Improvements in the field of ball bearings

V diplomskem delu sem pregledal izboljšave na področju krogličnih ležajev. V zadnjih nekaj letih se je na področju standardnih krogličnih ležajev izboljšala kvaliteta obdelave tekalnih površin in kotalnih elementov, izboljšala so se tesnila in kletke v ležajih. Vse to ima za posledico, da imajo ležaji nove generacije manjše trenje, se med obratovanjem manj segrevajo in zaradi tega porabijo manj energije, so tišji in imajo daljšo življenjsko dobo. Ker so ležaji ohranili enake priključne mere kot prejšnja generacija, lahko konstruktorji z uporabo nove generacije ležajev izboljšajo lastnosti svojih naprav brez konstrukcijskih sprememb.The topic of my diploma work is improvements in ball bearings. In the past few years the quality of the raceways and rolling elements in the field of standard ball bearings, the seals and cages in the bearings has improved. The consequence of all of this is, that the new generation of bearings has reduced friction during operation and produces less heat, therefore they consume less power, are quieter and have a longer life expectancy. Because the new generation of bearings has maintained the same connecting dimensions as the previous generation, constructors can use them in order to improve the properties of their devices without design changes
