Avantprojecte d'una roda intercanviable per a cadira de rodes d'accionament manual amb tres velocitats

Abstract

En aquest projecte es realitza el disseny d’una roda per a cadira de rodes manual que incorpora un mecanisme que permet variar la relació de transmissió entre la corona d’impulsió i la roda. Aquesta, a més a més, s’ha dissenyat intercanviable per tal de fer-la adaptable a qualsevol cadira. El treball inclou un estat de l’art en el qual s’explica els diferents tipus de cadira de rodes disponibles al mercat i el mecanisme Sturmey Archer, un canvi per a bicicletes que realitza una funció similar al canvi dissenyat en aquest treball. El disseny segueix les etapes: anàlisi dinàmica i selecció de la transmissió adient, càlcul de la sol·licitació dels elements més crítics per assegurar que no fallen durant el funcionament i anàlisi per elements finits per decidir el nombre de radis a incorporar a l’anella d’impulsió, així com el disseny al detall i els plànols d’algunes de les peces més importants. Finalment es duu a terme una anàlisi del cost de la fabricació d’un prototip i l’impacte ambiental que aquest tindria al llarg de tota la seva vida útil.
