Design methodology for the selection of basic components of linear machine tool axes
Král, Stanislav ; Dosedla, Michal (referee) ; Holub, Michal (advisor)
The aim of the thesis is based on specified parameters positioning units, which include stroke (1m, 2m, 4m), load (5kg, 50kg, 500kg), you place the position accuracy (0.04 mm) and dynamic (maximum attainable speed 1.5 m / s), proposals to build a ball screw, linear motor, a toothed belt and toothed comb. For selected variants of positioning units to design a 3D model of positioning units. The proposed variations to compare and define their advantages / disadvantages, techno-economic comparison, the limit values of individual designs, etc. The work includes a search drive in positioning units, design units with toothed belt, a toothed comb, ball screw linear actuator, a calculated message of individual proposals then 3D design options for the ball screw and linear motor including drawings and assembly drawings.
Design of feed box X axis
Imrich, David ; Pavlík, Jan (referee) ; Holub, Michal (advisor)
The subject of this thesis is design of feed box for axis x of portal milling machine center FRP 300 from production of TOS Kuřim-OS, a.s. Thesis contains recherche in application field of rack and pinion drives for machine tools feed mechanisms, possible design solutions of given task and elaborate of the most appropriate solution. Thesis further includes calculations, 3D model and drawings of selected parts.
The design of plate horizontal boring mill
Vondrák, Pavel ; Holub, Michal (referee) ; Pavlík, Jan (advisor)
This master's thesis describes a design of horizontal boring mills. The first part is dedicated to description of the various types of these machines and their accessories. There are also described drives and linear guideways. There is a list of plate horizontal boring mills of Czech and foreign producers. The second part of this thesis deals with designing of comlete machine's bed and its slides (X-axis). Casting of the bed and its slides are designed for universal machining to the use of rolling or hydrostatic guideways. The drive of X-axis is also designed and it works in master/slave mode. The final result of this master's thesis is a 3D model of the machine in two variants, with hydrostatic and rolling quideways. Machining drawings of the bed for both variants are attached to this thesis.
Ejection mechanism automotive starter pinion
Sláma, Miloslav ; Janda, Marcel (referee) ; Hájek, Vítězslav (advisor)
The thesis describes ways ejection pinions automotive starter and evaluation of the advantages and disadvantages of each solution. The first chapter deals with the principle of operation of DC motors and starters parameters. In the second part, the individual systems are theoretically discussed in terms of design and their advantages and disadvantages. The third part is focused on the most common system, which is analyzed in terms of mechanical and electrical reliability. The last point of the work is to design an experimental analysis Reach starter pinion.
Drop forging of pinion
Cvrček, Jan ; Dvořák, Milan (referee) ; Štroner, Marek (advisor)
The final project has been elaborated in a frame of Bachelor’s studies branch Manufacturing technology assesses design of production pinion by method of die forging. The pinion is manufactured from alloyed structural steel 14 220 (1.7131). Size of production is set on 100 000 pieces per year. The pinion will be forged on the vertical forging press LMZ 1000 A with forming force 10 MN. The forging is formed in two operations. Forming tool is manufactured from alloyed instrumental steel 19 552 (1.2343). In the last chapter of the project is described the price comparison and costs for manufacture of die forging and machining.
Drop forging of pinion
Kameník, Tomáš ; Dvořák, Milan (referee) ; Štroner, Marek (advisor)
KAMENÍK Tomáš: Drop forging of pinion The project has been elaborated within the framework of studies of the subject B 2307 and it presents the lay-out of the technology of the forging – the pinion which is made as the drop forging from the material 14 220. The rougher and the finishing forging die were suggested on the bases of the literature study of the drop forging. In consideration of the big series /100 000 pieces/ and the calculated forging power /25MN/ the component will be made on the vertical forging press LZK 2500P/SH (the manufacturer ŠMERAL Brno a.s.). At the end of the thesis there are performed calculations of the technical and economic evaluation.
Drop forging of pinion
Sklenář, Zdeněk ; Kopřiva, Miloslav (referee) ; Štroner, Marek (advisor)
The literary study of production of pinion with drop forging of metal 14 220 is proposal in the final project. The literary study includes knowledge from metal hot forming. With regard to high production of 190 000 pieces for year was choosen the technology of drop forging. The vertical forging press LMZ 1600 (made by ŠMERAL Brno a.s.) was choosen for proposal technology.
