Abstract
A device for transforming motion, and in particular a speed reduction gear, comprises a first stage comprising two moving members (50, 60) at least one of which is functionally coupled to a shaft (74) generating a rotary motion; a second stage comprising at least one set of two pulleys (54, 54) constrained to rotate together, and co-operating with respective transmission means, for example two endless drive strands (52, 64) which co-operate with the moving members of the first stage; and a moving support (26) which supports the two pulleys of the second stage to rotate freely and which is displaced over an imposed trajectory, thereby generating a second motion, with the first motion being a high speed motion and the second motion being a slow motion.
