Description
The present invention relates to a kind of adjustable spiral slurry (CFP=Controllable fixed propeller), the propeller hub that it has a single-piece or separates, the slurry hub slurry shaft connector of slurry hub by a cylinder or circular cone is fixed on the slurry axle, and its paddle is rotatably supported in corresponding to a limited setting range under the main operation situation of ship on the slurry hub: the present invention includes the bearing set of paddle in the slurry hub, accurate adjustment and fixedly paddle adjusting and stop motion mechnism and will regulate and handle energy and be delivered to the transport sector of starching hub from ship.
With can be corresponding to whole difference of rotating the roll adjustment spiral shell slurry (CPP=Controllable Pitch Propeller) of paddle with the reversing operating range forward, the main operation situation of navigating by water forward corresponding to ship, the present invention is provided with the adjusting and the correct equipment of navigation slurry distance forward, so that can mate slurry distance and propeller rotating speed economically, reach and effectively utilize machine power, adapt to the variation of hull effect.The reason that causes variation is because sea-crust, aging and mode of operation and sea state change, for example speed, draft, state of equilibrium change, or in the fluctuation of special interference, seawater with under special sailing conditions, as boat in river and frozen water.
No matter be for having whole advancing and the roll adjustment spiral shell slurry (CPP) of the steam circle that falls back, or scheme to hitherto known adjustable spiral shell slurry (CFP), they all adopt the slurry hub that is provided with circular port in hollow slurry hub inside, in order to the paddle step disk to be installed, on screw paddle step disk that the Chu Ye flange is fixing, so rotating bearing set is partly formed by the circle slurry nave collar that protrudes between paddle blade root and the step disk.In paddle step disk inboard groove is arranged usually, wherein, the adjusting beam is passed in stop and adjustment force by rotating slide block and pin.This is applicable to the whole slurry hub that advances and move backward setting range band paddle step disk, and direct regulating tank and the structure of regulating beam in the paddle axis, require the slurry hub to be designed to hollow body, it is connected with slurry axle, starches that hub slurry axle connects and power is passed to a part of regulating beam with flange or additional being used to.
When outer rim is packed in the hollow slurry hub as the paddle step disk of circle, require to have a corresponding big slurry hub end-face hole, to starch diameter relevant with spiral shell for it.
At known slurry hub with axle adopts taper or cylindrical pressure is connected and in this bonding pad in the suggestion of the position on paddle plane (DD-WP243479, DD-WP248334, DD-WP248335), the same requirement proposes the additional space demand to this paddle step disk, thereby slurry hub diameter and quality are increased.This have another shortcoming of the rotatable bearing set of paddle of paddle step disk and regulating tank to be on the paddle axis direction, because adjustment (adjusting) lever is contained in slurry hub inner chamber, its length limited system is so length is less, and change, so need bigger stop and adjustment force with the paddle turned position.Prove failure-free slurry hub and paddle bearing set in the roll adjustment spiral shell slurry of in the whole scope that moves forward and backward, working so far, be diverted in the structure design of adjustable spiral shell slurry.But diameter reduces and a paddle bearing set that significantly strengthens stop and adjustment force throw of lever is arranged, and still is the unknown with the scheme that is used for adjustable spiral shell slurry slurry hub.
Also more known other various open files, they are intended to simplify the fixed mechanism for the good slurry distance of adjusted, and reduce adjustment force.For example DD-WP200730 discloses a kind of adjusting beam that can be along the longitudinal movement between the paddle step disk, has processed one or several longitudinal slot of its oblique angle in the self-locking scope on it.Move stopping power and the adjustment force of regulating beam,, in ship, spread out of by a drive link that is contained in the propshaft that is drilled to hollow.
Paddle by the also known a kind of adjustable spiral shell slurry of DD-WP225400 is adjusted by means of the tensioning member that is fixed in the slurry hub, tensioning member is designed to longitudinally to act as and is designed to adjust on the adjusting beam of cylinder, and after unclamping force fit, can utilize heat effect to handle.Further the research back is found, adopts this scheme can not make paddle have enough accurate adjustments and failure-free to fix.
