Description

Uppfinnare: H B Sedgfield Prioritet begard frdn den 25 augusti 1955 (Starbritannien) Denna uppfinning Haar sig till elektriskt drivna gyroskop. Inventor: H B Sedgfield Priority requested from 25 August 1955 (United Kingdom) This invention relates to electrically powered gyroscopes.

Ett av de problem, som foreligga vid elektriskt drivna gyroskop, är att det är nodvandigt att Ora en eller Fiera elektriska auslutning. artill ett kanselelement. Det vanliga shttet att astadkomma dessa anslutningar pa ar att anvanda slapringar, men dessa infora friktion. Ett alternativt salt, som ofta anvandes, dâ kanselelementet uppbares med begransad frihet till vinkelrorelse i ett foljeorgan, ãr att anordna bojliga tradforbindningar, vilka forbinda kanselelementet och foljeorganet med varandra, och att anvanda dessa bOjliga forbindningar sasoni stromforande ledare. Emellertid utova dessa bojliga forbindningar alltid nhgot vridmoment mellan kfinselelementet och fiiljeorganet, vilket vridmoment stor kanselelernentet. Ett betydande problem fir darfor, burn man skall konstruera dessa bOjliga forbindningar, sa att de utova minsta mojliga stOrande vridmoment pa kfinselelementet. One of the problems with electrically powered gyroscopes is that it is necessary to Ora one or Fiera electrical outlet. artill a pulpit element. The usual way to make these connections is to use slip rings, but these introduce friction. An alternative salt, which is often used when the pulpit element is supported with limited freedom of angular movement in a follower means, is to provide flexible wire connections, which connect the pulpit element and the follower member to each other, and to use these flexible connections as current-carrying conductors. However, these flexible connections always exert some torque between the lining element and the filing member, which torque is large in the chancel element. A significant problem for this reason is that these flexible connections must be designed in such a way that they exert the least possible large torque on the core element.

Ett satt, som har foreslagits for det fall, att kanselelementet ,ar monterat for rorelse omkring en svangaxel i ett foljeorgan, ãr att shsom bojlig forbindning anvanda en tunn rak metalltrad, vilken gar i en riktning, som Or vinkelrat mot svangaxeln, och Or forbunden med kanselelementet i en punkt pa svangaxeln eller nara denna. En vidareutveckling av detta siitt visas i det brittiska patentet 740 350. I gyroskopet enligt detta patent Or kfinselelementet monterat med frihet till vinkelr8relse relativt foljeorganet omkring tvâ mot varandra vinkelrata svangaxlar, vilka skara varandra i ett svangningscentrum, och bestar uppfinningen enligt patentet i anvandningen av bOjliga elektriska ledare, vilka direkt forbinda fOljeorganet och kanselelementet med varandra och vilka ha formeri av raka metalltra- vilka stracka sig i en riktning, som Or yinkelrat mot hada svangaxlarna, och Oro forbundna med kanselelementet vid eller nara svangningscentrum. I det i patentet visade gyroskopet befinner sig svangningscentrum i centrum av ett ror, vilket tjanar sasom en fast axel, omkring vilken rotorn roterar, och Oro de elektriska forbindningarna dragna axiellt genom detta ror. One method which has been proposed for the case that the pulpit element is mounted for movement about an axis of rotation in a follower means is to use as a flexible connection a thin straight metal wire which goes in a direction perpendicular to the axis of rotation and is connected with the pulpit element at a point on or near the pivot axis. A further development of this site is shown in British Patent 740,350. electrical conductors, which directly connect the follower member and the pulpit element to each other and which have the form of straight metal wires which extend in a direction which is perpendicular to the pivot axes, and Oro connected to the pulpit element at or near the center of oscillation. In the gyroscope shown in the patent, the center of oscillation is located in the center of a rudder, which serves as a fixed shaft, around which the rotor rotates, and the electrical connections are drawn axially through this rudder.

