Realization of educational problems based on experimental apparatuses with oil and air lubricated bearings
Kučera, Ondřej ; Veselý, Oldřich (referee) ; Vaverka, Michal (advisor)
This master thesis is focused to make education exercise on simulation equipment, tilting pad apparatus and air bearing apparatus. Exercise are, for better understanding problems, completed about exercise measurement viscosity. Were to be proposed three separate exercise for exercising, which were to be well – tried. Measured data from stations for sliding bearing will students confront with computed data. To every exercise are created instructions for exercising, educational presentation and poster to arrangement.
Slide bearing parameters of modern combustion engines
Dvořák, Martin ; Píštěk, Václav (referee) ; Novotný, Pavel (advisor)
The objective of this bachelor‘s thesis is to provide general information on sliding bearings and their advantages and disadvantages. The thesis is divided into five parts that deal with individual topics and issues. The first one is concerned with the bearings themselves, their partition and development. The second part compares sliding bearings and rolling contact bearings and their pros and cons. The next part then describes their main parameters, e.g. the friction loss or various lubrication methods. The fourth one summarizes several examples of practice, like lubricating in extreme working conditions and an overview of bearing failures. The last part deals with the construction of sliding bearings used in combustion engines, materials used to produce sliding bearings and with the issue of lubrication, which is essential for this type of bearings.
Modern Turbocharger Rotor Supports
Kortán, Daniel ; Raffai, Peter (referee) ; Knotek, Jiří (advisor)
This bachelor thesis focuses on the options of impositions of turbocharger rotors. The first part focuses on the construction of turbochargers and description of the principle of turbocharging engines with internal combustion. The second part focuses on the description of the construction of rolling and sliding bearings and explanation of options the particular types of impositions used in turbochargers nowadays.
Research of Coatings of Hydrodynamically Lubricated Sliding Bearings for Combustion Engines
Repka, Martin ; Čermák, Roman (referee) ; Petrůj, Jaroslav (referee) ; Havlica, Jaromír (advisor)
Hlavní náplní této dizertační práce je výzkum a vývoj nové povrchové vrstvy pro kluzná ložiska na bázi pevných lubrikantů v polyamid-imidové polymerní matrici se zlepšenými tribologckými vlastnostmi. Podklady pro materiálovou kompozici vzešly z expertízy komerčně dostupného povlaku, respektive jeho povrchovou analýzou v mezných operačních podmínkách. Charakterizace mazného oleje před a po tribotestování společně s detailní povrchovou analýzou dala podmínky pro vznik materiálové formulace. Další část práce se zabývá studiem přípravy a vývojem aplikačního nanášení s přípravou polymerní směsi. Nakonec je popsána studie vlivu sulfidu molybdeničitého a grafitu, jakožto pevných lubrikantů pro zlepšení třecích vlastností a hydroxidu vápenatého pro potenciální zpepšení otěruvzdornosti výsledného povrchu pro palikaci kluzných ložisek.
