Press LKJP 630
Haman, Tomáš ; Ptáček, Libor (referee) ; Omes, Jiří (advisor)
Master’s thesis deals with the design of the drive of the press LKJP 630, the configuration is a fixed range by the construction of LKJP. The thesis was ordered by partnership with company ŽĎAS, which is introduced. The first part is devoted to analysis of solved problems, it primarily contains the overview on forming machines, used drives and a description of their main parts. The second part deals with the drive itself, there is accomplished the design and performed the strength analysis of the major parts of the drive. Drawing documentation and bill of materials are included.
Planetary Gear Box Used for Drive Table of Vertical Lathe Driven by the Direct Drive Engine
Žila, Slavomil ; TOSHULIN, Milan Lutonstý, (referee) ; Novotný, Lubomír (advisor)
The main theme of this thesis is an analysis, desing and construction of a planetary gearbox used for a drive of a vertical lathe table. The theoretical part of the thesis describes fundamental features and terms of planetary gearboxes and torque motors. In the next part of my work I design loose functioning of toothing. The calculation part of my work is processed in accordance with technical standards. The practical part of my work deals with a description of the project and the implementation of the device. The drawing documentation is processed with Cad system and it includes general assembly drawing and drawings of the three important components.
Project of service lift
Drápela, Josef ; Malach, František (referee) ; Malášek, Jiří (advisor)
This diploma thesis deal with project of service lift. The service lift is drive by special mechanism using thrust chain. The chain is led from chain accumulator over sprocket gear to vertical guiding groove. Lift car is connected to the end of chain. There are designed and described the most important constructional unit of service lift in this thesis. But the most attention is pay to drive, including break system and chain accumulator. The drive is consist of electric motor, clutch, break, planetary gearbox and sprocket gear.
Signal Analysis
Vávra, Pavel ; Keprt, Jiří (referee) ; Beneš, Petr (advisor)
This thesis deals with problem of analysis signal acquiring measurement of uniformity motion harmonic drive and planetary gearboxes. In introduction part are explain some features of FFT and concept of cepstrum. Further is present overview of most often measured parameters of these gearboxes and needed formulas, which express connections among particular mechanical parts of gearboxes. The next part deals with description of SW program unit generated in LabView environment, which is output product of work and makes analysis on measured courses.
Application of Fused Deposition Modelling Method to Production of Planetary Mechanism Model
Kudláčová, Barbora ; Kolář, Ladislav (referee) ; Sedlák, Josef (advisor)
This thesis aims to deal with designing and construction of the planetary mechanisms mod-el with using the technology of Rapid Prototyping. Virtual model was designed by para-metric program SolidWorks 2013 and produced by 3D printer called Dimension uPrint, which uses Fused Deposition Modeling for the production. The thesis also includes the description of the planetary mechanism especially from theoretical, practical and also construction knowledge. The thesis contains the description of Fused Deposition Modeling too. The model of planetary mechanism is using as an educational tool especially for students of BUT Faculty of Mechanical Engineering in the subject Kinematics.
Modern hybrid drive of passenger vehicles
Švoma, Jan ; Blaťák, Ondřej (referee) ; Vančura, Jan (advisor)
This bachelor thesis deals with the current hybrid-drives in passenger cars. The thesis contains the categorization of hybrid systems according to structure and use. It also discusses the analysis of individual components and describes their suitability for use in different situations. It is focused on current offering of hybrid vehicles and development opportunities. At the end of are evaluated economic aspects and prospects for the use of these systems in the future.
Recovery winch for mobile machinen
Tichý, Štěpán ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
Bachelor’s thesis deals with design rope winch for mobile machines with a maximum pulling force of 20000 N. The work consists of technical report and drawings. Technical report includes a search of the current solution, designs and controls rope, rope drum, electromotor, gearbox and bearings. Next the work includes custom design of semiautomatic mechanical clutch with the calculation components of which it is composed. Design documentation includes component drawing and drawing the rope drum.
Dynamic model of planetary gearbox with braked satellite-gear carrier
Půst, Ladislav ; Pešek, Luděk ; Radolfová, Alena
The report is focused on theoretical-numerical analysis of influence of flexible planetary pins and of planetary gearbox connection with external driving and braking aggregates. Introducing of the compliance of planetary pins and releasing of sun wheel requires complicated differential equations of motion containing new radial coordinates and negative radial stiffness of tooth mesh. Eigen-frequencies of separated gearbox and of three-aggregates-set are ascertain for different values of torsion stiffness of external aggregates. It was shown that there exist several multi-fold eigen-frequencies.
Dynamic model of planetary gearbox
Půst, Ladislav ; Pešek, Luděk ; Radolfová, Alena
Influence of planetary gears flexible pins on the dynamic properties of planetary gearing box is investigated. This flexibility of planets pins enable better power flow distribution in planet subsystems and increase the input torque density. Analysis of proposed simple mathematical model explains basic dynamical properties of planetary gearing with flexible pins, influence of pins’ stiffness on frequencies and on modes of free vibrations as well as on the response curves at external harmonic excitation.
Dynamic properties of driving systems - composite method of analysis
Chalupa, M. ; Kratochvíl, Ctirad ; Heriban, P. ; Kotek, Vladimír
The article contains the description of technical measurement application of hydraulic pressure in hydraulic control system of planetary gearbox with three freedom degrees and practical example of the modelling of the influence different courses control pressures on the quantity of dynamic load of toothed wheel of planetary gearbox mechanism. It is used the dynamic properties of driving systems composite method of analysis for the modelling.
