Patent ID: 7192375

Claim:
A torque varying device, comprising: an input component, where said input component has an aperture configured to allow insertion of a central member therethrough; a lobe member, said lobe member being attached to said input component, said lobe member being axially aligned with said input component but centrally offset from said input component; a driver disc, said driver disc being engaged with said input component through said lobe member via a rolling mechanism, wherein said driver disc is centrally, axially aligned about said lobe member, where said driver disc moves about said input component in eccentric fashion, responding to rotational force of said input component via said lobe member and said rolling mechanism; and an engagement means, wherein said engagement means is located along the periphery of said driver disc and alternatingly engages an output component as said driver disc eccentrically moves about said input member, said output component being configured to alternately receive said engagement means, and to rotate about said driver disc and said input component.
