Abstract

Tema rada je preinaka postojeće izvedbe mjenjača brzina mopeda Tomos. U standardnoj izvedbi moped ima 5 brzina, a preinaka će biti izvedena na 7 brzina. U početku će biti rečeno nešto o Tomosu kao proizvođaču i njegovoj povijesti. Zatim će se prikazati računalno simulirani dijagram snage motora te odabrani novi prijenosni omjeri koristeći se adekvatnim pilastim dijagramom.

Središnji dio ovog rada je proračun mjenjača, odnosno parova zupčanika, prema ISO 6336 metodi B, te proračun vratila. Proračunat će se još i potreban stezni spoj te će za analizu naprezanja gonjenog vratila biti korištena FEM analiza.

Komponente mjenjača i postojeće kućište motora modelirani su u programskom paketu Autodesk Inventor te je u njemu napravljena i priložena tehnička dokumentacija. Programski paket Abaqus je korišten za FEM analizu.

Na kraju rada slijedi zaključak kao osvrt na problematiku adaptacije postojećih tehničkih rješenja.

Abstract (english)

The subject of this thesis is the adaptation of an existing version of a Tomos moped gearbox. The standard version is a 5-speed gearbox, while after adaptation it will be a 7-speed gearbox. In the beginning, you willl learn about Tomos as a manufacturer and its history. You will then see a computer-simulated diagram of engine power and selected new gear ratios using the appropriate slope diagram.

The central part of this thesis is the calculation of the gearbox, respectively gear pairs, according to the ISO 6336 method B, and the calculation of shafts. There will also be calculations of the required clamp connection and an FEM analysis will be used for stress analysis of the driven shaft.

The components of the gearbox and the existing motor housing are modeled in Autodesk Inventor software package which was also used to provide the technical documentation. Abaqus software package is used for FEM analysis.

In the end of this thesis, there will be the conclusion as a reference to the issues of adaptation of the existing technical solutions.
