Konceptutveckling av fyllda balanser

Detta är en Kandidat-uppsats från Högskolan i Jönköping/JTH, Maskinteknik; Högskolan i Jönköping/JTH, Maskinteknik


This examination project has been performed in collaboration with Husqvarna AB, one of the world’s leading manufacturers of both commercial and professional garden products such as chainsaws, trimmers and lawnmowers. Husqvarna AB always strive to develop and improve new and existing products and components to ensure an attractive product and a competitive position on today’s market


One of these components is filled balances. This is a component unique to the company and is one of the parts in their fuel-powered chainsaws. This component is placed on the crankshaft to increase compression in the crankcase, hence increasing the power of the chainsaw. The problem with the product today is the constantly changing fit on the weights and the complexity of the manufacturing process.


The examination contains the conceptual development of these filled balances with the goal to contribute with several realizable concepts that solve these problems and simultaneously increase the products durability.


This report describes the conceptual process and walks the reader threw the necessary steps that finally leads to a finished concept. The report describes the theories and softwares used in this project and how they were used to end up with two finished conceptual solutions.


The final results are presented at the end of the report with images of the final concepts, simulations and the conclusions this report lead to.
