Description

"

The invention relates to the textile industry and concerns exhaust devices-tape machines.

The purpose of the invention is to increase reliability.

FIG. Figure 1 shows one of several stretched pairs. exhaust device, front view with n |) odolny incision of the pressure roller; in fig. 2 - the same, top view; neither FIG. 3 shows a bearing housing of a roller, longitudinal section; FIG. 4 - the same, side view; in fig. 5 is an extreme saddle, longitudinal section; FIG. 6 - the same, top view; in fig. 7 — medium saddle, longitudinal section; in fig. 8 - the same, top view; in fig. 9 is a structural diagram of a pressure roller.

Each exhauster pair of the device consists of a drive corrugated cylinder 1 and a pressure roller 2 installed on it with an elastic coating 3 by means of rolling bearings 5 placed at the ends in the housings 4 and the bearings are spaced by sleeves 6 and closed with lip seals 7 .

The end parts 8 of the bodies are cylindrical and freely placed in through 2 slots 9, which are fixed through the roller side, fixedly mounted saddles 10 and 11 of the exhaust device with the formation of a gap A between the end face 12 of each body 4 and the surface facing 13 s;

The pressure rollers are pressed to the cylinders by load mechanisms (not shown) connected to the bearing housings 4 by means of cylindrical rods supported by springs (not shown) supported by springs.

On the facing one another - the inner surfaces of each saddle inside the groove 9, the projections 14 along the triangular side are made along it. cross section shape. The diameter of the cylindrical parts of the 8 bodies corresponds to the distance B between the projections 14 of the saddles.

The exhaust device works as follows.

A product sandwiched between rollers and cylinders of fibers is due to an increase in the frequency of rotation of the cylinders and

5 — along with them, the pressure rollers are subjected to stretching and thinning.

The design of the pressure roller assembly of each pair of exhaust devices has

10 six degrees of mobility j W-6

(Fig. 9). The roller 2 itself has four degrees of mobility together with 4 bearing housings: translational movement along the x and z axes and rotational movement relative to

X and Y axes; Each bearing housing has one degree of mobility: rotation about the x axis.

This scheme contains three moving

20 links (), two kinematic pairs of the U-th class () and two kinematic pairs of the 1st class ().

The number of redundant connections in the pressure roller assembly is zero, since q W-6 n + 5 Py + 1-P-i-6-6 3 + 5-2 + O, which indicates that the pressure roller is self-reproducible with respect to the cylinder. Since the end pieces

The 30 roller bearing housings are cylindrical and forming movable joints with protrusions in the notches of the saddles, the distance between which corresponds to the diameter of the cylindrical parts of the housings, the pinching of the rollers at their distortions relative to the cylinders due to the cylinders and, therefore, eliminated

... the possibility of an additional 40

The target loads on the rollers and their bearings from inaccurate installation or manufacturing of these parts, which leads to the stability of the product clamping line in pairs, reducing the degree of destruction of the fibers and the elastic coating of the roller, and reducing the reliability of the exhaust device.

The design of this exhaust device reduces the time required for the manufacture of bearing housings and the installation of pressure rollers in the saddles and increases the reliability of the bearings and rollers by eliminating the extra effort that reduces the inequality of the exhaust tape.
