SU13560A1 - Friction transmission to watering machines - Google Patents

Description

Practice shows that at the beginning of the winding of the coil of the watering machine, the spindle speed should be slower so that the thread would not break, but as the winding of the coil turns, the speed of the spindle can be increased and reaches the highest value at the end of the coil winding. During the spinning of jute, silver and flax, the coil is produced in cylindrical layers. The proposed drying device, which automatically changes the speed of the spindle, as well as all the organs of the winding machine, depending on the winding of the coil in cylindrical layers, looks like. This change in speed occurs automatically depending on the L yarn, and furthermore in the proposed device there is a device, it is possible to set the initial winding speed and final speed within certain limits and it is possible to change the speed during the spin process by simply turning the handwheel.

In FIG. 1 shows a diagram of the proposed friction gear, FIG. 2, a diagram of a controlled adaptation of the spindle speeds and FIG. 3 is a side view of a device mounted on a water machine.

To dry out the above change in the speeds of the spindles, a friction gear is introduced into the drive of the watering machine (Fig. 1, 2 and 3), and the shaft 1

with cone-shaped drums 2 interlocking with the disks 3 of the second shaft 3. Shaft 1 is driven into rotation from the factory drive or from the shaft of the water machine by a belt drive onto the pulley 4 (Fig. 3). The shaft rests on ball bearings 5 and may have axial movement. The disk drum 3 is also resting on ball bearings that can move in a direction perpendicular to the axis of the disk drum and are located by pressing two shoulders 7 with the counterweight 8. The pressure of these disks drives the disks to the surfaces of the cone-shaped shaft 1 drums. Shaft 1 by means of a pin sleeve 9 is connected with a two-arm lever 10 rotating on an axis 38 and carrying a handwheel 11 with a screw 12 coupled to a sleeve 13 associated with a sector 14 rotating about Axis 38. When the sector 14 rotates, it rotates about an axis 38 and the lever 1 0, and at the same time, the shaft 1 with the cone-shaped drums, which is connected along its axis with the lever 10, moves along its axis.

The toothed sector 14 is coupled with a worm 15, shaft 15 of which is connected by Hooke’s hinge 16 to shaft 17, on which a ratchet wheel 18 is mounted. At the end of shaft 17, a loosely three-shouldered lever 19 with two dogs 20 is fitted (Fig. 1 and 2). The lever 19 is connected by the screws 21 and 24 with a screw drive of the handwheel 22. Th ha 21 pesetas rollers 23, covering the curvilinear beam 24, TsoTOj bifl by means of the hook 25 sa. is engaged with the lever 26, irnvodi.my in the oscillatory movement from the axis of the winding eccentric through the belt strap. With one turn of the winding eccentric, two cylindrical layers of yarn are wound onto a reel. Ustag is poured by means of a handwheel, 22 with a thrust of 24 tons of guards 21 to any position within the limits of O to the largest value, we will receive the corresponding turn of the worm and sector, and hence the movement of the shaft 1, t, -e. new spindle speed depending on the movement of the annular plate of the water machine.

Since the layer of yarn reeling on the coil has a different thickness depending on Lt: L yarn, then the required movement of the shaft 1 depending on L yarn. In practice, it is possible to define and mark on the curved bar 24 divisions corresponding to the numbers of pr zhp, on. which are set to 21 for obtaining speed limits that satisfy the best working conditions.,

The described device makes it possible to install the lowest and highest spindle speeds for a given grade of material. To set a lower speed, using the handwheel 11, set the discs to the small radius of the cone-shaped bar. Fig. 3 shows the handwheel 11, equipped with the corresponding divisions, according to which a view is made by the type of yarn, the lower limit of the initial speed of the spindle. The handwheel 27 serves to set the highest speed limit. For this, an electrical method is applied, which consists in that the handwheel 27 is connected to the screw shaft 28, screwed into the bracket 28. The screw at the end carries an actuating ring 29 intended to close the current, for which the support sleeve 30 has a bracket 31 carrying two moving together with the shaft of the contact, connected by wires with the electromagnet 32. When the shaft 1 moves, the contacts are connected by the contact 29 and the current, the electromagnet passes, draws in the core, closed with the shaft supporting part 15, as a result the shaft is bent and locked rum ZZU sector W thus freed from engagement with the worm 15, under the influence of the spring 34 returns Niemi

drum 2 to its original position. With the handwheel 11 it is possible to change the speed during the spinning process - by decreasing or increasing depending on the working conditions. When the shaft 1 is moved to its initial position, the sleeve 9 moves the thru 35, at the end of which there is a movable stop 35, which presses the crank lever 36, and through the leverage system pulls the piston 33, thanks to the axis 15 attracted by the spring 37 and the worm to 15 interlocks with sector 14 again.
