摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method and machining device for a face gear that can lower the cost of a high-speed and heavy-load speed change gear for a helicopter transmission and the like. SOLUTION: The machining device for a face gear wheel comprises a cutting means for feeding a milling cutter 11A with a straight or near-straight tooth shape in a radial direction of a face gear wheel 3 while adjusting the pressure angle of the face gear wheel 3 to a proper value, and a grinding means for feeding a disklike grinding wheel in a radial direction of the face gear wheel 3 while adjusting the pressure angle of the face gear wheel 3 to a proper value. The cutting and grinding work manufactures the face gear wheel 3.

摘要： PROBLEM TO BE SOLVED: To reduce cost of a speed change device of high speed and high load by executing topological cutting while adjusting so that face gear wheel pressure angle becomes a correct value, by the use of a milling cutter having tooth profile of straight line or similar to a straight line. SOLUTION: In a face gear, a straight tooth profile changing pressure angle at respective positions in the radial direction, a small bow shaped curved tooth profile, or a curved tooth profile curved inside and outside against a reference straight line is formed by topological cutting. When the straight tooth profile or the tooth profile similar to a straight line is manufactured by a face gear machining device 10, a milling cutter having the straight tooth profile or the tooth profile similar to a straight line is used, and cutting is executed so that the pressure angle of the face gear wheel becomes a correct value by adjusting the angle of a C1 axis according to the respective positions of the Z-axis.

摘要： A planetary gear reduction system has a sun gear, a plurality of planet gears, a ring gear, and a planet carrier. The planet carrier has a first plate supporting one end of planet shafts supporting the planet gears, a second plate supporting the other end of the planet shafts, and a cylindrical drum connecting the first and second plates. The first plate has first portions supporting the one end of the planet shafts; second portions connecting the first plate to the drum, the first and second portions being provided alternately in a circumferential direction; first cutouts each defined between the neighboring first and second portions, the first cutouts each extending radially inwardly from a circumferential edge thereof to a position adjacent a circle passing centers of the planet shafts; and second cutouts each defined radially inward of the second portion and between the neighboring two first portions, the second cutouts each extending radially inwardly from a first region outside the circle and a second region inside the circle.

摘要： In the present invention an output frame is connected to a portion of the outer circumference of a carrier that is closer to a front plate than a rear plate. A first region, which is an external force transmission path between the output frame and a front shaft support surface in the carrier, and a second region, which is an external force transmission path between the output frame and a rear shaft support surface, have equivalent rigidity with respect to torsional force. The front plate and the rear plate have equivalent rigidity with respect to tensile force in the radial direction acting on the front shaft support surface and the rear shaft support surface.

摘要： This apparatus includes: a sun gear having external teeth; planetary gears, each having external teeth and configured to be meshed with the sun gear; planetary shafts, each being a rotation shaft of the planetary gear; a ring gear having internal teeth and configured to be meshed with the planetary gears; and a planetary carrier including an annular base plate and an annular back plate. The planetary carrier supports the planetary shafts between the annular base plate and the annular back plate and determines a relative position between planetary gears. The annular base plate is integrally formed with one end of the planetary shaft to support the one end. The annular back plate supports the other end of the planetary shaft. At least one of the planetary shaft and the planetary carrier has lower stiffness in its part adjacent to the one end of the planetary shaft than stiffness of its part adjacent to the other end thereof.
