Tracked auxiliary vehicle for driving in the snow
Semančík, Adam ; Zeizinger, Lukáš (referee) ; Kašpárek, Jaroslav (advisor)
This bachelor's thesis deals with the conceptual design of an auxiliary tracked vehicle, designed for the support of skiing in snowy terrain. The research part deals with a more detailed specification of the chassis for snowy terrain and an analysis of a similar tracked vehicle. The practical part is focused on the design of the vehicle, power and strength calculations of individual parts of the vehicle and a description of individual structural units. Part of the work is an annex with a drawing documentation of the vehicle.

Cordless drill powered hobby car
Valla, Tomáš ; Böhm, Michael (referee) ; Štětina, Josef (advisor)
This bachelor thesis deals with the design of a cordless drill powered hobby car. The cordless drill must remain usable for normal use. The theoretical part deals with the description of the historical development of childrens’ cars from the first manufactured models to modern pedal and electric carts. The next section describes the origin of cordless drills. The following section shows today's options for purchasing prams. The market has greatly enriched, and it is practically impossible not to choose. The construction part is focused on the design of individual components and a list of purchased parts. It also includes basic calculations for the selected chain and the designed structure.

Chain Drive for Valvetrains
Vodička, Richard ; Píštěk, Václav (referee) ; Novotný, Pavel (advisor)
The objective of this bachelor‘s thesis is obtaining the general review about the way of driving valvetrains. Introduction is devoting the driving of distributive mechanism of combustion engines . The text of bachelor‘s thesis is splitted on three parts. The first part is explaining the principle of functioning enginetrain. Briefly are described individual assembling of ventil distributor of engines and its distinction depending on the way of its drive. The main attention is devoted to the chain drive of valvetrain, i.e. distinction of types chain drive, which are necessary for its correct functioning. And also, are described the main parts of valvetrain of the engine and the other possibilities of its driving. The second part of bachelor‘s thesis is comparising positives and negatives of chain drives of valvetrains with the othe one’s. In the third part of bachelor‘s thesis are presented the examples of application of the chain drives in the valvetrains in the four wheel drives machines, cars and motorcycles. In the conclusions is specified the contribution of the chain drive of valvetrains and evaluation of bachelor‘s thesis.

Stacking palletizer of the food crates
Bajdich, Matej ; Jorda, Vladimír (referee) ; Pokorný, Přemysl (advisor)
The diploma thesis is focused on the food crates stacking palletizer construction design according to required values. In the first part of diploma thesis, it looks at the definitions and basic information about palletization, types of palletizers and describes analogous construction solutions of the given machine from other manufacturers. The second part, the diploma thesis deals with the designs of the own machine, their evaluation and designing of the own palletizer. Part of the palletizer design are calculations and numerical simulation of stress and deformation of the main frame of the machine at maximum load using the finite element method. The last part of the thesis deals with the evaluation of created palletizer design. The diploma thesis contains drawing documentation of selected sections.

Roll assembly system for automatic strapping
Havelka, Michal ; Marek, Tomáš (referee) ; Knoflíček, Radek (advisor)
This bachelor’s thesis is dealing with the design of system for rolls of technical textiles, which assembles them into horizontal layer. Possible structural drafts are mentioned here and one selected draft is solved. For the first I am dealing with major dimensions, the choice of rollers, calculation of the required engine power and the calculation of the chain drive. Finally I calculated pneumatic cylinders and checked the deflection of used rollers.

Design of elevator for pallets
Hájek, Lukáš ; Winkler, Tomáš (referee) ; Škopán, Miroslav (advisor)
The diploma thesis is focused on the construction design of elevator for pallets with car seats weighing 200 kg. This device is proposed for vertical transport of the load between two working positions which are separated by 6m. Part of the pallet hoist is a roller conveyor attached on a lifting frame. The roller conveyor allows loading and unloading pallets from the fixed roller conveyors in the lower and upper station. There are the functional calculations of important parts, strength control of traction belt and shaft of driving pulley drum. By FEM (Finite Element Method) is detected stress distribution of the lifting frame. Parts of the annex are the manufacturing drawings of the lifting frame, shaft of driving drum, the driving station and drawing of the whole assembly vertical conveyor. Furthermore, the timing diagram function for one cycle, risk analysis and FMEA.

Design of a hand-lever draisine
Uhrovič, Jakub ; Otipka, Václav (referee) ; Rekem, Jakub (advisor)
The thesis focuses on the design and construction of a hand lever draisine, which, upon completion, is intended to serve as a tourist attraction at the KŽM Vrútky museum in Martin, Slovakia. The first part of the thesis gives brief information about the history and purpose of hand lever draisines and describes their construction. The second part of the thesis focuses on the actual design of the proposed solution and utilizing the information gathered in the first part. It provides a detailed description of the individual design solutions for the draisine. In the third part, the force actions on the elements of the mechanism are investigated. Subsequently, the strength characteristics of the selected parts are verified using analytical calculation methods. Finally, in accordance with the requirements, a drawing documentation of specific parts is prepared.
