of Publication No. CN102887221A discloses a kind of " Self-aligning rotary blade type liquid peculiar to vessel
Press steering engine ", bearing support cylinder is set outside hydraulic cylinder, bearing support cylinder includes bearing cylinder body and bearing cylinder seat, makes hydraulic cylinder and bearing support cylinder
Body constitutes spherical surface sliding pair, and hydraulic cylinder can deflect in bearing support cylinder body, so that automatic adjustment pushes away rudder rotor axis deviation.And by
In the obstruction for pushing away the limit tenon above rudder hydraulic cylinder and being supported cylinder body upper limit hole, makes to push away rudder hydraulic cylinder and bearing support cylinder keeps phase
To static, rudder hydraulic cylinder is pushed away when coming about will not follow pushing away the rotation of rudder rotor, so that rotary blade type hydraulic steering gear be made to work normally.The skill
Art scheme is adjusted the coaxiality error of generation by the way of increasing external structure, but can not be inherently eliminated same
Axis degree error, and part is increased, to improve cost of material, cost of manufacture, installation cost.
Summary of the invention
In order to solve the problems in the existing technology, the present invention provides a kind of rotary vane type hydraulic rudder integrated with rudder stock
Machine, with eliminate between existing rotary-vane steering gear rotor and rudder stock it is difficult to install, have the problem of coaxiality error.
The technical solution adopted by the present invention to solve the technical problems is: a kind of rotary vane type hydraulic rudder integrated with rudder stock
Machine, including cylinder body, upper cover plate, lower cover plate, stator vane, rudder stock, oil inlet and outlet, stator vane are located in cylinder body, upper cover plate and
Middle part, which is provided with rudder port, on lower cover plate rotate rudder stock be able to, and edge is provided with threaded hole, further includes rudder stock blade, the rudder stock
Blade is located at one end of rudder stock, and in the mounted state, one end that rudder stock does not set rudder stock blade passes through end-face seal ring, passes through lower cover
The rudder port of plate, cylinder body, which is covered, sets one end of rudder stock blade in rudder stock, lower cover plate is fixed on cylinder body with cover screw, set upper side
Face sealing ring, then upper cover plate is put on, upper cover plate is fixed on cylinder body with cover screw.
A kind of integrated rotary blade type hydraulic steering gear of above-mentioned and rudder stock, the stator vane and rudder stock blade it is each there are three,
It is evenly arranged in cylinder body and on rudder stock respectively.
The beneficial effects of the present invention are: traditional rotary-vane steering gear has a special rotor component, and rotary blade type liquid of the present invention
It presses steering engine to cancel rotor component, undertakes rotor function using rudder stock, both saved material and the process time of rotor in this way, and gone simultaneously
In addition to rotor is installed to the step on rudder stock, solves the problems, such as to be difficult to install between rudder stock and rotor, also eliminate rotor
The coaxiality error of inner hole and rudder stock.
Detailed description of the invention

Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to embodiment party of the present invention
Formula is described in further detail.
A kind of rotary blade type hydraulic steering gear integrated with rudder stock, including cylinder body 7, upper cover plate 2, lower cover plate 9, stator vane 8, rudder
Bar 5, oil inlet and outlet 6, stator vane 8 are located in cylinder body 7, and middle part, which is provided with rudder port, on upper cover plate 2 and lower cover plate 9 makes rudder stock 5
It is able to rotate, it further includes rudder stock blade 4 that edge, which is provided with threaded hole, and the rudder stock blade 4 is located at one end of rudder stock 5, in installation shape
Under state, one end that rudder stock 5 does not set rudder stock blade 4 passes through end-face seal ring 3, and across the rudder port of lower cover plate 9,7 sets of cylinder body in rudder
Bar 5 sets one end of rudder stock blade 4, and lower cover plate 9 is fixed on cylinder body 7 with cover screw 1, puts on end-face seal ring 3, then put on
Upper cover plate 2 is fixed on cylinder body 7 by upper cover plate 2 with cover screw 1.
Further, the stator vane 8 and rudder stock blade 4 it is each there are three, be evenly arranged in cylinder body 7 and on rudder stock 5 respectively.
The quantity of stator vane 8 and rudder stock blade 4 is also possible to other suitable quantity.
It is the overall structure diagram of rotary-vane steering gear as shown in Figure 1, the significant difference of the device and traditional rotary-vane steering gear is,
Traditional rotary-vane steering gear has special rotor component, and the present invention cancels rotor component, undertakes rotor function using rudder stock 5,
Material and the process time of rotor had both been saved in this way, while having eliminated step rotor being installed on rudder stock 5, solved rudder stock
It is difficult to the problem of installing between 5 and rotor, also eliminates the coaxiality error of rotor inner hole Yu rudder stock 5.Form rotary-vane steering gear
Hydraulic oil is housed, hydraulic oil is isolated into high-voltage oil cavity and low pressure oil by end face seal and runner sealing inside vane type tilting cylinder block
Chamber.Directly blade is installed on rudder stock 5, the hydraulic oil of high-voltage oil cavity acts on rudder stock blade 4, pushes rudder stock blade 4, rudder
Bar blade 4 drives rudder stock 5 to rotate；It can control 4 positive and negative rotation of rudder stock 5 and rudder stock blade by hydraulic system, to realize ship
Go to action.
It is the overall structure of the explosion figure of rotary-vane steering gear as shown in Figure 2, rudder stock 5 is fitted into cylinder body 7, guarantees rudder stock blade 4
With stator vane 8 in sustained height, two end-face seal rings 3 are then individually placed to 7 both ends of cylinder body, two cover boards pass through respectively
Cover screw 1 is fixedly connected with cylinder body 7, in this way without additional production rotor component, and undertakes rotor function using rudder stock.It is hydraulic
The high pressure oil that system provides enters inside cylinder body 7 from oil inlet 6, the sealing structure of cylinder body 7 by cylinder interior be divided into high pressure chest and
Low pressure chamber, high pressure oil, which acts on rudder stock blade, pushes rudder stock blade 4 to rotate, so that rudder stock be driven to rotate, realizes the steering of ship
Movement.
