  • Patent number: 4043021
    Abstract: A planet carrier for an epicyclic gear train comprises two parallel sheet-metal disks of different diameters with coaxial central apertures for the insertion of a sun gear. The larger disk is formed with peripheral teeth and with a plurality of arcuate slots as well as several mounting holes between its periphery and its central aperture. The smaller disk has mounting holes aligned with those of the larger disk and is integral with a plurality of spider legs whose extremities are received in the arcuate slots of that larger disk and are welded thereto. The aligned mounting holes, each pair of which is designed to receive the shaft of a respective planet pinion, are each provided with two diametrically opposite notches into which the corresponding shaft end is tamped to wedge the shaft firmly in position. The notches are formed by punching, concurrently with the stamping of the respective disk from a sheet-metal blank.
