The invention relates to a planetary gear intended to reduce/amplify the rotation speed of a driving element. According to the invention, the planetary gear has an eccentric shaft (a) on which there are articulated two chain wheels (1 and 1') integral to each other, having the role of a double satellite which, on the one hand, engages with a double chain wheel (3) by means of a multiple chain (2) and, on the other hand, engages with another double chain wheel (5) by means of another multiple chain (4), the chain wheels (3 and 5) being placed on either side of the two satellite chain wheels (1 and 1'), coaxially with the eccentric shaft (a). |
