Design of threading head with automatic reversing
Žebrák, Matěj ; Pavlík, Jan (referee) ; Tůma, Jiří (advisor)
This bachelor’s thesis deals with the design of reversing tapping head. The thesis is divided into two parts. First part is devoted to an overview of technologies for the thread producing focusing to tapping and research in field of tapping heads. Second part contains design of reversing tapping head including the necessary calculations.

Modern Tractor Transmissions
Bartošová, Daniela ; Řehák, Kamil (referee) ; Prokop, Aleš (advisor)
This Bachelor thesis concerns an overview of the modern trends in the area of tractors transmissions. It explains the reason why both the power shifts and the continuously variable transmissions. Further on, this thesis emphasizes the innovative elements of transmission concept at selected tractor manufacturers.

Control Systems of Gears Changing on Load in Tractors Gearboxes
Holub, Přemysl ; Svída, David (referee) ; Dundálek, Radim (advisor)
This bachelor thesis is interested in the overview of tractor’s gearboxes, which are changing on load. There are reasons, why it has to be costructed and there are requirements for it. There are also described PowerShifts, which allow us gear changing on load. After basic description of concrete gearbox, there is always some example of using in current tractors. In period named Mechanical gearboxes, wchich are changing partly on load there is more space for Zetor tractors and its gearboxes. In one of the last period there is important part about continuously variable transmissions where the driving speed is regulated steplessly. These gearboxes are considered to be modern technology of transfer engine torque.

Design of a boring head for a drill
Hradský, Martin ; Tůma, Jiří (referee) ; Kočiš, Petr (advisor)
The bachelor thesis, which belongs to the field of machine tool tools, deals with drilling. The thesis is divided into a search section where a review of the drill head is processed and the practical part in which the design of the drill head is made. This is particularly the head with an eccentric spindle, the movement of which on the circle will be a milling cutter that will cut the hole. The result of the design is a drill head, which consists of a two-stage planetary gear, a toothing and a toothed belt drive.
