    The planetary gear system includes two parallel operating planet gears interposed between an input and an output shaft, with a common planet gear carrier secured to the output shaft and two telescoped intermediate shafts for the sun gears. These intermediate shafts are resiliently mounted for radial balance while a particular gear coupling between the input shaft and the two intermediate shafts ensures torsional balance between the two branches. This branch coupling, providing torsional balance, is described in considerable detail.

    (54) PLANETARY TRANSMISSION
    The invention relates to mechanical engineering and can be used in heavy duty responsible gears.
    A planetary gear is known, combining twin-helical helical gears with opposite tilt of the teeth, forming two parallel planetary rows, a floating sun gear. The load distribution over the planetary wheels within one row is achieved by the radial displacement of the sun gear rims, and between the planetary rows by its axial displacement Lll. transmission ability. The equalizing effect of the suspension is provided only with helical gears.
    Closest to the proposed technical entity is a planetary gear, comprising a housing, input, output and intermediate shafts, split gear
    wheels that form parallel planetary rows with an odiuuM carrier, the sun wheels of which are mounted on intermediate shafts, one of which is located inside the other, and a device for leveling the load in parallel rows. All gears are helical. The solar wheels are connected to each other.
    10 with the help of couplings with helical gear f 2.
    The presence of friction forces decreases the reliability of load leveling between parallel rows.

    The purpose of the invention is to increase the reliability of the transmission.
    The goal is achieved by the fact that in a planetary gear comprising a housing, an inlet, an outlet and an intermediate shaft, there are split gear wheels that form parallel planetary rows with a common carrier, whose sun wheels are mounted on intermediate shafts,
    25 of which is located inside the other, and a device for leveling the load in parallel rows, the latter is made of a P-type mutually acting with the input shaft of the sleeve
    and three axes installed in the last parsley input shaft and arranged in pairs, evenly around the circumference of three pairs, connecting gear wheels placed on axes displaced axially one relative to the other and engaging in pairs between the assembly, forming two parallel rows, and two gears located at the ends of the intermediate shafts and engaged with the connecting wheels of the corresponding parallel row, and the outer intermediate shaft is mounted on the inner shaft and the latter is in the carrier and hub ke on elastic bearings, and the sleeve is mounted on two rolling bearings, respectively, in the housing and in the carrier.
    FIG. 1 shows the proposed planetary gear; in FIG. 2, section A-A in FIG. one.
    The planetary gear train comprises a housing 1, an input (not shown), an output 2, and two intermediate shafts: an outer 3 and an inner 4. At the ends of the latter are located the sun gears 5 and 6, meshing with the split gears 7 and 8, forming two parallel planetary gears. Yes. The planetary wheels 7 and 8 are mounted on axles 9 in a common carrier 10, integral with the output shaft 2, and interacting with the central wheels 11 and 12 with internal teeth fixed in housing 1. To limit the bending deformation of axes 9 in the driver 10 An intermediate support 13 is provided. The driver 10 is installed in the housing 1 on the supports 14 and 15.
    The device for leveling the load between the planetary rows contains a sleeve 16 mounted on the splines on the input shaft, made in the form of two cheeks 17 and 18, connected by jumpers 19 (Fig. 2) In the sleeve 16 parallel to the input and output shafts are three axes 20, on which three pairs of connecting gears 21 and 22 are placed, displaced one relative to another in the axial direction and engaging in pairs with each other.
    At the ends of the intermediate shafts 3 and 4 there are gears 23 and 24 which engage, respectively, with connecting gears 21 and 22. The hub 16 is mounted on rolling bearings 25 and 26 housed respectively in housing 1 and driver 10. The outer intermediate shaft 3 is mounted on the inner shaft 4, and the last - in the carrier 10 and the sleeve 16 on the elastic bearings 27,28,29 and 30, respectively.
    The transmission works with;: in a single way.
    The rotation from the input shaft is transmitted to the sleeve 16 and then through the connecting gears 21 and 22 to the intermediate shafts 3 and 4 and the sun gears 5 and 6, through the fixed central wheels 11 and 12, the carrier 10 and the output shaft 2.
    The load leveling on the planetar wheels inside X1 of each planetary row is achieved by the radial displacement of the sun gears 5 and 6, and the load leveling between the planetary rows is ensured by the pinching of the gear wheels 23-24.22-24, which can be balanced only if the forces in the gears are equal. Thus, the proposed planetary gear has a reliable device for leveling the load on the planetary wheels in the circumferential and axial directions with spur gears.
