Production of sleeper screw
Bartošek, Filip ; Štroner, Marek (referee) ; Lidmila, Zdeněk (advisor)
Bachelor thesis developed in the bachelor degrees addresses technological process of the production sleeper screw. The production uses technology volume thermoforming. The project was elaborated in cooperation with the company ŠROUBÁRNA KYJOV s.r.o. The screw will be made from material ČSN 11 503. This material is unalloyed construction steel with property of weld. Based on the literature study technology volume thermoforming was chosen tamping in closed instrument for the production of head screw. For the production of screw-thread was chosen technology of rolling. For the production head of screw was chosen horizontal fitting press machine. After the production there were used surfacing by galvanic zinc coating because of the better corrosion resistance.
Quality of The Track Geometry Progress
Peňázová, Gabriela ; Volejník, Miloslav (referee) ; Svoboda, Richard (advisor)
The bachelor’s thesis deals with the development of track geometry over the course of time. The first part describes current system of measuring and evaluating of track geometry. The second part uses the described system on the specified track section of the double-track line Hodonín-Rohatec. The measured data provided by SŽDC are evaluated and compared with the track maintenance work. For the chosen sections the exponential and linear functions for the development of longitudinal elevation were established and we judge the possibility of using them for the prediction of track quality development.
Vsetin - Velke Karlovice Railway Track Refurbishment (section between km 2.725 - 6.000 km) Including Track Laying Technology
Klar, Vít ; Hoza, Miroslav (referee) ; Říha, Tomáš (advisor)
This thesis deals with the design of track geometry parameters and the reconstruction of the selected section of Vsetín – Velké Karlovice railway track’s superstructure. This reconstruction expands to further include the connection track to the Bečva branch. This proposal has been designed with the following objects in mind: railway stops Ústí u Vsetína and Janová, railway crossings, bridges, culverts, etc. Finally, this proposal addresses the restoration of drainage along the tracks and track laying technology. It should be noted, that all proposed adjustments are designed according to current regulations and legislation.
Manufacturing of a Pin
Glatter, Jiří ; Forejt, Milan (referee) ; Řiháček, Jan (advisor)
The work presents a proposal for the technology of production of a pin of gear assambly.The pin is used to position the wheel in a tapered roller bearing. Pin is made of 11 320.3 steel (11 320 5R), which is suitable for cold forming. Based on the study of cold forming and calculations, the methods of upsetting and extrusion were chosen. Most often, several methods are used for fabrication, which are mediated by a combined tool. It can also be made by any of the machining methods.
