. The invention relates to mechanical engineering and can be used to connect the power shafts of machines and mechanisms under the conditions of their radial and angular displacement, or a combination thereof, for example, in the drive of the combine cutting drum.

 The purpose of the invention is to increase by. reliability and durability due to improved elastic and compensating properties.

Fig. 1 shows an elastic compensating coupling, a longitudinal section of Fig. 2 shows a half coupling, a general view; on fig.Z - elastic element.

The elastic compensating coupling consists of two identical coupling half 1 and 2 and four wavy elastic elements 3 and 4, made in the form of ring sectors with the ends bent in mutually perpendicular planes,

Elastic element 4 - a mirror image of the elastic element 3,

The coupling halves contain two diametrically located protrusions 5 on the front surfaces of the disks and grooves 6 cut through the disks of coupling half 1 and 2 Rotated relative to the projections 5. 90 around the axis of the coupling half. The grooves 6 of one half-coupling are located opposite the projections 5 of the other half-coupling, and the elastic elements 3 and 4 can be made of individual plates or a set of plates and with their ends placed in the adjacent grooves 6 of the coupling half 1 and 2 / Elastic elements 3 and 4 can also be rigidly connected between in the places of their contact, which increases the durability of the coupling by reducing friction pairs.

The clutch works as follows.

the half coupling is provided with limiting axial displacement of the ends of the ring sectors, made in the form of axially directed cams.

Torque is transmitted from half coupling 1 to half coupling 2 through four elastic elements 3 and 4, which are Ring sections made as separate plates or as a set of them and placed at the ends in grooves 6 of adjacent coupling half 1 and 2, With a sharp change in the torque moment, the half-coupling 1 rotates through a certain angle relative to the half-coupling 2. When this happens, the elastic elements 3 work on stretching, i.e. they seek to ensure that

the annular sector of the given elastic element has become direct, and the elastic elements 4 are in compression. Due to availability. the protrusions 5 of one coupling half opposite the grooves 6 of the coupling half, the elastic elements 3 and 4 are prevented from falling out of the grooves 6 of coupling half and 2, as well as moving them in the axial direction,

To compensate for the radial displacement of the connected shafts, the elastic elements 3 and 4 have the possibility of radial displacement by the value of ft-gap between the depression of the protrusion

3 of one of the half couplings and elastic elements 3 and 4, corresponding to the magnitude of the radial displacement of the connected shafts.

To compensate for the angular displacement

of the connected shafts, the minimum clearance L is specified between the cam of the protrusion 5 of one of the coupling halves and the plane at the contact point of the elastic elements 3 and 4, which can be determined from the following expression
