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.

Gear-roller

A gear finishing machine having a rotary work gear support and a rotary honing tool support and a pivot mounting for one of the supports whose pivot axis extends parallel to the rotation axis of the rotary support mounted thereon, the pivot axis being located substantially within the angle between the lines of action of a meshing gear and gear-like hone carried by the supports. In a preferred embodiment the construction is provided in a pivoted tool support head provided with means for fixing the head against pivotal movement for use in gear shaving, or releasing it for limited pivoting movement for use in gear honing.
