Rekonstrukce převodovky pro retardér vozidla Tatra 815

Abstract

This master thesis deals with the analysis and design modifications of a gearbox for a Truck Tatra 815 retarder. The first part presents the overview of the commonly used retarders (brakes). The main content of the thesis is the assessment of the condition of the gearbox including analysis of the gears using the software and design of possible modifications for improved operational properties. In the next part are done calculations of the forces emerging in the gears which are used for determination of the durability of bearings. In the last part is done a calculation of the static and dynamic safety coefficient of the output shaft of the gearbox. The 3D model which is used for the creation of drawings is created in the Autodesk Inventor 2015.
