Energetic model of linear axis with ball screw and servodrive
Sládek, Vojtěch ; Tůma, Jiří (referee) ; Huzlík, Rostislav (advisor)
The aim of the thesis was to study the Energy Models of Linear Axes with Ball Screws and Servo Drives, to analyze the individual parts of the axis with respect to losses, the methodology of calculating the losses on the electrical part and the mechanical part of the drive and creating a complex algorithm that calculates the energy consumed for the specified motion. The thesis is divided into a theoretical and practical part, where the theoretical part is divided into the treatise on the electrical part of the axis and its losses and the part that deals with the mechanical part and its losses. The calculation is divided into the basic verification algorithm and the calculation on the given example. Each calculation is calculated for both linear acceleration and S-curve acceleration. For both types of acceleration, the result of energy and its course over time is also the waveforms of position, velocity, acceleration, angular acceleration, moments, powers, power, speed and currents over time.

Lathe spindle
Zábojník, Petr ; Tůma, Jiří (referee) ; Blecha, Petr (advisor)
Bachelor’s thesis will be talking about one of main parts of lathe, about spindle. In first part I’m going to make a research in this subject. I will mention about a history, development and types of lathe. Following lines will be about function of spindles and their separation in terms of drive. I’m also going to focus on the impact of toughness and precision of the spindle imposition on machining accuracy. Conclusion of the first part will be fulfill with the selection of bearings, methods of work holding, lathe manufacturers and types of lubricating. The second part will be designing of spindle itself. Complemented with an assembly drawing and 3D model.

Design of a portable machine for machining large diameter pipes
Boháč, Josef ; Pavlík, Jan (referee) ; Tůma, Jiří (advisor)
This diploma thesis deals with the design of a portable machine for machining large diameter pipes. This thesis is divided into research, calculation, design, and construction parts. The introductory part is devoted to research in the field of joining large diameter pipes, with a focus on flanged and welded joints. Based on the findings from the research part, several construction solutions were considered. In the next part, the most suitable design solution was selected using a multicriteria analysis technique and subsequently elaborated on in detail. The following chapter deals with the calculation of maximal cutting forces and the selection of motor. An air motor was chosen as the most suitable option for the proposed machine. This part is followed by the computational part, which includes strength calculations for the critical parts of the machine. The final part of the thesis is devoted to the construction itself and the description of the individual construction nodes of the machine. The thesis also includes a 3D model, drawings of selected parts, and an assembly drawing.
