HAIN LEVER-TYPE MECHANISM WITH A FLEXIBLE LINK AND PERIODIC DWELLS OF THE DRIVEN LINKS

Abstract

Pulleys 1 and 6 are of equal diameter. Pulley 1 rotates about fixed axis A and, through flexible link 7, rotates pulley 6 about fixed axis B. Links 2, 4 and 5 are connected by turning pairs C, D and E to flexible link 7. Link 3 is connected by turning pair G to link 2 and by turning pairs F to links 4 and 5. When pulley 1 rotates about axis A, and points C, D and E are all travelling along a straight portion of their path, links 2, 3, 4 and 5 have dwells with respect to flexible link 7. When any of the points D or E passes over to a circular portion of its path, links 2, 3, 4 and 5 turn with respect to flexible link 7. When only point C passes over to a circular portion of its path, only links 2 and 3 turn with respect to link 7. $1926$FL,D$