In addition, by known in the disclosed file, with usually to regulate energy by the slurry axle input that is drilled to hollow in roll adjustment spiral shell slurry different, it certain ask another kind of possibility, be about to handle or regulate energy is delivered to rotation from ship slurry axle or slurry hub.In these suggestions, or with machinery or with the control signal of electricity, pass to propeller non-rotary or rotation, at this moment, regulate in the energy of energy from be stored in the slurry hub and extract; Or, from rotating energy, produce by means of other devices such as gravity pendulums.Yet, do not make a kind of switch and transmitting element that enough reliability are arranged of merit so far, it can not increase maintenance load and aboard ship use for many years.In addition, in this system, additional operation element must be set, with control slurry distance (positioner).Actv. solution to this journey is not seen as yet.
DD-WP80634 proposes a kind ofly to transmit the device that energy is used for roll adjustment spiral shell slurry between ship and slurry hub, and it is made up of a continuous current excitation electromagnet and the ferromagnet that is contained in slurry hub side rigidity, and establishes an eddy-current disc or cage rotor.Utilize these systems to produce relative rotary motion between slurry hub and adjusting mechanism, this is for regulating slurry apart from necessary.The weak point of this system is, in order to regulate the slurry distance, must establish additional device, and this system is not suitable for the relatively short adjusting approach of enforcement, otherwise can cause the slippage of adjusting part transmission device.
The objective of the invention is to make a kind of adjustable spiral shell slurry, its advantage is, the first, and by reducing to starch the quality and the diameter of hub, make the slurry hub of thrust loss and a kind of comparable non-adjustable spiral shell slurry compare as far as possible little; The second, by the advance accuracy of any moment paddle accurate adjustment in the process of raising, make the spiral shell slurry can with the power parameter optimum matching of main frame; The 3rd, switch and transmitting element height reliability from energy is handled and regulated to ship to the slurry hub can not increase the maintenance load of using ship for many years.
Scheme also proposes a kind of propulsive mechanism together therewith, with it ship is worked economically, even also fuel consumption minimum, and, utilize machine power best, and make propulsive mechanism and available machine gross horsepower mate preferably cutting off auxiliary energy when consuming.Therefore can obtain one in short-term and realize the required bigger tractive power of higher ship's speed, as the speed of weighing anchor.
Therefore, task of the present invention is to propose a kind of adjustable pitch propeller, and its paddle is contained in the slurry hub with a kind of novel bearing set, compares with a kind of comparable roll adjustment spiral shell slurry, and slurry hub overall diameter is less, and the slurry hub diameter of starching corresponding to a kind of comparable non-adjustable spiral shell; In addition, by a kind of fixable stop and regulating mechanism accurate adjustment paddle of can being in harmonious proportion accurately, all stop moment and power are not all absorbed by this mechanism under the situation of external energy having in continuous firing on the paddle, it is less apart from institute's energy requirement to change slurry with this mechanism, and at any time all can carry out the controollable optimum adjustment.Task of the present invention also comprises, find a kind of way, can make manipulation and regulate energy and contactlessly import the slurry hub from ship with electromagnetism or permanent magnetic mode, and the hydraulic-slip loss that causes aspect the transmission device that can not occur regulating from paddle in the slurry hub, or the slurry that does not also need the paddle of adding is apart from control mechanism.
Finishing the measure that above-mentioned task takes by the present invention is, the paddle blade root that can rotate in the hub at slurry always couples together with a single-piece or discerptible paddle back plate limitedly, and paddle back plate and adjusting and truck dead lever are unified into one " paddle supporting regulating plate "; In slurry hub inside, outside the paddle bearing set location in the slurry hub, no matter be in the back or the front, particularly in the back, or in the slurry hub cap of a back, also can pack into one directly to rest on slurry hub, slurry hub prolongation or the slurry hub cap and also can axially movable anti-rotation regulate beam in a fwd slurry hub prolongation, it is by means of the lever engagement of adjusting cotter that can move in skewed slot and paddle supporting regulating plate; In addition, regulating beam utilizes screw connection to be connected with adjusting screw(rod) with adjusting cylinder or a stop that is contained in one heart in the adjusting beam with a stop of supporting in slurry hub cap or slurry hub prolongation rotationally, they then are contained in slurry hub, slurry hub prolongation or starch the high reduction ratio transmission device of the self-locking in the hub cap with one, are connected as worm gearing; The transmission device stepping finder parallel with the steerable of an electromagnetism or permanent magnetic and slurry axis cardinal principle links to each other, and stepping finder then contactlessly connects in work with an electromagnetism or a permanent pulsactor that is contained in un-rotatably on the hull.
