Design of the device for research on lubrication of gears
Žáček, Jan ; Hartl, Martin (referee) ; Svoboda, Petr (advisor)
The master´s thesis is focused on the design and implementation of the laboratory stand for studying lubrication of gears. Specifically, to assess the effect of lubricant contamination on gears. The device uses the Niemann closed circuit concept which in practice is called „back to back“. Firstly, in the theoretical part, the test circuits uses for testing gears are described and one of the standardized procedure for experimentation is presented. Based on research studies, basic parameters for the design and creation of conceptuals are determined. The practical part consists not only the design of this stend, but also including test run and the description of the procedure on that device. The result of this master´s thesis is the functional experimental device for the future development of intelligent lubrication systems.

Construction of reversible swirl turbine
Kosar, Jakub ; Štégner, Ladislav (referee) ; Haluza, Miloslav (advisor)
The thesis deals with the construction design of reversible swirl turbine used in a tidal range power plant for bidirectional operation. The theoretical part provides an overview of state-of-the-art technologies in the usage of tidal energy, mostly by means of tidal range and stream tidal power plants. It also analyses respective designs of tidal turbines and their advantages and disadvantages. The practical part of the thesis demonstrates individual steps applied when examining loading forces and also shows the design method and strength inspection procedure of the turbine and its parts, especially of the impeller, gears, shafts and bearings. Lastly, the paper outlines the selection approach of the most appropriate water plant generator.

Continual helicoidal mixer
Pelka, Tomáš ; Malach, František (referee) ; Malášek, Jiří (advisor)
This diploma project works out and is focused on the continual mixing process of the particular matters. The project is divided into following chapters. Chapter 1 includes mixing theory and information of the experimental work of the particular matters for blade using. In chapter 2 there is Evaluation and calculation of the technical parameters for the mixer. Chapter 3 deals with the engine proposal and chapter 4 includes calculation and design work of the gear transmission. Chapter 5 includes the stress analysis of the shaft and blade with the I-deas software. In attachment there are also the mixer arrangement drawing and detailed drawings of the key parts and groups for the mixer.

Modular concept of roller conveyor system
Novotný, Lukáš ; Nosterský, František (referee) ; Pokorný, Přemysl (advisor)
This diploma thesis is dealing with the modular project of a roller conveyer track for transport of europallets with the loading limit of 1200 kg and its use in practise. There are also mentioned possible construction solutions and the actual construction project. It is followed by calculating and modular project of direkt conveyer. Further on, I am dealing with the project of a sliding turntable of cable loops and surfaře covering. In the conclusion, I think out the problems of sensors and a possible operating conveyer.