Vid de tidigare forslagen av den diskuterade typen liar den bojliga ledande traden eller metalltraden i den punkt, dar den at fast vid kfinselelementet, varit fastspand vid en fast del av kanselelementet. Vid upptradandet av relativ snedstallning mellan kanselelementet och foljeorganet uppstar da nodvandigtvis en svag homing av ledaren. Till fOljd av ledarens styvhet medfor denna bojning, att ett litet vridmoment utiivas mellan kanselelementet ()eh foljeorganet. Oavsett huru foljsamma ledarna gams, Or detta st5rande vridmoment av icke onskviird storlek for noggranna gyroskop. In the previous proposals of the type discussed, the flexible conductive wire or the metal wire at the point where it was attached to the lining element has been clamped to a fixed part of the pulpit element. When relatively oblique formation occurs between the pulpit element and the follower member, a weak homing of the conductor usually occurs. Due to the rigidity of the conductor, this bending means that a small torque is applied between the pulpit element () and the follower member. No matter how compliant the conductors are, this is a major torque of undesirable size for accurate gyroscopes.

Ett andamal med foreliggande nppfinning Or att astadkomma en gyroskopisk apparat av det angivna slaget, vid vilken den ledande traden ph nytt satt Or forbunden med kanselelementet. An object of the present invention is to provide a gyroscopic apparatus of the type indicated, in which the conductive wire is newly connected to the pulpit element.

Enligt foreliggande uppfinning liar astadkommits en elektrisk gyroskopisk apparat, innefattande ett gyroskopiskt stabiliserat kiinselelement, exempelvis den vertikala ringen en gyrokompass, vilket Or monterat i ett jeorgan med begransad frihet till yinkelriirelse oinking en foljeaxel relativt foljeorganet, och en anordning for ledning av elektrisk energi fran foljeorganet till kanselelementet, vilken anordning innefattar en bojlig ledande trh.d, som straAer sig vinkelratt mot axeln fran en punkt, dar den or fast vid foljeorganet, till en punkt i narheten av axeln, diir den halles i lage med avseende ph kanselelementet, kannetecknad darav, att anordningen for att halla traden i lage med avseende ph kanselelementet innefattar ett bojligt lagesbestammande organ, vilket Or fast vid kiinsel- 27 - elementet, stracker sig vinkelratt mot traden ocb tjanar till att halla den ledande traden sadant lage, att dess geometriska axel passerar genom foljeaxeln. According to the present invention there is provided an electric gyroscopic apparatus, comprising a gyroscopically stabilized lens element, for example the vertical ring a gyro compass, which Or is mounted in a limited freedom of movement relative to a follower axis relative to the follower means, and an electrically conductive means to the pulpit element, which device comprises a flexible conductive wire which extends perpendicular to the shaft from a point where it is fixed to the follower means, to a point near the shaft, where it is held in position with respect to the ph pulp element, drawn therefrom , that the device for keeping the wire in position with respect to the ph pulp element comprises a flexible layer determining means, which Or attached to the kiln element, extends perpendicular to the wire and serves to keep the conducting wire so low that its geometric axis passes through the foil shaft.

Embodiments of the invention will now be described with reference to the accompanying drawing, in which Fig. 1 is a schematic view of the vertical ring and follower member of a gyro compass according to an embodiment of the invention, Fig. 2 is a sehematic view of a gyroscopic apparatus. according to another embodiment of the invention, Fig. 3 is a sectional view on a larger scale through a part of Fig. 2, Fig. 4 shows a set for fastening a threaded arid a membrane and Fig. 5 is a sectional view through the bore in the fin element in Fig. 2.

I fig. 1 ar uppfinningen tillampad for Overforing av strom mellan ett foljeorgan 1 och en vertikal ring 2 i en .gyrokompass,. varvid den vertikala ringen 2 bildar kanselelementet. Detaljer hos gyrokompassen aro i&e visade, enfir de Oro obehiivliga for att uppfinningen skall forstks, men sadana detaljer kunna erhallas fran det brittiska patentet 707 446. Dimensionerna hos tradarna och deras barorgan relativt den vertikala ringen ha darjamte Overdrivits for tydlighets skull. In Fig. 1, the invention is applied to the transfer of current between a follower member 1 and a vertical ring 2 in a gyro compass. wherein the vertical ring 2 forms the pulpit element. Details of the gyro compass are shown in the drawings, which are not necessary for the invention to be understood, but such details can be obtained from British patent 707 446. The dimensions of the trades and their bar members relative to the vertical ring have also been exaggerated for the sake of clarity.