Adopt a kind of like this energy delivery system, regulate, can obtain controlledly to supervise the advantage that paddle is regulated by the corner that makes the switch number of steps be proportional to paddle.
In the supporting area of paddle supporting regulating plate in the slurry hub, a non-circular profile is preferably arranged, profile as the side section, in this case, the face of its vertical main shaft and formation supporting, be in paddle master's load plane of advancing and producing when falling back, and lateral shaft is reduced to the diameter in the paddle blade root hole in the slurry hub always.The direction of paddle supporting regulating plate adjusting and locking lever is equally also consistent with vertical main shaft substantially.End at adjusting and truck dead lever, be provided with a pin or a groove that is applicable to installation pin or slide block, the length of lever arm of force should make it in whole control process greater than wide half of paddle supporting regulating plate degree or greater than paddle blade root radius, and can be in predetermined rotating in about 4 ° to 8 ° angle of regulation range.When adopting force fit in the design of slurry hub, the slurry hub can adopt all-in-one-piece, or is made up of in the back in this case interior ectoplasm hub, and paddle supporting regulating plate inboard is bearing on the entoplasm hub, its opposite side is bearing on the ectoplasm hub, and the radial support of paddle is realized by paddle blade root flange or centering ring.Paddle supporting regulating plate also can be designed to discerptible, and it also can bear the radial support task.
Preferably make the paddle blade root by centering disk and the centering of paddle supporting regulating plate, and be connected with barrel bolt by means of screw connection, make diametral load from the paddle blade root, directly or via the telophragma between paddle supporting regulating plate and centering ring or paddle blade root and the paddle supporting regulating plate, pass to the slurry hub.Centnifugal force, paddle moment of torsion, stop and adjustment force pass to the slurry hub from paddle supporting regulating plate.
Adopt in the version of pressing force fit in slurry hub and connecting of axle, the paddle plane is in the bonding pad of slurry hub and axle, and the bus of paddle is vertical, or backward towards slurry hub axis tilt one angle, this angle substantially with the slurry hub with spool cooperate coning angle suitable.Supporting under the situation of regulating plate with the paddle of the parallel installation of axle, adjusting cotter is columniform, under the bevelled situation, and design balling-up pin.If do not have adjusting cotter on the paddle supporting regulating plate, change and establish regulating tank, then can reduce stop and adjustment force degree of dip with respect to the slurry axis, for example be lower than 15-25 °.
Be with the difference of the disc type bearing set of using always in the roll adjustment spiral shell slurry,, slurry hub diameter is reduced, and for the limited setting range of angle, stop and adjustment (adjusting) lever be longer by narrower paddle supporting regulating plate of the present invention.(in above-mentioned accent spiral shell slurry, circular step disk radially lives paddle by its diameter and Rezessen surely, and it has determined the internal diameter and the assembling hole size of hollow slurry hub, and thereby has determined slurry hub external diameter.) according to the slurry hub with spool be connected.But according to structure or by the different schemes of the paddle of single-piece or split supporting regulating plate version with interior ectoplasm hub.The radial support of paddle utilizes paddle blade root flange, or supports regulating plate and centering ring or centering disk by paddle and realize.
