The invention relates to mechanical engineering.

The chain of the invention is an increase in compensatory properties.

Fig, 1 shows a clutch cut; FIG. 2 is a section A-A in FIG. 1,

The elastic coupling consists of coupling half 1 with holes on the hub 2 and coupling half 3 with holes on the rim A, the coupling half are connected by a roller 5 to the outer cylindrical surface, on the cylindrical surface of the roller 5 are mounted 6-speed sleeves, on the outer surface of the lower step and on The inner surface of the larger hub is filled with holes. The sets of elastic rings 7 and 8 with holes along the outer and inner surfaces are installed between the smaller step of one clip and the larger step of the other clip. In the combined holes of the hub of the rim, the inner and outer diameters of the elastic rings, the outer surface of the smaller diameter of the clip and its inner surface of a larger diameter. 9 rolling bodies are installed.

The elastic reversible coupling works as follows.

During the rotation of the half-coupling 1, it carries away the rolling bodies 9, which, rolling in the holes of the hub 2 and the elastic ring 7, bend the ring sectors in the sheets weakened

by the holes.

As the angle of rotation of the coupling half 1 increases and the sectors of the elastic ring 7 bend, the rigidity of the latter increases and the torque is transmitted to the elastic ring 8. Rotating, the ring 8 carries the rolling bodies 9 mounted in the aligned holes of the ring 8 and the steps of the larger diameter of the holder 6. , force-, p rotate the yoke 6. Then the bodies (the rolls installed in the combined holes of the same yoke are smaller than 15

diameter and the elastic ring 7 in the adjacent set of elastic rings, transmit rotation through the rolling bodies to the elastic ring B and then to the next lying cage and t, d, until the coupling half 3 rotates

Since the radius of the holes is larger than the radius of the rolling elements, the torque is transmitted gradually. As the sectors of the elastic ring are bent and, depending on the elastic properties of the ring material and their quantity, a clutch with the required damping properties can be created. By performing stepped clips, the damping capacity of the coupling can be increased without increasing the diameters of the coupling halves.

This coupling design makes it possible to obtain virtually any damping and compensation properties, which will allow better damping of points and impacts when load changes on shafts, protect the mechanism from resonant and torsional vibrations, compensate for the displacement of connected shafts, and overcome the moment of inertia when the machine is started.
