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.

Servodrive Clamping Unit
Šťastný, Libor ; Hampl,, Štěpán (referee) ; Foller, Bronislav (advisor)
Design servodrive clamping unit with pneumatic or mechanic multiplier. Unit has be instrumental to strength clamp parts in tension technical machines. Frame unit’s is complicate from massive and movable clamping board and is self-supporting. Unit has be solution like incorporated modulus. Target is proposal main driving period for movable clamping board. Work up proposal constructional solution, drawing listings, production drawing of the three engaged part of, BOM. Computational report must include calculations drives, constructional knots and their verification and further needed strength calculation and analyses. Proposal treatment tribotechnical knots. Analysis construction from standpoint safety in operation according to NV24/2003 and analysis safety hazards. Part of work must be and economic analysis resultant solution.

Service life calculations in machine tools
Novotný, Lukáš ; Marek, Tomáš (referee) ; Holub, Michal (advisor)
The aim of this Bachelor’s Thesis is comparison of service life time calculations of machinetool construction parts according to different producers. The first part of thesis describes three important parts of machine-tools as linear guides, ball screw bearings and ball screws. Main part of thesis refers about search of service life time calculations itself according to various manufacturers and their comparison.

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.