According to paddle supporting regulating plate of the present invention, its transfer surface should be designed to, and in the power effect plane of advancing and moveing backward the maximal support width is arranged.Act on the power on the paddle supporting regulating plate downside, directly pass to slurry hub inside face.The length of the axial location of paddle mounting hole, paddle diameter and slurry hub inner bearing face should determine mutually like this that the common bigger load that produces during promptly to reversing also can be born reliably.Single-piece or discerptible paddle supporting regulating plate and adjustment (adjusting) lever and adjusting cotter or regulating tank constitute an assembly.Because the position of adjustment (adjusting) lever part can not be subjected to the restriction of paddle blade root radius so lever length does not resemble under the situation of the spiral shell slurry slurry hub that has step disk in the front or the back at paddle blade root position, and can be long, for example twice is so long.By making paddle supporting regulating plate have adjustment (adjusting) lever, adjusting cotter or regulating tank, and by means of they structure arrangements in the slurry hub, adjusting cotter can have a bigger diameter, and regulating tank can have a bigger width, so correspondingly just reduced load and wearing and tearing.
With being contained in rotating slide block is housed in the skewed slot on the adjusting cotter of paddle supporting regulating plate, they slide in skewed slot when regulating the beam side travel.The height and the width of sliding surface size and slide block should determine by the width and the shape of adjustment (adjusting) lever, make the adjustment (adjusting) lever can both free activity under various control positioies, and are limited on the final position.Because paddle supporting regulating plate lever is longer, and rotational force is directly passed to because of anti-then be bearing in adjusting beam on slurry hub, slurry hub prolongation or the slurry hub cap, and since tiltedly sliding tray form one as 15-25 ° acute angle with respect to the longitudinal axis, event makes fixing and regulates the power of starching distance and reduces for twice, is reduced to for example to be 1/6 of this power in the slurry hub of the compared roll adjustment spiral shell slurry of being with the paddle step disk.
Further reduce adjustment force by the present invention, can be by regulating beam and being rotatably supported in the stop on slurry axle, slurry hub, slurry hub prolongation or the slurry hub cap and regulating being threaded between cylinder or stop and the adjusting screw(rod) and realize.
By the present invention, the 4th time of power reduce to be by worm gearing and stop and adjusting cylinder or with being connected and disposing and realize of stop and adjusting screw(rod).
For again or the whole slurry of accurate adjustment distance, regulate cylinder or adjusting screw(rod) by slewing arrangement, according to the stroke of traction or push unit, rotates a structurally definite angle.This slewing arrangement is made up of worm gear, worm screw and single channel drive clutch, belongs to adjusting, preliminary election and slurry apart from indicating device.
In having the slewing arrangement of worm screw, pull bar or draw gear should be like this and the single channel drive clutch join, i.e. their switched in opposite, therefore slurry apart from increase or reduce will according to handle that pull bar come fixed.
In the device of forming by the adjusting knurl of band helical teeth or skewed slot,, can make adjusting screw(rod) rotate an angle of structurally determining to the left or to the right equally by correspondingly reversal dip and engagement of draw gear at that time.
Traction or the push unit of regulating usefulness can move to slurry hub front end face district always in the slurry hub that adjustable spiral shell is starched, and use under the flange bonded assembly situation at slurry hub and axle, arrive the slurry shaft flange end towards hull or screw shaft pipe outlet or propeler bracket always.Two draw geares all can couple together to opposite permanent magnet with the utmost point at this end of slurry hub or this end of slurry shaft flange, make them under the spring force effect, transfixion or moving to travelling backwards.Lid by the water shutoff and the oil sealing of non-magnetic material system is set at the slurry hub or at slurry on the shaft flange, the axial motion of permanent magnet and draw gear is guaranteed at the adjusting work that carries out in service that has under the situation of reliable protection at ship.
In addition; on hull or tail slurry hub or propeler bracket, fixedly mounted an electromagnet apparatus that not rotatable integral body maybe can be divided by the present invention; it is installed corresponding to the axial location of spiral shell slurry or slurry axle rear flange; by a gap; cover permanent magnet with a discontiguous distance, to replace the rear portion of rope fender guard and/or stern tube seal system.
During continuous firing, no current in the electromagnet apparatus.Revert by suitable selection material or polarity and to make remanent magnetism less.For corrosion prevention, pourable resin in the coil, device seals with non-magnetic material towards that side of spiral shell slurry.