Del ma emellertid namnas, att den vertikala ringen uppbar ett rotorholje, som Or monterat med frihet till vinkelr5relse omkring en horisontell axel XY, vilken är vinkelrat mot den vertikala ringens vertikala axel RS, och att den i rotorholjet inneslutna rotorn utolires av en elektriskt driven rotor, som nodvandiggor att en elektrisk stromkalla anslutes till dess trefasmotor. F5r detta andamal Oro tre ledningar 3, 4, 5 anordnade, vilka aro inneslutna i ett gemensamt holje, vilket Or fast vid den vertikala ringen 2 medelst en klammer 6 och yid en U-formad forlangning 7 pa den vertikala ringen medelst en klammer 8. Ledningarnas 3, 4, 5 andar Oro ph den U-formade forlangningen 7 forbundna med andarna 9, 10, 11 pa tre b5jliga ledare 12, 13, 14, vilka stracka sig mellan den U-formade forlangningens 7 bada armar 15, 16. De bbjliga ledarnas andar 9, 10, 11 Oro monterade i armen 15 medelst isolerande pro.ppar 17, 18, vilka Oro fastklistrade i hal i armen. De bojliga ledarnas 12, 13, 14 andra andar aro likaledes monterade i isolerande proppar i forlangningens 7 andra arm 16, men i detta fall Oro nagra forbindningar iclie gjorda pit armens utsida. It must be mentioned, however, that the vertical ring carried a rotor housing mounted with freedom of angular movement about a horizontal axis XY, which is perpendicular to the vertical axis RS of the vertical ring, and that the rotor enclosed in the rotor housing is excreted by an electrically driven rotor. , as a matter of necessity that an electric current source be connected to its three-phase motor. For this purpose, three conduits 3, 4, 5 are provided, which are enclosed in a common housing, which is fixed to the vertical ring 2 by means of a clamp 6 and by a U-shaped extension 7 on the vertical ring by means of a clamp 8. The spirits of the wires 3, 4, 5 concern the U-shaped extension 7 connected to the spirits 9, 10, 11 on three flexible conductors 12, 13, 14, which extend between the two arms 15, 16 of the U-shaped extension 7. The spirits of the flexible conductors 9, 10, 11. The other spirits of the flexible conductors 12, 13, 14 are likewise mounted in insulating plugs in the second arm 16 of the extension 7, but in this case concern some connections made outside the outside of the pit arm.

Med de tre bojliga ledarnas 12, 13, 14 mittpunkter, vilka sammanfalla med den vertikala ringens vertikala axel, Oro tre primarledare 21, 22 forbundna, vilka stracka sig i en riktning, som Or vinkelrat mot de biijliga ledarnas langdriktning. Primarledarna Oro fiirbundna med de bojliga ledama pa nagot lampligt satt, exempelvis genom 18dning eller svetsning, och primarledarna liksom de bojliga ledarna kunna yarn gjorda av platina- trad, vilken Or isolerad medelst isolerande lack. Primarledarna 20, 21, 22 Oro i de fran fastpunkterna 23, 24, 25 vanda andarna fas- ta yid en obojlig skiva 27 av isolerande material, exempelvis bakelit, vilken Or fastskru- vad pa en hallare 26, som Or utformad sasom en del av foljeorganet 1. Dessa andar av primarledarna aro fasta vid skivan 27 medelst Ire stutsar 28, 29, 30, vilka Oro fastnitade Yid skivan, varvid tradarnas andar Oro fastlodda inuti stutsarna. Tradarnas andar kun- na sedan vara forbundna med en lamplig elektrisk stromkalla, exempelvis en trefasgenerator. With the center points of the three flexible conductors 12, 13, 14, which coincide with the vertical axis of the vertical ring, Oro connected three primary conductors 21, 22, which extend in a direction perpendicular to the longitudinal direction of the flexible conductors. The primary conductors are connected to the flexible conductors in a suitable manner, for example by welding or welding, and the primary conductors as well as the flexible conductors can be made of platinum wire, which is insulated by means of insulating varnish. The primary conductors 20, 21, 22 In the fixed points 23, 24, 25, the spirits attach to a rigid disc 27 of insulating material, for example bakelite, which is screwed onto a holder 26, which is formed as a part of the follower means 1. These spirits of the primary conductors are fixed to the disk 27 by means of Ire sockets 28, 29, 30, which Oro riveted the Yid disk, the spirits of the wires Oro being soldered inside the sockets. The spirits of the traders can then be connected to a suitable electric cold source, for example a three-phase generator.

