Description

f

The invention relates to mechanical engineering and is used to connect shafts in the transmission of torque.

The elastic clutch is known, containing a leading coupling half with cams on the end, a driven coupling half in the form of two concentrically placed shells with through slots and radially located between the cams of the driving coupling half.

The purpose of the invention is to increase the load and damping capacity of the coupling.

FIG. 1 shows the elastic coupling, general view; in fig. 2 shows section A-A in FIG. 1i in FIG. 3 shows an elastic element with an elastic filler in FIG. 4 is the same, with flat bearing surfaces and corrugations J in FIG. 5 - the same, with C-shaped elements of fixing the figure of springs

The elastic coupling consists of the leading coupling half 1 and the driven semi-coupling 2. The leading coupling half 1 has a hub with cams 3 at the end, and the knowledge of the coupling half 2 is made in the form of two concentrically arranged shells 4 and 5 with through slots 6.

8pazah 6 shells 4 and 5 placed the ends of the elastic elements 7, radially located between the cams 3 coupling half 1. Each elastic element is made in the form of two lamellar figure springs 8 with elements 9 fixation in the grooves 6 and placed between them a flat spring 10 with spherical projections 11 on ends placed between elements

9 fixing of the springs 8. The figured springs 8 may have convex bearing surfaces 12 or flat bearing surfaces 13 with corrugations 14. Elastic filler 15, for example, rubber, may be placed between the springs 8 and 10. Elements 9 fix000182

Spring 8 can be made in the form of rings 16 into which spherical protrusions 11 of springs 1.0 and shoulders 17 are inserted, supported from inside 5 on the surfaces of shells 4 and 5. Elements 9 of fixing springs 8 in slots 6 can also be executed as ends 18 C-shaped profile, directed in opposite directions from spherical protrusion

flat springs 10. Figured springs 8 may have a common closed profile (Fig. 3 and 4) or be made detachable (Fig. 2).

5 The clutch works as follows.

When starting the clutch, when dynamic loads occur, the cams 3 of the half-couplings 1 act on the supporting

20 surfaces 12 and 13 of the springs 8 of the elastic elements 7. In this case, the springs 8 are deformed, absorbing a part of the energy, and the spring 10 is bent due to the gaps in the connection and

5 also absorbs some of the energy.

The presence of the shoulders 17 and the elastic filler 15 contributes to the absorption of part of the energy of the dynamic impact due to compression. For this, the force from the cams 3 through the spring 10 is transmitted to the shells 4 and 5 and smoothly turns the coupling half 2.

If the clutch is made with C-shaped elements of fixation of figured springs 8, it works as follows.

When the cams 3 act on the supporting surfaces 12 of the elastic elements 7, the springs elongate and absorb part of the impact energy. The curved C-shaped ends of the springs 8 abut against the spherical protrusions 11 of the springs 10 and are displaced to absorb the impact energy. Then, through the spring 10, the moment is transmitted to the shells 4 and 5 of the half-coupling 2.
