1. the device in the planetary gearing, wherein said device comprises:

  • Planetary pinion (14), it comprises at least three planet wheels (18), and each described planet wheel (18) has inner ring (26) and also has axle (20), and at least one bearing (36) supports described inner ring (26), and described axle (20) supports described bearing (36);

    Gear carrier (22), it is used for described planetary pinion (14), comprises first flange (24) that is connected to input shaft (46) and second flange (25) that is positioned at opposite side;

    AndEach axle (20) of described planet wheel (18) has;

    First end (19), it is gone up at first bearing length (f) and non-rotatably is coupled to described first flange (24);

    Middle section (60), it is thicker than described first end (19) that is used to support described bearing (36);

    Second end (21), it is gone up at whole second bearing length (g) and non-rotatably is coupled to described second flange (25);

    And described device also comprises;

    structure (40), and it allows the deflection in each axle (20), cooperates the engagement form of a plurality of planet wheels (18) with the Dynamic Elastic ground of the described structure of correspondence;

    It is characterized in that the described structure (40) that allows (20) deflection of described axle is as deflection (a) at interval, be formed between described first bearing length (f) and the thicker described middle section (60), and be positioned at the outside of described middle section (60) particularly.
