    Abstract: A machine for cutting teeth on elliptical gear blanks has a rotary work holder for blanks which is mounted on a first carriage movable in the direction of the x-axis of a twodimensional coordinate system. The first carriage is movable relative to and is mounted on a second carriage which is movable on the bed in the direction of the y-axis of the coordinate system. The cutting tool is driven to perform exclusively material removing movements. A first drive rotates the work holder at a periodically varying angular speed, and two additional drives respectively move the first and second carriages in synchronism with the angular speed of the work holder so that the pitch ellipse of a blank on the work holder travels at a constant speed along the point of contact with a pitch line of the cutting tool and that the pitch line is always tangential to the pitch ellipse at the point of contact.

    Abstract: A gear shaping machine for cutting gears with generation effected by a rotatable work holder and a tool holder carrying a cutting tool adapted to be reciprocated. The tool holder is mounted to a translatable supporting structure, the rate or speed of such translational movement during generation being selectively variable to produce variable ratio gears. Separate and independent power sources are provided for the generating train, for actuating the cutting tool, and for a servo mechanism which controls the reversing operation of the generating train. The tool holder is slidably mounted in a cradle housing for movement in a direction along its own axis (and at right angles to said translational movement) to permit production of an oversized tooth or teeth in the gear or gear sector being cut. Means are also provided to effect insertion and withdrawal of the cutting tool relative to the work for each individual cutting stroke. A counterweight mechanism is provided in operative connection to the structure for reciprocating the cutting tool to provide a smoother and faster cutting stroke.
