    The invention is primarily intended to drive the basis of a belt loom in the textile industry.
    The aim of the invention is to reduce the dynamic loads and increase the durability of the transmission by changing the tracking nature of the slave link and eliminating its slippage.
    Fig. 1 shows schematically a device for moving the basis of a loom; FIG. 2 shows a gear for converting uniform rotation into a non-uniform, longitudinal slit — FIG. 3-5 - the same, with different angular positions of the drive shaft, cross section; figure 6 is the same, top view; 7 and 8 are diagrams of angular velocities of the output shaft depending on the radius of the crank.
    The base 1 of the weaving machine (Fig. 1) is installed in the bed 2, where the frames 3 are located, which are supported and driven by pulling bodies 4. The latter are connected with the eccentrics 5 located on the shaft 6, which is the driven shaft of the transfer 7 for converting uniform rotation to uneven. Transmission 7 is driven by chain drive 8 from f oTopa 9 or another drive shaft of the weaving loom.
    Transmission 7 (FIG. 2) comprises a planetary mechanism with a drive shaft 10 located perpendicular to the driven shaft 6 and mounted in two bearings 11 and 12. A cone wheel 13 is mounted on the drive shaft 10 and interacting with the bevel wheel 14 integral with the first cheek 15 drove 16 (Fig. 6) to form the kinematic connection of the latter with the drive shaft 10. The second cheek 17 drove 16 is connected to the first by a jumper 18 on one side, made in the form of a balancing weight, and on the other by a bolt 19. The carrier 16 is installed on the driven shaft 6 on the bearing 20 and 21. In the carrier 16 on the axles 22 and 23 with cranks 24 and 25 located in opposite, set odnoventso- stems satellites 26 and 27 engaging yuschie32134-2
    with a fixed central wheel 28. The cranks 24 and 25 are mounted in bearings 29, the outer cages of which have toothed rims 30,
    5 interacting with toothed racks 31, installed through regulating interchangeable gaskets 32 on the shoulders of the driven link, made in the form of a two-armed rocker 33, rigidly mounted on the driven shaft 6.
    The planetary gear is made with cylindrical gear wheels with external teeth. It is possible to use a central wheel 28 with internal teeth, as well as other types of gear, for example, chain gears.
    Planetary gear to convert uniform rotation into
    20 uneven works as follows.
    Rotation from the drive shaft 10 is transmitted through bevel wheels 13-14 to the carrier 16, which rolls in
    25, the satellites 26 and 27 through the fixed central wheel 28. The rotation of the satellites 26 and 27 is transmitted to the cranks 24 and 25, which communicate the rocker arms 33 and the driven shaft 6 as
    3Q is the rotational rotation with the angular velocity of the carrier 16, and the relative oscillatory rotation with the angular velocity of the satellites 26 and 27, which depends on the ratio of the numbers of the teeth of the latter with the central wheel 28. The amplitude of the variable component is directly proportional to the radius R of the cranks.
    The change in the angular velocity of the output link in time is sinusoidal in character (the solid lines in Figs. 7 and 8, in the prototype are dotted), due to which the weaving machine can be operated with higher speeds, which increases productivity and reduces the load: the machine, affecting product quality and durability of the machine.

    The lack of slippage in the gear racks upon contact of the cranks with the two shoulders also leads to an increase in the durability of the gear and the machine.
