Abstract

Rotational CVTs (continuously variable transmissions) constrain the velocities of two rotational joints to a computer-controlled ratio. CVTs are traction drive mechanisms that rely on the support of traction forces across rolling contacts. When called upon to transmit loads, CVTs produce a velocity ratio that departs from the ideal transmission ratio. This paper reports on the results of our analysis in pursuit of understanding the mechanics of the rotational CVT. We present the measured velocity ratios in the face of lateral loads at various transmission settings. In addition, we present our model that closely fits the empirical data.