Till fOljd av de bojliga ledarnas 12, 13, 14 bojlighet Or del vridmoment, som ut5vas pit kanselelementet 2 Over de b5jliga ledarna, nar relativ rotation forekommer mellan dem omkring as.eln RS, givetvis mycket mindre On del yridmoment, som skulle utovas, om primfirledarna yore stelt anslutna mellan f5ljeorganet 1 och punkter pa kanselelementet 2 i narheten av svangaxeln, sasom tidigare har foresl agit s. Due to the flexibility of the flexible conductors 12, 13, 14 Or part of the torque exerted by the pulpit element 2 Over the flexible conductors when relative rotation occurs between them about the axis RS, of course much less the primer conductors are rigidly connected between the follower member 1 and points on the pulpit element 2 near the pivot axis, as previously suggested.

Fiiretradesvis tillampas ett likadant arrangemang med avseende pa rotorholjets svang- axel XY i den vertikala ringen for ledning av strom fran ledningarna 3, 4, 5 till ledningar pa rotorholjet. Preferably, a similar arrangement is applied with respect to the pivot axis XY of the rotor housing in the vertical ring for conduction of current from lines 3, 4, 5 to lines on the rotor housing.

Det irises, att anordningen av tradarna skulle kunna omkastas, dvs. att sekundartra- darna 12, 13, 14 skulle kunna vara infasta mellan armarna pi ett U-format organ, vilket bildar del av foljeorganet, och ha sina mitt- punkter forbundna med primartradar, som stracka sig fran fastpunkter pa den vertikala ringen. It is irises that the arrangement of the trades could be reversed, i.e. that the secondary wires 12, 13, 14 could be attached between the arms of a U-shaped member, which forms part of the follower member, and have their midpoints connected to primary wires, which extend from fixed points on the vertical ring.

Del inses Oven att var och en av tradarna 12, 13, 14 skulle kunna ersattas med en myc- ket Mpg membran, varvid. primartradarna 20, 21, 22 skulle vara fasta vid membranernas centra. Membranerna skulk kunna vara monterade i borrningar i en vid organet 7 fast skiva av isolerande material och skulle kunna vara ledande eller oledande och iiverdrag- na med ledande material, som pa lampligt sOtt skulk vara anslutet till ledningarna 3, 4, 5 Yid membranernas periferier. Anvandning- en av membraner Or emellertid mera fOrdelaktig, da man onskar leda strom Iran fOljeorganet direkt till kfinselelementet, och sadan anvandning visas i fig. 2. It is also recognized that each of the trades 12, 13, 14 could be replaced with a large Mpg membrane, whereby. the primary lines 20, 21, 22 would be fixed at the centers of the membranes. The membranes could be mounted in bores in a plate of insulating material fixed to the member 7 and could be conductive or non-conductive and coated with conductive material, which should be suitably connected to the conduits 3, 4, 5 at the peripheries of the membranes. The use of membranes, however, is more advantageous, since it is desired to direct current from the follower member directly to the filter element, and such use is shown in Fig. 2.

