Description
^80Q1094f5 10 15 20' ZS 30 ru ett dubbellager undvikes överbelastning av lagerytorna samt förbättras lagersmörjningen. Ett dubbellager enligt uppfin- ningen kan dessutom utsättas för böjpåkänníng och erfordrar i radiell riktning ej större utrymme än ett dellager. ^ 80Q1094f5 10 15 20 ' ZS 30 ru a double layer avoids overloading of the bearing surfaces as well the bearing lubrication is improved. A double layer according to the invention can also be subjected to bending stress and requires in the radial direction no more space than a partial bearing.
Bifogad ritning visar ett utföríngsexcmpel och ett före- draget användningsexempel av ett dubbellager enligt uppfin- ningen, varvid fig. 1 visar dubbellagret med två axiellt bred- vid varandra liggande rullningslager och fig. 2 lagringen av omställbara propellerblad vid ett vindkraftverk. I lig. 1 upp- bär en vridfast del 21 medelst bultar 23 en lagerring 22.The accompanying drawing shows an embodiment and an embodiment drawn use example of a double bearing according to the invention Fig. 1 shows the double bearing with two axially wide adjacent rolling bearings and Fig. 2 the bearing of adjustable propeller blades at a wind turbine. I lig. 1 upp- a torsionally fixed part 21 carries by means of bolts 23 a bearing ring 22.
Lagerringen 22 bildar tillsammans med rullningskroppur 28 och en flytande lagrad lagerbussning 27 dubbellagrets ena del- lager. Dubbellagrets andra dellager bildas av en lagerbussning 27, rullningskroppar 29 och en lageryta hos en lagerring 25, vilken medelst bultar 26 är förbunden med ett vridrörligt element 24. De båda dellagren är alltså enligt uppfinningen anordnade axiellt bredvid varandra, varvid lagerbussningen 27, vilken omsluter lagerringarnas 22 och 25 lagerytor, uppvisar två löpytor bredvid varandra vid dess insida. Vid lagerbuss- ningens 27 övre kant är anordnad en tandkrans 30, i vilken en vid den vrídbara delen 24 anbríngad spärrhake 31 kan ingripa.The bearing ring 22 together with the rolling body clock 28 and a floating bearing bearing bushing 27 one part of the double bearing stock. The second sublayer of the double bearing is formed by a bearing bushing 27, rolling bodies 29 and a bearing surface of a bearing ring 25, which by means of bolts 26 is connected to a rotary movable element 24. The two sublayers are thus according to the invention arranged axially next to each other, the bearing bushing 27, which encloses the bearing surfaces of the bearing rings 22 and 25, has two running surfaces next to each other at its inside. At the warehouse bus The upper edge of the ring 27 is provided with a ring gear 30, in which a locking hook 31 mounted on the rotatable part 24 can engage.
Genom användning av vardera en frihjulskoppling mellan å ena sidan mellanringen och å andra sidan det vrídfasta resp. det vridbara elementet tillses att, alltefter vridriktning, är vid varje tillfälle_endast ett av dubbellagrets dellager verksamt.By using each a freewheel clutch between one on the other hand the intermediate ring and on the other hand the torsionally fixed resp. the the rotatable element ensures that, depending on the direction of rotation, it is wide each occasion_only one of the double layer sub-layers operates.
Fig. 2 visar axeln 40 hos en vindkraftpropeller vid vilken är fäst ett propellernav 41. Vid navet 41 är vridbart lagrade två propellerblad 42 och 43. Såsom lager 44 resp. 45 användes därvid på fördelaktigt sätt dubbellager enligt fig. 1 så att propellerbladen 42 och 43 kan inställas dels för att uppnå en vid rådande vindhastíghet maximal verkningsgrad, dels för att sätta igång och stoppa vindkraftverket. ' få' ; än gšrqflsflï n. n :7 IFig. 2 shows the shaft 40 of a wind power propeller at which is attached a propeller hub 41. At the hub 41 are rotatably mounted two propeller blades 42 and 43. As bearings 44 resp. 45 was used thereby advantageously double layer according to Fig. 1 so that propeller blades 42 and 43 can be adjusted partly to achieve one at the prevailing wind speed maximum efficiency, partly to start and stop the wind turbine.
