Application of plain bearings for four-stroke internal combustion engines
Šedo, Matej ; Janoušek, Michal (referee) ; Drápal, Lubomír (advisor)
Subject of this thesis are plain bearings and especially their application for four-stroke internal combustion engines. Thesis is divided into two main parts. The first part provides a basic description of plain bearings, their distribution and evolution. It also discusses their materials and the theory of hydrodynamic lubrication. The second part covers concept of sliding bearings in internal combustion engines and their load associated with the election of right material. It also includes description of particular application of plain bearings and the method of oil distribution. It handles the mounting of crankshaft and camshaft, piston pin, connecting rod and other places where sleeve bearings are use.

Power Losses of a Rolling Bearing
Šedo, Matej ; Novotný, Pavel (referee) ; Drápal, Lubomír (advisor)
Subject of this thesis is analysis of friction power losses in rolling bearings and design and implementation of computing program. Thesis is divided into six chapters. At the beginning there is overview of different types of rolling bearings and their system of lubrication. Fundamentals of elastohydrodynamic lubrication are described together with effects that occur in lubricant. Remaining part is focused on friction in rolling bearing its sources and calculation. Other programs for computing friction losses are shown and own program is designed. Designed program is applied on bearings of chosen type and results are compared with existing models.
