Description

The invention relates to the field of mechanical engineering.

Known cross-rocker coupling containing two coupling halves and an intermediate element with two mutually perpendicular ridges included in the grooves of the coupling half £ ΐ3.

This coupling compensates axial displacement of the shafts, but does not possess elastic properties.

Also known cross-rocker coupling containing two coupling halves with diametrical grooves on the ends and located between the coupling halves, the intermediate element [2 ^.

This device is closest to the invention to the technical essence of the achieved effect.

However, this coupling has insufficient elastic properties in the circumferential direction and load capacity.

The purpose of the invention is to increase the elastic properties and load capacity.

This goal is achieved by the fact that the intermediate element of the coupling is made in the form of a rod bent around the circumference, straight ends

which are arranged at an angle of 90 ^e to each other and arranged in the slots of the coupling halves.

FIG. 1 shows the coupling, common

5 view; in fig. 2 and 3 - embodiments of the intermediate element.

The coupling consists of two interchangeable flange coupling halves 1 and 2 with diametrical grooves 3 and 4 at their ends and an intermediate element 5 made in the form of a rod curved around a circle with a radius, the ends 6 and 7 of which are bent and arranged at an angle of 90 ° to each other. Eleg ment ment 5 is made of spring steel and may be in the form of a circle or square. Its bent ends 6 and 7 intersect in the center of the coupling, form a crosspiece and are located, respectively, in slots 3 and 4 of the coupling half. The elastic element 5 can also be made in the form of a figure-eight curved ring, as shown in FIG. 3. To increase the rigidity of the section of the intermediate element at the point of mutual intersection of the perimeter at points 8, 9, 10, 11 and 12, they can be additionally interconnected, for example, by welding.

This element encompasses the flanges of the coupling halves 1 and 2 on the outside, with a small guaranteed clearance of 8, which can compensate for the radial displacements of the shafts. With an appropriate choice of the radial clearance, the intermediate element can simultaneously serve as a limiter for the limiting displacement of the coupling halves.

The coupling works as follows. When rotating the coupling half 1, it carries into the movement the protrusion 6 of the intermediate element 5, which through the ledge 7 carries the coupling half 2 into rotation. Since the intermediate element 5 is located outside the coupling half 1 and 2, and its protrusions are located in the slots 3 and 4, it is possible to bring the ends of the coupling half together. As a result, the coupling length is reduced. In addition, the fabrication of the intermediate element is simplified, and its elasticity increases the elastic properties of the coupling.
