ABSTRACT:
A method for the manufacture of gears, in which a gear adapted for meshing with a toothed pinion is formed by means of a disc tool having a cutting edge exactly the same as the contour of the teeth of the pinion; the tool being positioned so that its cutting edge would be coincident, if the gear were meshed with the pinion, with the contour of the teeth of the pinion itself, and is pivoted about an axis perpendicular to its own axis of rotating; about the pivot axis, the gear is moved translationally along a line of action perpendicular to the axis of rotation of the disc tool itself and is rotated about its own axis perpendicular to the line of action; the ratio of the speeds of rotation of the gear about its axis and the speed of pivoting of the disc tool about is axis being variable in dependence on the position of the zone of contact of the disc with the gear.
