Design of a headstock for a machine tool
Sehon, Tomáš ; Marek, Jiří (referee) ; Hermanský, Dominik (advisor)
This master’s thesis deals with design of a headstock for a machine tool. Theoretic part of this thesis provides basic description of a horizontal machine tool. Further it is dedicated to description of a headstock of machines with extensionable work spindle. In a design part firstly optimal variant is chosen by using multicriterial analysis. Necessary calculations were done and chosen variant was developed. Design is realised by 3D CAD model and drawing documentantion.

Linear feed systems in construction of machine tools
Kolaja, Radim ; Opl, Miroslav (referee) ; Blecha, Petr (advisor)
This bachelor thesis deals with the detailed description and division of constructional componets composition of linear feed systems, which are essential part in the construction of machine tools in the manufacturing process. It describes individual subsystems, which are described in details and compared in terms of favorable and unfavorable characteristics for certain working conditions. Out of these possible ways of implementation of linear feed system is initiation one example with an overview of the basic calculations used to design project.

Ensure the stability of long ball screws and nuts
Dulava, Štěpán ; Huzlík, Rostislav (referee) ; Marek, Jiří (advisor)
This Master‘s thesis deals with the construction design of the ball screw shaft supports. Designed supports will serve to increase stability of rotating ball screws. In the introduction detailed description of the ball screws is presented including description of the individual parameters of the ball screw. Next part includes parameters of different ball screw properties and design of individual supports with description and design calculations of individual parts of the supports. Concepts of the supports will be designed in compliance with the ball screw product series of the KSK Precise Motion a.s. company.

Design and analysis of the cross table
Zemčík, Matěj ; Pavlík, Jan (referee) ; Tůma, Jiří (advisor)
This thesis deals with the design of the cross table. That is, designing a linear guide, a ball screw and a motor. In addition, dynamic simulations are used in the MSC Adams for machining cycle and the positioning cycle of the semi-product at rapid traverse. As a simulation output are the „real“ load patterns of the bearings in the placing of the ball screws and the durability of these bearings.

AC electric linear drive for paralell kinematics structures of robots
Nejedlý, Petr ; Pavlík, Jan (referee) ; Knoflíček, Radek (advisor)
Design of linear actuator for parallel kinematic structure is described in this master´s thesis. The parallel kinematic structure is described in the first part. Open kinematics structure and close kinematics structure are compared. Their benefits and disadvantages are also mentioned. Construction of some parallel robots is illustrated. Linear actuators of different company are described. Mechanical parameters and construction of linear actuator are compared. Design of linear actuator is described in practical part of master´s thesis. A few variation of linear actuator are introduced. Individual variants are evaluated by Multicriteria Decisional Analysis and a final conception is selected. Final conception of linear actuator is elaborated. Reasons for selection of every part of linear actuator are given and basic mechanical calculation design part is made. FEA analysis of the structural part of linear actuator is made. Design of linear actuator is evaluated in the final part.
