Abstract
A reducing device having a cable or a belt and cable, providing a high reduction ratio, and including: two driving drums; two sheave wheels; at least one driving cable traveling from a first driving drum to one sheave wheel, from the one sheave wheel to the second driving drum, from the second driving drum to the other sheave wheel, and from the other sheave wheel to the first driving drum; a driven cable, including one strand which travels from a fork of the one sheave wheel to a driven wheel, and one strand which travels from the driven wheel to a fork of the other sheave wheel. The driving drums have different diameters and/or different rotation speeds so rotation thereof causes movement of the sheave wheels driving the driven cable, and rotation movement of the driven wheel. The reducing device is applicable, for example, to robots and haptic interfaces.
