Design of acceleration head spindle horizontal boring machines
Tocháček, Jakub ; Vetiška, Jan (referee) ; Holub, Michal (advisor)
This thesis deals with conceptual design of spindle speeder head for headstock of horizontal boring machine of FERMAT Company. The thesis includes research part, which is initially given to horizontal boring machines and their accessories and continues with an overview and comparison of spindle speeders that are currently on the market. The work includes technical report, which is aimed on design of the belt drive including the idler pulley. Design of belt drive is based on the output of the calculation program developed by manufacturer of synchronous belts. Calculation part, mainly focused on the spindle and its bearings, is preceded by a part in which are calculated cutting forces for two technological operations. Calculation of the spindle part contains strength calculation of the spindle and equivalent basic rating life of spindle bearings, including calculating of radial stiffness at the spindle nose and calculation of optimal distance between the spindle bearings. At the end of the technical report is a financial summary, description of used components and the chosen design solution. The drawings which are based on model assembly processed in 3D CAD system, contains a drawing of the entire device and drawings of selected components.

The screw conveyor of aggregate
Tocháček, Jakub ; Pokorný, Přemysl (referee) ; Kašpárek, Jaroslav (advisor)
This bachelor thesis deals with the conceptual design of horizontal screw conveyor for transportation of aggregate. The work consists of technical report and drawings. Technical report contains the calculation of main dimensions, selection of the drive, clutch and bearings, including stress analysis of functional parts. The drawings, which are based on model assembly processed in 3D CAD system, contains a drawing of the entire device, sub-assemblies of bearing seats and welding subassembly of trough.
