Patent ID: 7887451

Claim:
Infinitely variable transmission ( 1 ; 1 ′) comprising a) a support body ( 2 ; 2 ′); b) a plurality of peripheral gears ( 15 ) rotatably mounted on a selected one of said support body ( 2 ; 2 ′) and mounting elements mechanically coupled to said support body ( 2 ; 2 ′) in such a way that rotating shafts ( 12 ) thereof are oriented parallel to each other, with distances between the rotating shafts ( 12 ) of said peripheral gears ( 15 ) being adjustable ( 20 ) so as to always be located on an outer surface of a hypothetical cylinder; c) at least one row of tooth-engaging elements surrounding said peripheral gears ( 15 ) on the outside, with which at least several of said peripheral gears ( 15 ) engages; d) a rotational body ( 3 ; 3 ′), substantially coaxial to an axis of rotation of the hypothetical cylinder, and whose rotary movement is coupled to the rotary movement of said peripheral gears ( 15 ); e) wherein the rotational coupling between said peripheral gears ( 15 ) and said rotational body ( 3 ; 3 ′) is effected by means of at least one compensating transmission to provide an asynchronous rotation of said peripheral gears ( 15 ), whereby said peripheral gears ( 15 ) are rotatable at different speeds when a distance between said gears ( 15 ) changes during synchronous adjustment of a radial distance of the rotating shafts ( 12 ) to a central axis of rotation of said rotational body ( 3 ; 3 ′), while several of said peripheral gears ( 15 ) contribute to power transmission.
