The effect of surface grooves on point contacts lubrication
Matoušek, Kamil ; Čermák, Jan (referee) ; Šperka, Petr (advisor)
This diploma thesis deals with experimental study of the effect of surface grooves on distribution of lubricant film in elastohydrodynamic lubricated point contact. Lubricant film thickness was measured by ball-on-disc apparatus using an optical interferometry technique - thin film colorimetric interferometry. The effects of groove geometry, lubricant and operating conditions were studied in this diploma thesis. The effects of these variables are evaluated based on newly suggested parameter Rgi (groove influence ratio). Groove influence ratio is defined as an influenced film thickness influenced by groove divided by film thickness for smooth surfaces.

Influence of the surface roughness features on the next rolling bearing element
Saksa, Vladimír ; Zapletal, Tomáš (referee) ; Košťál, David (advisor)
This bachelor thesis deals with investigation of influence of the surface roughness features on the next rolling bearing elements. It researches changes in the film profile entering into the contact. This thesis describes also elastohydrodynamic lubrication regime by witch each rolling bearing works as well as the difference between fully flooded and starvation contact of rolling ring with rolling bearing element. The part of the thesis is the experiment using different kinds of lubricats from which is visible really influence of these contacts. This experiment is realized on the contact simulator and the film thickness is measured using method of optical interferometry.