Ett annat utforande av uppfinningen visas i fig. 2-5 pa ritningen. I dessa figurer visas en gyroskopisk apparat, som innefattar ett kanselelement 31, vilket bestar av en plattform, som uppbar tva icke visade rotorer, vil- ka Oro monterade for rotation i rotorholjen 32, 33, som Oro utforda i ett stycke med plattformen. Kanselelementet 31 Or pa valkant satt monterat med begransad frihet till vinkehilrelse omkring tva mot varandra vinkelrata axlar XY, RS, vilka aro vinkelrata mot rotorns rotationsaxel, relativt ett uppbarande fOlje- — —a organ 34 medelst en kardanring 35. Stopporgan (icke visade) begransa rOrelsen till en liten rorelse. Foljeorganet 34 är darjamte monterat med frihet till vinkelriirelse omkring tva. mot varandra vinkelrata axlar, vilka normalt befinna sig i linje med axlarna XY, RS i ett huvudbarorgaa (icke visat), och ar servoreglerat fOr rOrelse omkring dessa axlar medelst servomotorer (icke visade), som aktiveras frau avkannare (joke visade) for att folja kfinselelementets 31 vinkelrorelser omkring dess vridaxlar. En gyroskopisk apparat, som liar ett servoreglerat foljeorgan, ar allmant val kant burn facket och beh8ver icke beskrivas i detalj, emedan uppfinningens art kan Mit fOrstas utan sadan beskrivning. Another embodiment of the invention is shown in Figures 2-5 of the drawing. These figures show a gyroscopic apparatus comprising a pulpit element 31, which consists of a platform carrying two rotors (not shown), which Oro mounted for rotation in the rotor housing 32, 33, which Oro challenges in one piece with the platform. The pulpit element 31 Or on the selection edge is mounted with limited freedom of angular rotation about two mutually perpendicular axes XY, RS, which are perpendicular to the axis of rotation of the rotor, relative to a supporting follower member 34 by means of a gimbal ring 35. Stop means (not shown) limit the movement to a small movement. The follower member 34 is further mounted there with freedom of angular movement about two. axes perpendicular to each other, which are normally in line with the axes XY, RS in a main bar body (not shown), and are servo-regulated for movement about these axes by means of servomotors (not shown), which are activated from sensors (joke shown) to follow the angular motions of the fin element 31 about its axes of rotation. A gyroscopic apparatus, which has a servo-regulated follower, is generally selectable to burn the compartment and need not be described in detail, since the nature of the invention can be understood without such description.

Var och en av rotorerna drives av en elektrisk motor, och i fig. 2 visas tva ledningar 36, 37, vilka komma fran rotorholjets 32 inre. Tva primartradar 38, 39 Oro i sina yttre Ondar forbundna med fOljeorganet 34, och enligt uppfinningen aro dessa primartradar forbundna med ledningarna 36, 37 ph sadant satt, att (la tradarna 38, 39 Oro anslutna till en lamplig elektrisk stromkalla, strom kan ledas till motorn for drift av rotorn och ovasentligt vridmoment utovas p0. kanselelementet av tradarna. Each of the rotors is driven by an electric motor, and Fig. 2 shows two lines 36, 37, which come from the interior of the rotor housing 32. Two primary wires 38, 39 are connected in their outer wires to the follower means 34, and according to the invention these primary wires are connected to the wires 36, 37 ph so set that (let the wires 38, 39 the motor for operation of the rotor and insignificant torque are exerted on the pulpit element by the wires.

