Description
455 581 Uppfinningens uppgift består i att utesluta att spelet mellan trummans underdel och den radiellt invändigt liggande ringmuttern för förbindning av trumlocket ökar i driftstillståndet för en cent- rifugalseparator och excentriskt förskjuter ringmuttern. The object of the invention is to exclude that the play between the lower part of the drum and the radially inner ring nut for connecting the drum cover increases in the operating state of a centrifugal separator and eccentrically displaces the ring nut.
Enligt uppfinningen löses detta genom att ringmuttern på sin inre periferi uppvisar flera slitsar. Dessa slitsar är företrädesvis an- ordnade i en vinkel relativt ringmutterns axel.According to the invention, this is solved by the ring nut having several slots on its inner periphery. These slots are preferably arranged at an angle relative to the axis of the ring nut.
Genom belastningarna på trummans underdel genom den egna centrifu- galkraften och det inre vätsketrycket erhålles större formförändrin- gar hos centreringspassningen och i gängområdet för trummans under- del än i ringmuttern, som belastas i radiell riktning enbart av den egna centrifugalkraften. För utjämning av de olika formförändring- arna hos de båda delarna är ringmuttern enligt uppfinningen så ut- formad att ett flertal slitsar av liten bredd är anordnade i ring- muttern, vilken företrädesvis är anordnad i en vinkel mot axeln.Due to the loads on the lower part of the drum by its own centrifugal force and the internal liquid pressure, greater deformations are obtained in the centering fit and in the threaded area of the lower part of the drum than in the ring nut, which is loaded in the radial direction only by its own centrifugal force. To compensate for the different shape changes of the two parts, the ring nut according to the invention is designed such that a plurality of slots of small width are arranged in the ring nut, which is preferably arranged at an angle to the shaft.
Genom dessa slitsar i ringmuttern erhålles en uppdelning av det in- re periferiområdet i segment. Dessa erhållna segment på den inre periferin av ringmuttern verkar som belastningsmassor för det oför- svagade tvärsnittet och är till sina massor så valda att formför- ändringarna hos ringmuttern i centrifugalseparatorns driftstillstând blir lika stora som de hos trummans underdel, så att ingen spel- förstoring uppkommer mellan trummans underdel och ringmuttern.Through these slots in the ring nut, a division of the inner peripheral area into segments is obtained. These obtained segments on the inner periphery of the ring nut act as load masses for the weakened cross-section and are in their masses so selected that the deformations of the ring nut in the operating condition of the centrifugal separator become as large as those of the lower part of the drum, so that no play magnification occurs. between the bottom of the drum and the ring nut.
Uppfinningen beskrives närmare nedan under hänvisning till bifoga- de ritningar, där fig. 1 visar en tvärsektion av en del av en trum- ma till en oentrifugalseparator, medan fig. 2 visar ett delsnitt genom ringmuttern.The invention is described in more detail below with reference to the accompanying drawings, in which Fig. 1 shows a cross section of a part of a drum of an centrifugal separator, while Fig. 2 shows a partial section through the ring nut.
I fig. 1 visas trummans underdel 1, trummans lock 2 och den delar- na 1 och 2 förbindande ringmuttern 3.Fig. 1 shows the lower part 1 of the drum, the lid 2 of the drum and the ring nut 3 connecting the parts 1 and 2.
I fig. 2 visas ringmuttern 3 som en separat del med slitsar 4, som företrädesvis bildar en vinkel mot ringmutterns 3 axel. Ringmut- tern 3 framställes med minimalt spel mot den gängade delen av trum- mans underdel 1 för att tillförsäkra manuell monter- och demonter- barhet. På dess inre periferi finns ett flertal slitsar 4. De i ringmuttern 3 anordnade slitsarna 4, vilka företrädesvis är rikta- 455 381 de i en vinkel mot axeln, uppdelar det inre periferiomrâdet av ringmittern 3 i segment, vilka i driftstillståndet verkar som be- lastningsmassor för det oförsvagade tvärsnittet. Antalet och for- men av slitsarna 4 är så valda att i trummans driftstillstând blir formförändringen hos ringmuttern 3 lika stor som formförändringen hos den ringen omgivande gängdelen av trummans underdel. Om en be- lastning på trummans underdel 1 uppkommer i driftstillstândet ge- nom egen centrifugalkraft och vätsketryck och därmed en formför- ändring, så anpassas formförändringen hos ringmuttern 3, som en- bart belastas genom egen centrifugalkraft, till formförändringen av trummans underdel 1 genom uppdelningen av det inre periferiområ- det av ringmuttern 3 i segment, varigenom ingen förstoring uppkom- mer av det minimala spelet i driftstillståndet. Anordnandet av slit- sarna i en vinkel mot ringmutterns 3 axel leder till god aerody- namik. Genom orienteringen av slitsarna mot rotationsaxeln och ro- tationsriktningen uppnås ett minskat luftbuller, varigenom separa- torns bullernivå reduceras.Fig. 2 shows the ring nut 3 as a separate part with slots 4, which preferably form an angle to the axis of the ring nut 3. The ring nut 3 is manufactured with minimal play against the threaded part of the drum part 1 to ensure manual assembly and disassembly. On its inner periphery there are a plurality of slots 4. The slots 4 arranged in the ring nut 3, which are preferably directed at an angle to the axis, divide the inner peripheral area of the ring nut 3 into segments which in the operating state act as load masses. for the weakened cross section. The number and shape of the slots 4 are chosen so that in the operating condition of the drum the deformation of the ring nut 3 becomes as great as the deformation of the threaded part of the lower part of the drum surrounding the ring. If a load on the lower part 1 of the drum arises in the operating condition by means of its own centrifugal force and liquid pressure and thus a change in shape, the change in shape of the ring nut 3, which is only loaded by its own centrifugal force, is adapted to the change in the lower part 1 by the partition of the inner peripheral area of the ring nut 3 in segments, whereby no magnification arises from the minimal play in the operating condition. The arrangement of the slits at an angle to the axis of the ring nut 3 leads to good aerodynamics. By orienting the slots towards the axis of rotation and the direction of rotation, a reduced air noise is achieved, whereby the noise level of the separator is reduced.
Fördelen med uppfinningen är även att en förstoring av det minima- la spelet mellan gängdelen hos trummans underdel 1 och ringmuttern 3 förhindras genom denna anpassning av formförändringen hos ring- muttern 3 i driftstillstånd till formförändringen hos den gängade delen av trummans underdel 1, varför ingen förskjutning av ring- massan kan uppstå så att därmed en negativ inverkan på trumman und- vikes.The advantage of the invention is also that an enlargement of the minimum clearance between the threaded part of the drum part 1 and the ring nut 3 is prevented by this adaptation of the deformation of the ring nut 3 in operating condition to the deformation of the threaded part of the drum part 1, so no displacement of the ring mass can arise so that a negative impact on the drum is avoided.
