Manufacturing of chain wheel for BMX bike
Figar, Erik ; Peterková, Eva (referee) ; Řiháček, Jan (advisor)
The thesis deals with the design of suitable technology for the production of BMX sprocket made of sheet metal 14 220.3, with a thickness of 4 mm. The production series is 200,000 units per year. Following the analysis of different production options, fine-blanking technology has been chosen as the most suitable precision cutting technology. A technological proposal has been created, which includes the choice of a suitable appropriate blank (sheet metal 4x2000x6000 mm) as well as the design of a shearing tool with the corresponding drawing documentation of its selected parts. On the basis of the calculated values, HFA 4500 plus hydraulic triple action press manufactured by the Feintool company was selected as a production machine. In the last stage, technical and economic assessment of the efficiency of this production was performed.

Manufacturing of chain wheel for motorcycle
Šarocký, Robert ; Peterková, Eva (referee) ; Řiháček, Jan (advisor)
The aim of this thesis was to propose a suitable technology for the construction process of a chain wheel, which is one of the parts of the drivetrain of a motorcycle. The production series was 200 000 pieces per year. An analysis of several different construction processes was carried out and the process chosen as the most suitable was exact cutting with compression edge. The material of the product was a metal plate (8 x 1000 x 2000) mm 14 220.3, with the width 8 mm.Furthermore, a proposal of a cutting tool was conducted with drawn documentation. Based on the calculation of the required powers the manufacturing machine was chosen, more particularly the three way hydraulic press Feintool HFA 8800 plus. In the final phase, an assessment focused on the effectiveness of the production process was carried out with focus on both the technical and the economic standpoint.

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.

Project of special manipulator
Martinů, Jan ; Malach, František (referee) ; Malášek, Jiří (advisor)
This thesis describes the design of a special manipulator, driven by a special mechanism with a pushed chain. The chain is conducted from the bottom branch of a horizontal guide slot via a chain wheel to the upper branch of a guide slot. To the end of the chain there is connected a frame manipulator via a tap connection. In this work there are described and suggested the most important component units of a manipulator, including a drive.

Proposal production of a chain wheel with the unconventional methods of machining use
Mikeš, David ; Kubík, Roman (referee) ; Dvořák, Jaromír (advisor)
This bachelor thesis deals with the application of unconventional methods in machining (use of laser and hydro-abrasive beam) during chain wheel production. Firstly, the unconventional methods are divided according to the overwhelming effect of material separation, and then these methods are briefly described. In the second part of the thesis, you can find the technological process of chain wheel production with the usage of cutting operation method, which is followed by the assessment of production costs. Afterwards, the chain wheel is produced with the application of laser and hydro-abrasive beam. The final part of the thesis contains comparison between the unconventional methods and the conventional method of cutting operation. The comparison is based on the achieved structure of surface of the gear tooth, the production time and the economic point of view.
