<p>A roller and bearing assembly for a rolling-traction continuously variable transmission unit wherein the roller (102) has an outer periphery for running on a pair of transmission races to transmit drive from one to the other and comprises a hoop for bearing compressional force applied to the roller by the transmission races, the bearing comprising a rotary bearing (204) disposed within the roller hoop and having inner and outer bearing races, a coupling (206) between the roller hoop and the bearing serving to rotatably mount the roller upon the bearing and to accommodate deformation of the roller hoop due to the compressional force without corresponding deformation of the outer bearing race. <IMAGE></p> |
