    A transmission for the shedding mechanism (dobby) of a loom in order to produce a non-uniform drive from a uniform drive, having a drive shaft and a driven shaft aligned therewith, said shafts being mounted in a transmission housing. In order to simplify the construction, a rotor is arranged fixed for rotation on the drive shaft, the rotor bearing at least one gear segment which is swingably supported on an eccentric shaft and has two cam rollers arranged in different planes, the gear segment being in engagement with a driven pinion arranged fixed for rotation on the driven shaft and the cam rollers cooperating in force-actuated and/or form-locked manner with two cams fastened in different planes to the transmission housing, the asymmetry of which cams producing a relative movement per revolution between the drive shaft and the driven shaft. The relative movement per revolution can be adjusted by replacing the two cams. The rotor can also be formed with two arms and carry two gear segments, the cam rollers of which cooperate with the two cams.

    (54) MECHANISM OF DRIVE REMAINS TO THE MOBILE MILL
    one
    The invention relates to textile machinery and can be used in shedding mechanisms. max
    The known mechanism of the drive remiz K5
    to the loom, which is a drive shaft, located in the housing and connected to the machine drive, connected to the driven shaft by means of a gear transmission, the leading gear element of which is connected to the carrier mounted on the drive shaft, and the driven element to the driven shaft shaft, kinematically associated with the shafts and placed coaxially with the drive shaft G1 15
    A disadvantage of the known mechanism is the complexity of the design and the presence of a large number of parts subject to abrasion.
    Purpose of the invention - increase by -20
    The reliability of the mechanism of the drive shaft to the loom.
    The goal is achieved by the fact that the drive mechanism of the shaft to the loom, containing the located B25
    the casing and a drive shaft connected to the machine drive, connected to the driven shaft by means of a gear drive, the leading gear element of which is connected to a carrier mounted on the drive shaft, and the driven gear element with a driven shaft, kinematically connected with shafts and placed coaxially at the drive shaft, has a pair of cam mechanisms, the cams of which are out of phase by 18 ° and fixed on the housing coaxially with the driven shaft, and the rollers interacting with the power and / or geometric closure with the cams are mounted on the driving element Not all gears, while the driven, gearing element is rigidly connected to the driven shaft, and the driving element is embodied as a toothed sector and mounted on the carrier by means of an eccentric axis, while the carrier has two leading arms, and the gear has two leading gear sectors, each of which is mounted on one of the carrier shoulders.
    FIG. 1 - mechanism, common EID; on 4ig. 2 - incision for PVC. 3; on 4ig. 3 shows a section BB in FIG. 2; on fng. 4 is a diagram of the angular velocities of the driving and driving shaft} in FIG. 5 the same, shafts with one turn nh.
    On the bed 1 of the weaving machine, remix 2 is displaceable in the vertical plane with hock bodies 3 by means of cranks 4, the number of which corresponds to the number of shafts arranged with an eccentric disk 5. The cranks 4 located one near the other, with their eccentric disks 5, are driven the action of coupling and disengagement with the driven shaft 6 by means of radial displacement of wedges located on the eccentric disks 5, while the clutch disengagement occurs according to the results of feeling nor (not shown) sample cards. The drive shaft 8 is driven by a chain drive 9 connected to a 10 weaver drive about the machine.
    The driven shaft 6 and the drive shaft 8 are arranged in series in the gearbox 11. At one end of the drive shaft 8, the carrier 12 is rigidly fixed with screws 13. The drive mechanism of the shaft has a pair of cam mechanisms, the cams 19 and 20 of which are out of phase by 18 ° and fixed on the body coaxially to the driven shaft 6, and the rollers 16 and 17, interacting with force and / or geometrical closure with the cams 19 and 2O, are mounted on the gear drive 18 and the gear drive 18 is rigidly connected with the drive shaft 15 out flax in the form of a toothed sector and mounted on a carrier 12 through an eccentric axis 14, while the carrier 12 is made two shoulders, and the gear transmission has two leading gear sectors 15, each of which 1X is installed on one of the carrier arms 12.
    Due to the asymmetry of both cams 19 and 20, at each revolution, a relative movement is created between the driven 6 and the drive shaft, the motion characteristics of which is shown in the diagrams (Figs. 4 and 5). At the same angular velocity of the drive shaft 8 (FIG. 4), a slowdown occurs. The development of the angular velocity WQ of the driven shaft 6 with one revolution from O to 90 ° and then the angular velocity again increases from “.9O to 180 °. As can be seen from the diagram (Fig. 5), it is possible to make the angular velocity Cp of the driven shaft 6 as compared to the angular velocity W of the drive shaft .8 when 9О
    negative, i.e. In a certain place, for example, in the clutch zone of the wedge 7, the shaft 6 can first be passed past the engagement point, then returned and passed by again, so that the wedge 7
    to provide the possibility of reliable coupling or uncoupling.
