Production of short shaft by extrusion
Hondl, Jiří ; Šlais, Miroslav (referee) ; Forejt, Milan (advisor)
HONDL Jiří: Production of short shaft by extrusion. The project prepared as part of the Master-degree studies in the Engineering technology concerns the technology design for manufacturing a short shaft by extrusion. On the basis of the study cold forming methods and problems and following technical calculations was designed a four steps process of forming. Semifinished product has a cylinder shape with a diameter of 18mm and a length of 51,2mm. The production is designed for automatic multistage press TPZK 25 with nominal pressing force of 5 000kN from Czech producer and supplier of machinery Šmeral Brno company. Tools are made of tool steel, extrusion punch and extrusion die is designed of 19 830.4 steel, and extrusion die´s band is designed of 19 733.4 steel. Tools are designed to be improved by hardening and drawing.

Gearbox for portable power generator
Kolka, Roman ; Hubáček,, Tomáš (referee) ; Bradáč, František (advisor)
The submitted project deals with a complete design of a gearbox of a portable ground power generator designed for preflight preparation of helicopters. The gearbox has been designed to meet given specifications, which are based on required electrical parameters of the entire power unit and with regards to parameters of driving turbine engine. The introductory section deals with a kinematical design of transmission gears with regards to required parameters and design constraints. The kinematical design determines whole concept and resulting form of the gearbox. Next part deals with optimization of gearing, the design of wheel bearing, and design of oil system. The implementation part of the project consists in the engineering design of the gearbox, which was made in 3D environment Pro/Engineer. The design is reviewed and first operational results of manufactured and tested gearbox are discussed in the concluding section of this work.
