SKF Trafikljuskoncept - driftstemperaturområde Förbjudet driftsområde - använd ej Otillförlitlig prestanda (använd endast för korta perioder) Tillförlitlig prestanda, dvs med förutsägbar fettlivslängd TEMPERATUR (mätt på lagrets ytterring) LTL LTPL HTPL HTL LTL = Lågtemperaturgräns Den lägsta temperatur vid vilken fettet tillåter start av lagret utan svårighet LTPL = Lågtemperaturprestandagräns Under denna gräns kan tillförseln av smörjmedel till kontaktytorna bli otillräckliga. Värden är olika för rull- och kullager. HTPL = Högtemperaturprestandagräns Över denna gräns oxiderar fettet på ett okontrollerbart sätt, så att fettlivslängden inte kan bedömas tillförlitligt. HTL = Högtemperaturgräns När temperaturen överstiger denna gräns förlorar fettet sin struktur permanent (till exempel droppunkten för tvåbaserade fetter) 2010-09-08 SKF Slide 36
