    摘要： A method for the manufacture of face or crown gears, in which a crown gear (2) adapted for meshing with a toothed pinion (3) is formed by means of a disc tool (32) having a cutting edge (38) exactly the same as the contour of the teeth of the pinion (3); the tool (32) being positioned so that its cutting edge (38) would be coincident, if the crown gear (2) were meshed with the pinion (3), with the contour of the teeth of the pinion (3) itself, and is pivoted about an axis (40) perpendicular to its own axis of rotation (35a); at the same time as the disc tool (32) is moved about the pivot axis (40), the crown gear (2) is moved translationally along a line of action (11) perpendicular to the axis of rotation (35a) of the disc tool (32) itself and is rotated about its own axis (14) perpendicular to the line of action (11); the ratio of the speeds of rotation of the crown gear (2) about its axis (14) and the speed of pivoting of the disc tool (32) about its axis (40) being variable in dependence on the position of the zone of contact of the disc (32) with the crown gear (2).

    摘要： A blade sector has a plurality of blades (5) and a circular body (6,7) connecting the ends of the blades (5) defining its own axis (8) and is finished by the working of a lateral surface (9,10) of the circular body (6,7) itself; the working of the lateral outer surface (9,10) is effected with the use of a disc tool (50,49) having a shaped cutting surface by arranging the cutting surface of the disc tool (50,49) in contact with the lateral surface (9,10) and rotating the sector (2) about an axis (25) distinct from the axis (8) of the circular body (6,7) and, at the same time as the bladed sector (2) is rotated, displacing the blade sector (2) and the disc tool (50,49) translationally relative to each other in two directions (19)(32) perpendicular to the first axis (25) in such a way that a distance (R2) between the axis (8) of the circular body (6,7) and the instantaneous point of contact of the lateral surface (9,10) with the disc tool (50,49) is kept constant during the entire working of the lateral surface (9,10) itself.
