ABSTRACT:
A planetary system suitable for amplification of horse power by a single or multi-stage arrangement from a rotary power source. In a stage provided are three axially concentric elements, whose axes define the system axis, a braked reaction gear and two non gear elements that rotate at the same angular speed, the input carrier and the output lever. Driven by and on the carrier is an iso-planet whose gear element meshes with the reaction gear and whose non-gear element, a free floating rim isolated from the rotation of the gear around its center and carried around the system axis is adapted to mate with and drive the output lever in specifically selected position on the system radius that is radially perpendicular to a point of large tangential force of the torque on the momentary driven radius of the iso-planet gear element. Output lever driven by a large force renders a larger torque and therefore power than the power applied. Also, the iso-planet with the output lever are applicable in today's designs of inverted and non-inverted planetary systems that have, input into a sun gear or ring gear and the output is the carrier. Idling the carrier and utilizing the output lever mated with an iso-planet of original size gear element will render, an angular output speed of the predetermined reduction ratio and an output torque larger than predetermined by the reduction ratio, therefore an input to output power ratio, larger than one to one.
