The invention relates to construction maui, in particular devices for transmitting rotation.

The weight of the coupling is two, concentric with two concentric chumufta with memei; iihi ui slots and intermediate e-temps 1 located in them.

The goal of the acquisition is to increase the Haip 3 () - iiiOH ability.

This is achieved by the fact that the grooves of the inner no.1 m; 1; performed parallel to the axis of the u-pi. :. : pn; .e KVTO4Hijie elements have (Pg; rm, LiK / rrv-; the first form is combined Hijix called iio.ly.vivty.

External nolufufta 2 is fixed on the shaft 1, in which the methods of electrochemistry or electric erosion, ensure the accuracy of 0.03-0.05 mm. the lateral grooves are removed. 3. evenly spaced around the circumference. The grooves 3 in the macrodigital direction are filtered in the arc of a circle centered at the intersection of the n-axis axis of the device and the mid-plane. The transverse sectional grooves 3 have the shape of circular arcs whose radii decrease

but to the KOIHUTM direction, respectively, to the arc (s), profiling these elements in the longitudinal direction.

When IlepoKoerix osaG, 1s 1 and 6, the intermediate j.ieMCiyi,.; -, slide along the surface of the grooves 3 to,:

through the joint axis, which prevents the wear of the mating elements. With all the angular misalignments of the axes of the shafts, the surfaces of the intermediate elements 4 are in contact over the entire surface of the grooves 3, which reduces their wear.

The use of the invention in mechanical engineering will make it possible to eliminate coupling failures in operation with shaft misalignments and to increase the service life and reliability of machines, in particular, power plants.
