DEFINITION

Classification: 475/217

Nonplanetary transmission is disc and wheel:

(under subclass 215) Subject matter wherein one of said gears is in the form of a plate having a friction drive face, and the other said gear is generally cylindrical and has a friction drive surface on the rim thereof in contact with said face; said cylindrical gear being mounted for rotation about an axis generally perpendicular to a rotational axis of said plate, and the point of contact of said face with said rim being adjustable in a radial direction with respect to the axis of the plate to vary the speed ratio*.
