Title (EN) MECHANISM FOR MUTUAL TRANSFORMATION OF RECIPROCATING AND ROTARY MOTIONS
(FR) MECANISME DE TRANSFORMATION MUTUELLE DE MOUVEMENTS DE VA-ET-VIENT ET ROTATIFS
Abstract:
(EN) In a casing (1) of the mechanism are coaxially mounted two links (2 and 3) pressed against each other and mutually engaging through balls (4) located between the butt-ends of these links (2, 3), facing each other and provided with an undulating circular surface (5). The link (2) is mounted rotatably and the other link (3) is mounted with the possibility of reciprocating motion. Each undulating circular surface (5) has a profile whose maximum rise angle exceeds half of the angle of sliding friction between the rolling bodies (4) and the undulating circular surfaces (5), and the maximum curvature of the wave through exceeds the maximum curvature of the wave top.
(FR) Dans une structure (1) du mécanisme sont montées coaxialement deux liaisons (2 et 3) poussées l'une contre l'autre et reliées mutuellement par l'intermédiaire de billes (4) situées entre les extrémités d'aboutement de ces liaisons (2, 3), tournées l'une contre l'autre et dotées d'une surface (5) circulaire ondulante. La liaison (2) est montée rotative et l'autre liaison (3) est montée de manière à pouvoir effectuer un mouvement de va-et-vient. Chaque surface (5) circulaire ondulante présente un profil dont l'angle de montée maximum dépasse la moitié de l'angle de frottement de glissement entre les corps roulants (4) et les surfaces (5) circulaires ondulantes, et la courbure maximum du creux de l'ondulation dépasse la courbure maximum du sommet de l'ondulation.
