Description

BESKRIVNING Uppfinningen avser en transmission for vindmotorer. DESCRIPTION The invention relates to a transmission for wind engines.

Som bekant utgores en vindmotor av en vinddriven rotor och en transmisslon for OverfOring av rotorns rorelse till en forbrukare. As is well known, a wind motor consists of a wind-driven rotor and a transmission for transmitting the rotation of the rotor to a consumer.

Transmissionen är nOdvandig darfor att rotorn van- ligen finns pa betydande hojd Over den pa marken placerade fbrbrukaren och darfoT Att rotorns vinkelhastighet och vridmoment i allmdnhet ar oldmplig fOr fOrbrukaren, som krgver hogre vinkelhastighet och ldgre moment dn rotorn normalt 10 ger. The transmission is necessary because the rotor is usually at a significant height above the ground placed on the ground and therefore the angular speed and torque of the rotor are generally unsuitable for the consumer, who requires higher angular velocity and lower torque than the rotor normally gives.

Dessa transmissioner, som forbinder rotorn med fOrbrukaren pa sadant satt, att avstandet mellan dem Overbryggas och det onskade utYIxlingsforhallandet mellan dem ernas, In for ngrvarande av mekanisk typ och innefattar 15 ett antal mellanaxlar forbundna medelst par av koniska kugghjul savd1 som av reduktionsvaxlar och/eller hastighetsvariatorer. These transmissions, which connect the rotor to the consumer in such a way that the distance between them is bridged and the desired gear ratio between them, are currently of a mechanical type and comprise a number of intermediate shafts connected by pairs of bevel gears sawn as by reduction shafts and / or speed variators.

Dessa transmisiener har olika tekniska nackdelar, sdrskilt buller, vibration, hoga underhallskostnader och 20 lag verkningsgrad. These transmissions have various technical disadvantages, especially noise, vibration, high maintenance costs and low efficiency.

Uppfinningen avser at:A 18sa detta problem genom att skapa en transmission med sadana konstruktiva och funktionella egenskaper, att de ovannamnda olagenheterna med teknikens standpunkt elimineras. Detta problem loses med 25 en transmission, som innefattar en av rotorn driven pump, inrdttad att avge en tryckfluiestrom, och en med tryckfluidstrommen matad fiuidmotor, som dr anordnad att rotera och i sin tur driva forbrukaren. The invention aims to: A 18sa this problem by creating a transmission with such constructive and functional properties, that the above-mentioned illegality units with the state of the art are eliminated. This problem is solved by a transmission which comprises a pump driven by the rotor, arranged to deliver a pressure fluid stream, and a fluid motor supplied with the pressure fluid stream, which is arranged to rotate and in turn drive the consumer.

Andra kanneteckcn och fordelar med transmissionen 30 enligt uppfinningen framgar av f8ljande beskrivning av en utforingsform, vilken anges som ett icke begransande exempel, under hanvisning till den bifogade ritningen, som visar en vindmctor med en transmission enligt uppfinningen. Other features and advantages of the transmission 30 according to the invention will become apparent from the following description of an embodiment, which is given by way of non-limiting example, with reference to the accompanying drawing, which shows a wind turbine with a transmission according to the invention.

Ledningarna 11, 12 ar fOrsedda med en roterande fordelare 14 av kdnd typ, som gör det mojligt for tornet 6 att vtida sig pA stativet 7 utan att det behOvs speciella 20 ledningar, t.ex. slangar. The lines 11, 12 are provided with a rotary distributor 14 of the kdnd type, which makes it possible for the tower 6 to turn on the frame 7 without the need for special lines, e.g. hoses.

Transmissionen innefattar ocksa en behallare for fluiden, som foretrddesvis är en for olKdynamiska kretsar lamclig olja, och en krets 16 for uppratthallande av ett fOrutbestdmt tryck i returledningen 12. Denna krets 25 inbegriper en liten hjdlppump 17, som drivs av rotorns 2 axel 5 genom en varvtalsmultiplikator 18 av kant slag, foretrddesvis med ett utvaxlingsforhallande av 10:1. The transmission also comprises a container for the fluid, which is preferably an oil for oil dynamic circuits, and a circuit 16 for maintaining a predetermined pressure in the return line 12. This circuit 25 comprises a small auxiliary pump 17, which is driven by the shaft 5 of the rotor 2 through a speed multiplier 18 of edge type, preferably with a gear ratio of 10: 1.

Pumpen 17 tar in fluid frail behallaren 15 genom en ledning 19 och driver in den i returledningen 12 genom 30 en ledning 20. Kretsen 16 innehaller Oven en tryekregler- ventil 21, som an ansluten till ledningen 12 och instdlld pa ett fOrutbestamt tryck. The pump 17 takes in fluid from the container 15 through a line 19 and drives it into the return line 12 through a line 20. The circuit 16 also contains a pressure control valve 21, which is connected to the line 12 and set at a predetermined pressure.

Ledningarna 11, 12 farbinds av en sdkerhetsventil 22, som sltpper genom fluiden fran ledningen 11 till led- 35 ningen 12, nar fluidtrycket i lelningen 11 gar Over ett forutbestdmt varde. The lines 11, 12 are connected by a safety valve 22, which flows through the fluid from the line 11 to the line 12, when the fluid pressure in the line 11 exceeds a predetermined value.
