Abstract

Prehajanje avtomobilske industrije proti zeleni mobilnosti prinaša nove izzive v strojništvu. Optimizacija elektromotorja, kot glavne komponente pogonskega sistema, z leta v leto vodi v boljše izkoristke, ter bolj izpopolnjene produkte. V nalogi smo se osredotočili na konstrukcijo ležajnega mesta fiksnega ležaja. Po odpovedi omenjenega detajla med preizkušanjem smo najprej natančno preučili zahteve za montažo ležaja ter obravnavali vse zunanje dejavnike med obratovanjem. V nadaljevanju smo konstrukcijski detajl pogledali tudi pri konkurenčnih proizvajalcih ter z zbranim znanjem tvorili koncepte. S pomočjo analitičnih preračunov in numeričnih simulacij smo določili optimalno konstrukcijo, katero predstavlja rešitev s pritisno ploščico. Ta je bila v nadaljevanju preizkušena na stresalniku. V raziskavi so bili odkriti glavni dejavniki, ki vplivajo na porušitev konstrukcije, hkrati pa smo razvili rešitev, ki je lahko širše uporabljena v izdelavi pogonski avtomobilskih elektromotorjev.

Secondary title: Development of a fixed bearing seat in an automotive traction drive electric motor
Secondary abstract: The transition of the automotive industry towards green mobility brings new challenges in mechanical engineering. In recent years, the electric motor, as the main component of the drive system, has been able to generate more and more energy, leading to demanding life cycles and loads. In the master thesis, we have focused on the design of the bearing seat of the fixed bearing. After the failure of the mentioned detail during testing, we first carefully examined the requirements for mounting the bearing and considered all external factors during operation. In the next steps, we have looked at the construction details of the competing manufactures and created concepts with collected knowledge. With the help of analytical preliminary calculations and numerical simulations, an optimal design that represents a solution with a fixating plate was determined. Optimal design was subsequently also tested on a shaker. In the research, the main factors influencing the collapse of structures were discovered, and at the same time, a solution that can be used more widely in the production of drive car electric motors was proposed.
