Modelling and Testing of a Toroidal CVT

This paper deals with the design and testing of a miniature CVT prototype. The CVT under study is a special toroidal-type, which is able to maintain a quasi-constant power at the output element by automatically changing the transmission ratio function of the torque applied to the output element. The power-transmitting elements of the device have been built by modifying rolling element bearings.Copyright © 2014 by ASME
