Bevel gearbox design for heavy industrial applications
Škopec, Filip ; Vlašic, František (referee) ; Svoboda, Petr (advisor)
The thesis deals with the problem of bevel gearboxes on the Czech and foreign markets, where there is no offer in a wider range of required properties and specifications. The main goal of the thesis was to devise a design solution for a two-stage bevel gearbox for belt conveyor mine operation with parameters: P=37 kW, n=1450 rpm, i=20 and operation in a dusty environment. Based on the analysis of the current state of knowledge, which dealt with the main components of bevel gearboxes, four conceptual solutions were created from the point of view of the arrangement of individual gears. From the individual comparisons of the appropriateness of the use of the given conceptual designs, a design with a modified gear-case was selected, which was processed using design calculations and subsequently checked by strength calculations. The output of this thesis is processed production drawings of shafts, bevel and spur gear and then a drawing of the bevel gearbox assembly. The thesis also includes a written general procedure for the design of bevel gearboxes, which can serve as a guide for readers. The resulting construction design can form the basis for the final product of companies that would deal with a potential order.
Scooter powered by cordless drill
Šimo, Samuel ; Böhm, Michael (referee) ; Štětina, Josef (advisor)
This bachelor thesis analyses the problematics of scooters with additional driving force and new opportunities in usage of unconventional methods of propulsion. The first part describes history and early development of prototypes. Then it reports on current legislative regulations in road traffic. The second part comments on design procedure of cordless drill - powered scooter with detailed description of used components.
