Abstract
Description
503 426 10 15 20 25 30 35 2 perspektivvy i större skala, delvis i snitt av denna dubbla kardanknut. 503 426 10 15 20 25 30 35 2 perspective view on a larger scale, partly in section of this double gimbal.
Den pá ritningarna visade konstruktionen utgör ett exempel pá lösning av problemet att kombinera propellrar med ställbara propellerblad med en böjlig propelleraxel.The construction shown in the drawings is an example of a solution to the problem of combining propellers with adjustable propeller blades with a flexible propeller shaft.
Denna propelleraxel 1 består i det visade utförandet av två delar 2,3. Delen 2 är ansluten till en icke visad drivmotor och är kopplad till ena sidan av en dubbel kardanknut 4, som vid sin motsatta sida är sammankopplad med delen 3, vilken är förbunden med ett propellernav 5 med ställbara propellerblad 6. Anslutningen till drivmotorn har i fig. 1 visats i förenklad form med ett drev 7, som star i ingrepp med ett vid propelleraxeln 1 fast anbragt kugghjul 8.This propeller shaft 1 consists in the embodiment shown of two parts 2,3. The part 2 is connected to a drive motor (not shown) and is connected to one side by a double universal joint 4, which at its opposite side is connected to the part 3, which is connected to a propeller hub 5 with adjustable propeller blades 6. The connection to the drive motor has in fig. 1 is shown in simplified form with a gear 7 which engages a gear 8 fixedly attached to the propeller shaft 1.
I det visade utförandet har antagits att propeller- drivorganet 5 är inställbart med hjälp av ett tryckmedium.In the embodiment shown, it has been assumed that the propeller drive means 5 is adjustable by means of a pressure medium.
Härför löper genom propelleraxeln 1 en böjlig tillförsel- ledning 9 och en böjlig returledning 10 från en regler- ventil 11 till var sin i propellerdrivorganet 5 anordnad svivel 12, 13, vilka leder tryckmedium vidare till icke visade reglerdon för vridning av propellerbladen 6 pá i och för sig känt sätt. Lämpligen sträcker sig, sásom visat, ledningen 9 koaxiellt genom ledningen 10.For this purpose, a flexible supply line 9 and a flexible return line 10 run through the propeller shaft 1 from a control valve 11 to each swivel 12, 13 arranged in the propeller drive means, which lead pressure medium on to control devices (not shown) for rotating the propeller blades 6 on and off. known manner. Suitably, as shown, the conduit 9 extends coaxially through the conduit 10.
Vid det visade utförandet av uppfinningen sträcker sig vidare genom propelleraxelns 1 del 2 ett rör 14 mellan en endast antydd konsol 15 och den dubbla kardanknutens 4 leder 16 och 17 pá dess ena sida. Fran kardanknutens 4 leder 18, 19 pà dess motsatta sida sträcker sig ett andra rör 20 genom propelleraxelns 1 del 3 in i propellerdriv- organet 5 och vilar i ett lager 21 i detta.In the embodiment of the invention shown, a tube 14 extends further through the part 2 of the propeller shaft 1 between a bracket 15 only indicated and the joints 16 and 17 of the double universal joint 4 on its one side. From the joints 18, 19 of the universal joint 4, on its opposite side, a second tube 20 extends through the part 3 of the propeller shaft 1 into the propeller drive member 5 and rests in a bearing 21 therein.
Varje dubbel kardanled 16, 17 resp. 18 19 är vridbar kring ett sfäriskt lager 22 (endast ett visat i fig 2).Each double universal joint 16, 17 resp. 18 19 is rotatable about a spherical bearing 22 (only one shown in Fig. 2).
