Production of planetary gear set model on 3D FDM printer
Magdon, Jan ; Prokeš, Tomáš (referee) ; Zemčík, Oskar (advisor)
This Bachelor's Thesis is looking into designing of a planetary gearbox then subsequent production with using the Fused Deposition Modeling (FDM) technology. The first part describes the production process using additive technologies, focusing mainly on FDM technology with properties of materials used in this method, then the theory of planetary gears with their practical use. The second part is devoted to production of model planetary gearbox, which is designed with regard to possibilities of FDM printer. Single parts were designed in 3D programme Autodesk Inventor Professional 2016. Finally the product is evaluated technically and economically.

Project of service lift
Drápela, Josef ; Malach, František (referee) ; Malášek, Jiří (advisor)
This diploma thesis deal with project of service lift. The service lift is drive by special mechanism using thrust chain. The chain is led from chain accumulator over sprocket gear to vertical guiding groove. Lift car is connected to the end of chain. There are designed and described the most important constructional unit of service lift in this thesis. But the most attention is pay to drive, including break system and chain accumulator. The drive is consist of electric motor, clutch, break, planetary gearbox and sprocket gear.

Press LKJP 250
Dvorník, Milan ; Dokoupil, Vladimír (referee) ; Omes, Jiří (advisor)
This Master thesis deals with the design concept of press drive of LKJP 250 press with planetary gearbox. It is a single one-point crank universal press, which is designed for cold-forming operations. The press is used for operate in single stroke mode or continuous operation when engaged in an automatic press line. The first part of the thesis deals with the research in the field of mechanical crank press drives arrangement and kinematic analysis, followed the description of the main parts of the press drive. The second part of the thesis deals with the design of the press drive. The solutions are suggested in several possible options with performing basic calculation. On the basis of the required criteria, the most suitable variant is chosen, for which detailed design and control calculations of individual design nodes of the press drive are performed. Part of this thesis also includes the required technical drawing documentation of the mechanical press.
