  1. 1. On the friction and failure mechanisms of bearing and gear surfaces lubricated by a novel nanoadditive in highly stressed operating conditions

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Diego Manuel Chamorro Ruz; [2022]
    Nyckelord :micropitting; nanoadditive; gear; bearing; tribology; rolling contact fatigue;

    Sammanfattning : Obtaining an enhanced lifespan for mechanical transmissions has become a challenge in diverse application sectors. Micropitting as a contact fatigue mechanism has seriously jeopardized the well-being of rolling-sliding elements present for instance in gearboxes. LÄS MER

  4. 3. SUSTAINABLE LUBRICATION FOR FUTURE TRANSMISSIONS : Micropitting performance of Glycerol-based lubricants

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Zapata Tamayo Juan Guillermo; [2021]
    Nyckelord :micropitting; mild sliding wear; surface coating; diamond-like carbon DLC; glycerol-based lubrication; green lubricant; rolling contact fatigue; rolling-sliding;

    Sammanfattning : Achieving sustainable lubrication by using environmentally friendly formulated lubricants has became an essential component of the transition process from fossil-powered vehicles to electrified transportation. Mixtures, or aqueous solutions of molecules such as polyhydroxy alcohols, and glycols usually known as green lubricants make it possible to achieve low friction coefficients under different lubrication conditions, which constitutes a potential alternative to improve the tribological performance of moving parts in automotive systems, at the same time that the environmental requirements are satisfied.

  5. 4. Modellering och analys av kuggrigg

    Kandidat-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Martin Öun; Peter Ericson; Svante Larsson; [2012]
    Nyckelord :;

    Sammanfattning : Denna rapport har skrivits som ett resultat av ett kandidatexamensarbete på uppdrag av Sveriges Transmissionskluster i samarbete med Institutionen för Maskinkonstruktion vid KTH. Rapporten beskriver modellering samt styvhets- och egensvängningsanalyser av en kuggrigg, FZG Standard Test Rig, som vid KTH skall användas vid tester av skvalpförluster i växellådor. LÄS MER
