Claims

The coupling consists of a leading coupling half 1 with projections Z at the end and coupling half 3 with projections 4 on the side surface. Half coupling 3 has a square flange with a side of square a, and its protrusions 4 are made in the form of equal angles of length C, which cover the adjacent faces of the square flange and are fixed to them with screws 5. The projections 2 of the coupling half 1 are made of plates welded to its end face b, which form a cross between each other. Between the projections 2 of the half coupling 1 and the projections 4 of the coupling half 3 are located, elastic, for example rubber liners6, which rest on the faces of the projections 2 and 4. Elastic inserts 6 can be made in the form of square shields, round, solid or hollow rings, octagon, thin metal rings. The dimensions of the inserts 6 are selected in such a way that when screws 5 are tightened between the lugs of the coupling halves, a preload is formed that excludes a backlash in the coupling. The width of the bushings b is taken to be somewhat greater than the width B of the protrusions 2. The coupling works as follows. When rotating the leading half coupling 1, for example clockwise, it is ledges 2 with forces P exerts through bushings 6 pressure on the ledges 4 of the driven coupling half 3, causing it to rotate. In this case, under the action of the applied force P, the elastic deformation of the liners 6 occurs, thereby ensuring the elasticity of the transfer of the load between the coupling halves and the damping of dynamic loads and vibrations. Since the protrusions 4 are made in the form of removable angles fixed on the edges of the square flange with screws 5, the design of the coupling is greatly simplified, there is no need for planing work, since parts 4 are made of a standard corner or strip, the assembly of the coupling does not require axial displacement of the shafts, which simplifies installation and repair. All liners 6 take part in the work and their volume increases, which increases the damping properties of the coupling. Claims. A damping coupling comprising two coupling halves with protrusions and elastic elements arranged between them, characterized in that, in order to simplify the design and operation, the projections of one coupling half are located at its end, and the protrusions of the other coupling half are located on its lateral surfaces.

2. The damping coupling according to claim 1, characterized in that the half couplings are square in cross section perpendicular to the axis of the coupling, the projections on the end of the coupling half are mutually perpendicular, and the projections of the other coupling half are made in the form of isosceles corners and fixed on its corners with screws.
