FLEXIBLE-LINK DIFFERENTIAL MECHANISM WITH TWO SUSPENDED PULLEYS

Identical pulleys 1 and 4 rotate about fixed axes A and B. Identical pulleys 3 and 6 rotate about axes E and F of slide 9 which reciprocates in fixed guide a. Identical pulleys 2 and 5 rotate about axes C and D of link 7. Link 7 with pulleys 2 and 5 is freely suspended on endless flexible link 8 which runs over all six pulleys. When pulley 1 rotates about axis A, all the other pulleys rotate about…
