Description

(54) HIGH-ELASTIC COUPLING

The invention relates to mechanical engineering and can be used to connect the shafts of machines and mechanisms when they are skewed.

A known elastic coupling comprising two flange coupling halves with inlet screw channels interacting through a toroidal elastic element fixed to them.

Its disadvantage is the complexity of the design.

Closest to the invention is an elastic coupling comprising two flange coupling halves and an elastic element fixed to the coupling halves by means of pressure rings 2.

However, the known device is characterized by low durability, lack of reliability of fasteners due to the possibility of slippage between the elastic element and the flanges of the coupling halves.

The purpose of the invention is to increase the service life.

The goal is achieved by the fact that the coupling, containing two flange coupling halves, interconnected by a toroid-shaped rubber-cord sheath, fixed on the coupling halves by means of pressure rings, is equipped with pins fixed evenly around the circumference on the facing one / to the other end of the flanges of the coupling half, in an elastic shell in the fastening zone, blind holes are made with the half UFs, the pins being installed in the aforementioned holes without radial gaps, and the dimensions of the hole and the pin are interconnected by the following expression m:

The clutch contains coupling halves 1 and 2, connected by an elastic element 3, made of a toroidal shape made of rubber-cord material. In the fastening zone of the elastic element with flanges half coupling 1 and 2 are made

Claims (2)

Claim Ϊ, Highly flexible coupling containing two flanged half-couplings, interconnected by a toroidal rubber-cord-sheath, fixed to the half-couplings by means of pressure rings, characterized in that, in order to increase reliability, it is equipped with pins fixed uniformly around the circumference of the inverted one to the other ends of the flanges of the coupling halves, blind holes are made in the elastic shell in the fastening zone with the coupling halves, while the pins are installed in said holes without radial clearances. 2. Coupling pop. 1, characterized in that the dimensions of the holes and the pin are interconnected by the following expression: where a is the difference between the serving. pin part and hole depth; (C is the diameter of the pin ·, <& 2 ~ the diameter of the hole; n is the depth of the hole’s.
