Description

l5 20 25 30 35 466 563 2 ständiga materialet av den intill de höga temperaturerna belägna innerringdelen av 80 MoCrV 42 l6 (M 50) eller av X 102 CrMo 17 (AISI 440 C). Dessa material undergår vid höga temperaturer ingen funktionsförsämrande nedsätt- ning av hårdheten. Därigenom bibehålles lagrets funktions- förmåga även vid högre temperaturer. Eftersom även via axeln värme når fram till innerringarna är den i krav 3 angivna åtgärden mycket ändamålsenlig. Genom spalten mellan axeln och innerringen närmast kulrummet reduceras värmeövergången, och genom avsaknaden av en spalt uppnås ändå en god sits.
För att i innerringens ändsidesområde värmeövergången skall reduceras ytterligare kan det enligt en speciell utföringsform vara ändamålsenligt att vid dess ändsidor anordna en mellanring med förhöjt värmeövergångsmotstånd.
Uppfinningen skall nu förklaras närmare i anslutning till två figurer. På dessa visar: Fig l ett tvärsnitt genom lagringen enligt uppfinningen för en avgasturboladdare och Fig 2 en variant till fig 1.
Det tvåradiga vinkelkontaktkullagret uppvisar enligt fig l en endelad ytterring l, varvid kulraderna 2 är anordnade på stort avstånd från varandra. Den breddade innerringen är delad och består av två innerringdelar 3 och 4. De sistnämnda sitter på en axel 5, varvid inner- ringen 4 sitter på den sidan där de vid avgasturboladdare rådande höga temperaturerna uppträder. Den sistnämnda innerringen består därför av material med hög värmebestän- dighet. Därigenom reduceras starkt risken för lagerhaveri.
Genom innerringens delning består den andra innerring- delen av billigt, normalt rullningslagerstål.
Värmeövergången reduceras ytterligare genom att mellan innerringdelen 4 och axeln 5 vid kulraden 2 är anordnad en spalt 6. För att trots detta uppnå en god sits på axeln 5 uppvisar innerringdelen 4 i det därintill belägna området 4' en borrningsdiameter som svarar mot axeln 5. Dessutom medför spalten 6 fördelen att passnings- av 466 565 3 toleransernas inverkan mellan axeln och innerringen reduce- ras till lagrets mittradialspel.
Mycket fördelaktigt är även anordnandet av en mellan- ring 7 med förhöjt värmeövergångsmotstånd på innerringens 4 ändsida (se fig 2). Därigenom reduceras rullningslagrets temperaturbelastning ytterligare.
