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

摘要： 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.

摘要： A gear-drive assembly between an input shaft (17, 117) and an output shaft (10, 110) comprises a ring gear (12, 112) having a peripheral portion provided with corresponding and opposite toothings (14, 15, 114, 115) on the two faces thereof. Meshing with each toothing (14, 15, 114, 115) is a pinion of a pair of pinions (16, 25, 116, 125) carried by parallel shafts (17, 22, 117, 122) interconnected with each other by a driving gear (20, 21, 120, 121) to rotate at the same speed and in opposite ways. One of said parallel shafts is the power-input shaft (17, 117). The ring gear (12, 112) is carried by the output shaft (10, 110) in a floating manner to vary the distance of its toothings (14, 15, 114, 115) from the axis of the pinions (16, 25, 116, 125).
