Description
Technical field
The present invention relates to marine machinery field, is a kind of rotary blade type hydraulic steering gear peculiar to vessel integrated with rudder stock specifically.
Background technology
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, light-weight, space 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 parts such as stator, rotor, wherein, rotor will be with
Rudder stock, which is formed, to be connected, and transmits torque to rudder stock.This mode not only process and fill by waste of materials and process time, increase
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 supporting cylinder body and supporting cylinder seat, makes hydraulic cylinder and bearing support cylinder
Body forms sphere sliding pair, and hydraulic cylinder can deflect in bearing support cylinder body, and rudder rotor axis off normal is pushed away so as to automatically adjust.And by
In the obstruction for pushing away the spacing tenon above rudder hydraulic cylinder and being supported cylinder body upper limit hole, make to push away rudder hydraulic cylinder and bearing support cylinder keeps phase
Pushed away to static, when coming about rudder hydraulic cylinder will not follow push away rudder rotor rotation so that rotary blade type hydraulic steering gear work normally.The skill
Art scheme is adjusted the coaxiality error of generation by the way of external structure is increased, but can not be inherently eliminated same
Axis degree error, and part is added, so as to improve cost of material, cost of manufacture, installation cost.
The content 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, 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 makes rudder stock to rotate, 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, through lower cover
The rudder port of plate, cylinder body are sleeved on one end that rudder stock sets rudder stock blade, lower cover are 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.
The rotary blade type hydraulic steering gear that a kind of above-mentioned and rudder stock integrates, stator vane and the rudder stock blade respectively have three,
It is distributed on respectively in cylinder body and on rudder stock.
The beneficial effects of the invention are as follows：Traditional rotary-vane steering gear has a special rotor component, and rotary blade type liquid of the present invention
Press steering engine to cancel rotor component, undertake rotor function using rudder stock, so both saved material and the process time of rotor, and gone at the same time
Except step rotor being installed on rudder stock, solve the problems, such as to be difficult to installation between rudder stock and rotor, also eliminate rotor
The coaxiality error of endoporus and rudder stock.

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 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 9 makes rudder stock 5
It is able to rotate, edge is provided with threaded hole, further includes rudder stock blade 4, 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 through the rudder port of lower cover 9, cylinder body 7 is sleeved on rudder
Bar 5 sets one end of rudder stock blade 4, and lower cover 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 respectively have three, are distributed on respectively in cylinder body 7 and on rudder stock 5.
The quantity of stator vane 8 and rudder stock blade 4 can also be 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, and rotor function is undertaken using rudder stock 5,
Material and the process time of rotor had so both been saved, while has eliminated step rotor being installed on rudder stock 5, has solved rudder stock
The problem of being difficult to installation between 5 and rotor, also eliminates the coaxiality error of rotor inner hole and rudder stock 5.Form rotary-vane steering gear
Hydraulic oil is housed inside vane type tilting cylinder block, hydraulic oil is isolated into high-voltage oil cavity and low pressure oil by end face seal and runner sealing
Chamber.Directly blade is installed on rudder stock 5, the hydraulic oil of high-voltage oil cavity is acted on rudder stock blade 4, promotes rudder stock blade 4, rudder
Bar blade 4 drives rudder stock 5 to rotate；4 rotating of rudder stock 5 and rudder stock blade can be controlled by hydraulic system, so as to fulfill 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, ensures 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, so without additionally making rotor component, and undertakes rotor function using rudder stock.Hydraulic pressure
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 is acted on rudder stock blade, promotes rudder stock blade 4 to rotate, so as to drive rudder stock to rotate, realizes the steering of ship
Action.
