Design methodology for the selection of basic components of linear machine tool axes
Král, Stanislav ; Dosedla, Michal (referee) ; Holub, Michal (advisor)
The aim of the thesis is based on specified parameters positioning units, which include stroke (1m, 2m, 4m), load (5kg, 50kg, 500kg), you place the position accuracy (0.04 mm) and dynamic (maximum attainable speed 1.5 m / s), proposals to build a ball screw, linear motor, a toothed belt and toothed comb. For selected variants of positioning units to design a 3D model of positioning units. The proposed variations to compare and define their advantages / disadvantages, techno-economic comparison, the limit values of individual designs, etc. The work includes a search drive in positioning units, design units with toothed belt, a toothed comb, ball screw linear actuator, a calculated message of individual proposals then 3D design options for the ball screw and linear motor including drawings and assembly drawings.

Animation of 2D gear meshing
Fiala, Vlastimil ; Klapka, Milan (referee) ; Hartl, Martin (advisor)
The bachelor thesis deals with the animation of planar involute gearing. The thesis gives a theoretical basis for understanding the problems of gears. Introduction of the work is focused on the description of the geometry and mesh of uncorrected planar gears focusing on the line of action. Gradually meshing of gear pairs with external, internal and rack gearing is described. Following part describes mesh of planar wheel with manufacturing rack, thus creating teeth flanks by rolling. The next section describes the problems of interference with the root curve and its impact on the gear's teeth number. The last part deals with correction of teeth by shifting profile and its effect on meshing ratios.

Design of bench type drilling machine
Malásek, Petr ; Marek, Tomáš (referee) ; Blecha, Petr (advisor)
The subject of this thesis is description of bench drill, research about companies producing bench drills and analysis of their products. Based on research, parameters of drill are chosen, 3D model is designed and basic calculations are calculated. The output of this thesis is 3D model of bench drill and drawing of assembly.
