Crank mechanism of a gas V-sixteen engine
Čep, David ; Novotný, Pavel (referee) ; Píštěk, Václav (advisor)
Diploma thesis is trying to analyze crank mechanism of a gas V-sixteen engine. Kinematics and balance crank mechanism are analyzed, dynamic model parameters are dermined, natural frequency of the torsional system are calculated, coupling parameters are designed and torsional problem with attached electric generator is analyzed.

Balancing Shafts Support Optimalization for Zetor 4V UŘ III Engine
Zemčík, Tomáš ; Franz, Rudolf (referee) ; Rauscher, Jaroslav (advisor)
To make a check of an contemporary balancing verification of diesel engine Zetor UŘ III with type identification 1505, the engine power 90 kW and especially friction bearing design, which could replace existing needle bearing HK 4520 type, is the aim of this diploma thesis. Bearing type modification requires constructional adjustment of engine block and balancing shaft and therefore this proposal for construction another aim in my diploma thesis. The last part of my diploma thesis is an economic balance original imposition against newly designed. Calculations are made using mathematical software MathCad, the balancing shaft is made using ProEngineer software and control calculations of bearing stresses are made with ADAMS and FEM of ANSYS system. Motivation to write this work is to prove the possibility how to decrease manufacturing costs of ZETOR TRACTORS a.s. company.

Small rotor dynamic balancer
Staněk, Michal ; Vyskočil, Pavel (referee) ; Kubíček, Michal (advisor)
Balancing of rotors is used to remove unwanted vibrations caused by uneven distribution of mass around the axis of rotation of the rotor. Operation of an unbalanced rotor may causes shortening of bearing life, fatigue of materials and deformation of shafts. This work deals with construction of a balancing machine (balancer). Because of its good properties, a soft bearing type balancer was chosen for construction. This type of balancer achieves higher sensitivity at the cost of calibration required for each type of rotor. To capture the magnitude of vibration electrodynamics sensors were chosen. To enter data and display results a microprocessor is used.

Balancing Rotors of Steam Turbines
Filip, Patrik ; Šnajdárek, Ladislav (referee) ; Kracík, Petr (advisor)
This bachelor’s thesis is a technical research dealing with issues of balancing turbine rotors and generally describing international standarts commonly used for balancing rotors. The first part is about unbalance in general context. The next part classifies types of rotors, standarts for balancing rotors and balancing methods. Then there is a description of a balancing device. The last part of this thesis includes a step by step process of balancing a specific rotor.

Turbocharger Rotor Balancing
Šárovec, Marek ; Zubík, Martin (referee) ; Knotek, Jiří (advisor)
This bachelor’s thesis is specialized search dealing with issues of turbocharger rotor balancing. This work is divided into three main parts. First part deals with history of turbocharger and basics of turbocharger construction. Second part talks about types of unbalance and how to balance. Also, there is description of balancing machines. Last part depends on previous part because there is application of balancing on automotive turbocharger.

Balancing turbines rotor
Peterka, Zdeněk ; Kracík, Petr (referee) ; Fiedler, Jan (advisor)
This bachelor’s thesis is specialized search dealing with issues of balancing turbines rotors. The first part of this work is devoted to general problems of balancing turbines rotors and basics of balancing turbines rotors. In the second part of this thesis there is a documentation of balancing device so-called „shelter“. The third part already discussed about the very processes of balancing turbines rotors. In the last part there two examples of practical balancing turbines rotors.
