Production sprocket
Diviš, Adam ; Štroner, Marek (referee) ; Lidmila, Zdeněk (advisor)
The project elaborated design of technology production of the sprocket using die forging from steel C45. Pursuant to of the literary pursuit a problem of the die forging and calculation was designed manufacturing process for three operations. Dimensions of forging and tool are designed according to appropriate standards. Forging will be done on forging press LZK 1000 P/SH, with nominal tensile force 10 MN. Dies will be made from instrumental steel 19 662 heat-worked according to drawing documentation.

Project of service lift
Drápela, Josef ; Malach, František (referee) ; Malášek, Jiří (advisor)
This diploma thesis deal with project of service lift. The service lift is drive by special mechanism using thrust chain. The chain is led from chain accumulator over sprocket gear to vertical guiding groove. Lift car is connected to the end of chain. There are designed and described the most important constructional unit of service lift in this thesis. But the most attention is pay to drive, including break system and chain accumulator. The drive is consist of electric motor, clutch, break, planetary gearbox and sprocket gear.

Design of manipulator for palletization
Florián, Michal ; Pochylý, Aleš (referee) ; Kubela, Tomáš (advisor)
The matter of this master´s thesis is the construction of two variations of manipulator for palletization. The first solution is the derrick manipulator; the second one is the gantry manipulator. The aim of this master´s thesis is the comparison of both solutions from the point of view of the applicability, the cost and the demandingness of production. The productinon documentation will be elaborated for the selected solution.

Forging of rotary forgings
Konvalina, Michal ; Štroner, Marek (referee) ; Lidmila, Zdeněk (advisor)
The thesis is focused on manufacturing proposal of the conveyor chain sprocket using die forging from steel C45 (12 050). Based on the literature review of eligible technologies, volume termoforming technolology has been selected here, more accurately closed die forging on a vertical crank forging press with an open flash gutter. Dimensions of forging and die are designed according to appropriate valid standards. Based on calculated tensile force of 10,83 MN will be forging performed on vertical forging press LZK 1600 P/SH. Forging die will be made of low alloy tool steel 1.2713 (19 662) and ejection of forging will be executed by three ejector pins in lower and upper finishing die.

Manufacturing of the Motorcycle Rosette
Radnický, František ; Peterková, Eva (referee) ; Řiháček, Jan (advisor)
This bachelor thesis is focused on design of suitable technology of motorcycle sprocket, made from sheet metal 11 500 with a thickness of 6 mm. The production series of this component is 100 000 pieces per year. Before selecting the most suitable technology for the production of rosette the evaluation of different available technologies was carried out, of which as the most appropriate method, the accurate cutting with pressing edge is selected. The technological and constructional solution is elaborated, which involves selecting of the appropriate blank (sheet metal 6 x 2000 x 4000), design of cuttingg tool with its documentation and the choice of production machine triple-action hydraulic press Feintool HFA 11000 plus. In the final phase, a technical and economic evaluation of the efficiency of the production is performed.

Differential tackle
Valach, Petr ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
This bachelor’s thesis deals with the calculation and construction proposal of self-locking differential tackle with lifting capacity of 600 kg and lift of 3.7 m. After a short division of tackles according to various criteria and their description is followed by a more detailed description of the chosen construction of the differential tackle. The thesis includes the calculation of the sprockets according to the relevant norm, the choice of the chain, bearing selection, assessment limits and safety self-locking and important strength calculations taking into account the manual manipulation. There is the drawing documentation according to the topic of the bachelor’s thesis.
