Design of coaxial high-speed gear reducer
Neklapil, Libor ; Ing. Tomáš Hubáček, Ph.D (referee) ; Bradáč, František (advisor)
The thesis deal with design of coaxial high-speed gear box for small-scale turboshaft engines. At the beginning a study of problems was performed and for design concept was elected version of single-shaft turbo-engine with electric generator. Kinematic diagram, type of gear design, material and lubrication method was designed. Further was solved proposal of basic gearing parameters, choice of the number of tooth and basic proposal calculations were performed. Was performed check calculation of gearing, calculation of bearings durability and was processed design documentation in required range. Designed gear reducer has two stage with three coutershafts, that are deployed evenly about main axis of reducer. First stage is gear with external gearing, second stage with internal gearing. The thesis may be used as a template for next similar gear reducers design.

Innovation of production process of the shaft for an auxiliary power unit
Dubovský, Jakub ; Sliwková, Petra (referee) ; Píška, Miroslav (advisor)
This thesis presents a proposal for a new technology for the production of a shaft component, which is located in the internal system of an auxiliary power unit designed for helicopters. In the first part, an evaluation of the component and the relation of its design to the functional requirements placed on the component in the device is carried out. This is followed by an analysis of the component material and process manufacturing influences. In particular, the heat treatment of the material and the nitriding process performed on the shaft. Following the assessment of the original state of production, options for a new production technology of the component are proposed using the capabilities of the new machinery in the company. After the evaluation of the proposed technological solutions, the selected variant of the production process is verified by a test production series, which declares the applicability of the proposed technology for deployment within the standard production mode. The paper concludes with a technical and economic overview.
