Malý axiální motor pro čerpadlo / Small axial magnetic flux motor for pump

Lacina, David January 2017 (has links)
This thesis aims to design a motor with axial magnetic flux, which could be used as a direct propeller of heart replacement pump. It is divided into several parts, first of which deals with describing possible axial motors construction design. Next follows up the description of possible motor designs, from which the non-ferrous one was chosen. After that, an analytic calculation of motor’s properties is conducted. Calculated parameters are thereafter verified by software tools using finite element method. Finally, the whole motor was manufactured and had its parameters tested and verified.

Obrábění součástí v malosériové výrobě s aplikací CNC strojů / Machining of parts in low series production with CNC machine application

Vaverka, Jiří January 2017 (has links)
The topic of this thesis is the choice of optimal production technology for the chosen representative. The aim of this work is to compare production on conventional machine and on NC and CNC machines. Both variants are evaluated in terms of efficiency, speed and economy of production. Outputs are based on recommended production procedures based on the number of pieces produced in the order.

Konstrukce jednoúčelového stroje pro broušení cihel LI CRETE / Construction of single-purpose machine for grinding bricks LI CRETE

Hubálek, Tomáš January 2017 (has links)
The aim of this thesis is to design a one-purpose machine for grinding concrete light-permeable bricks LiCrete. The bricks LiCrete are a new interior design component. The final step of manufacturing is wet grinding with high quality and accuracy. At the same time it is grinded the concrete and light-permeable parts made by polymethylmethacrylate (PMMA). It is important to keep size and quality appearance of the bricks. The research part contains description of the problems related to the grinding of the bricks LiCrete. The next part is about conceptual variants of the solution. The construction contains the complex solution of one-purpose machine with technical drawings. The last part include a conceptual design of continuous high-productive machine for grinding LiCrete bricks.

Výroba bezešvých kruhů technologií radiálně-axiálního válcování / Production of seamless rings by technology radial-axial rolling

Zapletalová, Martina January 2017 (has links)
The thesis is focused on the production of a seamless ring manufactured from low-alloyed steel 15 142, which fills the function as a large-dimensional bearing. On the basis of suitable production technologies analysis, the radial axial rolling method was chosen and a specific manufacturing process was proposed. During the manufacturing time, the creation of the forging defects in the transfers forms were occurred, which was totally undesirable. By changing the parameters of the machine, in particular the rolling curve and the temperature, the process was optimized and the production performed completely without defects.

Software pro zpracování dat a řízení CNC obráběcího stroje / Software for Data Processing and Control of CNC Machine

Kraicinger, Lukáš January 2017 (has links)
The thesis focuses on the design and impelementation of a control system for a CNC machine producing gears with specific integrated CAM system. The study includes practical verification of system functionality, which includes the design and creation of an electronic circuit on this machine. A prototype of a 6-axis machine is being developed at the Faculty of Mechanical Engineering BUT in Brno as a master thesis simultaneously with the creation of this term project. It is a compact automated gear producing machine (all in one) which requires only appropriate semifinished product and correctly set parameters of teeth using the touch screen on the machine.

Návrh výrobní technologie ozubeného hřídele převodovky / Design of production technology for a pinion shaft of a gearbox

Hulvej, Matúš January 2018 (has links)
The diploma thesis presents a design of a technical project: design of production technology for a pinion shaft of a gearbox and design of alternative technology. It focuses on the analysis of a component, the selection of materials, machines and tools, and the creation of a manufacturing drawing and technological process of the production. It is concluded by a technical-economic evaluation, based on which are both designs compared and evaluated which design is better for specific conditions.

Design pracovního stroje pro zhutňování krajnic / Design of the Machine for a Roadside Compacting

Šoltysová, Michaela January 2018 (has links)
Subject of this master thesis deals with the concept of the machine for a roadside compacting. After analysing of current market situation the aim of this work is not only to replace the vibration plate by new machine with a cab and vibration rollers but also mainly the design of the machine. The reason is easier work and it fulfils all constructional and ergonomic requirements and puts emphasis on aesthetic. So it fills a gap in the market.
