Design of elongated right angle milling head for horizontal boring machine
Svoboda, Ondřej ; Tůma, Jiří (referee) ; Holub, Michal (advisor)
This thesis deals with design of right-angled elongated milling head for horizontal boring machine of FERMAT production. The thesis includes a detailed research of milling heads, a description of the head´s basic components and certain commercially available head´s comparison. Design part is describe components description and the design. Calculations are focused on determinating of forces generated during machining, setting of loading spectrum and the power load calculating individual gears during machining. In the next part is calculation of the reactions in the spindle bearings included, the equivalent load and durability of spindle bearings, spindle deformation and spindle bearings optimum distance. The thesis also includes spindle strength calculation, horizontal and vertical shafts analysis, gears design with helical teeth and gear strength. The thesis describes the design of extended milling head and particular design nodes which is supplemented by the 3D model. In this thesis is also included a drawing of assembly and components.

Construction of equipment for deburring gears
Bosák, Daniel ; Tůma, Jiří (referee) ; Holub, Michal (advisor)
This thesis deals with the design of the equipment for deburring gears on the Gleason GP 200 machine. The first part contains research of current methods of deburring. At the following analysis of the task dimensions and layout of the machine, focusing on equipment placement, are analyzed. Next, a choice of tool is made. Two variants of design solutions are outlined. One of them is more elaborated. Important structural units are solved. At the end of the thesis an analysis of the geometry and stiffness is made. The maximum equipment load is recommended with regard to the maximum deformation.

Production of gears by hobbing
Ivánek, Radim ; Kalivoda, Milan (referee) ; Jaroš, Aleš (advisor)
The aim of this study is to compare the manufacturing costs and times of a gear hobbing process. The theoretical part of the thesis is aimed to describe the gears hobbing manufacturing process, their characteristics and this way used processing materials. The practical part of the thesis is comparing the manufacturing gear hobbing costs and machining times using high-speed steel tools to sintered carbides tools in line manufacturing. This study evaluates and rationalizes all the found and calculated data.
