| 摘要 |
The present invention is directed toward an apparatus for continuous speed variation of an output member with respect to a primary input member. In particular, the present invention provides a device having an output that rotates at reduced speed and increased torque relative to its prime input through the low friction, rolling engagement of its members, or alternatively, at increased speed and reduced torque for overdrive applications. Furthermore, the speed of the output member may be varied continuously and infinitely between the apparatus's lowest and highest ratio via a secondary input member and its low friction, rolling engagement with the device's members.
