VARIABLE-SPEED V-BELT DRIVE MECHANISM

Two identical conical disks 1 form an adjustable sheave that rotates about fixed axis A-A and whose side members (disks) 1 can be brought closer together or spread farther apart along axis A-A. Similar conical disks 2 rotate about and slide along fixed axis B-B. Flexible link 3, in the form of a wide V-belt, flexible but rigid to some extent laterally, runs over the sheaves with movable side disks…
