Description

The utility model relates to elastic joints, namely, to couplings.

Couplings with elastic elements from a steel rope are known (Polyakov B.C., Barbash I.D., Ryakhovsky O.A. Handbook of couplings. - L.: Mechanical Engineering, 1979. - 344 s).

Closest to the proposed utility model in technical essence and the achieved result is the design of the coupling according to USSR patent No. 988198, Cl. F16F 7/14, 1983, comprising a driving and driven part, an elastic assembly interposed therebetween, supporting elements associated with the leading part in the form of buckets, supporting elements connected with the driven part in the form of rods included in the corresponding bucket. The elastic node is made of a cylindrical shape with two pairs of plates with holes and cable turns passing through them, which are coaxial and parallel to each other. One pair of plates of elastic cable assemblies is rigidly connected with buckets, and the other with rods (prototype).

Significant disadvantages of the known coupling are:

1. The complexity of the design, especially the supporting elements in the form of buckets, an elastic element with supporting strips.

2. Insufficient damping ability due to the limited number of cable segments and their work mainly on bending.

3. The inability to control the magnitude of the torque.

The technical results of the invention are simplicity of design, high damping ability and the ability to control torsional rigidity.

These technical results are achieved by the fact that:

1. The elastic unit with supports is made of bundles of a steel rope of cylindrical shape. For this, the holes in the supports of the beams under the ends of each rope segment are made parallel to the axis of the supports.

2. The supports of the steel rope bundles are placed directly between the drive and driven parts of the coupling and are fixed to them by fixing means, for example, using standard bolts, studs or screws.

In FIG. 1 shows an end view of a coupling; in FIG. 2 - longitudinal view of the coupling; in FIG. 3 is a view of bundles of a steel rope with supports (beam); in FIG. 4 is an end view of one of the beam supports with means for attaching the ends of the rope bundle; in FIG. 5 is a view of a longitudinal section of one of the supports with a rope bundle and means for attaching the ends of the rope bundle; in FIG. 6–9 are views of an embodiment of a coupling with three steel cable bundles and corresponding supports fixed on one side to the lead and, on the other, to the driven supporting elements made in the form of curly flanges. For clarity, the material of the leading and driven curly flanges is specially made of organic glass (Fig. 6-9).

The coupling contains a leading 1 and driven 2 parts (Fig. 1, 2, 6-9), an elastic-damping unit placed between them, made of bundles of a steel rope 3 (Fig. 1, 2, 3, 5-9) with supports 4, 5 (Fig. 1-9).

In FIG. 1-9 are indicated: 6, 7 - means for fastening the supports 4, 5 of the bundle 3 of the steel rope to the leading 1 and driven 2 parts of the coupling (Fig. 2, 6-9); B - ends of rope bundles (Fig. 1, 5); C is a means of attaching the ends of the bundle 3 of the steel rope (Fig. 1, 4-9); E - threaded holes (Fig. 2, 4, 5); D - holes for mounting means 6, 7 (Fig. 1, 2).

The coupling operates as follows.

When a torque is applied to the device, forces appear that act in the transverse plane of the elastically damping rope bundles 3 (Figs. 2, 6–9). The resulting relative displacements of the leading 1 and driven 2 (Fig. 1, 2, 6-9) parts are eliminated due to the deformation of the elastic damping rope bundles 3 (Fig. 1-4, 5-7). Leading 1 and slave 2 support elements are interchangeable (Fig. 1-3, 6-9).

Variation of the elastic-damping characteristics of the coupling is achieved by increasing or reducing the number of rope bundles 3 without replacing the leading 1 and driven 2 parts of the coupling (Fig. 1, 2).

Preliminary static tests of the prototype coupling (Fig. 6-9) showed high elastic-damping properties of the bundles of 3 steel wire segments.

An analysis of well-known technical solutions in this field and in related industries shows that such a coupling design with the indicated features, advantages and distinctive features is not available.
