Abstract
A gear rolling machine in which a work gear and a conjugate gear-like rolling die are rotated in tight mesh with relative radial pressure of metal deforming intensity applied between the rotating members. The radial feed which applies the pressure is applied by a power train which includes a worm-worm gear combination driving a screw shaft-nut combination. After maximum pressure has been applied, the center distance is reduced by limited predetermined axial movement of the worm, without rotation, in which the worm acts as a rack to provide a predetermined limited rotation of the worm gear, and hence of the screw-nut combination.
