ABSTRACT
Two possible modes of torque transfer appear possible. In one there may be momentary no-slip contact between the driving and driven discs at some point at or between radii Rw/2 and R+w/2, where w is the width of the tire on the driven disc. Since the location of this point may change from moment to moment, the driven angular velocity may vary between
(2-2)
Consequently, the tire may slide over the driver disc except at some point along a line in the contact region. In the other possible mode there may be slip everywhere over the contact region. In the first case, the rotational speed of the driven disc may be found from equation (2-1), and in the second case it will not exceed that given by equation (2-1).
