Abstract

Rotator (1), avsett att exempelvis hängas upp med en första fästanordning (24) i en kran eller liknande för att vrida minst ett objekt som ansluts med minst en andra fästanordning (26) till rotatom (1). Rotatom (1) innefattande minst en stator (4) i vilken en rotor (3) är roterbart anordnad. Rotom (3) drivs med en i rotatom (1) integrerad hydrauliskt driven radialkolvmotor som innefattar ett flertal cylinder/kolv enheter (9). Statom (4) innefattar en övre statordel (5) och en undre statordel (6) samt en mellanliggande kamring (7). Rotom (3) är lagrat anordnad i förhållande till den övre stordelen (5) via minst ett första lager (15) och är lagrat anordnat i förhållande till den undre statordelen (6) via minst en andra lager (16). samt att tillförseln av tryckvätska till cylinder/kolvenhetema (9) sker via minst en fördelare (19). Uppfinningen kännetecknas av att fördelaren (19) är belägen under cylinder/kolvenhetema (9) medförande att lagret (16) helt eller delvist från den vertikala nedåtriktad kraft som skapas av massan i ansluten utrustning och det lyfta objekt när rotom bringas att rotera, av en motkraft som skapas av den tillförda tryckvätskans tryck mot arean vid cylinder/kolv enheterna från fördelaren (19). Vidare innefattar rotom (3) genomgående kanaler för överföring av tryckmedia vilka övergår från rotom (3) till den andra fästanordning (26) i rotoms radiella riktning.Rotator (1), intended for example to be suspended with a first fastening device (24) in a crane or the like in order to rotate at least one object which is connected with at least one second fastening device (26) to the rotator (1). The rotator (1) comprising at least one stator (4) in which a rotor (3) is rotatably arranged. The rotator (3) is driven by a hydraulically driven radial piston motor integrated in the rotator (1) which comprises a plurality of cylinder/piston units (9). The stator (4) comprises an upper stator part (5) and a lower stator part (6) and an intermediate cam ring (7). The rotator (3) is mounted in relation to the upper large part (5) via at least one first bearing (15) and is mounted in relation to the lower stator part (6) via at least one second bearing (16). and that the supply of pressure fluid to the cylinder/piston units (9) takes place via at least one distributor (19). The invention is characterized in that the distributor (19) is located below the cylinder/piston units (9) resulting in the bearing (16) being completely or partially relieved from the vertical downward force created by the mass of the connected equipment and the lifted object when the rotor is caused to rotate, by a counterforce created by the pressure of the supplied pressure fluid against the area at the cylinder/piston units from the distributor (19). Furthermore, the rotor (3) comprises through channels for the transfer of pressure media which pass from the rotor (3) to the second fastening device (26) in the radial direction of the rotor.
