Description of different sorts of HARMONIC-DRIVE gear box
Brus, Jan ; Pavlík, Jan (referee) ; Pavlík, Jan (referee) ; Kolíbal, Zdeněk (advisor)
The Bachelor’s thesis contains a technical search describing different sorts of harmonic drive gear-boxes. The search is engaged in the description of characteristics and possibilities of the application of particular sorts of harmonic drive gear-boxes, including operating characteristics (graphs), analysis of individual parts and the principle of operation. Further a comparison with other types of commonly used gear-boxes (cycloidal, classical gear-boxes) is presented. In the end the advantages and disadvantages focused on the usage and characteristics are summarized.

Design of a test rig for a wear test of inner ball joints
Blecha, Martin ; Pavlík, Jan (referee) ; Knoflíček, Radek (advisor)
This diploma thesis deals with the design of several variants of test rig for tests of axial ball joints of passenger cars. The individual design variants are evaluated based on the evaluation matrix and then the best option is selected. Selected proposal includes a complete design including 3D models and strength analyses that focus on the most stressed construction nodes. These design nodes are solved using the finite element method. Hydraulics and hydraulic elements are equipped by the existing equipment from a test lab. At the end of this thesis is solved risk analysis of the new construction and its economic evaluation.

Design of small table saws
Stuchlík, Petr ; Vetiška, Jan (referee) ; Pavlík, Jan (advisor)
The main aim of this thesis is the engineering design of a small table circular saw according to the specified parameters. At first, the types of machines available on the market are named and analyzed in detail. Afterwards, the engineering design of the machine is created. The following part is concerned with the individual parts,, tilting of the saw blade, maximum cutting pull through linkage with motion screw and checking of deformation of he critical parts of the machine. The previously specified motor guerantees the power. The fundamental parameter is the functionality of the construction and its cutting conditions. The thesis also includes drawings of selected parts.

Interchangeable three-axis tool head for CNC portal milling machines
Balek, Jan ; Pavlík, Jan (referee) ; Marek, Jiří (advisor)
This master’s thesis is focused on design of interchangeable three–axis tool head for CNC portal milling machines. The first part is devoted to a survey of the current state of technology and the representation of individual types of heads on the market. Furthermore, several possible variants of construction are proposed and the most optimal one is selected using multicriteria analysis. It is created a 3D model of selected variant, drawing documentation and technical calculations.

Design of working arm for threading machine
Řezníček, Marek ; Tůma, Jiří (referee) ; Pavlík, Jan (advisor)
The aim of this work is to propose the construction of working arm threading / drilling. Working arm provides "its" vertical position of the tool axis in the working range and reduces the force effect of cutting forces and weight. The work includes 3D models and drawings, including the calculation of the components.
