Animation of cylindrical gears meshing
Kvarda, Daniel ; Klapka, Milan (referee) ; Hartl, Martin (advisor)
This thesis deals with meshing relations, geometric, kinematic and force effects occuring during meshing of cylindrical gears with straight and helical teeth. This problematic is clarified with created animations, that are explained and described in this thesis. Animations serve for educational purposes.

Elastohydrodynamic lubrication of elliptical contacts
Hodás, Ladislav ; Vaverka, Michal (referee) ; Hartl, Martin (advisor)
Principal intention of this thesis is comparation of given equations for minimal and central thickness of elastohydrodynamical lubricant film at elliptical contact between smooth rubbing faces in regular isothermal conditions. Thereinafter, possible approaches to assessment of thickness of lubricant film and verification of their validity via experiment are trashed out.
