Description

536 794 båge under denna och när slangarna är kopplade med vinkelkopplingar på rotatorns ovansida. Uppfinningen definieras av patentkraven. 536 794 arc below this and when the hoses are connected with angle couplings on the top of the rotator. The invention is defined by the claims.

Beskrivning av visat och föredraget exempel på uppfinningen Figurerna visar änden på en kranarm 11 som bär en rotator 12 via en kardanupphängning 13. Endast rotatorns överdel visas och dess nederdel är anpassad på konventionellt sätt att bära ett arbetsverktyg. Kranarmens ände har två öron 14,15 i vilka kardanupphängningens hus 16 är lagrat med två lager 17,18 sammanbundna av en axel 19. Rotatorn är lagrad i två lager 20,21 sammanbundna av en axel 22. Kranarmen har fyra anslutningar 23-26 för slangar 31-34 som är kopplade till rotatorns fyra hydraulanslutningar med vinkelkopplingar 27-29, två på var sida om axeln 22, men endast tre är synliga på figurerna.Description of the shown and preferred example of the invention The figures show the end of a crane arm 11 which carries a rotator 12 via a gimbal suspension 13. Only the upper part of the rotator is shown and its lower part is adapted in a conventional manner to carry a work tool. The end of the crane arm has two ears 14,15 in which the gimbal suspension housing 16 is mounted with two bearings 17,18 connected by a shaft 19. The rotator is mounted in two bearings 20,21 connected by a shaft 22. The crane arm has four connections 23-26 for hoses 31-34 which are connected to the rotator's four hydraulic connections with angle couplings 27-29, two on each side of the shaft 22, but only three are visible on the fi gures.

Slangarna 31,32 till höger i figurerna sträcker sig ner runt axeln 22 och är kopplade med vinkelkopplingarna 27,28 till vänster om axeln 22 i figurerna. På motsvarande sätt sträcker sig slangarna 33,34 ned till vänster om axeln 22 och sträcker sig i en båge under axeln 22 och är kopplade med vinkelkopplingar till höger om axeln 22. Genom att hälften av rotatorns anslutningar är placerade på ena sidan om axeln 22 och de andra på andra sidan får anslutningarna plats i skydd och genom att de sträcker sig i en böj under axeln kan de ta upp rörelserna under svängningen kring axlarna 19,22.The hoses 31,32 to the right of the fi gures extend down around the shaft 22 and are connected to the angular couplings 27,28 to the left of the shaft 22 in the figures. Correspondingly, the hoses 33,34 extend down to the left of the shaft 22 and extend in an arc below the shaft 22 and are connected by angular couplings to the right of the shaft 22. In that half of the rotator connections are located on one side of the shaft 22 and the others on the other side have the connections in place in protection and by extending in a bend under the shaft they can absorb the movements during the pivot about the shafts 19,22.
