FIG. f –n

The invention relates to mechanical engineering, mainly for connecting misaligned shafts in the drives of rolling mills.

The purpose of the invention is to increase the load capacity by ensuring the nominal position of the rolling elements. .

.In FIG. 1 of Fig. 1) a device for coupling shafts, a general view, in FIG. 2 shows section A-A in FIG. one; in fig. 3 is a view B in FIG. 2; in fig. 4 shows a section B-B in FIG. 2.,

The device for connecting the shafts contains two coupling halves 1 and 2 placed between the coupling halves perpendicular to the axis of the coupling pin 3 with a spherical centering lug 4 in its middle part, rolling body 5 located on the finger 3 on both sides of the spherical lug 4, discs 6 mounted at the ends of the finger and connected to the half-tufts 1 and 2 by means of a gear 7.

In order to increase the service life of the device, each rolling body 5 can be made of a composite of at least two parts mounted on the finger 3 with the possibility of relative rotation. In the plane perpendicular to the axis of the finger 3 between the coupling halves 1 and 2 there is an insert 8..

The device works as follows.

Torque is transmitted, for example, from coupling half 1 to coupling half 2 via rolling bodies 5. The magnitude of the swinging movements depends on the distance on which the corresponding rolling body 5 is located from the center O of the spherical protrusion 4 of the finger 3 (the center of the joint), therefore

the rotation of the various parts of one rolling body 5 occurs at different angles, which reduces the amount of their sliding along the surfaces half a foot.

By supplying the joint with a finger with a spherical centering protrusion in its middle part and two disks, the rolling bodies on each finger. side of the spherical protrusion and the installation of the disks on the ends of the finger and their connection with the coupling halves by means of the gearing increases the load capacity of the coupling, and due to

rolling of composite bodies - increased service life.
