F16H15/10 - CPC Classification

Gearings for conveying rotary motion with variable gear ratio, or for reversing rotary motion, by friction between rotary members without members having orbital motion; Gearings providing a continuous range of gear ratios in which a member A of uniform effective diameter mounted on a shaft may co-operate with different parts of a member B in which the member B is a disc with a flat or approximately flat friction surface in which the axes of the two members cross or intersect

• F16H15/12 » in which one or each member is duplicated, e.g. for obtaining better transmission, for lessening the reaction forces on the bearings 6
