Production of pinion
Matsiuk, Oleksandra ; Lidmila, Zdeněk (referee) ; Podaný, Kamil (advisor)
The bachelor's thesis deals with the design of the production of pinion – small gear made of steel 14 220. After analyzing all possible production methods, the technology of die forging on a hammer in the single-die was chosen. Based on a literature study of the issue and relevant calculations, a semi-finished product with a length of 151,8 mm and a diameter of 63 mm was designed. Hammer KHZ 4A with forming energy of 50 kJ was chosen. A single-die was constructed on the basis of valid state standards. Auxiliary machines were also chosen for production – band saw, induction heater, shearing press and drum blaster.

The drive of the feed coordinate portal machining center using a rack and pinion
Bartoš, Michal ; Knoflíček, Radek (referee) ; Marek, Jiří (advisor)
This diploma thesis deals with the design the drive of the feed coordinate portal machining center using a gear rack and pinion. The thesis contains researches from the area of CNC machining centers for non-rotating parts and sliding linear systems. Market analysis of portal machining centers of type of lower gantry with a gear rack and pinion was done. Furthermore, several design variants are proposed in terms of positioning the drive on the machine. These variants were further compared and the best option was selected for the specified machine. Subsequently, the technical calculation of the drive is performed and individual parameters and structural elements are proposed. The thesis also includes a 3D model of the proposed variant and the required drawing documentation.

Transmission error in spur gears
Bartošová, Daniela ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
This master’s thesis is deal with the area of determining the static transmission error in spur gears. Nowadays, around vibration and noise formation, the issue of transmission error is being discussed quite often. In the first part of this master’s thesis, there is a description of the theoretical requirements concerning the above stated issue. These theoretical requirements are further applied in parametric planning of the spur gears as well as in measuring the transmission error itself. In this master’s thesis, both the detailed description of planning the parametric model of spur gears and the strain-stress analysis may be found. These requirements are needed for calculating the transmission error. In conclusion of this master’s thesis, specific results of the static transmission error in spur gears achieved at diversifying load torque, center distance modifications as well as tip relief modifications of spur gears are being presented. The issue was solved by computation approach with the help of CAD software called Creo Parametric and FEM software called Ansys Workbench and Ansys Mechanical APDL.

Production of pinion
Vališ, Ondřej ; Štroner, Marek (referee) ; Císařová, Michaela (advisor)
The bachelor thesis deals with literature study of cold forming technology. Further the thesis submits a proposal of the production technology of pinion into the gearbox of passenger vehicles made from alloy steel according to ČSN 16 326. Thanks to knowledges aquired by literary study of bulk forming issue was suggested a direct extrusion technology with consequential cold upsetting. The component part will be produced in two production processes and series of fifty thousand pieces per year. These manufacturing processes will be used on forming machine called Schuler with nominal force of two thousand tons which is part of Metaldyne Oslavany company involved in automative industry.

Service platform of boring machine
Šebela, Michal ; Hulánek, Martin (referee) ; Brandejs, Jan (advisor)
The Diploma’s thesis deals with a construction design of a service platform for a horizontal boring machine. Input parameters are cabin dimensions, length and velocity of lift and shift. In the first part of the thesis is design arrangement solved. The lift is solved by a rack and a pinion. By the lift is drive design and gear calculation performed. Shift of the service platform is done by toothed belt. Air distribution with pneumatic parts choice is included in this thesis. Next part is divided to supporting frame and cabin design. It is made by welded profiles, in which a stress-strength analysis is performed. The last part of the thesis is divided to linear guide design. A part of this thesis is a drawing of an assembly facility and a movie about this service platform in a real service.
