Modular linear axis
Chlapečka, Tomáš ; Bilík, Martin (referee) ; Pavlík, Jan (advisor)
This thesis contains a structural design of linear axis with a stroke up to 800mm and a maximum load of 800N. The thesis also deals with a modular assembly system of the linear axis based on the structural design. Linear axes can be fitted with rolled, whirled and grinded ball screws with thread pitch 5, 10, 16mm and rolled trapezoidal screws on pitch 4 and 8mm. The stroke of the linear axes can be selected in the range from 200 up to 800 mm, with a maximum load of 800N in all linear dimensions. The feed of linear axis is provided by shaped rolling guide way and four trucks. The modular system offers two servo motors with direct and indirect measuring four stepper engines with indirect measuring. The thesis also includes strength and functional calculations of principal components, graphs of the possible load on linear axis in different positions , durability of the ball screws, maximum speed and feed rate of the chosen screws, data sheet, 3D model, drawings and assembly drawings of the nodes.

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.

Design of linear axis for heavy machine tool
Göbel, Lukáš ; Marek, Jiří (referee) ; Hermanský, Dominik (advisor)
The content of this thesis is the description the various component of the linear feed axis, which are used in heavy duty machine tools. This describes their features, advantages and disadvantages and on these basics, are selected different appropriate design variants. In the second part of this thesis has been drawn up constructional design of these variants. They were subsequently compared and then was chosen the most ideal one for the designed machine, which is heavy machine tool upper gantry type. The work also includes the 3D CAD model of the final version and drawing documentation.
