Condition monitoring of small ball bearings
Šváb, Štěpán ; Pikula, Stanislav (referee) ; Havránek, Zdeněk (advisor)
The aim of this thesis was to build equipment for testing bearing condition analysis during its life. The theory of bearing parameter and diagnostics methodology for their analysis are discussed. Hardware used for device design and data collection. Finally, the course of measurement and software evaluating the end of the test are discussed.

Desingn of independent drives for five-spindle automatic lathe
Pavelka, Radomil ; Pavlík, Jan (referee) ; Blecha, Petr (advisor)
The subject of the thesis is design of independent spindle drive for multi-spindle automatic lathe MORI-SAY TMZ 520 CNC manufactured by TAJMAC-ZPS. The thesis will introduce the representatives of manufacturing program of TAJMAC-ZPS multi-spindle automatic lathes division and there will be a brief description of their main constructional parts. The main objective of the thesis is an engineering design of testing device which will be bulit for verification of the correct drive concept. There is also many calculations and detailed description of the engineering design. The testing device is made for internal needs of TAJMAC-ZPS.

Design of spindles for multi-spindle automatic lathe
Kráčmar, Tomáš ; Holub, Michal (referee) ; Vetiška, Jan (advisor)
This master‘s thesis contains a design of multi-spindle automatic lathe spindles for the work of the rods maximum diameter of 7 mm. The work deals with a new concept of the drive spindle, where the spindles are driven by external asynchronous motor through the gears with internal teeth attached to the outside of the spindle drum instead of the current method of driven by central coaxial shaft. The thesis research of multi-spindle lathes including a description of the main nodes, design, strength calculations, bearing durability and a simulation model for simulation acceleration and load drives and spindles from the cutting process.
