Description

A known mechanism for arranging the yarn in a circle of a centrifugal spinning machine includes a yoke rod and a connecting shaft connected to the rod by means of a crank, rotating at a variable angular velocity and softening the impact actions of those parts of the mechanism that wear out at the turn of the rod.

A disadvantage of the known mechanism is that it does not provide an increase in the number of handles moves above 52-55 and prevents an increase in the spinning speed.

The proposed mechanism, in comparison with the known one, eliminates the noted disadvantage, allows to increase the thread spinning speed and to relieve the impact action when changing the stroke of the rod with yarn feeders. It differs from the well-known in that, with a common goal, the addition and subtraction of velocities are carried out in it by means of a differential mechanism receiving rotation from the main shaft.

For these purposes, the shtanga is equipped with a rectangular frame that carries a free-moving cracker, enveloping a disk, eccentrically attached to a rotating shaft with variable speed, on which a pair of gears of equal number of gear teeth rotates in different directions, one of which is set in motion from the main the shaft of the machine through the parasitic chester} 1yu and has a figured groove for the finger, mounted on a Krivoschipnom roller.

The crank roller is mounted on another gear, rotated directly by the main shaft of the machine, and has at the other end a toothed sector that interacts with a gear wheel mounted on the shaft.

FIG. Figure 1 shows schematically the layout mechanism; in fig. 2 - disk layout; in fig. 3 - a disk in / 1 diametral section.

No. 141254- 2 Disc /, folding thread, eccentrically set on rotating shaft 2 with variable speed and located in free-moving rectangular frame 3 cracker 4. Frame .9 is connected through bar 5 to the thread carrier 7 (made, for example , in the form of funnels). On shaft 2, gears 8 and 9 equal in number of teeth are mounted, rotating in different directions. Movement shaft. is transmitted from the main shaft 10 of the machine via a gear //, mounted with gear 6, which is freely seated on the shaft 2.

In the hole of gear 8, the rotating roller / 1 rotates freely. On the crankshaft 13, roller Palen 14 is mounted, moving along the figure groove 15 of gear 9, which sits freely on shaft 2 and receives rotation from the main shaft 10 through parasitic gear 16. At the end of the crank roller 12 it is fixed a gear sector 17 interacting with a gear wheel 18 fixed on the shaft 2. The gear wheel 18 has a total speed W folding of a constant CKOpociH W gear 8 and a variable speed W depending on the profile of the groove 15 of the gear 9. For one turn from gear 8, speed 2 changes its value twice. To change the span of the yarn feeder, its eccentricity value is changed by shifting the disk / relative to the shaft. The disk is fixed to the bracket 19 with bolts 20.

The total variable speed in accordance with the work of an eccentrically set disk / ensures the constant linear velocity of the pickup.

Subject invention

A mechanism for arranging the yarn in a circle of a centrifugal spinning machine, including a rod with yarn feeders, characterized in that, in order to increase the speed of the spinning and reduce the impact action when changing the stroke of the rod, the latter is provided with a rectangular frame, a free-moving crush, covering a disk fixed eccentrically on a shaft rotating at variable speed, carrying a pair of gear teeth of equal number in gear that turn in different directions, one of which is driven from the main shaft through parasitic th gear and has a shaped recess for the finger on the crank fortified roller mounted on the other gear, directly rotatable main shaft of the machine, while on the other end of the crank roller mounted sector gear, vzaimodeystvuyushy with the gear wheel fixed to the shaft.
