Description

Known speed controllers of spinning machines are known, including a sliding pulley mounted on an engine shaft and controlled by a winding mechanism with the implementation of basic regulation of the main balance shaft shaft oi through a crank-lever system using a profile bar, which acts on the shifting and sliding shear mechanism.

The described controller differs from the known topics. what. in order to simplify manufacture, layer-by-layer regulation of it is carried out by it and the shaft of the winding eccentric through the shaft-connecting mechanism ;. acting on a double-spring-loaded connecting rod on the handle of the mechanism of shifting and pushing ShKiva common with the basic regulation, and the mechanism for shifting and pushing the disks of the double-sided cheek is made in the form of a washer, rotatable relative to the engine shaft and installed on the annular support; the washer carries a pair of hand-wheel rim of the steering-type, which is connected simultaneously with the layer-by-level adjustment connecting rod and the hard base control, and the crown pin of the adjustable Lenix for tensioning the belts; on the inner support CTopoiie are cracked; ki the washers passing through the holes in the ring-shaped support and interacting with oblique grooves on the cylindrical surface of the drum, which is rotatably attached to the tori of the outermost of the movable pulley disks.

FIG. 1 depicts a controller; in fig. 2-drive slat; neither FIG. 3-sliding pulley.

The controller includes a sliding pulley /,; Stap.1 on the shaft 2 e / hectoditel and transmitting their dBiZhen) e by means of special belts 3 pulley 4, fixed on the main shaft of the machine. The speed control of the machine is done by pushing ;; the sliding of the sliding discs of the 1kkiz /, as a result of which a change in the outer diameter of the grooves on the rim of the pulley for V-shaped belts occurs. Speed regulation occurs odiovreme: but

№ 129516-2vidov: base-as the removal time, and layered-as winding each layer in height. Basic regulation is implemented through the following mechanism. On the shaft 5 of the main balancer arm, a lever 6 is fixed, hingedly connected to the pull 7, which is connected to the profile bar 8, which acts through the pull 9 on the handle 10 of the sliding and sliding mechanism of the sliding sliding plates. As the time of removal is, the ha 7 moves and moves the profile bar 8 in one direction only. As the profile bar 8 moves, the latter rotates the handle 10 of the mechanism for sliding and pushing the disks of the sliding bar 1 through pu 9.

This same handle 10 is also affected by a layer-by-layer adjustment mechanism, which is made as follows: a curved shaft 12 with a pinch 13 is fixed to the shaft / winding eccentric; A shatun 14 is connected to the latter, another circuit of which passes through the grip 15 of the handle 10 and on both sides of the grip is equipped with springs 16. These springs prevent the mechanism from breaking and are involved in the basic setting. As the winding diameter changes in each layer, the sha-tun 14 moves to one side or the other and turns the handle 10.

The mechanism for expanding and sliding the disks of the sliding chuck Structurally designed as follows: fixed disks 18 are fixed on the hub 17, fixed with a key on the shaft 2 of the electric motor, between them (also on the hub 17} moving disks 19 moving in axial direction. These disks interconnected by means of bolts 20 spacer sleeves 21. The movable disks 19 are rotatably attached through the rightmost disc 19 to the drum 22, which has oblique grooves 23 on the cylindrical surface 23. A cracker interacts with these grooves 24, placed on the inner side of the support 25, mounted on the support rotatable relative to the motor shaft, the grump 26. The edge of the grip 25 protects the grip 26 from its longitudinal displacement. p layer-by-layer adjustment. A bracket 27 is also fixed on the washer 26, on which an adjustable axle 28 is mounted for tensioning the V-shaped belts 3.

During the operation of the machine, the haul 9 and the rod 14 deflect the handle 10 in that direction / fug side, respectively, turning the jaw 26. When the last sucker 24 is rotated, slide the oblique groove 23 of the drum 22, moving it in the axial direction. Together with the drum, the movable disks 19 are displaced to the right or left, moving away or approaching the fixed disks 18. At the same time, the outer diameter of the kiavok between the disks changes. When the washer 26 is rotated, the bracket 27 is rotated appropriately with the Lenix 28, which ensures the constant tension of the belts 3.
