    • 专利摘要:
    A rotation shaft machine with a wedge coupling between a drive shaft and an eccentric device for the shaft movement, with which the wedge is mounted in a radially extending recess of an eccentric disc and in two coupling positions which lie diametrically opposite to one another according to a pattern is couplable in and decouplable from an axially extending groove of the drive shaft. The wedge has a groove which is open in the axial direction and at each coupling position there is arranged a switching rod, which is controllable according to the pattern, with a coupling member, the coupling member crossing into the groove of the wedge.

    S and the inner joint is articulated; it contacts the end with the lateral plane of the wedge and has two radial grooves for alternately placing the wedge in the position of its disengagement and the spring of the wedge. In addition, each hake of incorporation has a longitudinal directional groove, and at the end of the stationary ring there is a protrusion placed in this groove. FIG. 1 shows a diagram of the drive of the shank in the lower throat position; in fig. 2 - the same, in the position of the upper pharynx; in fig. 3 - wedge connection, side view; in fig. 4 shows section A-A in FIG. 3; in fig. 5-8 are control diagrams of a kLin coupling for moving the shafts from the lower pharynx to the upper one and for fixing the shafts in the position of the lower and upper pharynx; in fig. 9 is an embodiment of a clutch connection. Remizki 1 2 are connected with a spike 3 curve, installed on an eccentric disk 4. Wedge 5 serves to connect the sliding disc 4 with the leading shaft 6, which has two diametrically opposite groove 7. Wedge 5 has an axially open groove 8 for placement connecting element 9. The connecting elements 9 are fastened at the ends of two coo diametrically opposed rods 1O and 11. The groove 8 has overlapping sloping surfaces 12, and at the end of the connecting element 9 there are curvilinear surfaces 13. On the side opposite to the groove 8, Each SLING has a nozzle 14 placed in the radial groove 15 of the eccentric disk 4. A spring 17 is installed in the deep hole 16 of the nozzle 14. A ring 18 is placed concentrically with the lead head 6, which has two axial slits 19 in the area of the switching rods 10 and 11 in which the outer end of the wedge 5 enters. The guide ring 20, the circumferential ring 18, is fastened behind the fastener. The latch 21 serves to fix the ring 18 in its normal working position. The pins 22 are fixed on the guide ring 20, and the enclosing 1O and 11 have oval holes 23 in which the pins 22 of the guide rings are located. The inclusive barbells 10 and 11 are located through iapf 24, located at the free ends of the rods, connected to the control levers 25 and 26, e4 are interconnected by a connecting rod 27 and axes 28 and 29. On the axis 28 of the control rod 25, the rocker arm is mounted 30, on which two pressure rods 31 are pivotally fastened. The pressure rods 31 are connected with u-terminals 32, which are in contact with a paper map (not shown) that is moved by a chlinder 33. The pressure strips 34 are mounted in such a way that when the probes -32 enter the holes of the paper map, the push rods 31 are displaced to the trajectory of the pressure strips 34. The control lever 25 has an oval opening 35 on the control axis 36, which is capable of reciprocating. Control lever 26 is mounted on an off-axis axis 37. Control arms 25 and 26 have springs 38 for returning them to their original position. The fixedly mounted stops 39 serve to interact with the rocker 30. In order to compensate for production tolerances and prevent jamming in the control, the lever 25 is mounted on the axis 28 by means of an elongated hole 4O. FIG. 9 shows a variant of the wedge coupling, in which the ring 18 and the stationary guide ring 20 are missing. The outer ends of the open wedge 5 can enter the recess 41 of the fixed and spring-loaded locking lever 42. Otherwise, the WATER and control remain unaltered. meny. The carriage works as follows. When the position of the lower throat (Fig. 5), the probes 32 fall into the holes in the paper map. At that, the push rods 31 raise the rocker ZO from the stop 39 and shift the axis 28 by the value Y The hinge 24 of the including rod 1O does not communicate with movement since the control axis 36 is simultaneously shifted by the amount X by means of the pressure bars 34. When the upper shed is in position (Fig. 6), the wedge 5 finds the connecting element 9 including rod 1D and exits the groove 7 in the driving shaft 6.
    When the upper shed is in position (Fig. 7), the ups 32 do not fall into the hole of the paper card, so that the push rods 31 are not suitable for the trajectory of the push bars 34 and therefore are not pressed. The yoke 30 is adjacent to its support 39 so that the axis 28 is also not shifted. Since the control shaft 36 of the control lever 25 at fixed planar 28 is displaced by X, the trunnion 24 of the descending rod 10 moves respectively by the Z value and the wedge 5 again enters the groove 7 of the drive shaft 6, At half a turn of the eccentric disk 4, the heddle moves from the position shown in FIG. 7 to the position shown in FIG. 8. Remits 1 in this position remains in the lower os position.
    Tdim way, the use of the proposed device provides a reliable direction and orientation of the wedge at a high frequency of rotation of the drive shaft of the machine.

    1. A rotary helix carriage of a weaving machine containing drive blocks according to the number of remises, each of which includes an eccentric mounted with the possibility of engagement and disengagement with the drive shaft in two diametrically opposite positions by means of a spring wedge mounted in the radial groove of the eccentric and having an open the axial direction of the groove to accommodate the locking rod of the switch-on, which is connected to the software mechanism, and controls the helix flap, rigidly fixed, on the screen The centerpiece is perfect because each drive unit has two rings installed coaxially on the drive shaft between the eccentric and the T51 of the drive, in which the outer ring is rigidly fixed on the frame, and the inner ring is mounted The end with the side plane of the wedge and has two radal groove grooves for alternately placing the collar in the position of its disengagement if spring loaded limits the rotation circuit.