Electric energy is imported in ship, utilize a preliminary election and read out instrument change direction of current increasing or reduce to starch distance, and the prescribed switch number of steps is also shown under direction at that time, this slurry at that time also can be realized under various rotating speeds, at this moment apart from realizing under left alone without help car state, by means of at that time direction of current in coil, by the permanent magnet groups that magnetic field suction and direction of current match, other then be ostracised, or stay the initial position.The design parameters of permanent magnet and electromagnet apparatus can be starched size, adjustment force with spiral shell and external electric current and voltage intensity is complementary.
By selecting the dead center position of driving device, force transfering device and permanent magnet device, make the initial tractive force of draw gear less, the terminal tractive force increases, or the initial manipulation of push unit is reduced with the terminal actuating force that reduces more energetically.
To then to install two pairs or many at the ship place one side permanent magnet of packing into to making axially movable permanent magnet with respect to the slurry axle.Each is to always comprising the permanent magnet of two reversals.
At dead center position, two magnet shift out beyond their action plane.If will regulate paddle, then according to regulating direction, make one in these magnet to move in the radio plane of flow, that is in the slurry hub.During the rotation of slurry hub, as the situation in electromagnet, the permanent magnet in the slurry hub is always passed in the magnetive attraction pulse, thereby has implemented adjusting.Reversing sense is regulated and is undertaken by the magnet arrangement of conversion in that side of ship.
The spiral shell slurry also can be adjusted by the magnet that repeatedly moves axially (pulsation rhythmically) shipboard when dead ship condition.
The principle of work and the structure design principle of adjustable spiral shell slurry are such, when ship reaches an arbitrary stable forward travel state, behind ship's speed, thrust, moment of torsion and the rotating speed that at this moment record is reached, under the mode of operation unmodified situation of ship and machine with small step for example ± 0.05 ° or 0.1 ° be adjusted to bigger or less slurry distance, change the slurry distance apart from ground by this small step, can find out immediately in machine constant in energy or the accurate respective change of thrust when constant, and provide the direction of seeking optimum value.The slurry that regulates is lived by secure fixation during doing the boatman.So can not carry out autonomous adjustment.With unmodified slurry apart from period, do not infeed and regulate or the stop energy to the spiral shell slurry, do not have the mechanical friction contact of regulating mechanism moving parts, so this structure helps reducing the wearing and tearing when the life period of ship uses yet.
In order to readjust into a bigger or less slurry distance, respectively there is one to change circuit that separates separately and the transfer device that direction of current is used.Connect in two circuit one each time corresponding to direction of current, just connect in each circuit, make slurry,, reduce or increase an identical amount as 0.05 ° or 0.1 ° apart from by regulating step pitch.Afterwards, the slurry that regulates that this is new is apart from being fixed once more.With a preselector, a plurality of adjusting step pitches are carried out automatically continuously, so the corresponding increase of regulating degree.Connect situation by automatic record, can indicate paddle position at that time, and thereby can repeat some adjusting.
Though the paddle back plate special bearing set of structure design by can rotate limitedly of adjustable spiral shell slurry is resulting slurry hub diameter big than non-adjustable spiral shell slurry.But less than a kind of comparable roll adjustment spiral shell slurry.Different with roll adjustment spiral shell slurry, paddle is contained in the bonding pad of slurry hub and axle, and adjustment (adjusting) lever is longer, has reduced paddle stop and adjustment force.Act on the transverse force on the paddle supporting regulating plate pin, directly pass to slurry hub, slurry hub prolongation or slurry hub cap by regulating beam and skewed slot.Remaining axial retention and adjustment force are reduced to approximately 1/3 again by 15-25 ° the skewed slot of tilting approximately, so compare with roll adjustment spiral shell slurry, because long lever and skewed slot are arranged, remaining stop and adjustment force reduce to about 1/6.
Adjustable spiral shell slurry of the present invention can be made into prototype.Or spiral shell slurry axle is not done retrofiting under the structural change situation used.
