ABSTRACT:
A variable speed transmission of the friction-drive type comprises a driving shaft; at least two ball-driving elements; the driving shaft having drive means associated therewith for rotation of the ball-driving elements; first torque-transmitting means connected with the driving shaft and associated with the ball-driving elements for rotating the latter in unison with the drive shaft; first ball means comprising first cage means and at least two balls each of which balls is in rolling contact with the ball-driving elements; driven-shaft means comprising at least three driven shafts disposed parallel to one another; second ball means comprising second cage means and at least two balls each of which balls is in rolling contact with two of the three driven shafts; the gap between two adjacent ones of the three driven shafts being smaller than the diameter of the respective ball being in contact with these two adjacent driven shafts.
