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.
Manufacturing of Gearwheels Using Various Technologies
Řezáč, Matěj ; Prokop, Jaroslav (referee) ; Kalivoda, Milan (advisor)
The present bachelor thesis is focused on the production of spur gears. The theoretical part summarizes the information related to toothing, its production and inspection. In the practical part, three technologies of spur gear manufacture are selected the gears are made. Finally the thesis compares the spur gears produced by these technologies geometrically and dimensionally
