Zasnova načina za merjenje izgub v ležajih in primerjalni test krogličnih ležajev : zaključna naloga Razvojno raziskovalnega programa I. stopnje StrojništvoGladek, MarkZaradi velikega števila izvedb ležajev postaja vse pomembneje dobro poznati lastnosti ležaja med obratovanjem, še posebej pri elektromotorju sesalne enote, kjer vrtilne hitrosti lahko presežejo ... 70.000 vrtljajev na minuto. To zaključno delo opisuje zasnovo načina za merjenje izgub v ležajih, saj je z dosedanjimi postopki težko določiti spreminjanje vrednosti izgub v različnih fazah obratovanja ležaja. Izbrana metoda je bila merjenje momenta na zunanjem obroču krogličnega ležaja z uporabo senzorja sile, in merjenje temperature z uporabo IR senzorja. Omenjena metoda prinaša več prednosti, saj ni potrebe po uporabi sklopke, ki omejuje maksimalno vrtilno hitrost in pri višjih vrtljajih manjša natančnost meritve. Z opravljenimi 5-urnimi testi smo ugotovili, da so velikosti izgub krogličnih ležajev tipa 608 v fazi utekanja od 5 do 58 W, v ustaljeni fazi pa se vrednosti znižajo na 3 do 26 W, odvisno od konfiguracije ležaja. Temperature krogličnih ležajev so bile od 45 do 80 °C, prav tako odvisno od konfiguracije ležaja.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [M.