Genom ett hál 23 i kardanknuten 4 sträcker sig mellan båda rören 14 och 20 ett rörstycke 24. Vid var ände är detta rörstycke 24 utformat med ett par mittemot varandra belägna tungor 25, som sträcker sig in i rörets 20 (resp. 14) ände i det sfäriska lagret 22. Tungorna 25 utgör för- 10 15 20 25 30 35 503 426 3 längningar av rörstycket 24 och är anbragta vid ledtappar 26 (endast en visad i fig. 2), som är belägna vid lagrets 22 tänkta centrumlinje 27.Extending between a tube 23 in the universal joint 4 between the two tubes 14 and 20 is a pipe section 24. At each end this pipe section 24 is formed with a pair of opposite tongues 25, which extend into the end of the pipe 20 (resp. 14) in the spherical bearing 22. The tongues 25 form extensions of the pipe piece 24 and are arranged at pivot pins 26 (only one shown in Fig. 2), which are located at the imaginary center line 27 of the bearing 22.
Rören 14 och 20 och det dem förbindande rörstycket 24 utgör en fast, d v s ovridbar del i konstruktionen.The pipes 14 and 20 and the pipe piece 24 connecting them form a fixed, i.e. non-rotatable part in the construction.
Ledningarna 9 och 10 sträcker sig koaxiellt genom röret 14, rörstycket 24 och röret 20, och dessa delar sträcker sig i sin tur koaxeillt genom hela propelleraxeln 1.The lines 9 and 10 extend coaxially through the tube 14, the pipe piece 24 and the tube 20, and these parts in turn extend coaxially through the entire propeller shaft 1.
Med en propelleraxel 1 konstruerad pá beskrivet sätt har man möjlighet att under drift svänga delen 3 i pilens 28 eller pilens 29 riktning för att åstadkomma girar hos en marin farkost, samtidigt som propellerbladen 6 är ställbara för vinkeländring eller för omslag frán fram till back eller vice versa.With a propeller shaft 1 constructed in the manner described, it is possible during operation to pivot the part 3 in the direction of the arrow 28 or the arrow 29 to produce gears in a marine vessel, while the propeller blades 6 are adjustable for angular change or for turning from back to back or vice versa.
Uppfinningen är icke begränsad till det visade och beskrivna utförandet utan kan varieras pà många olika sätt inom ramen för efterföljande patentkrav. Ledningarna 9 och 10 kan sålunda lika väl förlöpa parallellt inne i rören 14 och 20 och rörstycket 24 eller utgöras av borrade kanaler.The invention is not limited to the embodiment shown and described but can be varied in many different ways within the scope of the appended claims. The lines 9 and 10 can thus just as well run parallel inside the pipes 14 and 20 and the pipe section 24 or consist of drilled channels.
Propellerbladen 6 kan i stället styras pneumatiskt eller elektriskt, i vilket sistnämda fall ledningarna 9 och 10 ersättes med kablar.The propeller blades 6 can instead be controlled pneumatically or electrically, in which latter case the lines 9 and 10 are replaced by cables.
Ledtappen 26 kan vara anbragt i ett i rörstyckets 24 längdriktning sig sträckande ovalt hal för upptagande av längdtoleranser under propelleraxelns 1 vridning och samtidiga utsvängning av delen 3.The guide pin 26 can be arranged in an oval hall extending in the longitudinal direction of the pipe section 24 for accommodating length tolerances during the rotation of the propeller shaft 1 and simultaneous pivoting out of the part 3.
Alternativt kan det visade utförandet med ledtappen 26 ersättas med en kardanknut av den typ, som utnyttjas vid exempelvis en kompassgyro eller jordglob, d v s en kardanknut med öppet centrum. Härigenom kan en propul- sionsanordning inställas i vinkellägen, som avviker fràn propelleraxelns 1 centrumlinje även i vertikalplanet.Alternatively, the embodiment shown with the guide pin 26 can be replaced with a universal joint of the type used in, for example, a compass gyro or globe, i.e. a universal joint with an open center. As a result, a propulsion device can be set in angular positions which deviate from the center line of the propeller shaft 1 also in the vertical plane.
