Analysis and design of elevator storage drive in the paint car bodies
Polášek, Lukáš ; Bukáček, Vladimír (referee) ; Dvořáček, Jiří (advisor)
The aim of this diploma thesis is making a degradation analysis of guide track for car body elevator and creating a new design of storage drive according to acquired knowledge. In the first part of this thesis is written research dealing with the issue of lifting equipment. Afrer this part follows load calculation with consideration of dynamic effects. Based of this calculation are created four different variants of the new travel lift with the use of various types of rollers (metal and plastic) moving through different types of rails (elevator and square profil). For most appropriate selected variant are created two differend designs of the new travel lift. Design variants are described in detail and check by finite element method, giving rise to the final selection of variants. For the selected variant is produced complete drawings.
Manufacturing of the engine oil tank cap
Polášek, Lukáš ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
The project introduces a technology design of an oil tank cap manufacturing for a turboschaft engine TV3 – 117MT of the MI – 17 helicopter. The component will be produced of DC04 material in a batch of 10 pieces per year. Based on the evaluation of possible production methods the rubber pad forming process with an uncertain instrument (Guerin Method) was chosen. A raw material of 112 mm diameter will be cut out from a metal sheet which dimension will be 1000 mm x 2000 mm x 1 mm. An versatile (universal) tool which is suitable for forming, cutting and bending is designed for a hydraulic press machine CTH 1000. It`s power is 10 000 kN and it is available in the Arial toolshop.
Special bearing types and its application
Polášek, Lukáš ; Vrbka, Martin (referee) ; Koutný, Daniel (advisor)
The goal of this bachelor’s thesis is to provide a search analysis of special bearing types. This work is focused especially to magnetic and air bearings, which are the most available and used special bearings. Both of these types are contactless, from which follows a big part their benefits. In this thesis there are introduced and explained the principles and design solutions of the most frequently used types of magnetic and air bearings. At the conclusion there are written up advantages and possible uses of these bearings.
