Abstract

L'invention porte sur une nouvelle scie alternative qui comporte une poignée (1), un commutateur (2), une ligne d'alimentation (3), un moteur (4), un boîtier gauche (5) et un boîtier droit (6), et qui comporte de plus une première lame de scie (8), une seconde lame de scie (9), un support supérieur (10), un support inférieur (11) et, disposés entre le support supérieur (10) et le support inférieur (11), un engrenage supérieur (12), un premier arbre excentré (13), un premier bras d'entraînement (14), un engrenage inférieur (15), un second arbre excentré (16) et un second arbre d'entraînement (17). Un grand nombre de pièces de la scie alternative sont universelles, et un grand nombre des surfaces de montage sont usinées en place par un centre d'usinage directement sur un moulage en aluminium (ou en alliage de magnésium), réduisant le nombre et le type de parties assemblées. De plus, des facteurs d'usinage sont pris en compte lors de la conception, de telle sorte que l'usinage de toutes les surfaces de montage peut être achevé en une seule étape. En outre, le premier bras d'entraînement et le second bras d'entraînement sont directement entraînés par une paire d'engrenages coniques en spirale, réduisant une perte de rendement provoquée par un entraînement à deux étages ou à étages multiples. La présente invention réduit la longueur de la scie alternative et simplifie l'assemblage, de façon à fournir une structure plus compacte, un plus faible poids et un coût de fabrication global considérablement réduit.
