The invention relates to a machine tool building and can be used for coeAHHeHtiH of machine shafts.

The purpose of the invention is to increase the reliability and durability by ensuring the possibility of adjusting the stiffness of the coupling.

In Fig. 1, the image shows a elastic elastic coupling, a longitudinal section; FIG. 2 is a sectional view on FIGI; FIG. 3 is the same; -a variant with an increased number of rings.

The elastic coupling consists of semi-coupling 1, covering them 2, elastic their intermediate elements made in the form of rings 3 "In the longitudinal cylindrical grooves 4 coupling 1, pairs of wedge 5 and b are installed, the contact between them is The conical surfaces, Blad 6, are connected to the lateral surfaces of the disks 7, which are fastened to the couplings 1 and axially displaced by bolts 8. Between the coupling halves 1 and the yoke 2 there are groups of rings 3 arranged in two rows. Rings of one row, in contact with 2 grooves 9 made in the cage and two adjacent rings of another row. The rings of the latter are located in the recess 10., made in the wedge-liner 5 and are in contact with the adjacent rings of the nerve- .- o r yes rings ..-.

The outer surface of each coupling half is spherical in longitudinal section to compensate for the angular displacements of the field; / t Uft 1

The axial displacement of the insert is 5 seconds, the rings 3 are guided by stops 10, located in the slots of the coupling halves 1 on the inner side.

Elastic coupling works as follows.

When screwing the bolts 8, the disks 7 are displaced in the axial direction, together with which the bushings 5 are moved. Due to the oppositely directed conical contact surfaces of the insert 5 and 6, the axial displacement of the bushings 6 causes the radial movement of the bushings 5. Due to the forced movement of the bushings 5 into radially direction of the deformation occurs. elastic rings 3. Installation of elastic

the intermediate elements in the form of rings 3 allow for the possibility of angular displacements of half an uft 1 one relative to the other and the holder 2, as well. adjust the stiffness of the coupling.

When torque is applied from the left half of the coupling 1, it is transmitted through the left elastic rings 3 to the holder 2, from go around) 2 the moment is transmitted to the right groups, rings 3, and from them to the right coupling half 1. Elastic deformations occur relative to each other in the first transitions of coupling 1 rings 3 in places of coupling of parts of half couplings 1 with holder 2, the presence of elastic intermediate elements. in the form of rings 3 in the coupling allows to reduce ai-i-n, plt udy of the moments of elastic forces due to the mechanism in transitional 5 shams in the presence of gaps in the elements of the drive line, as well as in the presence of external dynamic loads and periodic torques. With this--; Some of the perturbing moments are absorbed by the internal I external friction of elastic spaced elements: s and the environment is scattered.