Sasom visas, är traden 38 forbunden med centrum a-v en bOjlig membran 40, vilken Or belagen pa kanselelementet nara skarningspunkten mellan axlarna och Or elektriskt forbunden med ledningen 36. Pa liknande salt Or traden 39 forbunden med centrum av en bojlig membran 41, vilken är belagen pa kanselelementet parallellt med den fOrstnamnda membranen men pa den motsatta sidan om axlarnas skarningspunkt och Or elektriskt fOrbunden med ledningen 37. Tva ledningar 42, 43 fran rotorholj et 33 Oro Oven elektriskt forbundna med membranerna 40, 41 (fig. 3), men dessa ledningar visas icke i fig. 2. Monteringen av tradarna 38, 39 pa membranerna och ftiljeorganet Or sadan, att tradarna Oro precis strama och stracka sig i riktningar, som ga genom axlarnas XY, RS skarningspunkt. As shown, the wire 38 is connected to the center of a flexible membrane 40, which is coated on the pulpit element near the point of intersection between the shafts and is electrically connected to the conduit 36. On similar salt, the wire 39 is connected to the center of a flexible membrane 41, which is coated on the pulpit element parallel to the first-mentioned diaphragm but on the opposite side of the axis of intersection of the shafts and Or electrically connected to the conduit 37. Two conduits 42, 43 from the rotor housing 33 Oro Above electrically connected to the diaphragms 40, 41 (Fig. 3), but these conduits is not shown in Fig. 2.

Vardera membranen Or gjord av tunt, b8jligt, oledande material, exempelvis terylen eller gummi, som pa ma sidan Or overdraget med en tunn belaggning av ledande material. Traden 38, vilken kan vara av platina, passerar genom membranen 40 och dess ledande belaggning och Or elektriskt forbunden med belaggningen medelst en rornit 44 av metall, vilken tjanar till att hâlla metalltraden i lage. I andamal att ftirbattra den elektriska forbindningen kan tradanden vara fastIodd. ROrniten Or deform.erad Over en tryckbricka 45. Each membrane is made of thin, flexible, non-conductive material, such as terylene or rubber, which on the other hand is coated with a thin coating of conductive material. The wire 38, which may be of platinum, passes through the membranes 40 and its conductive coating and is electrically connected to the coating by means of a metal runnite 44, which serves to keep the metal wire in place. In order to improve the electrical connection, the thread can be fixed. ROrniten Or deform.erad Over a pressure washer 45.

Membranen 40 Or fast vid en ihalig isolerande propp 46 medelst ett ledande ringformigt organ 51, som Or fastskruvat vid prop-pen.

Proppen 46 Or fast vid kOn- selelementet 31 medelst skruvar, av vilka tva 49, 50 visas, ph sadant satt, att proppen strOcker sig in i en borrning 52 i plattformen, varvid dess symmetrilinje passerar genom axlarnas XY, RS skarningspunkt. Borrningens tvarsektion visas i fig. 5. Kanaler 53, 54 arc anordnade, sâ att det aggregat, som bestar av propp, trad, membran och ledande organ 51 med ledningarna 36, 42 pa forhand fastlOdda pa armama 47, 48, kan insattas sasom en enhet i borrningen. The diaphragms 40 Or are fixed to a hollow insulating plug 46 by means of a conductive annular member 51, which Or is screwed to the plug. The annular member 51 has arms 47, 48, to which the conduits 36 and 42 may be soldered. The plug 46 is fixed to the connecting element 31 by means of screws, two of which 49, 50 are shown, so that the plug extends into a bore 52 in the platform, its line of symmetry passing through the intersection point of the shafts XY, RS. The transverse section of the bore is shown in Fig. 5. Channels 53, 54 are arranged so that the assembly consisting of plug, wire, membrane and conducting member 51 with the conduits 36, 42 pre-secured to the arms 47, 48 can be inserted as a unit in the borehole.

It will be appreciated that each diaphragm forms a bar device for a primary row and locates the fixed primary row thereby such that radial movement of the fixed point of the thread relative to the XY, RS axis of intersection is prevented, while angular movement of the thread and membranes about each diameter passing through the fixed point. , easily admitted. The result is that the relative angular movement between the follower member 34 and the pulpit element 31 takes place about the axes XY, RS, the torque exerted on the pulpit element by the electrical connection consisting of wire and membrane, or much less on the torque to be exerted, if the trade Yore kept connected in its spirit with the pulpit element near the intersection, as previously suggested.
