Abstract

The invention is a gear-to-gear linkage that relates to many variable continuous-load-support applications such as robotics, tools and machinery, but most significantly it relates to infinitely and continuously variable transmissions (CVTs). The basic element of the linkage is a unidirectional multi-ratio differential mechanism whereby input power is passed directly to a load and the rotational position and speed of the output is independently controlled to meet operational requirements. Most notable of this invention is its simplicty and its capacity to be scaled from the very small to the extremely large to accommodate any practical load for which gears can be built.
